PROCEEDINGS OF THE CALIFORNIA ACADEMY OF SCIENCES Fourth Series Vol. XVIII, No. 14, pp. 393-484, plates 33, 34 September 6, 1929 XIV STUDIES IN THE FLORA OF LOWER CALIFORNIA AND ADJACENT ISLANDS BY ALICE EASTWOOD Curator, Department of Botany Introduction In the spring of 1925, the California Academy of Sciences sent an expedition to the Revillagigedo Islands off the Pacific coast of Mexico. The U. S. Navy Department detailed the U. S. mine-sweeper Ortolan for the use of the Academy. Mr. H. L. Mason accompanied the expedition as botanist. On the way to the islands a short stop was made at Guadalupe Island and a small collection of plants was secured. Clarion Island was reached April 26, and from then until May 11, Clarion, Socorro and San Benedicto islands were explored. On the return trip, the vessel stopped at the Tres Marias Islands, May 14-24, and collections were made on Maria Madre, Maria Magdalena and Isabella islands. From there the vessel sailed north along the west coast of Lower California and made landings at Cape San Lucas, Magdalena Bay, Turtle Bay, Cedros Island, San Ouintin Bay, and San Martin Island. Mr. Mason is preparing the report on the Botany of the Revil- lagigedo Islands, but it is not yet ready. The present writer has worked up all the other collections except that from the Tres Marias Islands. The collection on these islands was made at the end of the dry season and the specimens were very poor. Duplicates were sent to Paul C. Standley, an authority September 6, 1929 394 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. on Mexican plants at the National Herbarium, and were named by him. The reports on Guadalupe Island, Cedros Island and Tres Marias Islands include all the species that have been reported from those islands, with the names of the collectors and refer- ences to the publications. This assembling of all the known species that have been published from those islands will be a great help to future explorers. Many species were originally described from certain of the localities where landings were made by the Ortolan Expedi- tion and topotypes were collected whenever possible. Lists of the topotypes have been added, supplementing those repre- sented in the collections. List of the Plants Recorded from Guadalupe Island, Mexico Guadalupe Island lies 135 miles from the coast of Lower California and 250 miles south of the border of the United States. It is about 20 miles long from north to south and 3 to 7 miles wide. From a narrow beach the island rises abruptly to a sort of plateau indented by precipitous canons and at the top traversed by ridges, the highest rising on Mount Augusta to an elevation of about 4000 feet. The northern part of the island is less arid than the southern, due to the heavy fogs which are so dense that the moisture condensing on the trees forms small streams from which some of the springs are sup- posed to be fed. Groves of pines and cypresses are on the uplands and on the sides of some of the canons at the northern end evergreen oaks are found. Palms grow in warm canons that are sheltered from the winds. This island has been known to navigators since early times and was noted by Vancouver, though he did not stop there. Goats were introduced long ago to furnish fresh meat to passing vessels. Later the island was purchased by a Cali- fornian company and was stocked with angora goats. These have multiplied excessively and have almost completely de- stroyed the vegetation so that today but little remains of one of the most remarkable floras on the Pacific coast. The first knowledge of this flora came from the collection of Dr. Edward Palmer, who spent from February to May, Vol. XVIII] EASTWOOD— FLORA OF LOWER CALIFORNIA 395 1874, exploring and collecting. The results were published by Sereno Watson, who wrote the first account of the island, in- cluding a list of the collection with Dr. Palmer's notes, in the eleventh volume of the Proceedings of the American Acad- emy, pages 105-121. One hundred and nineteen species were listed, representing 99 phanerogams, 6 ferns, 11 mosses and 4 hepatics, of which 42 phanerogams and 1 hepatic have been described as new. Dr. Edward Palmer brought back seeds of the cypress and palm. Today fine trees of the cypress are to be found in vari- ous parts of California, notably a row along the State Capitol building at Sacramento and others in Golden Gate Park. The palms are found in various parts of the state. Dr. Edward L. Greene spent a week on the island, late in April, 1885, and collected 120 species, adding 15, of which 10 were described as new, the other 5 being introduced species