Calyx tubular, campanulate, or cup-shaped, apex truncate to deeply lobed, sometimes with abaxial glands, leathery, falling with petals and stamens. Petals 5, usually red, sometimes yellow, orange, or white, obovate or obovate-lanceolate, asymmetrical, sometimes reflexed. Stamens 70-900, bases connate into short tube; filaments connate into 5-10 distinct phalanges, alternating with petals; anthers reniform. Ovary syncarpous, 5-locular; ovules many per locule; style filiform, longer than stamens; stigma stellately lobed. Capsule loculicidally dehiscent into 5 valves, valves woody or leathery, with silky wool inside. Seeds small, black, enclosed by wool.

Calyx closed in bud, truncate or lobed. Petals 5, tomentellous outside. Stamens many, adnate to the petals at their base, either in 2 whorls with the outer whorl of 5 epipetalous bundles and the inner whorl of 5 alternipetalous pairs, or in 5 epipetalous bundles; stamens united at their base into a short tube; anthers oblong or reniform. Ovary 5-locular, with numerous ovules; stigma 4-5-lobed or entire. Fruit a ± woody capsule, loculicidally 5-valved, with a persistent axis.
