19601 HOWARD, STUDIES IN THE GENUS COCCOLOA. IX STUDIES IN THE GENUS COCCOLOBA, IX. A CRITIQUE OF TlHE SOUTHT AMERICAN SPECIES RICHARD A. HOWARD THE FIRST SIX PAPERS of this series treated the West Indian species of the polygonaceous genus (occoloba, with the work based largely upon field studies in this area. The seventh paper dealt with the species of Central America and Mexico; the writer has only a slight knowledge of these species in the field, but fortunately had available an unusually large number of collections as well as extensive field notes made by recent collectors. This paper will treat the species of South America. The limita- tions of this study are greater both from lack of field knowledge and the fewer specimens available. For these reasons, this treatment is probably more conservative than future workers will deem necessary. The goals of this study have been 1) to bring together all records of taxa of Coccoloba for South America: 2) to correct existing errors of literature citation: 3) to evaluate and compare published species where possible: 4) to locate the existing type collections; and 5) to select lectotypes of many species. It is hoped that these notes will encourage collectors and botanists in the area to gather complete material of the species and to record adequately the variations so as to allow a better understanding of certain morphologi- cal problems. Only then can the monographer prepare complete descrip- tions and keys for the species in South America. The earliest comprehensive treatment of the species of Coccoloba in South America was prepared by Mleisner for the Flora Brasilicnsis (5(1): 23-44. 1855). Although some species were illustrated, the descriptions in general were inadequate and no keys were given. Specimens cited previ- ously from the Martius herbarium have since been found in Brussels, Munich, and Leningrad, and a few numbers have been widely scattered. Representative specimens of several species attributed to Martius could not be located for this study and in some other species the selection of a lectotype has required very careful comparisons between specimens from several herbaria and published descriptions. In 1856 Meisner provided a synopsis of the genus for Ie('andolle's Prodromus (14: 150-171). One might expect that many of the speci- mens which Meisner cited would be in the Prodromus herbarium or in the Delessert herbarium at Geneva. but, unfortunately, very few are repre- sented in either collection. Meisner's personal herbarium, which has been acquired by the New York Botanical (arden, includes specimens of most species of Coccoloba. A few of these are small fragments, yet they repre- sent the only existing type material for certain species. The only complete monograph of Coccoloba was prepared by Lindau JO) RNAL OF THE ARNOLD ARBORETL' M and published in 1890 in Engler's Botanischcr Jahrbiichcr (13: 100 229). Mianv adjustments are necessary therefore to bring the specific names into conformity with the present rules of nomenclature. Lindau's de- scriptions are not models of accuracy, and the key published in the mono- graph contains so many errors of fact that it is almost unusable. Fol- lowing the description of a plant. Lindau cited the collector's name and collection number and at the end gave a list of the herbaria in which he had seen the material. In the selection of a lectotype. therefore, it has been necessary to associate the collection with a particular herbarium. The information supplied in this paper should make easier the work of the next monographer who wishes to obtain material for study. Lindau frequently cited specimens to be found only in the Berlin herbarium. A study of these, annotated by Lindau, has shown them to be fragments of specimens from other herbaria. There is a question whether the holotype is really the Berlin fragment and only specimen the author cited, or the more ample specimen in some distant herbarium which the author may not have seen and did not annotate. The specimens of Coccoloba in the Vienna herbarium were lost or de- stroyed during World War II. According to Lindau's citations some of the Jacquin material was at Vienna and is no longer available. A very few of the Vienna specimens were photographed before 1940, and prints of these in the herbarium of the Chicago Natural History Museum are the basis for discussion of these names here. Most existing treatments of the genus have assumed the flowers to be perfect. During field study of the species in the West Indies the author determined that the flowers are functionally unisexual and that the plants are dioecious. Recently Buchinger and Sanchez examined the species found in Argentina and concluded (Bol. Soc. Argent. Bot. 7: 251 255. 1905) that one species of ('occoloba in that country is truly dioecious. but that the remainder have perfect flowers or are monoecious. Very few col- lections are cited in their work and none of those was available to me. I have examined many specimens which I assign to these same species from Argentina and find no evidence in the herbarium specimens to sup- port their conclusions. In the specimens which I examined the ilowers with conspicuous pistils have small or rudimentary stamens which do not produce pollen. Flowers with large stamens which produce pollen appear to have undeveloped or rudimentary pistils. There were no specimens with pollen-producing flowers and fruits on the same branches. I do not doubt their decision, since it was based on field study of carefully selected material. but I do poin t out the difficulty of stating definitely the sexual condition in herbarium specimens and the futility of using in a key such contrasting characteristics as plants monoecious or plants dioecious. The species in the \est Indies were studied in the field to determine leaf variation. I found that vigorous terminal shoots, short branches. branches of average growth. and adventitious shoots might all have dif- ferent sizes andt shapes of leaves. This leads one to question Lindau's V\L. XLI 1960] HOWARD, STUDIES IN THE GENUS COCCOLOBA, IX 215 descriptions and keys, since he seems to have relied much on the size and shape of leaves and particularly on the shape of the leaf base. The habit of the plant also was found to be variable in West Indian species. Some are shrubby or tree-like at the base, but with scrambling branches having the appearance of lianas. Thus herbarium specimens consisting of flowering or fruiting branches without adequate habit notes may not be indicative of the true character of the species. Relatively few of the South American species considered in the follow- ing notes are represented by both flowers and fruit. In some cases it has been possible to associate as one taxon certain flowering and fruiting specimens originally described as separate species. When peculiarities of growth can be properly associated with flowering and fruiting specimens additional species will undoubtedly be combined. Throughout the fol- lowing text I have been conservative in maintaining as distinct species all specimens concerning which there may be some question. When fur- ther evidence becomes available, many of these species may be united. I have been fortunate to have on loan for study the important historical collections of Coccoloba from the Botanisches Museum, Berlin. which formed the basis for Lindau's work; the Jardin Botanique de l'E:tat, Brussels, which include many Martius collections; the Botanische Staats- sammlung, Munich, also rich in Martius material; the New York Botanical Garden which include recent collections, as well as Meisner's personal herbarium; and the Herbarium of the Department of Systematics and Plant Geography of the Botanical Institute of the Academy of Sciences of the U.S.S.R., Leningrad, which contains so many duplicates of classic collections. I am most grateful to the directors and curators of these institutions for making their collections available for an unusually long period of time. Selected collections have been borrowed from other insti- tutions and I have visited still more herbaria for study. The many cour- tesies which made this publication possible are much appreciated. The standard abbreviations of Index Herbariorum have been used in this paper. Species of Coccoloba have been reported from every country in South America, with the sole exception of Chile. In the citation of specimens the countries and their subdivisions, as well as the specific localities of collections, are listed in alphabetical order. Coccoloba acrostichoides Chamisso, Linnaea 8: 132-133. 1833: Meis- ner, Fl. Bras. 5(1): 33. pl. 13, fig. 2. 1855; Lindau, Bot. Jahrb. 13: 138. 1890. Coccoloba rubiginosa Martius ex Meisner, Fl. Bras. 5(1): 33. 1855, in syn. Chamisso did not cite a specimen in the original description, and pre- vious monographers have not indicated a type. There is a specimen in the Leningrad herbarium collected by Sellow and bearing on the label the name "Coccoloba acrostichoides N" and the annotation "Hb. Cham." This specimen is probably authentic. A more ample specimen in the Berlin herbarium has a tag which bears the number "1393" attached but lacks JOURNAL OF THE ARNOLD ARBORETUM the reference to the Chamisso herbarium. Lindau did not see or cite either of these collections, yet one must be considered the lectotype and I so designate the specimen at Berlin. All other Sellow collections, including those cited by Lindau, are annotated "Corcoloba acrostichoidcs (ham. et Schl." The illustration in Flora Brasiliensis well represents this species. A printer's proof of this drawing is in the Brussels herbarium and the speci- men Claussen 330 is mounted on the same sheet. There is little similarity between the two, and the illustration appears to be a compilation. Coccoloba acrostichoides is one of the most distinctive species of the genus, with copious dark-brown pubescence on the lower leaf surface. In leaf shape and in the nature of the inflorescence it is similar to C. brasili/nsis. The species is not known in fruit and I have not seen any collections more recent than those of Glaziou. 'occoloba rubiginosa Martius ex Meisner was published in synonymy and has no validity. A specimen at Munich from the Martius herbarium bears this name. but no location or collector is indicated.

I discussed this species in an earlier paper (Jour. Arnold Arb. 40: 185. 1959) when I concluded that the amount of pubescence on the plant varied with the age and the vigor of the specimen. I cannot find any value or significance in the two varieties Lindau published. A specimen from the Brazilian state of Pari, Huber 4393, bears an unpublished herbarium name attributed to Huber. The specimen is clearly referable to synonymy here. A collection in the herbarium of the University of Wisconsin numbered "45" but without collector was supposedly made in La Lima. Chile.

Weddell based this species on Gardner 1389 from the state of Alagoas, Brazil. At present I am unable to determine the relationship of this species to Coccoloba obtusifolia Jacq. and C. peruviana Lindau. A full discussion will be found under C. obtusifolia.

Jahrb. 13: 198. 1899. Lindau accepted the Weddell name for this species, although he cited in synonymy the epithet Casaretto published several years earlier. Casa- retto did not cite a specimen in the original publication, but it seems clear to me that the description and data given are based on his collection numbered 1194. This collection consists of two sheets in the Turino her- barium and I have designated one of them as the lectotype. There is a possibility that the older epithet Coccoloba firma Martius ex Colla (1836) is the correct one for this species. The current difficulty in determining the type of C. firma will be discussed under that name. Brazil. BAHIA: Blanchet 1486 (c, G-type collection of C. populifolia); Sel- low 1137 (B), 793 (B).

