454 MB. R. ALLEN ROLFE ON THE GENUS VANILLA. 
Folia 13-3 poll. longa, 1-13 poll. lata. Pedicelli 2 poll. 
longi. Sepala et petala 2 poll. longa. Labellum 14 poll. 
longum. Columna 1 poll. longa. 
Allied to the preceding, but readily distinguished by its 
three-lobed lip and longer fruit, which is probably not 
aromatic. The flowers are green. I have only seen a 
drawing.

the British Museum) from British Guiana, labelled ‘“ Dry 
savannahs, chiefly on skirts of woods, climbing on trees,” 
probably belongs here. The flowers are white with the front 
of the lip yellow.

This species has been curiously confused with Vanilla clavi- 
culata, Sw., and V. palmarum, Lindl., the former leafless and 
the latter easily distinguished by its terminal inflorescence and 
very short fruit. Grisebach appears not to have seen a specimen 
of what he calls V. palmarwm (apparently citing it from Wright’s 
note), but it probably belongs here, for there is no other
