Perennial, shrub, tree, generally fleshy.
Stem: cylindric to spheric, or flat; surface smooth, tubercled, or ribbed (grooved); nodal areoles bearing flowers.
Leaf: generally 0 or early- deciduous, flat to ± cylindric.
Spines: areoles generally with central, radial spines, occasionally with glochids.
Flower: generally 1 per areole, bisexual [ unisexual], sessile, radial [ bilateral]; perianth parts generally many , scale-like to petal-like; stamens many; ovary inferior [superior], style 1, stigma lobes generally several [many].
Fruit: dry to fleshy or juicy, indehiscent to variously dehiscent, spiny, scaly, or naked; tubercled or smooth.
Seed: generally many, occasionally 0–few.
± 125 genera, ± 1800 species: Am (especially deserts), Africa; many cultivated, some edible. [Parfitt & Gibson 2004 FNANM 4:92–257] Spines smaller, fewer (0) in shade forms; yellow spines blacken in age. Introduced species increasingly escape cultivation. Hybridization common in some genera. Taxa of Escobaria in TJM (1993) moved to Coryphantha. —Scientific Editors: Bruce D. Parfitt, Douglas H. Goldman, Bruce G. Baldwin.
