| Abstract: | Othonna cerarioides Magoswana and J.C. Manning is described as a new species from Namaqualand, Northern Cape Province of South Africa. It is an erect shrub with rod-like stems and branches, bearing numerous spur-shoots with obovate-oblanceolate leaves clustered at the tips, and up to nine disciform capitula per spur-shoot. Othonna cerarioides is anomalous in the genus in that the style of some of the disc florets is bifid. Othonna is diagnosed within subtribe Othonnineae by female-sterile disc florets with simple (or very rarely minutely bifid) styles. The disc florets in the closely related genus Hertia are bisexual with well branched styles. |
