Drupe, indehiscent or 3-valvate dehiscent, exocarp fleshy to dry.

Petals 5, free or slightly united at base, valvate, usually glabrous.

Sepals 5, free, valvate, usually with hooked appendages at tip.

Petals (4 or)5, free, rarely slightly connate at middle, imbricate or valvate, rarely circinate.

Sepals (4 or)5, free or united at very base only, imbricate or valvate, persistent and clasping base of fruit.

Petals as many as calyx lobes, valvate, linear to lorate , sometimes basally coherent.

Sepals 4, valvate, persistent as hardened horns of fruit.

Sepals lanceolate, ca. 1 mm, valvate, outside hairy.

Capsule long ellipsoid, ovoid-ellipsoid, or ovoid, septicidal, 4- or 5-valvate.

Perianth lobes 4-9, imbricate or rarely valvate, persistent or caducous.

Corolla campanulate; lobes 5(--7), imbricate or valvate.

Capsule 4- or 5-valvate from apex when mature; seeds with round membranous wing.

Sepals 6, greenish white or purple, oblong, slightly fleshy, outer 3 valvate, inner 3 usually smaller.

Subshrubs or perennial herbs. Leaves 3-veined. Male perianth lobes 4(or 5), valvate; female perianth lobes 4, subequal, shorter than achene.

Petals 4-6, distinct, linear-oblong, imbricate to valvate in bud.

Petals 5, hooked, valvate.

Capsule globose or suborbicular, woody, apically 4- or 5-valvate when mature.

Petals 4 or 5, valvate in bud, connate apically and forming a calyptra, falling early.
