X. occidentale is treated by P. Wilson, l.c., as a synonym of 
X. caribaeum Lam. which appears to be confined to the West 
Indies and the northern littoral of South America. It differs 
from the latter in the smaller leaflets with about twice as many. 
and more convex crenae, and in the non-suberose sepals. ?