The previous paper in this series (Howard, loc. cit.) contains a dis- cussion of the nomenclature of this species. For the present, the type is considered to be the Vellozo illustration. After a careful study of this species in the field it may be desirable for some future monographer to select a modern specimen as neotype. JOURNAL OF THE ARNOLD) ARBORETUM Brazil.

He re- ferred to material collected by MI. Rigou in 1902 from the station "Mar- gherita." Prov. Santa Fe. and to material collected the following year in Reconquista.

As long as there is a possibility that the original material may be located, a neotype should not be selected. In their recent paper Huchinger and Sanchez cite only one collection. Schulz 240. which I have not seen. They further consider the species to be endemic to the (Chaco territory and to be found only in the provinces of Salta and Chaco. thereby eliminating the locality of the type collection. The material cited below appears to me to correspond with the original description. (Coccoloba argcntinensis is easily recognized by the small obovate-elliptic leaves, the long fruiting pedicels, and the flowering of the plant before the leaves are fully developed. (occioloba pracco. Herter was distinguished on these same characteris- tics but without comparison with the present species. I have examined an isotype and conclude that the reduction of C. praccox to the synonymy of C. argentinensis is necessary.

Arnold Arb. 40: 72, 73. 1959), I selected a specimen from Martinique. Hahn 1005, in the Berlin [VOL. XLI 1960] HOWARD. STUDIES IN THE GENUS COCCOLOBA, IX 219 herbarium as the lectotype. The species is well represented in the Lesser Antilles from Guadeloupe south to Trinidad. Lindau (Bot. Jahrb. 13: 156. 1890) cited specimens only from Guadeloupe, Martinique and Brazil. Eyma (Meded. Bot. Mus. Utrecht 4: 110. 1932) mentioned the dis- tribution of the species as "Guyana. Brazil, Guadeloupe, Martinique." I have seen neither the specimens cited from the Guianas (B.W. 6560. 6600, and possibly B.W. 6490 and 6550b) nor those Lindau cited from the states of Para and Govaz in Brazil (Burchell 8034, 9345 and Gardner 3966). On the basis of an unnatural range I question particularly the Brazilian determinations given by Lindau. Future workers with addi- tional material at their disposal doubtless will check the relationship of Coccoloba ascendcns and C. sparsifolia. Coccoloba barbeyana Lindau, Bot. Jahrb. 13: 185. 1890. I have examined the single collection cited by Lindau (Ruiz & Pavon s.n., Peru, without definite locality, in the Barbey-Boissier herbarium) and failed to find the holotype or the species distinct in any way from Coccoloba densifrons Martius ex Meisner. Although Lindau accepted C. densifrons (based on a Martius collection from Ega in the Brazilian Amazon) he did not list the epithet in the key to the species. Coccoloba billbergii Lindau, Bot. Jahrb. 13: 219. 1890. Lindau cited "Coccoloba obtusifolia Meissn. (non Jacq.)" in synonymy when he described C. billbergii based on Billberg 204 and 204a from Carthagena, implying that Meisner was in error. However, Meisner noted both the similarity of these Billberg collections to C. obtusifolia, as de- scribed and illustrated by Jacquin, and the discrepancy in the specimens so labeled in the Willdenow herbarium and the reference in the Willdenow catalogue. Lindau chose to interpret C. obtusifolia on the basis of the specimen in the Willdenow herbarium and incorrectly to consider C. ob- tusifolia as a species from the West Indies. I have examined the Billberg collections cited by Lindau from the Berlin and Stockholm herbaria. These are correctly associated with C. obtusifolia Jacq. as a South Ameri- can species. Coccoloba billbergii Lindau must be considered a synonym of C. obtusifolia Jacq. "Coccoloba obtusifolia" as used by Lindau (loc. cit. 146, 147) is cor- rectly assigned to synonymy under C. microstachya Willd. (Howard, Jour. Arnold Arb. 38: 217-219. 1957). Coccoloba blanchetiana Weddell, Ann. Sci. Nat. III. 13: 257. 1850. Weddell cited Blanchet 3561, from near Jacobina, Bahia, Brazil (G, P). This species is to be referred to the synonymy of C. ochreolata Weddell and will be discussed there. JOURNAL OF THE ARNOLD ARBORETUM Coccoloba bolivarana Llewelyn Williams, Trop. Woods 68: 39. 1941. In a list of the forest trees of Venezuela, Williams refers to "Brusquillo Blanco, Coccoloba bolivarana (a new species), a tree about 8 m. high, growing in rocky areas, with a trunk ramified from the base, and bearing a juicy, lustrous black fruit." The species has not been published validly with a Latin description, to my knowledge, and the brief description given above is scarcely to be considered diagnostic in this difficult genus. Specimens in the herbaria of the Chicago Natural History Museum and the Royal Botanic Gardens, Kew, bear this name but attribute it to Stand- ley. The specimens (Williams 13374) were collected at El Tigre, Los Garzones, on Rio Cuchivero, Bolivar, Venezuela. They cannot be assigned to any recognized species and will be described in a later paper. Coccoloba bracteolosa Meisner, Fl. Bras. 5(1): 30. 1855. No type was selected in the original description, but a Martius collec- tion without number from Joazeiro. on the Rio San Francisco, in Bahia. Brazil, has been photographed by other workers in the Munich herbarium and distributed as the type. I am referring this species to the synonymy of Coccoloba ochreolata Weddell and will discuss the problem under that name. Coccoloba brasiliensis Nees & Martius, Nov. Act. Acad. Nat. Cur. 11: 30. 1823; Meisner, Fl. Bras. 5(1): 32. t. 13, f. 1. 1855. Coccoloba senaei Lindau ex Glaziou, Bull. Soc. Bot. France 58: 571. 1911. The original description cites first the locality of "X Valos" and then a general littoral distribution in Bahia, "Maragnanum" and Para, the latter attributed to Martius. I have seen no Martius specimens which fit the original description among the material from the Martius herbarium now at Brussels, Leningrad, or Munich. In his treatment of the genus for Flora Brasiliensis, Meisner redescribed the species and cited collections by Prince Maximilian and Martius. The illustration in Flora Brasiliensis is based on the specimen collected by Prince Maximilian and I select this as the lectotype. A previous worker, possibly Meisner, has annotated some sheets to in- dicate a similarity to or a relationship with Coccoloba rigida Meisner. (Lindau, not following the homonym rule, accepted C. parvifolia Schott 1827, not Poiret 1804. and included in synonymy C. rigida Meisner.) Lindau distinguished between C. brasiliensis and "C. parvifolia" on the puberulent inflorescence axis in the latter species and the glabrous one in C. brasiliensis. An examination of the specimens cited below will show that the stem, ocreae, petioles, and frequently the base of the leaf blade are puberulent to short pilose in C. brasiliensis. The bracts and ocreolae of the inflorescence are likewise slightly puberulent to glabrous. On the characteristic of pubescence there is scant reason for separating C. brasi- [VOL. XLI 1960] HOWARD, STUDIES IN THE GENUS COCCOLOBA, IX 221 liensis and "C. parvifolia." However, the leaves of C. brasiliensis are vari- able in size and shape. In the type, and in the most recent collections, the leaves are thicker in texture and the bases are rounded-cordate, in contrast to those of "C. parvifolia." The inflorescence of the type is as compact as that of "C. parvifolia" but recent collections show longer, more lax inflorescences in which the ocreolae do not expand with the developing flower buds, and are, in fact, shorter than the bracts in all stages of de- velopment. Until these characteristics can be evaluated by field studies it seems desirable to retain C. brasiliensis as a species distinct from C. rigida. The several sheets of the collections by Glaziou cited below suggest that the existing descriptions of Coccoloba brasiliensis are unsatisfactory and must be changed to accommodate the narrow, lanceolate-oblong leaves of the vigorous shoots and the large, oblong, but sessile, leaves of adventitious shoots. The Glaziou collection without number in the Paris herbarium has some leaves with blades 18 cm. long and 9 cm. wide. The largest leaf on the lectotype is 4 cm. long and 2.3 cm. wide, yet the col- lections cited below show all intermediates between these extremes. The phrase "Coccoloba senaei Lindau n. sp." is used by Glaziou in a list of determinations of his collections. The brief description "Arbuste sarmenteux, fl. blanchatres" can scarcely be considered diagnostic in this genus and I consider C. senaei to be a nomen nudum. Brazil.

This epithet is a later homonym of Coccoloba brasiliensis Nees & Martius. The species was based on a Sellow collection from Brazil which I have not seen. The description is not that of a species of Coccoloba. It was referred to the genus Hedyosmum of the Chloranthaceae by Cha- misso (Linnaea 4: 36. 1833). I have not determined whether this is the same as Hedyosmum brasiliense Mart., recognized by Occhioni in his recent monograph of the genus (Contribuccao ao estudo de familia Chloranthaceae com especial referencia ao genero Hedyosmum Sw. Rio de Janeiro, 1954). Coccoloba candolleana Meisner, Fl. Bras. 5(1) : 41. 1855. Meisner based this species on the collection Blanchet 1818 from Bahia, Brazil. He noted its similarity to Coccoloba cordata Chamisso. I am unable to distinguish the two and so refer C. candolleana to the synonymy of the older name, C. cordata. Lindau (Bot. Jahrb. 13: 201. 1890) cited Goudot 4, from Colombia, in JOURNAL OF THE ARNOLD ARBORETUM his treatment of Coccoloba candollcana. Several recent collections from Colombia have also been identified as this species. The Goudot specimen in the Berlin herbarium cited by Lindau is a fragment of a larger speci- men in the Paris herbarium. A study of the latter sheet clearly indicates that this collection is to be referred to C. padiformis Meisner, the type of which is from Caracas, Venezuela. Coccoloba caracasana Meisner, )('.

