(from Greek words referring to the beauty of parts of the flower). Asclepiadaceae. Milkweed-like shrubs, or small trees, grown in the American tropics and one species offered in southern California.

Branching, glabrous or tomentose-canescent: leaves opposite, subsessile, broad: flowers with 5-parted calyx glandular inside; corolla bell-shaped or somewhat rotate, 5-parted with broad lobes; crown of 5 narrow fleshy scales adnate to the staminal tube and free and recurved at the base; pollinia solitary in each cell, obovate-oblong and compressed, hanging from the apex: fruit short horned gibbous acuminate pods mostly in pairs; seeds with silky hairs. - Three species in tropical Asia and Africa, sometimes grown under glass in collections but in this country practically confined to the tropics. The bark of C. gigantea produces a strong fiber, and the acrid milky juice dries into a substance like gutta-percha. The silk on the seeds is used in fabrics by natives; that of C. procera is said to be exported from the Cape Verde Isls. as kapok (kapok is usually from the ceiba or silk-cotton tree).
