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]
