Lasiosiphon rigidus, a new species from the Tankwa Karoo and two new combinations in the genus for South Africa

Thymelaeaceae are well represented in southern Africa, with ± 190 species in nine genera (Bredenkamp & Beyers 2000; Beaumont et al. 2009). Preliminary phylogenetic analyses of nuclear and plastid DNA sequences (Van der Bank et al. 2002; Beaumont et al. 2009) indicate the need for substantial revision in the generic circumscriptions in subfamily Thymelaeoideae.Web of Scienc