Coccoloba cyclophylla Blake is now added to the synonymy of this species. Blake compared his species, based on Curran 47, from Colombia. with one from Hispaniola and concluded that they were distinct.

Coccoloba caurana Standley. Field Mus. Publ. Bot. 22: 73. 1940; L. Williams. Explor. Bot. Venez. 189. 1942. Although the description of this species was published twice as new. the taxon belongs in the synonymy of Coccoloba fallax Lindau and is dis- cussed in more detail under that name. The type, in the herbarium of the Chicago Natural History Museum, is Wlilliams 11366, from Venezuela. VOL. XLI 1960] HOWARD, STUDIES IN THE GENUS COCCOLOBA, IX 223 Coccoloba cerifera Schwacke, P1. Nov. Mineir. 1: 7. 1898. I have not seen the original publication to check the validity of this name and so, for the present, must interpret the species from the speci- men indicated as the type in the Berlin herbarium. The plant is unlike any other species found in southern Brazil. It resembles Coccoloba schom- burgkii in the shape and thickness of the leaves, but differs from it in having long pedicels from which the apparently staminate flowers have fallen. The Pires and Black collection cited below compares well with the type specimen. Brazil. MINAS GERAIS: Serra do Cip6, Schwacke 11780 (B-holotype), Pires & Black 2816 (NY). Coccoloba charitostachya Standley in A. C. Smith, Lloydia 2: 176. 1939. The type of this species is A. C. Smith 2356, collected near the mouth of the Charwair Creek, in the basin of the Rupununi River, British Guiana. The holotype is in the herbarium of the Chicago Natural History Museum. This species is not well defined in the original description and has not been recollected. Additional material is badly needed for an understanding of the species. At present the species may be characterized by the slightly rugose leaf blades which are elliptic-ovate in shape, rounded at the apex and lighter in color on the lower surface. The fruits are all insect-infested and abnormal and of no diagnostic value. Flowers are not known. Coccoloba chacoensis Standley, Field Mus. Publ. Bot. 17: 239. 1937. This species is to be referred to the synonymy of Coccoloba spinescens. Coccoloba chacoensis was based on Cardenas 2529, from Bolivia; the holotype is in the Chicago Natural History Museum. Buchinger and Sanchez (Bol. Soc. Argent. Bot. 7: 253. 1959) recognized this species and maintained it as distinct from C. spinescens Morong because of the ab- sence of lateral branches terminating in spines and the presence of "glands" on the lower leaf surface. Although the Argentine botanists undoubtedly know these species in the field, the characteristics they have chosen to separate the species are not reliable in herbarium specimens. The holotype compares favorably with such collections as Morong 882 (the type of C. spinescens) and Hassler 11476 and 2486. Coccoloba confusa Howard, nom. nov. Coccoloba declinata Martius, Beibl.

Polygonum declinatum Vellozo (Flor. Flum. 162. 1825, Icon. 4: t. 41. 1827) was described briefly and in general terms. The illustration given 224 JOURNAL OF THE ARNOLD ARBORETUM [IvL. XLI in the Icones is a poor one showing scarcely any characteristic of value in defining the taxa in Coccoloba. It was suggested by Dr. I. MI. John- ston in his library notes that Pharmacopolis, the locality given, might be near the mouth of the Rio Taquari in the western part of the state of Rio near Paraty. The transfer of the Vellozo name to Coccoloba made by Martins in an obscure paper is seldom correctly cited. Martius refers to two specimens, one from "Montem Talegraphi," in "Prov. Sebastionopolitana," and the other near Pendamonhangaba and Taubate, in Sao Paulo. Martius' brief description of Coccoloba declinata is obviously based on the specimens cited and could scarcely be drawn from either the description or the plate given by Vellozo. In 1855 when Meisner prepared the treatment of the genus for the Flora Brasiliensis, he described the species and established three new varieties: a minor, /3 Vclloziana and y major. For Coccoloba declinata var. minor, Meisner cited in reference "Coccoloba declinata Mart. Herb. propr." and a specimen from the Rio Doce collected April 1816 by Prince Maximilian. I have not seen this specimen in material from Brussels, Leningrad, Munich, or New York, the usual places for Martins and Meis- ner specimens. Meisner's variety, Velloziana, is based on the epithet and reference "Polygonum declinatum Vellozo Flor. Flum. IV. t. 41" and in place of a specimen Meisner cites "in prov. Rio de Janeiro." Neither Meisner nor more recent authors cite the specimen from "Mon- tem Talegraphi" which Martius mentioned in the original transfer of the Vellozo name. The specimen from Iendamonhangaba is referred by Meis- ner to his var. major. Meisner prepared the treatment for Coccoloba in DeCandolle's I'rodro- mus, using the same broad concept of varieties comprising the species C. declinata. In this treatment, however, the assignment of var. major to the species is questioned. In his monograph of the genus Lindau reduced to synonymy Meisner's varieties minor and Velloziana. Lindau recognized the var. major, but commented on the poor condition of the type specimen and suggested that it might be a new species. There appear to be no Vellozo collections available: thus the inter- pretation of the species must be made from the inadequate original de- scription and the rather poor drawing. In comparing the drawing with the specimens cited by Martius, Meisner and Lindau, I am convinced that these authors have misinterpreted Vellozo's species. \ellozo's drawing shows that a scrambling plant is intended, but the material cited by previous authors for Coccoloba declinata is shrubby, with geniculate branches. Again, the drawing shows a short, regular inflorescence, while the voung inflorescences of the specimens cited by earlier authors are geniculate, with the older inflorescences elongate. The most obvious match for the Vellozo species is the Martius specimen cited as the type of C. racemulosa. This is a liana with short lateral branches and comparable 1960] HOWARD, STUDIES IN THE GENUS COCCOLOBA, IX 225 inflorescences. The venation of the type of C. racemulosa compares favor- ably with that illustrated by Vellozo, while the venation of specimens cited by Martius, Meisner and Lindau does not. It appears to me that the drawing of Polygonum declinatum Vellozo most nearly compares to Coccoloba racemulosa Meisner. The material which Martius, Meisner and Lindau cited and described as Coccoloba declinata therefore requires a new name. I propose the name C. confusa, to call attention to this problem. Lindau's description (Bot. Jahrb. 13: 166. 1890) applies to the specimens cited, including those originally mentioned by Martius in transferring Vellozo's specific epithet. The inclusion of the Krukoff and the Archer collections from Amazonas and Para creates a sizeable gap in the known range of this species. On the basis of available material, these specimens must be assigned here. Brazil. AMAZONAS: Humayta near Livramento, Krukoff 6669 (NY). PARA: Belem, Archer 7830 (F, K).

Coccoloba cordata var. praecox Hassler, Repert. Nov. Sp. 14: 162. 1915. Both Meisner and Lindau have indicated the similarity of Coccoloba cordata Chamisso and C. candolleana Meisner. Lindau distinguished be- tween these in his key by placing C. candolleana in a group of species having leaves glabrous on both surfaces and C. cordata in one having leaves pubescent along the midrib and nerves on the lower surface. Lin- dau has placed the two species adjacent to one another in the text. Among the major characters of these species, Lindau described C. candolleana as having tomentose ocreae while those of C. cordata are glabrous. The type collection of Coccoloba cordata is Scllow s.n. from the Rio Pardo area of Brazil. I have seen three sheets of this collection. One in the herbarium at Berlin bears the full data given by Chamisso and is selected as the lectotype. The other two were annotated only "C. cor- data N." The descriptions given by Chamisso and Lindau are not entirely accu- JOURNAL OF THE ARNOLD ARBORETLI 'M rate. Various branches of the specimens comprising the type collection have puberulent or tomentose ocreae, although other portions are glabrous. Most of the leaves are coarsely pubescent along the midrib at the base of the leaf, but some are completely glabrous. Coccoloba candolleana was based on Blan cht IS IS. A single specimen is cited as being at Geneva while a smaller specimen from the MIeisner herbarium, now at the New York Botanical Garden, bears several of IMeisner's annotations: (1) "(. cordata Chain. ?" which he declared to be different on the basis of the shorter petiole and more coriaceous bladtes; (2) a variety of ('. cordata named for Blanchet, a name which was not published, and finally (3) "Coccoloba candolleana n." The Blanchet col- lection has broader leaves and shorter petioles, but can be compared favor- ably with portions of the Sellow collection which is the type of (. cordata. In his monograph Lindau included a collection from (olombia (Goudot 4) in the description of Coccoloba candolleana. This collection is better referred to ('. padijormis, a species known from Venezuela and Central America (Howard. Jour. Arnold Arb. 40: 210. 1959). Coccoloba cordata var. praccox Hassler was based on a specimen, Iassler 7279, from Paraguay which is staminate, in contrast to the pis- tillate type of C. cordata. The deciduous characteristic of the plant is not significant, and the variety is not worthy of recognition. Argentina. CHACtc: harranrqueras. Isl de Temores. Curran 402 (I s. FOtR- M(IsA : Coman.

