Receptacle not produced into a tube beyond ovary, with numerous, ± leafy, often persistent scales. Perianth multiseriate; segments free, spreading or rotate, white to red, magenta or orange. Stamens numerous, inserted at base of perianth. Ovary (pericarpel) superior to inferior; placentas basal or parietal. Fruit globose, pear-shaped, or obovoid, fleshy, with or without scattered, leaflike scales. Seeds 2 to numerous; testa glossy black, brittle.

Stems straight or zig-zag. Spines 1-12 per areole.
