Draba Linnaeus. Draba, Whitlow-grass.
A genus of about 330 species, perennial and annual herbs, of Northern Hemisphere and Andean South America, particularly in arctic and alpine habitats. Molecular phylogenetic studies show that Erophila should be included in Draba, but that other elements are discordant and should be segregated as Abdra and Tomostima (Koch & Al-Shehbaz 2002; Al-Shehbaz 2012; Jordon-Thaden et al. 2010).
