Only a single sterile stem and part of a fertile stem were collected of tbis ; 

 sufficient, however, to show it to be one of the finest species of the genu?, 

 wliile the single capsule fortunately present establishes it as a very clearly 

 defined species. The only species at all approaehing it in the form and size 

 oC the capsule is B. arimdimfoUa^ in which ] have seen an occasional capsule 

 5-6 mm. long, and almost of the same form. The fruit of B, aaplnjlla 

 {AVil*,)^ "which resembles it in habit and in the le:if-base, has not yet beou 

 found. 



The character of the kavcs is ver\^ striking ; they resemble much those of 

 B. acipJiglla, from the Andes of Quito, but are narrower and more strongly 

 serrate, with the basal part still more strikingly orange, the whole base in 

 fact highly coloured, wliile in the loaves I have examined of Wilson's plant 

 th(^ lower part only of the base is so (this may, bow^over, be dependent on 

 age). A[)art froin this the narrow Uj>[)er cells with the walls highly incras-