No specimens are cited and, in fact, a broad general distribution is attributed to the species. Through personal correspondence I have learned from Dr. Maria Buchinger and other Argentine botanists that no Rojas collections can be attributed to this species. The species appears to be impossible to typify. Buchinger and Sanchez (Bol. Soc. Argent. Bot. 7: 255. 1959) list Cocco- loba corrientina as a questionable species, but suggest its similarity to C. morongii, the correct name of which is C. paraguariensis. I concur with this suggestion. Coccoloba crescentiifolia Chamisso, Linnaea 8: 134-136. 1833, "cres- centiacfolia." The correct name of this species is Coccoloba arborescens (Vellozo) Howard based on Polygonum arborescens Vellozo. For a discussion of the nomenclature and additional synonymy see the previous paper in this JOURNAL OF THE ARNOLD ARBORETUM series (Jour. Arnold Arb. 41: 43-45. 1960). Specimens previously re- ferred to this species are listed under C. arborescens above. Coccoloba cruegeri Lindau, Bot. Jahrb. 13: 209. 1890. Coccoloba ernstii Johnston. Proc. Am. Acad. 40: 6S5. 1905. Coccoloba oblonga Lindau, Bot. Jahrb. 13: 136. 1S90. This species was based on a Crueger collection from Trinidad. Lindau described the fruits and assigned the species to the section Campdcria. Currently available collections from Berlin and (;Gttingen are fragmentary and sterile. The specimen from the Trinidad herbarium appears to have had flowering parts at one time. There is some doubt as to what Lindau actually saw and described, for there is no evidence in the vegetative parts that the species is related to the others which he assigned to section Campderia. Coccoloba obla onga Lindau was described at the same time as ('. crucgcri and was based on Ricdcl 614, reported to be in ''herb. l'etrop." I have now seen that specimen and the others cited below, and there is no ques- tion that (. oblonga is the same as C. cruegeri. The Riedel collection from Ilheos, Bahia, represents a sizeable, but not unlikely, extention of range. As Lindau indicated, the material is for all practical purposes sterile, although the specimens do have immature and poo rly preserved inflores- cences and flowers. The range of this species is now from the islands of Trinidad and Mar- garita to British Guiana and Bahia in Brazil. Collections from Trinidad and Margarita were cited in an earlier paper (Jour.

Coccoloba cujabensis is sug- gestive of C. ruiziana Lindau. but field study or additional collections are necessary to determine their correct relationship. Hassler compared his new species, Coccoloba longiochreata, with C. alagornsis Weddell and C. floribunda Lindau. He distinguished it on the basis of the larger ocreae. The type selected by Hassler is a vigorous staminate flowering specimen. The type of C. cujabensis is a fruiting col- lection. On the basis of vegetative characteristics they are similar, and any question is resolved by a study of the Werdermann and Kuntze col- lections cited below. These show the intermediate conditions of ocreae and leaf venation between the type specimens of C. cujabensis and C. (VOL. XLI 1960] HOWARD, STUDIES IN THE GENUS COCCOLOBA, IX 229 longiochreata.

Lindau described consecutively Coccoloba cylindrostachya (based on Glaziou 13135) and C. glaziovii (based on Glaziou 8089) in his mono- graph of the genus. Both collections were made in the vicinity of Rio de Janeiro. An examination of the specimens fails to support the differences which Lindau felt would separate the two species. Therefore, C. cylindro- stachya has been referred to the synonymy of C. glaziovii. STo be continued] JOURNAL OF THE ARNOLD ARBORETUM VOL. XLI JULY 1960 NUMBER 3 STUDIES IN THE GENUS COCCOLOBA, IX.

Brazil. Lindau placed a fragment of this Martius collec- tion in the Berlin herbarium, but in his monograph he also cited Perrottet 83 from British Guiana. I have seen the latter collection and have referred it to C. lucidula. Both C. declinata and C. lu:ciula are poorly represented by herbarium material. When additional collections are available for study the relationship of these two species should be re-examined. Coccoloba declinata, as represented by the Martius collection, is not well defined. The type specimen has partially mature leaves and func- tionally staminate flowers. The distinguishing characteristic, given by both Meisner and Lindau, is the origin of the ocreolae at the apex of the pedicel. However, careful dissection proves that this is an effect of drying and that while the ocreolae are fused to the pedicels in the type specimen, they may be free in other collections. The species is similar to C. ilhecnsis, C. bractcolosa and C. glaziovii, differing in the more scandent habit, the shorter inflorescences and the smaller leaves, though this characteristic may be due to immaturity. Field studies or additional collections may clarify the relationship of these species. * Continued from volume XLI, p. 229. JOURNAL OF THE ARNOLD ARBORETUM Coccoloba densifrons Martius ex Meisner.

Jahrb. 13: 177. 1890), citing the holotype (Martius s.n., from Ega in Brazil), he did not include the species in his key to the genus. Coccoloba barbrvana is based on a Ruiz and I'avon collection from Peru, but I fail to find any reliable differences between these species, either in Lindau's descriptions or in the specimens he annotated. Coccoloba pichuana Huber was based on a I)ucke collection from Obidos, Brazil. In the original description it was compared with C. padiformis, a very similar species occurring on the north coast of South America and in Central America. At present the two species are dis- tinguished on the basis of leaf size and shape and the nature of the venation, but these differences may prove to be unreliable when both species are represented by more adequate material. For the present, therefore, the authentic material of C. pichuana is best referred to the synonymy of C. densifrons. I have indicated previously (Jour. Arnold Arb. 41: 46. 1960) that Coccoloba douradensis, published as a provisional name with a short, four- word description, is best considered as a nomen nudum. Furthermore, the collection cited by Glaziou is a mixture, parts of which are Coccoloba marginata Benth. while the remainder is more correctly assigned here. Another specimen which may be referred to (occoloba densifrons is Haenke s.n., collected in Peru on May 24. 1897, and now in the Berlin herbarium. The sheet, bearing Gross' annotation label, has been given an unpublished name referring to the city of Guayaquil. Coccoloba densifrons is similar to Coccoloba sphacroccca (C. padi- formis), the former being known only in flower and the latter in fruit. Additional collections may prove these to be the same. On the basis of the specimens I have seen, they are presently to be distinguished by the finely reticulate upper leaf surface of C. sphacrococca, in which the primary veins are scarcely evident. In C. densifrons the primary veins are arcuate and clearly evident, impressed above but sharply ridged when dry. Brazil. ACRE: Il'e 9348 (c, K).

Coccoloba dioica Karsten ex Lindau, Bot. Jahrb. 13: 170. 1890. A single fragmentary specimen in the Leningrad herbarium, to which is attached Karsten's embossed label, bears this epithet. I have previously referred this species, the type of which was collected near Caracas, Vene- zuela, to the synonymy of Coccoloba coronata Jacq. (Jour. Arnold Arb. 41: 40. 1960). Coccoloba dioica Steudel, Nomen. Bot. 390. 1841. Lindau (Bot. Jahrb. 13: 220. 1890) refers this epithet to Muhlenbcckia sagittifolia Meisner. The name is used in a list without description by Steudel, and was reported to apply to a species from Chile. I have not seen any specimens bearing this name. Coccoloba diversifolia Jacquin, Enum. Pl. 19. 1760; Hist. Stirp. Am. 114. pl. 76. 1763; Howard, Jour. Arnold Arb. 30: 421-424. 1949, 40: 195-196. 1959. Although this species is listed in several floristic treatments of South America, I have not seen correctly identified specimens from the area. Jacquin attributed the species to Hispaniola in his second treatment and I have previously cited specimens from the Greater Antilles, Antigua, Mexico, British Honduras, Guatemala and Florida. Coccoloba dugandiana A. Fernandez, Mutisia 5: 1. 1952. There is no question that this is a distinct species, but unfortunately Fernandez' description has been based on what must be considered anomalous material. Furthermore, he did not indicate that the species was dioecious, or that the flowers he described were functionally staminate. The abnormally emarginate leaves of the type are not characteristic of the species. Fernandez' statement that the immature achenes are pubescent is in error, for the fruiting perianth, not the achene, is pubescent. Additional collections by Cardona and Llewelyn Williams from the Bolivar and Amazonas regions of Venezuela represent the pistillate plants to be assigned to this species. Whether these are typical I cannot deter- mine. The leaves of these collections are comparable to the type in the thickness of the blade, the denseness of the vein reticulations and the JOURNAL OF THE ARNOLD ARBORETUM pubescence. However, all the leaves are smaller and of contrasting shapes, the blades varying in shape from ovate, obovate or oblong to obovate- elliptic, and in size from 12 X 10 or 14 X 7 to 15 X 11 cm. long and broad. The leaf base is rounded or truncate and slightly cordate. The apex is obtuse to acute or slightly apiculate. The petioles of the mature leaves are approximately 1.8 cm. long. The inflorescences of these speci- mens are at most 10 cm. long and 7 cm. wide. Individual branches of the inflorescence are densely flowered and all parts of the flower, including the rachis, are densely tomentose. The tomentum on the perianth characterizes this species. Only three fruits remain attached to the specimens and all are crushed, indicating that the perianth is fleshy. The hypanthium sur- rounding the mature achene is only slightly vascular. The mature fruit is distinctly pubescent, a most unusual condition in this genus. It is not clear how the leaf shape of this species will finally be defined. Certainly the pubescent leaves, the compact pistillate inflorescence, and the pubescent fruit clearly distinguish it at present. Additional collections of this species from the interior of Colombia and Venezuela are needed. Colombia. BOVACA: Cairo Guira near mouth of Rio Meta, Ilaught 2624 (us-isotypel. Venezuela.

Coccoloba erecta Glaziou, Bull. Soc. Bot. Fr. IV. 11(Mem. 3f): 572. 1911. This specific name must be considered a nomcn nudunm, for Glaziou's description states only. "Arbuste droit, fl. blanc jaunatre." He cited his own collection number 14220 which, unfortunately. is a mixture. Glaziou apparently mixed his field tags and numbers for the sheet of Glazion 14220 in the Paris herbarium bearing the annotation "Coccoloba erecta Glaz. n. sp." is actually C. schwarkcana, while a comparable specimen in the Berlin herbarium, Glazion 14219, is one of two specimens cited by Lindau in describing C. schwauckcana. Coccoloba ernstii Johnston. Proc. Am. Acad. 40: 685. 1905. This species has been referred to the synonymy of Coccoloba crucgeri Lindau in earlier papers (Jour. Arnold Arb. 40: 74. 1959. 41: 228. 1960). Coccoloba crrnstii was based on Johnston 2,50 (cGi) from El Valle, South Hill, Margarita Island, Venezuela. Coccoloba excelsa Bentham in Hooker. London Jour.

