Notes

Monotypic genus from North America which is probably phylogenetically nested within Dysphania (Dysphanieae; G. Kadereit, unpubl. data). The widespread genus Dysphania comprises c. 50 species native mostly to South America (sect. Adenois), Eurasia and Africa (sect. Botryoides), and Australia (sect. Dysphania, sect. Orthospora, and sect. Tetrasepalae). Traditionally, only native Australian taxa were included in Dysphania (Scott 1978; Wilson 1983, 1984); later an expanded circumscription of the genus was proposed (Mosyakin & Clemants 2002, 2008) based on morphological evidence. Further molecular phylogenetic studies (Kadereit & al. 2003, 2010; Fuentes-Bazán & al. 2012a-b) demonstrated that Dysphania is phylogenetically distant from Chenopodium and forms the tribe Dysphanieae together with the closely related Suckleya and Teloxys. The latter was included into Dysphania based on morphology (Mosyakin & Clemants 2002, 2008; Clemants & Mosyakin 2003; Zhu & al. 2003) but should be recognized as a separate genus based on molecular results (Kadereit & al. 2010; Fuentes-Bazán & al. 2012a-b).
