=== Phylogeny of Asphodeloideae ===

There is agreement among many researchers that Asphodeloideae can be further divided into a [[monophyly|monophyletic]] group comprising ''Aloe'' and its immediate relatives, and a nonmonophyletic group of the remaining genera.<ref name=Chase2000/><ref name=Smith1991>{{cite journal|last=Smith|first=G.

(Alternatively, it may be treated as the subfamily Alooideae within a more narrowly circumscribed family Asphodelaceae.)<ref name=apwebAsphodeloideae/> Aloeae are mainly [[rosette (botany)|rosulate]]d-leaf [[succulents]], while the other genera are not succulent.  The genera in Aloeae are centered in southern [[Africa]], while the other genera have mainly a [[Eurasia]]n distribution.<ref name=Treutlein2002/>
