one, which extends from the Amazon (which it ascends to the 
junction of the Rio Negro), to Venezuela, Columbia, Guate- 
mala, and St. Vincent ; but which, curiously enough, has not 
been detected in Trinidad. The C. albiflora of the Morist 
is clearly the same, with the articulation of the pedicels 
and bracteoles omitted by the artist. The specimen here 
figured flowered in January of the present year in Mr. Bull’s © 
establishment at Chelsea.

nerves reticulate; petiole one quarter to half an inch long. 
Stipules small, subulate, deciduous. Mowers usually in
