laminarum instructo, lamellis lamine appressis laciniatis, 
laciniis hyalinis reflexis; columnd curvaté cum basi labelli 
coalita. 
Hab. W. Trop. Africa, South Cameroons, Brawn; 4. 
Folia 4-6 poll. longa, 14-24 poll. lata. Flos 1 poll. longus. 
Apparently allied to the preceding, but the lip not nearly 
so much united to the column, and seemingly different in 
shape. 
13. Vanitea ramosa, Rolfe; caule subgracili; foliis petiolatis 
oblongis vel elliptico-oblongis breviter acuminatis subobtasis ; 
racemis subbrevibus swpe parce ramosis, bracteis ovatis sub- 
obtusis; sepalis petalisque oblongo-lanceolatis subacutis sub- 
wequalibus ; labello profunde trilobo, lobis lateralibus transverse 
oblongis, lobo intermedio oblongo subacuto margine crenulato 
reflexo-plicato, cristé foliolis ramentaceis composita; columna 
clavata. 
Vanilla, sp., Lindl. in Journ. Linn. Soc. (Bot.), vi. (1862) 
p. 137. 
Hab. W. Trop. Africa. Niger, about Angiama, abundant, 
Barter, 20134! Interior of Western Lagos, Rowland ! 
Folia 4-6 poll. longa, 1-2} poll. lata; petiolus $-? poll. 
longus. Racemi 14-2 poll. longi. Bracteew 1-2 lin. longe. 
Sepala et petala 10-12 lin. longa. Labellum 7-8 lin. longum. 
Columna 7-8 lin. longa. Capsula non visa. 
This differs from the two preceding species in its much 
broader leaves, and in the details of the flower. The branched 
inflorescence is remarkable. Nothing is known about the 
fruit.
