Abstract

A taxonomic revision is presented for the two geophytic species of Othonna L. (Asteraceae: Senecioneae: Othonninae) distinguished by a condensed caudex without evident internodes. These species are morphologically and phylogenetically distinct from the remaining geophytic species. This account includes descriptions, complete nomenclature and typification, illustrations and geographical distribution. We recognise the following two species: O. auriculifolia with radiate capitula and mature pappus 3–25 mm long, and O. taraxacoides (DC.) Sch. Bip. with disciform capitula and mature pappus 3–8 mm long. Both species are vegetatively variable.

期刊介绍： Bothalia: African Biodiversity & Conservation is published by AOSIS for the South African National Biodiversity Institute (SANBI) and aims to disseminate knowledge, information and innovative approaches that promote and enhance the wise use and management of biodiversity in order to sustain the systems and species that support and benefit the people of Africa. The journal was previously published as Bothalia, and had served the South African botanical community since 1921. However the expanded mandate of SANBI necessitated a broader scope for the journal, and in 2014, the subtitle, African Biodiversity & Conservation was added to reflect this change.
