Characteristics

Evergreen, densely stellate-hairy shrubs. Leaves alternate or ±fasciculate, petiolate, very narrowly to broadly obovate or obcordate, conduplicate at first, slightly to very discolorous, penniveined but the veins obscure; stipules free, caducous to persistent, stellate-hairy throughout. Inflorescences terminal, comprising few-to many-flowered loose cymose panicles or densely contracted cymes (appearing umbellate); bracts caducous or persistent. Flowers long-pedicellate, bisexual, 5-partite, white to yellow or greenish, hypanthium tube short or absent. Sepals incurved to erect or ± spreading, persistent in fruit. Petals cucullate, clawed, erect, smooth, or absent. Stamens subequal to the petals, incurved to erect. Disc glabrous, forming a narrow, sinuous rim at the base of the hypanthium tube surrounding summit of ovary, or absent. Ovary inferior to half-inferior, with a densely pubescent roof; carpels 2; style glabrous or with base hairy, shortly lobed at the apex. Fruit an obovoid schizocarpic capsule; fruitlets crustaceous, splitting along their inner face to release the solitary seed. Seeds golden-to reddish-brown with dark base, aril translucent.
