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

Trees or shrubs , erect to trailing , usually many branched, sometimes forming clumps or mats; trunk , when present, initially segmented , 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 GalÃ¡pagos 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]
