Othonna is a genus of evergreen or deciduous geophytes, dwarf succulents or shrubs belonging to the sunflower family Asteraceae. The genus includes more than 100 species concentrated in the Western Cape of South Africa and southern Namibia. A few species occur in summer rainfall parts of southern Africa. The genus is closely allied to Senecio and can be distinguished principally by details of the involucre. Taxonomically they are in need of a modern revision.

Othonna gymnodiscus, synonymously known as Doria gymnodiscus, Doria semicalva, Othonna lingua and Othonna semicalva and commonly known as Leafy Babooncabbage, is a South African endemic species found in the Eastern Cape and Western Cape provinces, ranging from Cederberg to Port Elizabeth. It is a tuberous erect succulent perennial with leathery leaves and yellow daisy flowers that appear in early spring.
