Editing Aloe (section)

==Systematics==

The [[APG IV system]] (2016) places the genus in the family [[Asphodelaceae]], subfamily [[Asphodeloideae]].<ref name=APweb/> In the past it has also been assigned to the families [[Liliaceae]] and Aloeaceae, as well as the family Asphodelaceae [[sensu stricto]], before this was merged into the Asphodelaceae [[sensu lato]].

The [[circumscription (taxonomy)|circumscription]] of the genus has varied widely. Many genera, such as ''Lomatophyllum'',<ref name="WCSP_280369">{{cite web |title=''Lomatophyllum'' |work=World Checklist of Selected Plant Families |publisher=[[Royal Botanic Gardens, Kew]] |url=http://apps.kew.org/wcsp/namedetail.do?name_id=280369 |access-date=2013-02-25}}</ref> have been brought into [[synonym (taxonomy)|synonymy]]. Species at one time placed in ''Aloe'', such as ''[[Agave americana]]'', have been moved to other genera.<ref name="WCSP_297041">{{cite web |title=''Aloe americana'' |work=World Checklist of Selected Plant Families |publisher=[[Royal Botanic Gardens, Kew]] |url=http://apps.kew.org/wcsp/namedetail.do?name_id=297041 |access-date=2013-02-25}}</ref> [[Molecular phylogenetics|Molecular phylogenetic studies]], particularly from 2010 onwards, suggested that as then circumscribed, ''Aloe'' was not [[Monophyly|monophyletic]] and should be divided into more tightly defined genera. In 2014, [[John Charles Manning]] and coworkers produced a phylogeny in which ''Aloe'' was divided into six genera: ''[[Aloidendron]]'', ''[[Kumara (plant)|Kumara]]'', ''[[Aloiampelos]]'', ''Aloe'', ''[[Aristaloe]]'' and ''[[Gonialoe]]''.<ref name=MannBoatDaruMaur14/>

In addition to the species and hybrids between species within the genus, several hybrids with other genera have been created in cultivation, such as between ''Aloe'' and ''[[Gasteria]]'' ([[× Gasteraloe|× ''Gasteraloe'']]), and between ''Aloe'' and ''[[Astroloba]]'' (''[[×Aloloba]]'').
