A revision of the genus Anginon (Apiaceae)

Anginon, a hitherto poorly known genus of woody Apiaceae endemic to southern Africa, is revised. Field studies over several years have shown that 12 species can be recognised, of which five are newly described: A. ternatum, A. fruticosum, A. pumilum, A. tenuior and A. intermedium. The new combination A. streyi is made to transfer Sonderina streyi to Anginon, with which it shares the woody habit and heavily cutinised outer cell walls of the fruit epidermis. A formal taxonomic treatment is presented, including a key to the species, correct nomenclature, typification, descriptions and distribution maps.
