REMARKS

Operculicarya hirsutissima is a small tree known only from the area around Ihosy and Sakaraha in South- Central Madagascar (Fig. 1). It can be distinguished from the other species whose leaves have a winged rachis by its small, densely villous leaflets bearing secondary venation that is slightly impressed (vs. prominently raised) on the lower surface.

VERNACULAR NAMES

Beoditra (= Behoditra), Botiboty, Sakoakomba.
