Uvariastrum Engl. & Diels

Shrubs or small trees, glabrous or with an indumentum of simple hairs (or also stellate in U. modestum Diels). Flowers hermaphrodite or rarely unisexual, axillary, solitary or paired, sometimes borne on the old wood; buds conical; bracteole 1, usually deciduous. Sepals 3, valvate, free, enclosing the petals in bud, at which time the margins form wing-like ridges (see below), often densely ferruginous pubescent. Petals 6, in 2 whorls of 3, usually both valvate but with inner whorl imbricate in one species, free, subequal. Stamens numerous, linear, the cells lateral or extrorse; prolongation of the connective ± capitate; filaments very short. Carpels 3–15 (or more), cylindric or obconic, sometimes angular, free, with numerous biseriate ovules; style very short; stigma broadened, bilobed or irregular, rugose or verrucose. Monocarps indehiscent, ellipsoid or cylindric, stipitate, few–many-seeded, somewhat constricted between the seeds, usually succulent. Seeds ± horizontal, without an aril.
