Abstract

MAGOSWANA, Simon Luvo; STEPHEN BOATWRIGHT, J.; MAGEE, Anthony R.  and  MANNING, John C.. A taxonomic revision of the Othonna auriculifolia Less. group (Asteraceae: Senecioneae: Othonninae). Bothalia (Online) [online]. 2022, vol.52, n.1, pp.1-9. ISSN 2311-9284.  http://dx.doi.org/10.38201/btha.abc.v52.i1.5.

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 phylogenet-ically 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.

Keywords : geophytes; Othonna auriculifolia; O. taraxacoides; nomenclature; southern Africa; synonyms; succulent.
