Piliostigma Hochst.

Small deciduous trees, occasionally shrubby, not climbing. Tendrils absent. Leaves simple, conspicuously bilobed. Flowers medium to small, normally dioecious and unisexual, rarely monoecious, very rarely hermaphrodite (see F.C.B. 3: 278 (1952)), in terminal axillary or leaf-opposed racemes or panicles. Calyx with a turbinate tube and 4–5 short acute lobes. Petals 5. Fertile stamens 10 (in ♂ flowers), reduced to staminodes in ♀ flowers; filaments villous below. Stigma thick, capitate, flattened-globose, sessile on the ovary; funicle several times as long as ovule. Pods linear to oblong, many-seeded, leathery or woody, indehiscent. Seeds irregularly arranged, embedded in pulp, with a U-shaped line on one side; endosperm present.
