Common Name: CACTUS FAMILY Habit: 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. Genera In Family: +- 125 genera, +- 1800 species: America (especially deserts), Africa; many cultivated, some edible. Note: Spines smaller, fewer (0) in shade forms; yellow spines blacken in age. Introduced species increasingly escape cultivation. Hybridization common in some genera. eFlora Treatment Author: Bruce D. Parfitt, except as noted Scientific Editor: Bruce D. Parfitt, Douglas H.

Common Name: HEDGEHOG CACTUS Habit: Generally erect to ascending, [sprawling, pendent, or decumbent], branched or not, branches generally few--500, occasionally in dense mounds. Stem: [2]5--60[200] cm, (1)4--15 cm diam, spheric to long-cylindric, soft, not regularly segmented; ribs prominent, 4--13[26], tubercles +- 0 along rib-crests. Spines: [0]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.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
