I found this very distinct species in 1838, growing in virgin 
forests. The axils are 14-1? inch apart; the leaves are 23-3

bearing eight or ten alternate slender patent spicated branches 
6-9 lines long. The terminal panicle is pyramidal, 6 inches 
long, and compound, consisting of a great many alternate
