I have doubtfully included as a synonym E. busseanum, H. Winkler, of which 
I have not seen a specimen. Judging from the description this has been drawn 
up from a plant bearing young male inflorescences ; I do not understand the 
description of the flower. Winkler makes no suggestion as to the affinity of 
the species. 
Var. conrauanum, Engl. lc. Leaves obliquely oblong, acuminate, margin
