Description
Family Cactaceae
Fleshy
perennials
, shrubs
, trees
or vines
, terrestrial
or epiphytic. Stems jointed
, terete
, globose
, flattened, or fluted
, mostly leafless and variously spiny
. Leaves alternate, flat or subulate
to terete, vestigial, or entirely absent; spines, glochids (easily detached, small, bristlelike spines), and flowers always arising from cushionlike, axillary
areoles (modified short shoots
) . Flowers solitary, sessile, rarely clustered and stalked
(in Pereskia), bisexual
, rarely unisexual
, actinomorphic
or occasionally zygomorphic. Receptacle tube
(hypanthium or perianth tube) absent or short to elongate
, naked or invested with leaflike bracts, scales
, areoles, and hairs
, bristles
, or spines; perianth segments usually numerous
, in a sepaloid
to petaloid
series. Stamens numerous, variously inserted
in throat
and tube; anthers
2-loculed, dehiscing longitudinally. Ovary (pericarpel) inferior, rarely superior, 1-loculed, with 3 to many parietal
(rarely basal) placentas; ovules usually numerous; style 1; stigmas 2 to numerous, papillate
, rarely 2-fid. Fruit juicy or dry, naked, scaly
, hairy
, bristly
, or spiny, indehiscent or dehiscent
, when juicy then pulp derived from often deliquescent funicles
(except in Pereskia) . Seeds usually numerous, often arillate
or strophiolate
; embryo curved
or rarely straight; endosperm present or absent; cotyledons reduced or vestigial, rarely leaflike.
About 110 genera and more than 1000 species: temperate
and tropical
America; Rhipsalis baccifera (J. S. Mueller) Stearn native
in tropical Africa, Madagascar, Comoros, Mascarenes, and Sri Lanka; some species of other genera now extensively naturalized
in the Old World through human agency; more than 60 genera and 600 species cultivated as ornamentals
or hedges
in China, of which four genera and seven species more or less naturalized.[1]
Genus Opuntia

, appearing continuous with age, main axis determinate, usually terete
. Stem segments green or sometimes reddish to purple, usually flattened, circular, elliptic
, ovate
, lanceolate, or obovate
to oblanceolate
, 2-60(-120) × 1.2-40 cm, nearly smooth
to tuberculate
, glabrous
or pubescent
; areoles usually elliptic, circular, or obovate, 3-8(-10) × 1-7(-10) mm; wool white, gray, or tan to brown, aging
white or gray to black. Spines 0-15+ per areole, white, yellow to brown, red-brown to gray, or black, sometimes partly to wholly white chalky (chalkiness disappearing when wet), aging gray to dark brown to black, with epidermis
intact, not sheathed, acicular
to subulate
, sometimes setose
or with hairlike bristles
, terete to angular-flattened, to 75(-170) mm, tips
sometimes paler or yellow. Glochids in adaxial
crescent at margin
of areole, in tuft or encircling areole margin, white to yellow to brown, or red-brown, aging white to brown or red-brown. Flowers bisexual
or sometimes functionally staminate
, radially symmetric
; outer tepals green to yellow with margins tinged color of inner tepals; inner tepals pale
yellow to orange, pink to red or magenta, rarely white (unicolored) or with base
of a different color (bicolored
), oblong
to spatulate
, emarginate-apiculate; nectar chamber simple
, open, not covered by proximal
thickening style. Pollen yellow, grains reticulate
or foveolate (opuntioid type). Fruits sometimes proliferating (sprouting from another fruit), if fleshy
, green, yellow, or red to purple or, if dry, tan to gray, straight, sometimes stipitate
, clavate
to cylindric
, ovoid
, or obovoid
to subspheric, 10-120 × 8-120 mm, fleshy to juicy or dry, smooth or tuberculate, spineless or spiny
, sometimes burlike. Seeds pale yellow to tan or gray, generally circular to reniform
, flattened (discoid
) to subspheric, angular to squarish, sometimes warped, 2-7 × 2-7 mm, glabrous, commonly bearing 1-4 large, shallow depressions
due to pressures
from adjacent
developing seeds; girdle
protruding 0.3-3.5 mm, forming ridge
or flat wing
, or not protruding. x = 11.
Species ca.
150 species: widespread in North America, Mexico, West Indies, South America, including the Galápagos Islands; some species introduced to and naturalized
in the Old World.
Many taxa are cultivated for ornamental
plants
, food, and animal fodder
. Some species of Opuntia become obnoxious weeds
; some species have been planted in Africa for stabilization of sand dunes.
Many interspecific
hybrids are known and have been named; only five are fully treated here; two other named hybrids recognized by the author
are briefly described and cross-referenced under putative parent taxa.[2]
