Professor Oliver, who has kindly examined these specimens, 
finds no difference, beyond the more luxuriant habit, between 
them and others from South Africa, where it abounds from 
Uitenhage to Macalisburg. He further identifies it with C. ani- 
sata of Cape Coast, and considers it scarcely distinguishable 
from C. Willdenovii of India, except by the collateral insertion of 
the ovules.
