Origin/Endemic status: Native

Taxonomy Comments: Varieties or species have sometimes been maintained based on minor variation of pubescence; it is unlikely that these are taxonomically meaningful. Var. orientalis has the lower leaf surfaces, hypanthium, and style hairy (vs. glabrous or nearly so in var. dioica).
