b. Leaf apex emarginate or mucronate 2. Talinum triangulare
(According to Hutchinson & Dalziel (Fl. W. Tropical Africa I, 1: 136. 1954) these two species are very similar and almost indistinguishable morphologically and the only character that distinguishes them is the leaf apex. Nyananyo & Olowokudeju (l.c.) have found differences on the basis of palynology, seed morphology and leaf anatomy). 0
