context_page_description: Camphorosmeae is a species-rich tribe of the Amaranthaceae, formerly Chenopodiaceae, with 20 genera and about 179 species. It is classified as a single tribe of subfamily Camphorosmoideae.
context_section_description: The taxon "Camphorosmeae" has been published in 1837 by Stephan Ladislaus Endlicher as a subtribe within the Chenopodieae. Alfred Moquin-Tandon classified it as a tribe in 1840, and A J Scott raised it to subfamily level as "Camphorosmoideae" in 1978.
  Phylogenetic research by Kadereit & Freitag (2011) revealed that the traditional classification of the group did not reflect evolutionary relationships. Most of the genera, especially Kochia and Bassia, were found to be highly polyphyletic, so some of their species had to be transferred to spearate genera: Eokochia, Spirobassia, Grubovia and Sedobassia.
  The Australian species of Camphorosmeae form a relatively young group still in the process of speciation and with some hybridization between species. In phylogenetic research by Cabrera et al. (2009), the genera were not clearly separated. Probably Neobassia, Threlkeldia and Osteocarpum should be included in Sclerolaena. Likewise, Enchylaena should be included in Maireana. The species-rich genera Sclerolaena and Maireana were found to be polyphyletic, so that further investigations are needed.
