evidence that that species grows in the West Indies, and 
Lindley himself wrongly labelled Hostman’s specimen cited 
above as V. palmarum. V. palmarum var. grandifolia, Cogn., 
is referred here with some doubt, on account of its much 
longer Jeaves, which are described as about 5 inches !ong.

Readily distinguished from the preceding, which has been 
confused with it, by its terminal inflorescence and very short 
fruit, which is very distinctly calyculate. There is no clear 
evidence that this species grows in the West Indies, for all the 
so-called West Indian specimens which I have seen belong to 
the preceding.
