This member of the Asteraceae family was given this name by Augustin Pyramus de Candolle in 1838. It is found around Kamieskroon and Holrivier (between Springbok and Clanwilliam) in north-western South Africa, growing in a well drained sandy soil with some water and quite some sun. The caudex can grow to four centimetres in diameter, the entire plant to from 20 to 50 centimetres in height. The flowers are bright purple.
The genera name from the Greek othone, 'a linen cloth or napkin', in allusion to the downy covering of some of the earlier known species. The species name for the shape of the leaves, "looking like Cakile " a member of the Cruciferae family. I think this is a winter-grower. A small plant by Jean Andre Audissou, Inaturalist.org.