of wide distribution. The results of his trip were published in the Bulletin of the California Academy of Sciences, volume 1:214-228. Besides an interesting account of the island, he published the new species and the list in the same volume. Dr. Palmer made a second trip, from March 27 to April 3, 1889, and collected 72 species, adding 14, of which 4 were new. This list was published by Dr. George Vasey and Dr. J. N. Rose in their first volume of the Contributions of the U. S. National Herbarium, pages 21-27, 1890. Dr. F. Franceschi^ spent the latter part of December, 1892, and the early part of January, 1893, on the island. Besides an account of the island, which was published together with the list of species in the fourth volume of Zoe, pages 130-139, 1893, he wrote articles for several garden magazines. The phanerogams were named by Mrs. Katherine Brandegee and the lichens by Dr. E. L. Greene. Among his collections were 11 endemic species and one which Dr. Greene described as a new genus founded on a specimen in the Herbarium of the California Academy of Sciences, which he named Petromecon frutescens Pitt., 5 : 294, 1905. The other species, Petromecon palmeri, I.e., 296, was originally described as Eschscholtzia pdmeri Rose, Contr. U. S. Nat. Herb., 1 :23. 1890. *This was the name under which he published. His true name is Dr. Eroanuele Orazio Fenzi. 396 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. In the fifth volume of Zoe is an account of the Voyage of the Wahlberg, a vessel owned and used by A. W. Anthony in exploring the islands and coast of Lower California. Mr. T. S. Brandegee accompanied the expedition as far south as San Jose del Cabo, and among the places visited in the early spring of 1897 was Guadalupe Island. No full list of species was published, but 10 species were added, all from the main- land of California. In June of the same year an expedition consisting of Messrs. Rufus L. Green, Charles B. Wing and Wilbur W. Thoburn visited the island to make certain fur- seal investigations. They collected some plants, a list of which was published by Dr. William Russel Dudley in *'The Fur- Seals and Fur-Seal Islands of the North Pacific Ocean," part III : 280-283. 1899. Thirty-seven species were collected, one a new species of Calandrinia, and 2 species were added. Dr. G. Dallas Hanna and J. R. Slevin, in July, 1923, visited the island in the interest of the California Academy of Sciences, and made a small collection and photographed the pines and cypresses. The last collection was that of H. L. Mason while botanical collector for the expedition of the California Academy of Sciences to the Revillegigedo Islands in 1925. Mr. Mason was on the island only two days (April 19-20), and in stormy weather, so that a small collection of only 43 species was made. Two weeds not before reported and nine topotypes were collected. In the present list of species the collector's name is given after each species with the exception of that made by Green, Wing and Thoburn. This is indicated as Dudley's list. Three lists have been made to show the relationship of the flora. The list of species first described from Guadalupe Island num- bers 51, the list from the mainland or islands off the coast of California numbers 74, while that of widely distributed species numbers 35. It will be seen from these lists, as well as from the general list, that the flora is related more to that of the mainland of California than to that of the peninsula of Lower California or the islands adjacent. It suggests a former con- nection with the mainland and is perhaps the remnant of another peninsula extending south and paralleling that of Lower California.

Hanna & Slevin collected cones from two dif- ferent trees, one having the large cone characteristic of the type and the other with cones as small and globular as those of Ciipressiis govcniana Gord. 9. Finns radiata biiiata (Engelm. ), Lemmon, West Am. Cone-Bearers 42. 1895. Type locality, Guadalupe Island. This pine differs from typical Pinus radiata in having two needles in a sheath instead of three, and much shorter leaves. The cones are much smaller, but are without prickles and are of the same shape as those of the type ; otherwise it might be referred to Pinus inuricata D. Don. Perhaps it should be regarded as a distinct species.

The type locality of this species, which Greene later transferred to Calliprora, is mountain summits back of Vacaville, California. It seems improbable that this rare species of which Greene claims to have been the only collector can be the same as the Guadalupe Island species. CUPULIFERffi ; Oak Family 24.

