Perennial herb, 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: America (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.

Key to Cactaceae
Generally erect to ascending, [sprawling, pendent, or decumbent], branched or not, branches generally few–500, occasionally in dense mounds. Stem: 5–60cm, (1)4–15 cm diam, spheric to long-cylindric, soft, not regularly segmented; ribs prominent, 4–13, tubercles ± 0 along rib-crests. Spines: 4–55 per areole, < 2 mm diam, needle- to dagger-like, glabrous to puberulent, straight, curved, or curly; central spines (0)1–6(9). Flower: lateral, near distal margin of spine cluster; perianth purple to lavender, orange, or red [yellow or green]; ovary glabrous, spiny, scales minute. Fruit: spheric to obovoid, indehiscent or splitting laterally, densely spiny, spine clusters deciduous. Seed: 0.8–2 mm, obovoid to ± spheric, dull, wrinkled or tubercled, generally black.Key to Echinocereus
49 species: southwestern United States, Mexico. (Greek: hedgehog + Cereus) [Taylor 1985 The Genus Echinocereus. Timber Press]
Plant generally forming dense mounds to 1 m diam. Stem: 1–500, 5–40 cm, 5–15 cm diam, ± spheric to cylindric; ribs 5–12; tubercles ± prominent on ribs. Spines: 3–11 per areole, highly variable, generally gray; central spines (0)1–6, similar to radial spines, generally curved or curly and twisted. Flower: narrowly funnel-shaped. Fruit: 20–25 mm, spines minutely puberulent.
