Previous taxon


Bruce D. Parfitt, except as noted

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 [5], 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


Marc Baker, Bruce D. Parfitt & Jon Rebman

Shrub or small tree, erect to decumbent, many-branched. Stem: regularly segmented, segments generally < 50 cm, < 5 cm diam, cylindric, fleshy, glabrous; ribs generally 0; tubercles generally elongate. Leaf: deciduous. Spines: 1–many per areole, < 2 mm diam, generally needle-shaped, smooth, straight, tip smooth or barbed, epidermis separating as a papery sheath; central spines generally not distinct from radial spines; glochids generally numerous in each areole. Flower: lateral to terminal, from distal portion of areole, 1.8–8 cm diam; perianth yellow, green-yellow, orange-yellow, to bronze, pink, or red; ovary glabrous, spines 0–many, glochids many in each areole, scales 0. Fruit: indehiscent; spheric or cylindric to obconic, dry or fleshy to leathery in age, green to dark yellow, glabrous, spiny or spines 0. Seed: 1.9–7 mm, flattened to ± spheric, surface smooth to angular, within an aril, bony and ± white when dry.
35 species: America. (Cylindric Opuntia) [Pinkava 2002 Succ Plant Res 6:59–98] Hybridization common. Young buds of some species used as for food, many species for ornamental.

Key to Cylindropuntia

C. ×fosbergii (C.B. Wolf) Rebman et al. MASON VALLEY CHOLLA, PINK TEDDY-BEAR CHOLLA
Plant < 2.5 m. Stem: trunk 1; branches generally several, long, generally curving upwards; terminal segments generally < 10 cm, 4–6 cm diam, easily detached; tubercle 10–20 mm, 3–5 mm high. Spines: 7–10, < 2.5 cm, pale red-brown, sheath pale yellow-brown. Flower: inner perianth < 2.5 cm, pale red-brown; filaments green. Fruit: dry to leathery, tubercled, proximal tubercles ± = distal; base generally obtuse; spines 0 or few, thin, deciduous. Seed: < 3 mm, generally sterile.
2n=33. Valley floors, alluvial fans; 300–450 m. Sonoran Desert (e San Diego Co.). [Opuntia fosbergii C.B. Wolf; Opuntia ×fosbergii] Mar–May [Online Interchange] {CNPS listed}
