Common Name

English: warakabakoro


According to Trelease and Yuncker (1950: 380), specimens in NY with the type number, Hostmann 312, belong to Piper hispidum var. trachydermum.
Trelease and Yuncker (1950: 378) placed Piper lenormandianum C. DC. in synonymy of P. kappleri. While studying the Kew type specimen of the latter I had to conclude that this specimen is clearly different and belongs to P. demeraranum instead of to P. cyrtopodum.
The numbering of the Sagot collections poses a problem here. Sagot 844 at K is certainly P. demeraranum. Specimens with the same number 844 in NY and P are correctly assigned to P. wachenheimii. The two species are clearly separable by the shape of the leaves. We have to conclude that 844 is not an exclusive number for the species mentioned.
