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 Hylocereus

Shrubs , epiphytic, hemi-epiphytic, or epipetric , straggling, climbing , scandent , or pendent, irregularly many branched. Roots diffuse , often adventitious along stem internodes. Stems segmented , green, blue-green, gray-green, or somewhat whitish with wax; segments elongate , 3-winged or -angled, length highly variable, 10-500+ × [1-]4-7.5[-10] cm, distinctly narrowed proximally, glabrous ; ribs (2-) 3(-5), winglike to narrowly triangular in cross section , rib crests straight to undulate , crenate [toothed , notched , or lobed ], often with a line of hard, brown to gray bark between areoles; areoles (10-) 35-50 mm apart along ribs, oval , short woolly , sometimes subtended by minute, vestigial leaves at growing stem tip; areolar glands inconspicuous; cortex and pith mucilaginous . Spines 0-4[-8] per areole, whitish or yellowish to brownish [blackish or red, aging gray], acicular [awl-shaped or hairlike], straight, terete , generally short, 0-4[-10] mm, hard, bases sometimes conic or swollen, smooth , glabrous; radial and central spines not distinguishable. Flowers nocturnal , lateral to subterminal on 1+-year-old stems, at adaxial edges of areoles, long tubed, funnelform , [3-]25-29[-38] × [8-]15-25[-30] cm; outermost tepals often greenish, yellow, pink, or occasionally purplish red or white, 10-15 × 1-1.5 cm, margins entire; inner tepals white to cream [rarely pinkish or red], 10-15 × 1.5-2.5 cm, margins entire; ovary tuberculate [to smooth], scaly , spineless, usually without hairs or wool; scales triangular, broad, thick conspicuous , to 25 mm; stigma lobes to 24, white. Fruits irregularly dehiscent along 1 side, red [to purple or magenta], oblong to ovoid or spheric, [20-]50-125 × 40-120 mm, fleshy , spineless; pulp white; scales persistent, green, triangular, conspicuous, thick and fleshy, to 4+ cm; floral remnant often persistent . Seeds black, [elongate or] pyriform [to reniform ], 2-3 mm, glossy; testa smooth or minutely textured. x = 11.