Although I have examined the material cited by Eyma, as well as addi- tional specimens, I cannot distinguish between Coccoloba cxcclsa and C. [VOL. XLI 1960] HOWARD. STUDIES IN THE GENUS COCCOLOBA. IX 235 micropunctata. Eyma believed that C. micropunctata could be distinguished on the basis of its narrow, tubular, membranaceous ocreolae and its non- punctulate leaves and inflorescences. The ocreolar distinction appears to be weak, varying with the age and the sex of the flowering material. In the description of C. micropunctata Eyma reported his material as "sub lente dense glanduloso(?)-punctulatae." although an examination of his material indicated broken hairs and clear or black hair bases which are comparable to structures often called punctations in C. excelsa. Coccoloba micropunctata is based on material collected from vines, but the writer's experience in the West Indies indicates that leaf shape and size, as well as texture and pubescence, varies widely in lianas. In the original description of Coccoloba parimensis, Bentham based the species on Schomburgk material from Rio Parime. He reported further that "Hostmann 245 from Surinam may possibly be a variety of the same species." Meisner (Fl. Bras. 5(1): 35. 1855) described this Hostmann collection as C. parimensis var. hostmanni. Lindau (Bot. Jahrb. 13: 170. 1891) assigned this same material to the synonymy of C. excelsa. British Guiana.

Lindau's treatment of Coccoloba excoriata (Bot. Jahrb. 13: 211-212. 1891) is confusing. Of the many specimens which he cited, the ones I have seen should be referred to C. venosa. I have not seen a Widgren specimen from Rio de Janeiro to which he referred, nor the one which Schomburgk referred to as "Fl. & Faun. Br. Guy. 821." This reference is to "Coccoloba nivea," a synonym of C. venosa which applies to a plant under cultivation. Coccoloba venosa is represented in the native flora of South America and will be discussed later. Coccoloba excoriata L., as correctly applied, is a synonym of C. tenuifolia L. (Howard, Jour. Arnold Arb. 38: 93. 1957), a native species of the Bahamas. Cuba and Jamaica, and has not been reported as either a cultivated or an indigenous plant of South America. Coccoloba fagifolia Jacq. Hort. Schonbr. 3: 55. pl. 352. 1798. Although Jacquin published an excellent plate of this species and at- tributed the plant to the vicinity of Caracas, the species has not been collected or recognized in recent years. I find Jacquin's species difficult to place. In the Meisner herbarium, now at the New York Botanical Garden, there is a packet with three detached leaves bearing the legend, "Coccoloba fagifolia Jacq. H.S. (mann tremula, verisim. ipsins Jacquini patris script.) folia speciminis sterilis Herb. Jacquini in Hb. Mus. Vindo- JOURNAL OF THE ARNOLD ARBORETUM bon." This appears to represent one of the specimens cited by Meisner in his treatment of the species for DeCandolle's Prodromus (14: 165. 1856- "v.s.c. ex Schoenbr. in herb. Jacq. patr. et fil."). These three leaves have long, thin petioles and blades of thin texture. They do not represent any species of Coccoloba known to me, and there is no evidence that they even belong to the genus. Moreover, these detached leaves do not compare favorably with the original illustration. Lindau (Bot. Jahrb. 13: 162. 1890) recognized the species and cited a specimen collected by Boos which was in the Vienna herbarium. How- ever, since the Coccoloba material in that herbarium was destroyed during World War II, the material which Lindau cited cannot be identified. Presumably the Boos specimen was a small one, for Lindau accumulated for the Berlin herbarium a large number of fragments from important species, but C. fagifolia is not represented in the material which I have on loan from that herbarium. No recent material has been assigned to Coccoloha fagifolia. so its interpretation must rest on the original illustra- tion, although a comparison of Jacquin's plate with that of C. vircns Lindley (Bot. Reg. 21: pl. 1816. 1836), which is C. coronata. shows many similarities. If Jacquin's plate may be accepted as representing an accurate description, then it seems clear that C. fagifolia should be assigned to the synonymy of C. coronata Jacq. The proper identification of the Jacquin material in the Meisner herbarium remains unsolved. Coccoloba fallax Lindau, Bot. Jahrb. 13: 172. 1890. Coccoloba caurana Standley, Publ. Field Mus. Bot. 22: 73. 1040: Llewelyn Williams. Explorac. Bot. Guayana Venez. 189. 1942. Coccoloba fallax seems to be distinguished by the fascicled inflorescence of simple racemes, the conspicuously large ocreae, especially those clustered at the apex of the stem and around the racemes, and the strongly keeled midrib. The type collection of Coccoloba caurana has immature in- florescences, but comparable mature material has been found in Trinidad. There is no question that C. caurana is the same as C. fallax. The Trinidad specimens have been cited in a previous paper, in which the species was also recognized as occurring in Venezuela (Jour. Arnold Arb. 40: 79. 1959). The type of C'. fallax is Crueger 114. The lectotype selected is the specimen in the Gottingen Herbarium. The holotype of C. caurana is Llewelyn Williams 11366 (F). Coccoloba fasciculata Meisner in Warming, Symbol. Floram Bras. 6: 128. 1870. Lindau cited this epithet and reference in the synonymy of "C. longi- pendula" in his monograph (Bot. Jahrb. 13: 177. 1890). The original publication is a report on Warming's collections from Brazil. One entry is "Coccoloba fasciculata Wedd.. Meissner in DC l.c. 166 and Mart. I.c. 27," with a citation of "Lagoa Santa: . . . Serra da Piedade legit Warm- [VOL. XLI 1960] HOWARD, STUDIES IN THE GENUS COCCOLOBA, IX 237 ing Jan.-Febr. florentem." This is obviously a misidentification and not a new entity, as Lindau implied. Lindau referred the epithet to the synonymy of C. longependula, which I cannot distinguish from the older C. sticticaulis (q.v.). Lindau also cited the Warming collections as follows: "Rio de Janeiro in silvis ad Lagoa Santa: Warming n. 129; ad radices montis Serra da Piedada: Warming n. 126." I have seen specimens of each and have referred them to C. sticticaulis Weddell. Coccoloba fasciculata Weddell, Ann. Sci. Nat. III. 13: 258. 1849. I have discussed this species in an earlier paper (Jour. Arnold Arb. 41: 44. 1960) and have referred it to the synonymy of Coccoloba arborescens (Vellozo) Howard. Coccoloba fasciculata Weddell was based on Blanchet 796 collected in Bahia Province, Brazil. The type is in Geneva. Coccoloba fastigiata Meisner, Fl. Bras. 5(1): 34. 1855. Coccoloba goudotiana Meisner. Fl. Bras. 5(1): 35. pl. 13. fig. 1. 1855, not Weddell. In the original description Meisner described the species and a variety "f3 glabrata," and cited specimens to illustrate both taxa. This is con- trary to his usual practice, in the same volume and treatment, of con- sidering the species to consist of varieties for which specimens are cited. The variety glabrata Meisner, represented by "Schott 5537 (914)" and part of Schott 5540 (in Vienna), is better assigned to Coccoloba mosenii. For the type variety of the species, Meisner cited Schott 5540, collected in Rio de Janeiro Province, Brazil, and Schomburgk 1262, in the Berlin herbarium. The latter collection was supposedly made in British Guiana. Lindau, who worked with the Berlin material around the year 1890, mentioned the Schomburgk collection under the name Coccoloba fastigiata, but attributed it to Meisner, "pr. p. ex. Meissn." I cannot determine whether Lindau actually saw this material, but I suspect that he did not, for in his citation of specimens seen (Bot. Jahrb. 13: 224. 1890) he listed Schomburgk 1262 as C. marginata. I have on loan the Coccoloba material from the Berlin herbarium and I fail to find the Schomburgk collection represented. I suspect that Meisner was in error in including the Schom- burgk specimen and that C. fastigiata should be typified only by Schott 5540. Meisner stated that the specimen he saw was in the Vienna herba- rium. Unfortunately, the Coccoloba material in this herbarium was destroyed during World War II. A photograph and a fragment of the holotype is at the Chicago Natural History Museum, and a more complete specimen is in Brussels. Therefore it seems wise to designate the specimen at Brussels as the lectotype. Coccoloba goudotiana Weddell was based on a Goudot specimen col- lected near San Luis, Colombia, and now in the Paris herbarium. Meisner elaborated on the original description and illustrated the species. In addi- tion to the Goudot specimen, Meisner also cited a collection by Pohl in JOURNAL OF THE ARNOLD ARBORETUM the Zuccarini herbarium at Munich. I have seen both of these specimens and it seems clear that the illustration in Flora Brasiliensis was made by combining features present in both specimens. Coccoloba goudotiana Weddell is C. obovata, while C. goudotiana as described and illustrated by Meisner is C. fastigiata. Brazil. Rio DE JANEIRO: Aguacu. Schott 5540 (BR-lectotype.

