Passiflora tessmannii Harms 1926
7. Passiflora tessmannii Harms (1926: 978) (Figure 7d) Type:— PERU. Loreto: Río Marañon, mouth of Río Santiago, 04°24’55”S 77°38’44”W, October 1924 (fl.), G. Tessmann 4385 (holotype: B (destroyed); lectotype US 00115118!). Notes:— Passiflora tessmannii is among a small group of species with a distinct umbrella-like structure (trochlea) developed along the base of the androgynophore. It produces masses of flowers on very short peduncles in arrangements of two per foliar node. The corona is short (<1 cm), apically dolabriform, with an erect, filamentose to papillose inner series. It is easily distinguished from the only other trochlea-bearing species (P. trochlearis Jørg. 1998: 379) by its broadly ovate (vs. ovate-lanceolate) leaves and Amazonian distribution. Only two records of P. tessmannii are known from east Ecuador, where this rare species is found in the transitional sub-Amazonian forests in the northern fringes of Cordillera del Condór of Morona-Santiago and Pastaza provinces. It is found growing along clearings and riverbeds of dense tropical wet forest at elevations between 800 and 1500 m above sea level.
