452 MR. R. ALLEN ROLFE ON THE GENUS VANILLA. 
Folia 2-8 poll. longa, 1-22 poll lata. Bractes a poll. 
longe. Sepala et petala 13-1? poll. longe. Labellum 1; poll. 
longum. Columna 1 poll. longa. Capsula (ex Reichb. f.) 
“3-6 poll. longa.” 
Reichenbach describes the fruit as very aromatic and states 
that it yields the finest Vanilla which comes into the market, 
though how he obtained the infurmation cannot be ascertained. 
Part of the type specimen is in Lindley’s Herbarium, but is 
only in the flowering stage, while the fruits of other species 
of this group, so far as known, are not aromatic; so that, no 
other evidence of the occurrence of an economic species in 
New Granada being obtainable, some mistake must be 
suspected.

Only known from the original description. It is evidently 
allied to the preceding, but in what respect it differs is 
uncertain, both species being very imperfectly known.
