Three New Species of Passifora (Passifloraceae) from Ecuador and Notes on Passiflora viridescens Peter M. J0rgensen and John M. MacDougal Missouri Botanical Garden, P.O. Box 299, St. Louis, Missouri 63166-0299, U.S.A.ABSTR: rAT. Three species are described as new,viz., Passiflora trochlearis, P smilacifolia, and Pluzmarina. Ten species are reported as new for thecountry, viz., Ancistrothyrsus hirtellus, P tessmannii,P. putumayensis, P pittieri, P viridescens, P biflora,P. candollei, P glaberrima, P. caerulea, and P aff.kermesina. Five species are mentioned that ap-peared in the literature since the publication of thePassifloraceae in the Flora of Ecuador as eithernew taxa or as extensions of distribution into Ec-uador, viz., P morifolia, P brachyantha, P linda,P. jatunsachensis, and P chrysosepala. Three taxahad misapplied names in the flora; these misun-derstandings are rectified. The total number of gen-era and species in Ecuador is 3 and 92, respec-tively, an increase of 15 taxa, or 20% in less than10 years.RESIt MIN. Se describen Passiflora trochlearis. Psmilacifolia y P. luzmarina como nuevas. Las diezespecies siguientes son, por primera vez, reportadaspara el Ecuador: Ancistrothyrsus hirtellus, P. tess-mannii, P putumayensis, P pittieri, P viridescens,P biflora, P. candollei, P glaberrima, P caerulea yP aff. kermesina. Las cinco especies siguientes hansido reportadas en la bibliograffa desde la publi-caci6n de la "Flora of Ecuador": Passflora mori-folia, P brachyantha, P linda, P jatunsachensis yP chrysosepala. Tres taxones fueron tratados bajonombres equivocados en la Flora; estas equivoca-ciones se rectifican aquf. El niumero total de ge-neros y especies en el Ecuador son 3 y 92 respec-tivamente, esto significa un incremento de 15taxones, o del 20% en menos de 10 afios. Since the publication of Passifloraceae in the Flora of Ecuador (Holm-Nielsen et al., 1988), Es-cobar (1992), MacDougal (1994), Panero (1996), and Schwerdtfeger (1997) reported Passiflora brachyantha L. K. Escobar, P. morifolia Masters, P. linda Panero, P jatunsachensis Schwerdtfeger, P. chrysosepala Schwerdtfeger, and P. ulmeri Schwerdtfeger, respectively. Three misapplications of names made in the Flora of Ecuador (Holm-Niel-sen et al., 1988) are here rectified, and P ulmeri is synonymized with P viridescens L. K. Escobar.We are here describing 3 new species and can re-port the following 10 as new for the country: An-cistrothyrsus hirtellus A. H. Gentry, Passiflora tess-mannii Harms, P. putumayensis Killip replaces P.arborea Spreng sensu Holm-Nielsen et al. (1988),P pittieri Masters, P viridescens L. K. Escobar, Phiflora Lamarck, P candollei Triana & Planchon, Pglaberrima (Jussieu) Poir., P caerulea L., and P aff.kermesina Link & Otto. The Flora of Ecuador included 2 genera and 77species, and listed 1 additional genus as expected,but not documented. The total number of Passiflor-aceae in Ecuador is now 3 genera and 92 species.We describe the new species and emend the de-scription of Passiflora viridescens to be able to usethe information in the Catalogue of Vascular Plantsof Ecuador (J0rgensen & Le6n, in prep.). The citedauthor of each new species provided the respectivedescriptions.Passiflora trochlearis P. Jorgensen, sp. nov. TYPE: Ecuador. Pichincha: Reserva ENDE-SA, Quito-Puerto Quito road at km 113, 650-800 m, 0�03'N, 79007'W, 23 Jan. 1987 (fl), P J0rgensen 61637 (holotype, QCA; isotypes, AAU(3), MO). Figure 1. tiHec species a IPssiflora renosa Rushy petiolis lon-gioribus: glandulis. supra petiolos et costas oblongis: in-florescentia axillari ex cvma centrali in cirrhum longumcvoliita et cvlmis lateralibus brevibs constante differt. Liana, stem to 1.5 cm diam., puberulent, indu-mient light brown, to 0.1 mm. Stipules 1.5 mm, del-toid, very early deciduous; petioles 2.0-4.0 cm, theglands 2 X 0.7 mm, elliptic, scarlike, reddishbrown, confined to the midrib at junction betweenleaf blade and petiole; leaf blades 6.5-14.7 X 4.0-9.5 cm, unlobed, ovate, entire, the base truncate orrounded, the apex acute, chartaceous, 6-10 lightbrown lateral nerves per side, above green and pu-bescent along nerves, below olivaceous green,white-puberulent. Inflorescences axillary, simple orcompound dichasiums, the central cyme or flowerdeveloped into a long-lasting tendril, old tendrilswith barely visible scars from the lateral cymes,apparently a maximum of two flowers flowering per NOVON 7: 379-386. 1997.
