Notes

Oxybasis was described by Karelin & Kirilov (1841) and included at that time only one species, O. minutiflora Kar. & Kir. (= Oxybasis chenopodioides (L.) S. Fuentes, Uotila & Borsch). The phylogenetic studies by Fuentes-Bazán & al. (2012b) and Sukhorukov & al. (2013) support the monophyly of this widespread genus as a member of Chenopodieae and enlarge its circumscription with species segregated from Chenopodium s.l. At least ten species are currently known (some recently transferred from Chenopodium: see Mosyakin 2013; Sukhorukov 2014), and some occur in saline habitats.
Since Oxybasis contains O. rubra (L.) S. Fuentes, Uotila & Borsch, and its basionym Chenopodium rubrum L. is considered by some authors a lectotype of Chenopodium, the adoption of that lectotype would result in Oxybasis becoming a synonym of Chenopodium (see there).
