Woody climbers, without prickles. Leaves usually ± ovate, base 3–5-veined. Inflorescences axillary, subracemose, without accrescent bracts. Male flowers: sepals usually 6 in 2 whorls, sometimes 1 or 2 additional reduced outermost whorls present, imbricate; petals 6, auriculate towards base, clasping the opposite stamen; stamens 6, free. Female flowers: staminodes 6; carpels 3; style reflexed; stigma entire. Drupes without carpophore or stipe, with style-scar near base; endocarp bony, ± obovoid, subcompressed, rather smooth, laterally perforate, with a central hollow condyle around which the seed is strongly curved. Seed without endosperm; cotyledons large, thick.
