Opuntia chlorotica

PANCAKE PRICKLY-PEAR


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.

Genus: OpuntiaView DescriptionDichotomous Key


Common Name: PRICKLY-PEAR
Habit: Shrub, tree; roots fibrous [tuberous]. Stem: generally erect, < 6 [12] m; segments generally flat (+- cylindric), generally firmly attached; tubercles 0 to +- developed; ribs 0. Leaf: small, conic, fleshy, deciduous, present on young stems, ovaries. Spines: 0--many per areole, cylindric or flat, tip smooth or barbed, epidermis persistent; glochids generally many. Fruit: juicy, fleshy or dry; wall thick, bearing areoles; spiny or not. Seed: in a bony, +- white aril.
Etymology: (Possibly from Papago name ("opun") for this food pl; or for a spiny plant of Opus, Greece) Note: Spines smaller, fewer in shade forms; yellow spines blacken in age. Spineless stems, ovaries, and fruit generally with glochids, these occasionally long, conspicuous; hybridization common. Taxa with cylindric to club-shaped stems moved to Cylindropuntia, Grusonia.

Opuntia chlorotica Engelm. & J.M. Bigelow
NATIVE
Habit: +- tree-like. Stem: 1.5--2 m; branches ascending; segments 13--20 cm, generally round, glabrous. Spines: 3--8 in at least distal areoles, longest 2.5--5 cm, generally straight, flat, +- reflexed, translucent yellow. Flower: inner perianth 2--2.5 cm, yellow; filaments white; style white, stigma yellow-green. Fruit: +- 4 cm, juicy; exterior purple-red; middle layer white, seed-pulp pink; areoles 40--70. Seed: 3 mm. Chromosomes: 2n=22.
Ecology: Pinyon/juniper woodland, desert scrub edge, chaparral; Elevation: 600--1300 m. Bioregional Distribution: e PR, DMoj (desert mountains and lower montane slopes, canyons); Distribution Outside California: to Nevada, New Mexico, northern Mexico. Flowering Time: May--Jun Note: If recognized taxonomically, stabilized hybrids with Opuntia phaeacantha in DMtns (New York Mountains, eastern San Bernardino Co.), southern Nevada, western Arizona assignable to Opuntia curvispina Griffiths (2n=44).

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.
