Uvariopsis Engl.

Genus

Angiosperms > Magnoliales > Annonaceae

Characteristics

Trees or shrubs, the indumentum of simple hairs. Flowers unisexual (or at most a few stamens present in ♀ flowers), monoecious or dioecious, axillary, solitary or in fascicles, often on the old wood, pedicellate; bracteoles 2, one basal the other median, ± persistent. Sepals 2, connate to form a bilobed calyx, much shorter than the petals in bud. Petals 4, valvate, in one whorl, eventually spreading, free or somewhat joined, rather thick, those of the female flowers mostly larger. Stamens numerous, oblong to oblong-ovoid; filaments absent or very short; anther-cells extrorse; connective not or scarcely prolonged. Carpels numerous, obovoid or subcylindric, with several to numerous biseriate ovules; stigma sessile, cylindric, depressed obconic, lunate or horseshoe-shaped. Monocarps indehiscent, cylindric, ellipsoid or obovoid, stipitate, several-seeded, often somewhat constricted between the sieeds, usually succulent. Seeds horizontal, without an aril.
