Shrubs or trees with an indumentum of simple hairs
Flowers hermaphrodite, solitary or fascicled, axillary on leafy shoots and/or also on the old wood, sessile or stalked; bracteoles 2–6, often forming an involucre in the case of sessile flowers
Sepals 3, valvate, free or united at the base, in most species not enclosing the petals in bud
Petals 6, in 2 whorls of 3, the outer valvate, and at length spreading, the inner valvate or somewhat imbricate above, open below, often remaining connivent at apex long after flowers have opened, free, mostly very thick and fleshy, often brittle, subequal
Stamens very numerous, linear; anther-cells lateral or extrorse; connective-prolongations capitate
Carpels numerous, cylindric, with numerous mostly biseriate ovules or in one species practically in 1 row; style very short or more developed, consisting of a plicate or involute lamina, the apical margin being the stigmatic surface
Monocarps indehiscent, ovoid, ellipsoid or broadly to narrowly cylindric, straight, subsessile or shortly stipitate, many-seeded, often constricted between the seeds
Carpels ?, cylindric, with numerous ovules in two rows; style very short; stigma truncate, horse-shoe-shaped.
Ripe carpels indehiscent, ovoid or ellipsoid to cylindric, straight, subsessile, many-seeded.
Petals 6, in two whorls, the outer valvate, the inner valvate above and open below, expanding and spreading at anthesis or the inner whorl remaining connivent at the apex, free, subequal, thick.
Stamens very numerous, linear, with thecae lateral or extrorse and connective-prolongations capitate.
Shrubs or trees, not climbing, with simple hairs.
Bracteoles 2–6, usually biseriate, forming an involucre in sessile flowers.
Sepals 3, valvate, free or united at the base, not enclosing the petals in bud, with plane margins, densely brown- or golden-sericeous outside, glabrous within.
