A genus of about 180 species, herbs, of temperate and subtropical areas. The traditional separation of Linum, its component sections, and related genera (Sclerolinum, Hesperolinum, Cliococca) appears to need reworking (McDill et al. 2009; McDill & Simpson 2011; Schneider et al. 2016). Linum could encompass the related genera into an ever more heterogeneous Linum sensu lato, or sections of Linum could be elevated to generic rank (some sections have been previously accorded such rank).
