TL;DR: Phylogenetic analyses for 72 accessions representing 72% of the subtribe indicate that several of the genera are not monophyletic as currently circumscribed, and Pentzia remains paraphyletic by the inclusion of at least Rennera and possibly also Cymbopappus and Marasmodes.
TL;DR: After a careful taxonomic study of additional material, including the first species described by A. P. de Candolle, it is concluded that eight collections should be considered as new species of the genus Marasmodes.
TL;DR: Two new species of Asteraceae from the Cape Floristic Region of South Africa are described, one of which is a local endemic from the lowlands between Piketberg and the Olifants River Mountains and the other a well-collected limestone fynbos endemic.