Without locality: Pohl s.n., in Herb. Zuccarini as cited by Meisner (i ). Coccoloba fastigiata var. glabrata Meisner, Fl. Bras. 5(1): 34. 1855. Meisner cited "Schott 5537 (914)" and, in part, Schott 5540 as repre- sentatives of his new variety with specimens in the Vienna herbarium. Lindau recognized the variety (Bot. Jahrb. 13: 172. 1890), citing Schott 5537 and Pohl 914 with specimens at Vienna and Berlin. The Vienna material has been destroyed and material from these collections is not included in the specimens of Coccoloba from the Berlin herbarium. A photograph of Schott 5540 and a fragment of this specimen from Vienna are preserved in the herbarium of the Chicago Natural History Museum and clearly identify the specimen as C. jastigiata. It appears that the fragment of Schott 5537 (F), all that remains of the collection, should be referred to C. moscnii Lindau (q.v.). Coccoloba ferruginea Endlicher, Catalogus Hort. Acad. Vind. 1: 274. 1842; Ettingshausen, Blattskel. d. Apetalen 91. pl. 26. fig. 2. 1858. Lindau referred this epithet to the synonymy of his (occoloba excoriata (q.v.). Endlicher cited the name without description as a plant which had been obtained from the Berlin botanic gardens and was cultivated in Vienna gardens. Ettingshausen illustrated a leaf skeleton, using the name Coccoloba ferruginea. He acknowledged that his material was from a cultivated specimen, but did not discuss the illustration or the species. The leaf skeleton is inadequate for positive identification, although it is probably C. vcnosa L.: none of the specimens I have seen hears the name C. Jcrruginca. Coccoloba filipes Standley, Trop. Woods 40: 14-15. 1934. In the original description Standley wrote, "the distinctive characters of the species are the greatly elongate, many-flowered, lax racemes, with flowers on conspicuously long and slender pedicels." The type. Dugand 380, was collected in flower at Santa Rosa. west of Barranquilla, Colombia, on March 13, 1933. The flowers, although borne singly at each nodule on the inflorescence axis, are apparently functionally staminate, producing pollen grains. The specimen, now at the U.S. National Herbarium, bears two terminal, thin-textured, darkened leaves, suggesting that the plant is deciduous. The leaves arise from above the base of the ocreae. VOL. XLI 1960] HOWARD, STUDIES IN THE GENUS COCCOLOBA, IX No additional material which can be referred to this species has been seen. It appears to be distinct among the Colombian species of the genus and, on the basis of the material available for study, is not closely related to or even similar to any other South American species thus far described. Although several species from Cuba or Puerto Rico have similar long pedicels, none are so tenuous. Coccoloba firma Martius ex Colla, Herb. Pedem. 5: 48. 1836; Eyma, Meded. Bot. Mus. Utrecht 4: 3. 1932. The original description, while brief, is explicit and clearly intended to be that of a new species. In a list of species Colla attributed the name to Martius. No more definite location than Brazil was given. Eyma also used the name attributed to Martius in comparing it with his proposed new species, Coccoloba micropunctata. Eyma cited specimens at Kew and the Natal Herbarium, Durban, which he said were listed under the name Coccoloba populifolia Weddell. The correct name for the latter species is C. alnifolia Casaretto. Eyma apparently recognized both C. firma and "C. populifolia." I have not seen the specimen from the Natal Herbarium, South Africa, nor have I been able to locate a specimen so named at Kew. There is a Martius sheet at the British Museum bearing the name C. firma, which I believe is properly C. alnifolia. No material of C. firma was found in the collections of Martius which I have on loan from Munich, Brussels and Leningrad. I am therefore reluctant to accept this unsupported name until the material which Colla saw, or at least that which Eyma cited, has been located. If this should prove to be the same as C. alnifolia Casaretto (1844), as I suspect, the older C. firma Martius ex Colla should be accepted as the correct name. Coccoloba gardneri Meisner, Fl. Bras. 5(1): 36. pl. 15. 1855; Howard, Jour. Arnold Arb. 41: 44. 1960. This species is based on Gardner 600 from Serra dos Orgaos, Brazil. In the original description, which is clearly based on the Gardner collec- tion, Meisner cited Polygonum frutescens Vellozo in synonymy and also Coccoloba vellosiana Casaretto, the latter with some doubt. I have pre- viously considered the identity of species described by Vellozo and Casa- retto and have also concluded that C. gardneri Meisner represents still a third species. Meisner's species was placed in the synonymy of C. crescentiifolia by Lindau, but clearly it is not the same as C. arborescens (Vell.) Howard, loc. cit. I cannot adequately define the species on the basis of the single collection available and wish to call this problem to the attention of future collectors who may visit the area of Rio de Janeiro. Coccoloba glaziovii Lindau, Bot. Jahrb. 13: 163. 1890. Coccoloba cylindrostachya Lindau, Bot. Jahrb. 13: 163. 1890. 239 JOURNAL OF THE ARNOLD ARBORETUM Coccoloba sublobata Heimerl, Denkschr. Akad. Wien. Math.-Nat. Klasse 79: 244. 1908. Glaziou 8089 is the only collection cited by Lindau in the original description. Of the specimens cited from four herbaria, I have designated that at Berlin as the lectotype. I am unable to distinguish between Coccoloba glaziovii and C. cylin- drostachya which Lindau based on Glaziou 8089 and 13135 respectively. Lindau distinguished between them by placing C. glaziovii in a group of species with the rachis glabrous and C. cylindrostachya in a contrasting group having the "rachis vario modo pilis instructa." His species descrip- tions amplify this supposed difference and suggest others, e.g.. the position of the petiole in relation to the base of the ocrea, which, however, is not borne out in a re-examination of the type specimens cited. I have seen all of the specimens which Lindau cited from both collections and can only conclude that one species is represented. Glaziou 3087 was annotated by Lindau as a possible new species. It is a vigorous shoot, probably adventitious in nature, with longer internodes, larger leaf blades and more pubescent parts. Lindau never published the name written on the sheet. I believe the specimen should be included in Coccoloba glaziovii. Another unpublished name honoring Lindau is found on the collection Schwacke 13673 with the author given as Schwacke. Although the specimens seen have more delicate branches, more tenuous and pendant inflorescences and more oblong leaves, I feel that this mate- rial is properly assigned to C. glaziovii. The Chicago Natural History Museum has a photograph of the holo- type of Coccoloba sublobata which was in the herbarium at Vienna. The type was lost during World War II and the only duplicate of this collection which I have seen is in the Berlin Herbarium. This Berlin specimen bears an unpublished name, attributed to Heimerl and referring to the subundu- late leaves, which is more appropriate than the one actually published. Although the type of C. glaziovii is a staminate plant, there is no question that Wacket's collection represents the same species in fruit. Heimerl's original description does not refer to the type collection by number. The number 12 cited below is legible in the photograph of the type and on the isotype. In his monographic treatment of Coccoloba striata (Bot. Jahrb. 13: 164- 165. 1890), Lindau cited numerous specimens from the Brazilian states of Bahia, S1ao Paulo, Rio and Pernambuco. 1 have seen only one of these, Mosen 3664, which I believe to be more properly associated with C. glaziovii. Coccoloba striata, based on a Schomburgk collection from the Roraima area, appears to be a northern species. The remainder of the collections cited by Lindau should be examined for their correct relation- ship here. Brazil. MINAS GERAES: Itabira do Matto Ventro, Schwacke 13673 (B, P). PARANA: Volta Grande.

