 mon. All islands.

Fl. the whole year. Partly precocious in the spring. On dry hills 

 and in thickets. Virgin Islands (common) ; St. Croix (West, p. 288?). 



(West's E. cotinifolia, said to occur in St. Croix, is evidently meant for 

 this species. I doubt, however, the correctness of the habitat, and am 

 of opinion that it is a mistake for St. Thomas, where the species is ex- 

 ceedingly common.)
