Acanthothamnus

	Acanthothamnus ''Acanthothamnus'' is a monotypic genus in the family ''Celastraceae'' which contains only the species ''Acanthothamnus aphyllus''. The genus is sometimes known by the unaccepted synonym ''Scandivepres'' and its natural range spans central Mexico. Taxonomy ''Acanthothamnus'' is most closely related to the genera ''Brexia ''Brexia'' is a plant genus assigned to the Celastraceae. It is a dense evergreen shrub or small tree of usually around 5 m high, with alternately set, simple, leathery leaves with a short leaf stem and lanceolate to inverted egg-shaped l ...'' and '' Canotia''.

	Celastraceae The Celastraceae (staff-vine or bittersweet) are a family of 97 genera and 1,350 species of herbs, vines, shrubs and small trees, belonging to the order Celastrales. The great majority of the genera are tropical, with only ''Celastrus'' (the staff vines), ''Euonymus'' (the spindles) and ''Maytenus'' widespread in temperate climates, and ''Parnassia'' (bog-stars) found in alpine and arctic climates. Of the 97 currently recognized genera of the family Celastraceae, 19 are native to Madagascar and these include at least 57 currently recognized species. Six of these 19 genera ('' Brexiella'', '' Evonymopsis'', '' Hartogiopsis'', ''Polycardia'', ''Ptelidium'', and ''Salvadoropsis'') are endemic to Madagascar. Genera A complete list of the genera is: * ''Acanthothamnus'' * ''Allocassine'' * '' Anthodon'' * '' Apatophyllum'' * ''Apodostigma'' * ''Arnicratea'' * ''Bequaertia'' * '' Brassiantha'' * ''Brexia'' * '' Brexiella'' * '' Campylostemon'' * '' Canotia'' – crucifixion thorn * ...

	Monotypic Taxon In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

	Brexia ''Brexia'' is a plant genus assigned to the Celastraceae. It is a dense evergreen shrub or small tree of usually around 5 m high, with alternately set, simple, leathery leaves with a short leaf stem and lanceolate to inverted egg-shaped leaf blades. The pentamerous flowers occur in cymes. The petals are greenish white, the samens are alternating with wide, incised staminodes. The superior ovary develops in a long ribbed fruit. ''Brexia'' naturally grows on the coast of East Africa, on Madagascar, the Comoros and Seychelles. Opinions differ about the number of species in ''Brexia''. Sometimes the genus is regarded monotypic, ''B. madagascariensis'' being a species with a large variability, but other authors distinguish as many as twelve species. Common names for ''B. madagascariensis'' include jobiapototra, tsimiranjana, tsivavena, vahilava, voalava, voankatanana, voantalanina, voatalanina and votalanina (all Malagasy), and mfukufuku ( Swahili), mfurugudu ( Shambala, Tanza ...

	Canotia ''Canotia holacantha'', also known as crucifixion thorn or simply canotia, is a flowering shrub / small tree in the family Celastraceae. It is the only species in the genus ''Canotia''. Distribution The plant is native to the higher elevation deserts of the Southwestern United States in Arizona and southeastern California, and of Northwest Mexico in isolated locales in Baja California and Sonora). Canotia grows in desert scrub environments, primarily on slopes or in washes. It is found in the higher Sonoran Desert across central Arizona, reaching to the Mojave Desert of California and northwest Arizona, and into the lower reaches of the Grand Canyon. Prehistory The prehistoric distribution of ''Canotia holacantha'' has been analyzed with pollen records in certain locations. One of the most detailed studies has been conducted in the Waterman Mountains of Arizona, where ''C. holacantha'' has been documented to have occurred during the Late Wisconsin glacial period, along with domi ...

	Celastrales Genera The Celastrales are an order of flowering plants found throughout the tropics and subtropics, with only a few species extending far into the temperate regions. The 1200"Lepidobotryaceae", "Parnassiaceae", and "Celastraceae" In: Klaus Kubitzki (ed.). ''The Families and Genera of Vascular Plants'' vol. VI. Springer-Verlag: Berlin;Heidelberg, Germany. (2004). (vol. VI). to 1350Peter F. Stevens (2001 onwards)CelastralesAtaMissouri Botanical Garden/ref> species are in about 100 genera. All but seven of these genera are in the large family Celastraceae. Until recently, the composition of the order and its division into families varied greatly from one author to another. Description The Celastrales are a diverse order that has no conspicuous distinguishing characteristic, so is consequently hard to recognize. The flowers are usually small with a conspicuous nectary disk. The stipules are small or rarely absent. The micropyle has two openings and is therefore called a bistomal microp ...
