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.
