456 MR. R. ALLEN ROLFE ON THE GENUS VANILLA. 
cristata, infra medium carinam papillosam ad basin extensa, 
ramentaced ornato, columna brevi. 
Hab. W. Trop. Africa, Loddiges! Brass, Niger Territory, 
Barter, 47! Mt. John, Kongui River, Mann, 1881! 
Folia 2-5 poll. longa, 4-14 poll. lata. Racemi ? poll. longi. 
Sepala et petala non visa. Bractes 14 lin. longe. Labellum 
8 lin. longum. Columna 3 poll. longa. 
This species is very remarkable in the shape of the lip; 
Lindley, who received a flowering branch from Loddiges, 
unfortunately did not preserve the sepals and petals, though 
he both sketched and carefully dried the lip and column. No 
other specimens are in flower, but they appear to belong to the 
same species. 
11. V. acuminata, Rolfe; caule subgracili; foltis petiolatis 
lanceolatis vel oblongo-lanceolatis acuminatis ; racemis brevibus, 
bracteis ovato-oblongis subobtusis; sepalo postico lanceolato, 
sepalis lateralibus lanceolato-oblongis; petalis falcato-lanceo- 
latis omnibus acutis; labello profunde trilobo, lobis lateralibus 
rotundato-oblongis obtusis, lobo intermedio oblongo obtuso 
apiculato; disco medio ramentaceo vix cristato; columna 
clavata. 
Hab. W. Trop. Africa. Gabon, in the province of Munda, 
Soyaux, 134. “ Frequent in woods, but seldom flowers.” 
Folia 6-7 poll. longa, 1-1} poll. lata; petiolus } poll. longus. 
Racemus 1 poll. longus. Bractee 14-4 lin. longew. Sepalum 
posticum 10-12 lin. longum, 3 lin. latum; sepala lateralia 
4 lin. lata. Petala 9-10 lin. longa, 22 lin. lata. Labellum 
7-8 lin. longum. Columna 6-7 lin. longa. 
Allied to the preceding species, but the stem stouter, leaves 
and bracts longer, and the lip quite differently shaped. The 
crest is unusually small, being reduced to a few scaly 
appendages.
