Krascheninnikovia in Novi Comment. Acad. Sci. Imp. Petrop. 16: 551. 1772, nom. cons., sec. Kühn 1993
Krascheninnikovia, according to a molecular study (ITS phylogeny only) by Heklau & Röser (2008), comprises only one widespread and highly polymorphic species with two subspecies (Eurasian and North American ones). However, considerable morphological diversity and wide geographical distribution (from southern Europe through Central Asia to southwestern and western-central North America) of respresentatives of the genus suggest recognition of several species and/or subspecies (Grubov 1966; Zhu & al. 2003). The genus belongs to the Axyrideae (Kadereit & al. 2010).