This species is based on Goudot s.n. from San Luis, Colombia. The type specimen is in the Paris herbarium and the species is clearly synony- mous with Coccoloba obovata HBK. (1817). Coccoloba goudotiana Weddell sensu Meisner, Fl. Bras. 5(1): 35. pl. 13. fig. 1. 1855. In the original publication Meisner did not intend to describe a new species, but only to list the Weddell species. However, he cited the Goudot material used by Weddell, as well as a Pohl collection from the Zuccarini herbarium which is not the same species. Meisner's description and illustration combined features of both plants. I have seen the Pohl specimen, now in the Munich herbarium, and refer Meisner's interpreta- tion of Coccoloba goudotiana to the synonymy of C. fastigiata Meisner. Campderia gracilis Meisner, Fl. Bras. 5(1) : 23. pl. 6. 1855; DC. Prodr. 14: 170. 1856. Meisner described and illustrated this species in 1855. He cited a Spruce collection without giving a collector's number from around Barra in the "Prov. Rio Negro." The following year in the Prodromus he cited Spruce 958, reporting specimens to be in the DeCandolle Herbarium and the Herbarium Monacense (Munich). The illustration in Flora Brasiliensis appears to be a compilation of the two specimens. The original pencil sketch of the illustration of flowers and fruits is attached to the sheet at Munich and this sheet should be designated as the lectotype. However, I cannot determine the source of the fruiting material which Meisner illustrated, since comparable achenes do not appear on either sheet at the present time. Lindau referred Campderia gracilis to the synonymy of Coccoloba ovata Bentham. This appears to be the correct specific place- ment on the basis of the material I have examined, but there is a question as to whether C. ovata belongs in the genus Coccoloba. This matter will be discussed further under C. ovata. I have seen specimens of Spruce 958 from Munich (lectotype), Berlin, Geneva, the Gray Herbarium, Leningrad and Paris. Coccoloba gracilis HBK. Nov. Gen. 2: 176. 1818. Two specimens, one in the Willdenow Herbarium and one at Paris, can be considered to be authentic for this species. Both are relatively small and are characterized by slender, nearly geniculate inflorescences of func- tionally staminate flowers. The original description has information appli- cable to labels on both specimens but does not exactly match either. It J(OURNAL OF THE ARNOLD ARBORETUM appears desirable to consider the Paris specimen as the lectotype since the only label on this sheet bears the number 3498 of Humboldt and the geographic location Rio Cachivacu given at the time of publication. These two specimens are inadequate for accurate determination as to genus. The floral structure and that of the ocreolae and the bracts appear to bridge the few weak characteristics used to distinguish Coccoloba and Ruprchtia in staminate flowering condition. With the material available, the only possible course to follow is that taken by the previous authors and monographer who placed the species in Coccoloba. Additional material is needed to determine its correct position. Macbride (Publ. Field Mus. Bot. 13: 460. 1937) assigned a fruiting collection. Wcbcrbaucr 6982, to this species in his treatment for the Flora of Peru. The Weberbauer collection bears no data regarding the plant or the place of collection beyond "Peru." The old inflorescence axes are 4-8 cm. long and are erect. The fruiting peduncles are 2-2.5 mm. long. Fruits, one of which retains the fruiting calyx, are preserved in a packet. The perianth lobes are free nearly to the base in the fruit. The achene is only slightly triangular in outline, dark brown and shiny. This specimen is clearly a Coccoloba, though not necessarily the same as the authentic material of C. gracilis HBK. Peru. Rio Cachiyacu, Humboldt 3498 (p-lectotype; without number or loca- tion fHerb. Willd. 77011). Coccoloba grandiflora Lindau, Bot. Jahrb. 13: 175. 1890. Lindau cited two collections in the original description, Glaziou 14217 and Micrs 4657. The former should be selected as the type collection and the specimen at Copenhagen designated as the lectotype. This is the only sheet among those cited below on which the label states. "Coccoloba grandiflora Lindau n. sp." Lindau's work was based upon the material in the Berlin herbarium - the fragment of a branch together with one inflorescence having one detached and two attached leaves. I have not located the Miers collection. Superficially, this species resembles Coccoloba ctnuiflora Lindau which is based on cultivated material of unknown origin. The type of C. tenui- flora was from a greenhouse plant, while C. grandiflora is from native material. I cannot determine whether cultivation (and, specifically. green- house conditions) could create the differences seen in these specimens. Coccoloba grandiflora has more conspicuous ocreolae which are membra- naceous, split longitudinally and flaring. In all other characteristics the species are similar. Both species are known only from flowering material. Brazil. MINAS GERAES: Glaziou 20439 (13, LE, NY). Rio DE JANEIRO): NuOVO Freiburg, ;laziou 14217 (C-lectotype. 1, K. LE, U ). Coccoloba grandis Bentham in Hooker. London Jour. Bot. 4: 624. 1845. This species is based on Schomburgk '25 collected on the Rio Branco, [VOL. XLI 1960] HOWARD, STUDIES IN THE GENUS COCCOLOBA, IX 243 British Guiana. Lindau placed the species in the synonymy of Coccoloba latifolia Lam. After having examined the type in the British Museum, I agree with this placement. Coccoloba guaranitica Hassler, Repert. Sp. Nov. 14: 161. 1915. Coccoloba guaranitica var. opaca Hassler, ibid. 162. Hassler compared his new species with Coccoloba schomburgkii, but on the basis of the few specimens I have seen, it seems more nearly comparable to C. padiformis from Venezuela, although the leaves of C. guaranitica are smaller and more rounded at either end. The fruits of both species are known only from immature specimens, but in both the perianth lobes are conspicuous, imbricate and appear to surround only the upper half of the achene. Hassler did not select a type in the original description in which he mentioned two collections, Fiebrig 1429 and 1440. I have not seen the latter, but the former is a shoot of vigorous and rapid growth. The variety which Hassler described differs from the species in having smaller leaves, the margins of which are undulate-crenate. It also has a shorter inflorescence. The type of the variety, Fiebrig 4305, is a mature shoot system with many lateral flowering branches. It seems quite ap- parent that the specific name has been applied to younger and more vigorous specimens and that of the variety to the more mature branching specimens and thus the variety is not worthy of recognition. A specimen of Fiebrig 4305, the type of C. guaranitica var. opaca, was studied by Gross and annotated with both a specific name honoring Fiebrig and a varietal name referring to the crisp leaf margin. Neither name has been published, to my knowledge, although Gross published other epithets in the genus in small notes, often in obscure publications. Paraguay.

Rojas 13708 (BR, P, w). Coccoloba guianensis Meisner, Linnaea 21: 264. 1848. Several specimens were cited in the original description, but no type was selected. The specimens are obviously the same as the slightly anom- alous material described earlier by Bentham as Coccoloba marginata. The variation in material called C. guianensis and the nomenclature of the complex has been discussed in other papers (Howard, Jour. Arnold Arb. 40: 84, 85. 1959; 41: 45, 46. 1960). Coccoloba gymnorrhachis Sandwith, Kew Bull. 1932: 221. 1932; Eyma, Polygonaceae, Guttiferae & Lecythidaceae of Surinam, 111. 1932. Sandwith based the original description of this species on a flowering JOURNAL OF THE ARNOLD ARBORETUM specimen. Sandwith 168, from British Guiana. The plant was described as a "bush-rope" and the type shows strong characteristics of a liana. The leaves, broadest above the middle and narrowed to the base, are rigidly coriaceous with the arcuate venation impressed above. The flowers are borne in clusters with tightly appressed ocreolae. Eyma supplemented the original description with a fruiting specimen from Surinam. The Richard collection cited below is also in fruit and is the same as the material which Evma cited, but these two fruiting collections are not good matches for the type collection and may not belong here. The fruits are warty, as though insect-infested, but no evidence of insect larvae could be found. Additional collections are needed before the morphological characteristics of Coccoloba gymnorrhachis are fully understood and the species clearly defined. British Guiana.

This is a poorly defined species requiring both field study and many more collections for an accurate interpretation. This species is similar to Coccoloba glaziovii, C. ochrcolata and C. confusa. While collections representing the type of each of these species can be distinguished on sight, I cannot find any reliable morphological characteristics useful in separating them in a key. Brazil.

Bras. 5(1): 25. 1855.1 This species is based on a Martius specimen from Ega in the Rio Negro of Brazil. Authentic material is in the Munich herbarium and is repre- sented in the collections of the Gray Herbarium by a photograph. The photograph is a montage of two herbarium sheets and two labels. One label has the hand-written annotations, "Coccoloba acuminata" and "Cocco- loba japurana" and on the same sheet is the annotation, "Alsodeia japu- rana Radlk." One of the sheets has specimens with immature inflorescences. This almost completely overlaps the other sheet from which an infructes- cence protrudes. The fruit on this axis is clearly not that of a Coccoloba. The name Alsodcia japurana Radlk. (Sitz-ber. Math.-Phys. Klasse Akad. Miunchen 20: 182. 1891) is recorded in the first supplement of Index Kewensis as an observation. There is no reference to the name Coccoloba japurana Meisner in the article cited. However, Lindau at- Rinorea japurana (Meisner) Howard, comb. nov. Basionym: Coccoloba japurana Meisner in Martius, Fl. Bras. 5(1): 25. 1855. I VOL. XLI 1960] HOWARD. STUDIES IN THE GENUS COCCOLOBA, IX 245 tributed the transfer to Radlkofer in a list of excluded species and in a footnote in his monograph i.e., "C. japurana MEISSN. = Alsodeia japurana RADLK." (Bot. Jahrb. 13: 220. 1890). Alsodeia is a genus of the Violaceae for which most modern writers use the name Rinorea. Blake, who monographed the American species of Rinorea (Contr. U. S. Natl. Herb. 20: 317. 1924), listed Alsodeia japu- rana as a "doubtful species" with the comment, "This was described from specimens with very young flowers. It is said by Radlkofer to be allied to A. racemosa." So many aspects of this misplaced epithet have been overlooked that I have made the new combination in Rinorea primarily to place the name in indices for the aid of future workers. An adequate interpretation of the photograph is impossible. Meisner's original descrip- tion could well be a Coccoloba; Lindau saw the material now in the Munich herbarium and would surely have recognized a Coccoloba as to genus; Radlkofer worked on Alsodeia and would certainly have recognized that genus; Blake did not accept the species, but it is not clear what material he saw or to which description he referred. The fruit in a photo- graph of a properly labelled specimen, supposedly the type, is not a Coccoloba, but appears to be a Rinorea. The writer cannot solve the puzzle and may not have placed the specific epithet in its proper niche. Coccoloba laevis Casaretto, Nov. Stirp. Bras. 71. 1844; Lindau, Bot. Jahrb. 13: 186. fig. 40. 1890. Coccoloba cordifolia Meisner, Fl. Bras. 5(1): 37. 1855. Casaretto did not cite a specimen in the original description, but in the same publication he described other species based on his own collections. One sheet, Casaretto 2264, in the Turino herbarium, fits the description of Coccoloba laevis in all details and should be considered the holotype. I assume that Casaretto unintentionally omitted the citation of a specimen. In the original description of Coccoloba cordifolia, Meisner cited several specimens without selecting a type. He indicated the affinities of his new species with C. nivea, C. cordata, and C. candolleana and cited in synonymy "Coccoloba uvifera Salzmann Mss. in Herb. (non Linn.)." In his treat- ment for the Prodromus (14: 155. 1856) he cited the same specimens, but he did not repeat the suggested synonymy or the possible relation- ship. Instead he placed his species next to C. laevis, which he suggested might be identical with C. cordifolia or C. candolleana. Lindau was the first to place C. cordifolia Meisner in the synonymy of C. laevis Casaretto, a decision with which I agree. The Salzmann collection from Bahia which Meisner cited is represented in several herbaria and the collection at Kew shows the full range of variation from the small-leaved type of Casaretto's species to the broader and more cordate leaved types found in Blanchet 3528. Lindau described and illustrated the fruit of Coccoloba laevis, but although I have seen most of the material he cited, I have not found a fruiting specimen, or even a single fruit, among them. If the figure pub- JOURNAL OF THE ARNOLD ARBORETUM lished by Lindau can be trusted, the possibility of a hybrid origin of this species should be examined. Coccoloba marginata or C. uvifera would seem quite likely as parents. At present C. laevis is an extremely variable species which is not clearly delineated. Brazil. BAHIA: Amaralina, San Salvador.

