Oxyanthus versicolor. Bot. Reg. 1840. mise. no. 150. 
I referred this at first to the African genus Oxyanthus, 
and now I prefer the Posoquery of Guiana; the truth being 
that the plant does not belong exactly to either. With 
Oxyanthus it corresponds in the absence of hairs from the 
throat and in the long filaments, with Posoqueria in the oblique 
corolla; from Oxyanthus it differs in the latter circumstance, 
from Posoquery in its naked throat and very prominent an- 
thers. Upon full consideration of the differences between 
those genera, it appears that the essential points are the ob- 
lique corolla of one and the regular one of the other ; and in 
this point of view the plant before us is a Posoquery. 
__* Aymara Posoqueri is the native name among the Caribs of the 
original species.
