In foliage this species approaches O. coriacewm and several others; but it differs 
from any other species of the genus (as defined in Bentham and Hooker's ‘Genera 
Plantarum’) in having only 2 cells in the ovary. However, as the species included 
vary in this respect in having from 3 to 7 cells in the ovary, it seems that our plant is 
admissible.
