Axyris, Sp. Pl. 1: 979. 1753 sec. Kühn (1993)
- Type: Axyris amaranthoides
Axyris, together with Krascheninnikovia and Ceratocarpus, constitutes the Axyrideae G. Kadereit & Sukhor. (Kadereit & al. 2010). The genus consists of six species mainly concentrated in the mountains of Central Asia and eastern Siberia (Sukhorukov 2011); some species (especially A. amaranthoides L.) occur as alien weeds in Eurasia and North America beyond their native range. Investigated species of the genus show heterocarpy (Sukhorukov 2005, 2011).
