Notes.

Acalypha bailloniana was considered as a subspecies of A. indica L. by Hutchinson (1913) and this treatment was followed in the subsequent floristic works. Radcliffe-Smith (1987, 1996) treated A. bailloniana as a synonym of A. indica . We consider that A. bailloniana is a distinct species which can be distinguished from A. indica by its dentante bracts with a prominent central tooth and with glandular hairs (vs. subentire bracts without prominent central tooth and without glandular hairs, in A. indica ). A. bailloniana is distributed in the east coast of tropical Africa and cited for the WIOR region for the first time, where it is probably introduced.
