the botanical works of those celebrated naturalists; and 
have consequently omitted the synonym adduced by Baron 
Jacquin from Willdenow as referring to a plant among 
those of Messrs. Humboldt and Bonpland. 
There are wild samples of the species in the Herbarium 
of Mr. Lambert, gathered by Dr. Anderson in the woods 
of the Island of St. Vincent, and recorded as above. There 
_is also in the same Herbarium a sample from Jamaica with 
a spike of flowers nearly a foot in length.

less, smooth, round, depressed above. lowers very
