Trees or shrubs, not climbing, glabrous or with an indumentum of simple hairs. Flowers hermaphrodite, solitary or in 2–many-flowered cymes or fascicles, extra-axillary, axillary or leaf-opposed or sometimes on leafless branches or on the trunk; bracts and bracteoles present. Sepals 3, valvate, much smaller than the petals. Petals 6, in 2 whorls of 3, both valvate, free, subequal or the outer slightly larger, variously shaped, linear, lanceolate, ovate, elliptic, oblong or obovate, often quite large and showy, red, orange, yellow, green or white. Stamens mostly numerous, cuneiform; filaments very short; connective-prolongations flat-topped or slightly convex, covering the anther-cells, rhomboid or round in plan. Carpels few to numerous, free, oblong, 1–5-ovuled, the ovules basal or superposed; style absent or almost so; stigma rectangular, globose or irregularly shaped, with a faint groove on inner side running down inner side of the ovary. Monocarps few to many, indehiscent, ellipsoid, ovoid or subglobose, stipitate or subsessile, 1–5-seeded. Seeds sometimes with a longitudinal circumferential groove.
Trees or shrubs. Inflorescences axillary, internodal, or leaf-opposed, sessile or shortly pedunculate, 1-to many flowered. Flowers usually bisexual. Sepals 3, usually small, valvate or rarely subimbricate in bud, free. Petals 6, in 2 whorls, free, valvate or rarely subimbricate in bud, subequal, flat and spreading; inner petals sometimes slightly larger or smaller than outer, concave and arched over stamens. Stamens usually many; anther locules cuneate; connectives apically orbicular or rhomboidal, concealing anther locules, apex flat-topped or slightly convex. Carpels rather few to many, free; ovules 1 or 2(or 3) per carpel, basal or sutural; styles absent, very short, or long; stigmas mostly dilated. Fruit apocarpous; monocarps few to many, short to long stipitate, mostly globose or ovoid, fleshy. Seeds 1 or 2(or 3) per monocarp, with a longitudinal circumferential groove.
