Notes
Stapf (in F.C. 4, 2: 463 (1904) and in F.T.A. 4, 2: 565 (1906)) considered Pretrea senecioides, P. artemisiaefolia, P. loasifolia and P. forbesii as conspecific with Dicerocaryum zanguebarium (Lour.) Merr. from Tanzania and Madagascar. M collections from the Flora Zambesiaca area belong to Subsp. senecioides (Abels in Mem. Soc. Brot. 25: 219 (1975)).