Coccoloba lanceolata Lindau ex (laziou, Bull. Soc. Bot. Fr. IV. 11 (Mem. 3f) : 573. 1911, nomen nudum. The collection Glaziou 19764 was cited by the author in the original publication with the brief description, "liane. f1. blanchatres, fruit noir." The specimens seen are obviously from climbing plants. The leaves and infructescence are borne on short lateral shoots. While the epithet has no acceptable standing at the present time. I do not wish either to describe the plant more fully or to place the name in synonymy until further material from southern Brazil is available for study. It is probable that this collection should be assigned to C. salicifolia. The leaves of the Glaziou specimen, however, are more lanceolate-oblong in shape, less acu- minate at the apex and thicker in texture. The fruits match the illustra- tion given by Lindau for C. salicifolia. Brazil. MINAS GERAES: Riacho das Varas, Glaziou 19764 I B. c, K). Coccoloba latifolia Lamarck, Dict. Encycl. 6: 61. ill. 316, f. 4. 1804. Coccoloba grandis Bentham in Hooker, London Jour. Bot. 4: 624. 1845. Lamarck described this species from material cultivated in the Jardin des Plantes, Paris. I have not seen authentic material, but his illustra- tion is of a single detached leaf which does not represent well the species as currently accepted. The description, although somewhat vague, seems applicable, but, since Coccoloba latijolia is similar to C. mollis, comparable field observations would be helpful. It differs in an almost complete lack of puberulence. in its much stouter and generally hollow stems and in having strongly bullate leaves. I have seen C. latifolia in Trinidad where it is a characteristic plant of savanna areas. Its habit is distinctive and this, together with the presence of many biting ants in the large ocreae. makes it long remembered by collectors. Coccoloba grandis Bentham is based on Schomburgk 825. Lindau placed the species in the synonymy of C. latifolia, where it clearly belongs. Lindau referred three collections by Burchell from Sio Paulo and Para to this species. I have seen one sterile sheet of Burchell 3982 in the her- barium at Kew and feel that this sheet, at least, should be considered the adventitious leaf form of Coccoloba warmingii Meisner. I VOL.

This remains a troublesome name which I cannot place satisfactorily. Meisner recognized the species (DC. Prodr. 14: 165. 1856), noting that the type locality was Caracas, Venezuela, and he cited one specimen (7699) in the Willdenow herbarium. This specimen consists of two sterile shoots obtained from a plant cultivated in a botanic garden and certainly is not the Jacquin type. It is properly referred to Coccoloba diversifolia Jacq. In his monograph (Bot. Jahrb. 13: 158. 1890) Lindau also accepted Jacquin's name and cited two specimens (without known collectors and from Caracas, Venezuela) to be found in the Delessert and Vienna her- baria. Lindau cited many additional collections from Florida, the Ba- hamas, Cuba, Hispaniola, Puerto Rico and the Virgin Islands. A specimen in the Prodromus herbarium at Geneva which Lindau saw, and the one I believe he cited, was probably collected by Bertero in Hispaniola. The Antillean and Florida material cited by Lindau has been referred to Coccoloba diversifolia Jacq. Although I have suggested that Coccoloba laurifolia Jacq. and C. diversifolia Jacq. may be the same (Jour. Arnold Arb. 40: 195-196. 1959), I am not entirely convinced of it. A re-examination of all material available to me from Venezuela has failed to reveal any plants which can be compared satisfactorily with the description and illustration supplied by Jacquin. The closest comparison in Venezuela would be with C. padi- formis Meisner based on the collection Moritz 377 from Caracas. Material from Central America which I have cited for C. padijormis (loc. cit. 210- 211) and additional collections to be cited in this study are not exactly comparable to Jacquin's description and illustration. These differences at present are primarily in the venation as related to the texture of the leaf blade and in the shape of the leaf apex. A field study of Coccoloba plants in the vicinity of Caracas will be necessary to determine what species Jacquin had as a basis for his description and illustration of C. laurifolia. Coccoloba laxiflora Lindau, Bot. Jahrb. 13: 191. 1890. The holotype in the Berlin herbarium is Glaziou 11444 from Rio de JOURNAL OF THE ARNOLD ARBORETUM Janeiro, Brazil.

This species has been discussed in an earlier paper in which its range was extended to Central America and additional species from that area placed in its synonymy. The selection of a lectotype was also discussed at that time. Another similar species is Coccoloba lepidota A. C. Smith (q.v.). Additional material may show that this, too, should be placed in synonymy here. Two collections from Peru, Tessman 3896 and 5258 from Iquitos along the Amazon have been tentatively referred to this species. Several herbarium specimens have been seen of a collection made in 1871 from a cultivated plant in the Calcutta Botanic Garden. No collector or data are given on the sheets, which have carried the name "Coccoloba excoriata." These are clearly to be referred to the present species. Colombia. ANTIOQUIA: Villa Arteaga.

This species was distinguished by Smith by the "characteristic scales of the petioles and young stem parts." Smith compared Coccoloba lepidota with C. ovata. which is clearly distinct. The separation of C. lepidota and C. lehmannii is more difficult and additional material may show that C. lepidota should be another synonym of that species. The lectotype of C. lehmannii. Lehmann 7560 (B), has shorter, more elliptic leaves and a predominance of simple pubescence. Coccoloba lepidota, as represented by the type collection, Krukoff 5660, has larger obovate-oblong leaves, broadest above the middle and tapering to an obtuse or truncate base. The young stems, petioles and ocreae are covered with lepidote scales and bear lesser amounts of simple hairs and resinous excretions. A tend- ency towards this development is found in the type collection of C. lehmannii and in the other collections cited below. It is probable that C. lepidota is an extreme variation of C. lehmannii. Brazil. ACRE: Near mouth of Rio Macauhan. Krukoff 5660 (NY-holotype, A, LE, M, W), 5659 (A, LE. M, NY). Coccoloba leptostachya Bentham, Bot. Sulph. 59. 1856; Meisner, DC. Prodr. 14: 163. 1856. As has been pointed out in an earlier paper in this series (Jour. Arnold VOL. XLI 1960] HOWARD, STUDIES IN THE GENUS COCCOLOBA, IX 249 Arb. 40: 188. 1959), Bentham described this species, citing the type locality as "Libertad in Colombia." The type is a Barclay specimen at Kew. I have studied this and have concluded that the specimen was collected in Central America. Recent collections from Libertad in El Salvador proved to match the Barclay collection well. I have seen no comparable material from Colombia. Coccoloba leptostachya Bentham is referred to the synonymy of C. barbadensis Jacquin (1760), which is known from Mexico, Guatemala and El Salvador. The species need no longer be considered in the South American flora. Coccoloba longependula Martius ex Meisner, Fl. Bras. 5(1): 27. pl. 9. 1855; Lindau, Bot. Jahrb. 13: 177. 1890. After an examination of the type of this species (Martius 759 from Minas Geraes, Brazil IM ), this has been referred to the synonymy of Coccoloba sticticaulis Weddell (q.v.). Coccoloba longiochreata Hassler, Repert. Sp. Nov. 14: 162. 1915. This species is clearly the same as Coccoloba cujabensis (q.v.) and has been referred to synonymy there. Hassler cited two collections, Fiebrig 1284 and 1443, in his own herbarium. The collections were made in the Gran Chaco at Puerto Talavera, Paraguay. Coccoloba longipes S. Moore, Trans. Linn. Soc.

In the original description Moore compared his new species with Cocco- loba laxiflora Lindau, which I now regard as the same as C. ramosissima Weddell. There is a striking similarity between these two species in the delicate inflorescences and the long peduncles. There are differences in the leaf size which should be re-examined when additional materials be- come available from southern Brazil. At present I distinguish C. longi- pes by the ovate-oblong leaf blades which taper from the middle to a blunt apex. Coccolobis padifolia Rusby was described without any comparison of other species. A study of the type collection indicates that it should be placed in the synonymy of C. longipes. Bolivia. Rurrenabaque, Rusby, Mulford Ex. No. 848 (NY-holotype of C. padifolia, GH). Brazil.

The two species treated here fall into widely separated portions of Lindau's monographic treatment of Coccoloba, yet it seems clear to the writer that they are identical. Coccoloba lucidula was based on flowering JO)LRNAL OF THE ARNOLD ARBORETUM specimens with delicate, membranaceous, immature leaves which crinkled in drying, turned black and became lustrous on the upper surface. Ben- tham cited only one specimen collected by Schomburgk. "2nd Coll. 947 (1262)." The species has not been collected again and no modern col- lections have been assigned to it. The mature foliage and fruiting speci- mens of C. sauiotii would appear to belong in synonymv here, but since at present there is no comparable material for C. lucidula. there is need for additional mature specimens of the latter. Coccoloba lucidula is described as a woody vine by collectors of the specimens cited below. P'rrrottct 1S'20 (P) is a delicate vine tapering to a tenuous apex. On this specimen the immature condition of the leaves is clearly shown, from minute to fully expanded, though membranaceous, forms. Many of the mature leaves of other collections are :olded, indi- cating that when fresh the midrib is sharply curved downward. The fruit is distinctive, being nearly spherical and smooth. A small stalk is dis- tinguishable at the base of the fruit and the apex is more or less obtuse, with very small, imbricate perianth lobes. P'Trrottet 83 from British Guiana which is referred here was cited by Lindau (loc. cit. 168) as Coccoloba racemulosa and, thus identified, was an im)portant example of his Guiana- northern Brazil distribution (loc. cit. 116). Coccol/oba saiotfii was described by Lindau and was based on an unnum- bered Sagot collection from "(Guana gallica" near (avenne. This is a fully matured branch of scrambling halit. The infructescence is old but fruits have beern preserved. The leaves are coriaceous and shiny above. Lindau distinguished this species from C. lucidula by the glabrous branchlets and infructescence rachis, but close examination shows that in all reliable characteristics the type collections are similar. The pubescence present on material of ('. s<,otii was overlooked 1b Lindau. Lindau also referred to specimens in the herbaria at Berlin and Stockholm, but both of these are merely fragments.
