A. B. RENDLE: MONOCOTYLEDONS. 217 
Differs from the original specimens collected by Scott Elliot 
on Ruwenzori, in its branched inflorescence, the branches being 
each a little shorter than the floriferous portion of the main 
shoot. This character is of interest, as the species has hitherto 
been contrasted with those most nearly allied to it by its simple 
inflorescence.