List of Plants recorded from Cedros Island, Mexico Cedros Island, the largest of the islands along the coast of Lower California, lies about 40 miles distant from the shore and midway of the peninsula. From the northern extremity it widens to about 9 miles at the south and is about 20 miles long. It is of volcanic origin and mountainous, with many peaks, the highest of which is less than 4000 feet elevation. Several collections of plants have been made on the island. In the present list the names of the collectors will be given in chronological order with each species. There have been three published lists and the species not on those lists have been taken from the scattered descriptions of Dr. Kellogg in the publications of the California Academy of Sciences and in revisions and monographs. There may be some that have been overlooked, as it is scarcely possible to be certain that every reference has been found. The first collection was made by Dr. Veatch. who visited the island in 1859 to investigate the reports of its mineral wealth. He brought back a small collection which he gave to the recently-founded California Academy of Natural Sciences, and the specimens were named by Dr. Albert Kellogg. Some of them were beautifully figured in colors in the Hesperian, later described in the publications of the California Academy of Natural Sciences, and all were new to science. Dr. Streets visited the island in 1876. collecting a few specimens, but no list was published. Mr. Lyman Belding made a small collec- tion in April, 1882, there being a few references to his speci- mens. The first important collection following that of Dr. Veatch was made by Dr. E. L. Greene in 1885. He spent three days in April and published a delightful description of Vol. XVIII] EASTWOOD— FLORA OF LOWER CALIFORNIA 421 the island and the trip in Pittonia 1 : 194-208. Eighty-two species were collected, 19 being new. In 1889, Lieut. Charles F. Pond of the U. S. Ship Ranger, while surveying the Lower Californian shores and islands, made a small collection on Cedros Island, which was listed by Dr. Greene in Pitt. 1 : 266- 268. Of nine species listed five were described as new. The next important collection was made by Dr. Edward Palmer, who spent five days on the island in March, 1889. The list of his collection was published by Dr. George Vasev and Dr. J. N. Rose in Contr. U. S. Nat. Herb. 1 : 13-20. He collected 97 species, six of which were new, and 44 were added to the known flora of the island. In 1897, T. S. Brandegee visited this island on the voyage of the Wahlberg and the list of his additions was published in Zoe 5:23. There were 31 species added, one new, namely Gilia wicialis Brandegee, a scrap of which is in the herbarium of the California Academy of Sciences. On the 1905-1906 expedition of the California Academy of Sciences to the Galapagos Islands a short stop was made on the island and a few plants collected by Alban W. Stewart. Dr. G. Dallas Hanna made a small collection when he visited the island in 1922. Dr. J. N. Rose and others have made some collections, but no lists of their plants have been published, their collections being occasionally noted in revisions and monographs. The last collection is that of H. L. Mason, the botanical collector on the expedition of the Cali- fornia Academy of Sciences to the Revillagigedo Islands in the spring of 1925. He collected 53 species from June 3-6, adding Asclepias subulata Dene., Dudleya Candida Britton, Dudleya sp., Polypogon monspcliensis Desv., Carex spissa Bailey, Eleocharis caribcca Blake, Acalypha californica Benth. In the present paper four lists have been made, the first being the 55 species which were first described from Cedros Island. Those in this list marked with a star are the types in the herbarium of the California Academy of Sciences, those marked with a dagger are topotypes in our herbarium. The second list consists of 33 species first described from Lower California or the mainland of Mexico. The third is a list of 64 species which were originally described from the mainland of California or Arizona. The fourth is a list of widely- distributed species consisting of 23, generally known as weeds. 422 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser.

A List of Plants Recorded from the Tres Marias Islands, Mexico The first list of plants from the Tres Marias Islands was published by Dr. J. N. Rose in N. Am. Fauna. U. S. Dept. Agr., No. 11, pages 77-91. It was based on a collection made the last of May at the close of the dry season in 1897 by E. W. Nelson and E. A. Goldman. One hundred and twelve species were recorded from Maria Madre, Maria Magdalena and Maria Cleofa islands, of which 1 1 were described as new. The next collection was that of H. L. Mason when on the expedition of the California Academy of Sciences to the Revil- lagigedo Islands in 1925. Collections were made on Maria Madre, Maria Magdalena and Isabella islands from May 16-24 at the end of the dry season and about 120 species were col- lected. Owing to the incomplete condition of most of the specimens, a duplicate set was sent to the United States Na- tional Herbarium for the authoritative determinations of Mr. Paul C. Standley, an authority on Mexican plants. In Octo- ber, 1925, Mrs. Roxana S. Ferris made a much better collec- tion, owing to the more favorable time of the year. She col- lected only on Maria Madre from October 21-27 and found 64 species, 10 being new, published with 4 plates in Contr. Dudley Herb. 1:65-81, the title of her paper being: Pre- liminary Report on the Flora of the Tres Marias Islands. The greater number of the species listed are of wide dis- tribution in the tropics, a few are peculiar to the adjacent mainland, and 21 have been described as new species, two of which are now considered synonyms. More extended and thorough exploration of these islands will undoubtedly dis- cover many more species. It is with the desire to help future explorers that these lists have been brought together.
