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
Erect or leaning, branches 0, occasionally branched from tip-injury. Stem: (0)10–200(300) cm, 10–35 cm diam, depressed-spheric to short-columnar, hard, glabrous, not segmented; ribs 13–31, prominent; tubercles not conspicuous on ribs. Spines: 10–32 per areole, 2–4.5 mm wide, generally awl-shaped, generally flat, ringed with conspicuous ridges, straight to curved or ± hooked, some bristle-like; central spines generally 4 per areole. Flower: ± terminal, near distal edge of spine cluster, 3–6 cm diam; perianth yellow to red [or purple, or white with ± purple midstripes]; ovary glabrous, spines 0, scales numerous, generally rounded, margins minutely fringed or toothed. Fruit: spheric, ovoid, or cylindric, glabrous, spineless, dehiscent by basal pore. Seed: 1.5–3 mm, spheric to subreniform, pitted, black.Key to Ferocactus
25 species: southwestern United States, Mexico. (Latin: fierce cactus) [Taylor 1984 Bradleya 2:19–38]
Stem: taller than wide, spheric to columnar. Spines: 10–32, erect and spreading, longest generally recurved to ± hooked, hooked on immature plants, generally ± red [yellow], gray in age. Flower: inner perianth occasionally orange to red; style 12–20 mm, ovary 9–12 mm, scales fringed. Fruit: yellow. Seed: 1.5–3 mm.
2n=22. Gravelly, rocky, or sandy areas; 60–1500 m. Desert (especially e Mojave Desert, w Sonoran Desert); to southwestern Utah, Arizona, northern Mexico. [Ferocactus cylindraceus var. lecontei (Engelm.) Bravo] Formerly recognized varieties untenable. Threatened by collecting; monitoring needed. Apr–May [Online Interchange]
Unabridged synonyms: [Echinocactus cylindraceus Engelm.; Ferocactus acanthodes (Lem.) Britton & Rose, misappl. (rejected name)]
Unabridged note: The name Ferocactus acanthodes has been used for this sp. but its use is ambiguous because the type is lost and its identification is uncertain.
