3-lobed at the apex, with the middle lobe much longer than the lateral ones, 

 the body with 5 longitudinal crests. Capsules erect. [Commemorates Joel

 Orchid. 



2. VANfLLA Juss. Gen. 66. 1789. 



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 

 powdery. Capsule elongated, fleshy, indehiscent or tardily partly dehiscent. 

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

 subtropical regions. Type species: Epidendrum Vanilla L. 



Plants leal-bearing: lip not lobed. 



Leaves lanceolate, 4 cm. long or less. 1. V. Eggersii. 



Leaves linear-oblong, 7-12 cm. long. 1.5-2 5 cm. wide. 2. V. pliacantha. 



Plant leafless, except on youngest shoots ; lip 3-lobed. 3. V. articulata. 



1. Vanilla Eggersii Rolfe, Jour. Linn. Soc. 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 

 cm. 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 

 cm. long ; lip about as long as the sepals, rounded, crenate or undulate, not 

 lobed ; column 2-2.5 cm. long ; capsule fleshy, indehiscent, cylindric or sub- 

 clavate, 7-12 cm. long, 8-10 mm. thick.

 N\v. to the Bahamas, Porto Rico and St. Thomas, presumably including T\ Eggersii 

 as a synonym of that species. This view may be correct, but we do nut have speci- 

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

 those of V. Eggersii are acute. 



2. Vanilla phaeantha Rchb.f. Flora 48: 274. 1865. 



Fleshy, often 6 m. long or longer. Leaves oblong or linear-oblong, nearly 

 sessile, 6-18 cm. long, 1.5-5 cm! wide, acute or obtuse; peduncle stout, 2-8 em. 

 long, geniculate, leafy -bracted ; spike few-several-flowered, its bracts ovate, 

 obtuse, 6-12 mm. long; ovary cylindric, 5-6 cm. long; sepals and petals nar-
