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