DESERT PINCUSHION


Higher Taxonomy
Family: CactaceaeView DescriptionDichotomous Key
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. Taxa of Escobaria in TJM (1993) moved to Coryphantha.

Genus: CoryphanthaView DescriptionDichotomous Key


Common Name: BEEHIVE CACTUS
Habit: Generally erect, not branched, or if branched then forming low +- 50 cm diam clumps with up to 12[200] branches. Stem: not segmented; 2--15 cm, 2--15 cm diam, spheric, ovoid, or cylindric, soft-fleshy to firm, ribs 0, tubercles conic to cylindric, grooved along distal surface from base (axil) to spine cluster at tip. Spines: 3--95 per areole, < 1 mm diam, needle-like, smooth, straight [curved or hooked]; central spines 3--12. Flower: +- at stem tip, in axil of tubercle; 6--37[100] mm diam; perianth +- yellow-green to rose-pink or +- purple; ovary glabrous, spines 0, scales generally 0--few, fringed [entire]. Fruit: indehiscent, wide-ellipsoid to narrowly obovoid, spineless. Seed: 1.3--2.3 mm, reniform, pitted, black or brown.

Ecology: Limestone soils; Elevation: 1000--2400 m. Bioregional Distribution: D (e San Bernardino Co.); Distribution Outside California: to southwestern Utah, northwestern Arizona. Flowering Time: Apr--May
Synonyms: Escobaria vivipara (Nutt.) Buxb. var. deserti (Engelm.) D.R. Hunt; Coryphantha deserti (Engelm.) Britton & Rose; Coryphantha vivipara (Nutt.) Britton & Rose var. deserti (Engelm.) W.T. Marshall; Escobaria deserti (Engelm.) Buxb.; Mammillaria deserti Engelm.
Unabridged Note: Fresh flowers or reliable flower data required to distinguish Coryphantha chlorantha from Coryphantha vivipara var. rosea when growing together.

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.
