Crassothonna capensis is a spreading succulent bearing yellow flowerheads, previously known as Othonna capensis.
The flowerhead in the photo found in Kirstenbosch during November has about a dozen petals and a yellow centre. The plant branches freely and has cylindrical succulent grey leaves.
The distribution of this South African endemic is in the Eastern Cape only, found near the coast as far east as Uitenhage.
The habitat is dry, rocky flats. The species is not considered to be threatened in its habitat early in the twenty first century (Bond and Goldblatt, 1984; www.finegardening.com; http://redlist.sanbi.org).
