Fleshy, climbing orchids, the leaves broad or reduced to mere scales, the 

 stems giving off aerial roots, the mostly large flowers in axillary spikes or 

 racemes. Sepals nearly alike, distinct, spreading. Petals resembling the 

 sepals. Lip clawed, the claw adnate to and embracing the long column. 

 Stigma borne under the rostellum. Anther convex, its sacs separate; pollinia

 [From the Spanish name for the fruit.] About 20 species, of tropical and 

 subtropical regions. Type species: Epidendrum Vanilla L. 



Plants leaf-bearing ; lip not lo'bed. 



Leaves l_anceolate, 4 cm. long or less. 1. V. Ef/gersii. 



Leaves Tinear-oblong, 7-12 cm. long, 1.5-2.5 cm. wide. 2. T'. phacantha. 



Plant leafless, except on youngest shoots ; lip 3-lobed. 3. T'. articiilaia. 



1. Vanilla Eggersii Rolfe, Jour. Linn. Soe. 32: 472. 1896. 



Fleshy, elongated, described as sometimes 30 m. in length and often 10 m. 

 long or longer, the stems terete, 1-grooved, 1-1.5 cm. thick, the aerial roots 5-8 

 em. long, tendril-like. Leaves sessile, oblong-lanceolate, acute or acuminate, 

 2-8 cm. long, 8-15 mm. wide; peduncle stout, geniculate, 5-10 cm. long, bearing 

 an ovate or oblong, acute bract at each node; spike several-flowered, 6-14 cm. 

 long, its bracts triangular-ovate, about 5 mm. long; ovary cylindric, about as 

 long as the sepals; sepals and petals oblong-lanceolate, obtuse or acutish, 4-6

Coastal thickets and coppices, Andros : — .Florida : Ilispaniola to Virgin Gordn, 

 Eggers' Vaxilla. Fawcett and Rendle (Fl. Jam. 2: 17) accredit Vutiilla rlarirulata 

 Sw. to the Bahamas, Porto Kico and St. Thomas, presumably including ]'. Kijtjcrsii 

 as a svnonvm of that species. This view may be correct, hut wp do not have speci- 

 mens to corroborate it. The petals of V. clavictihita are described as obtuse, while 

 those of V. Eggersii are acute.
