The genera of plants within the tribe Stapeliae are all to varying degrees stem succulents.
 Many of the species resemble cacti, though are not closely related, as an example of convergent evolution.
 The stems are often angular, mostly four-angled in cross-section, but in some species there are six or more, with some species of "Hoodia" having more than thirty angles.
 In size they vary from less than 2.5 cm/1" in length to over 2 m/6" tall.
 The leaves are in most species reduced to rudiments, sometimes hardened and thorn-like, arranged on bumps or tubercles on the angles.
 Some species, however, still have recognisable leaves, most notably the Indian species "Frerea indica", and some members of "Tridentea".
 Stapeliads are most abundant in warm, dry climates.
 In Africa, there are two separate regions where Stapeliads have most diversified: northeast Africa, and Southern Africa.
 Several species are endemic to the small island of Socotra off the Horn of Africa.
 The Arabian Peninsula, and most specifically the country of Yemen, contain another concentration of species.
 Several more are found in the drier parts of Pakistan, Afghanistan, India, Nepal, and Myanmar.
 A single species, "Caralluma europea" is found in Europe, in the very southern part of the Iberian peninsula.
 Stapeliads are often regarded as a climax group within the family because of their often structurally complex flowers. Certain aspects of these reproductive parts mirror the pollination systems in the Orchid family and represent a case of parallel evolution though both groups are quite unrelated and have developed similar, though not identical means to achieve the ultimate goal of pollination and therefore reproduction.
 Most stapeliads use flies as pollinators, that are attracted to odours resembling dung or rotting meat, emanating from the flowers.
 Many of the flowers also bear some physical resemblance to rotting animal carcasses, leading to their popular name of Carrion Flowers.
 However, not all stapeliads smell bad, or attract flies.
 Some species use beetles, bees, wasps, butterflies or moths as pollinators.
 Stapeliad flowers range in size from mere millimetres in species of "Echidnopsis" and "Pseudolithos" to those of "Stapelia gigantea" that can reach 40 cm/16" in diameter, and are some the largest of flowers to be found on any species of succulent.
Aciphylla is a genus of about 40 species of plants in the Apiaceae family, endemic to New Zealand and Australia.
 They generally grow as tall spikes surrounded by rosettes of stiff, pointed leaves.
 Some species are known as Spaniard Grass.
Hoodia (known locally as "ghaap" or "bobbejaanghaap") is a genus of flowering plants in the family Apocynaceae, under the subfamily Asclepiadoideae, native to Southern Africa.
At least seven monkey species are native to Central America.
 An eighth species, the Coiba Island howler ("Alouatta coibensis") is often recognized, but some authorities treat it as a subspecies of the mantled howler, ("A. palliata").
 A ninth species, the black-headed spider monkey ("Ateles fusciceps")is also often recognized, but some authorities regard it as a subspecies of Geoffroy's spider monkey ("A. geoffroyi").
 Taxonomically, all Central American monkey species are classified as New World monkeys, and they belong to four families.
 Five species belong to the family Atelidae, which includes the howler monkeys, spider monkeys, woolly monkeys and muriquis. Two species belong to the family Cebidae, the family that includes the capuchin monkeys and squirrel monkeys.
 One species each belongs to the night monkey family, Aotidae, and the tamarin and marmoset family, Callitrichidae.
Hoodia triebneri is a species of plant in the Apocynaceae family.
 It is endemic to Namibia.
 Its natural habitat is rocky areas, especially underneath "Acacia" trees and below ridges.
At least six monkey species are native to Panama.
 A seventh species, the Coiba Island howler ("Alouatta coibensis") is often recognized, but some authors treat it as a subspecies of the mantled howler, ("A. palliata").
 An eighth species, the black-headed spider monkey is also often recognized, but some authorities regard it as a subspecies of Geoffroy's spider monkey.
 All Panamanian monkey species are classified taxonomically as New World monkeys, and they belong to four families.
 The Coiba Island howler, mantled howler, black-headed spider monkey and Geoffroy's spider monkey all belong to the family Atelidae.
 The white-headed capuchin and Central American squirrel monkey belong to the family Cebidae.
 the family that includes the capuchin monkeys and squirrel monkeys.
 The Panamanian night monkey belongs to the family Aotidae, and Geoffroy's tamarin belongs to the family Callitrichidae.
Ocotea aciphylla is a species of Ocotea in the Lauraceae plant family.
 It forms a tree 12-18 m tall.
 It has small hermaphrodite flowers of 3-4 mm long.
 It is found in the Amazon river basin mostly to 1200 m.
Hoodia juttae is a species of plant in the Apocynaceae family.
 It is endemic to Namibia.
 Its natural habitats are rocky areas and cold desert.
 "H. juttae" is found around the Little and Great Karas mountains.
 It is threatened by collection.
 The plant was discovered by Jutta Dinter, the wife of botanist, Kurt Dinter in 1913.
 The scientific name refers to Jutta.
Hoodia ruschii is a species of plant in the Apocynaceae family.
 It is endemic to Namibia.
 Its natural habitats are rocky areas and cold desert.
The genus Huernia (family Apocynaceae, subfamily Asclepiadoideae) consists of stem succulents from Eastern and Southern Africa, first described as a genus in 1810.
 The flowers are five-lobed, usually somewhat more funnel- or bell-shaped than in the closely related genus "Stapelia", and often striped vividly in contrasting colours or tones, some glossy, others matt and wrinkled depending on the species concerned.
 To pollinate, the flowers attract flies by emitting a scent similar to that of carrion.
 The genus is considered close to the genera "Stapelia" and "Hoodia".
 The name is in honour of Justin Heurnius (1587–1652) a Dutch missionary who is reputed to have been the first collector of South African Cape plants.
 His name was actually mis-spelt by the collector.
