Sebaea natalensis is a perennial or biennial branching from the base and reaching heights around 30 cm. The stalkless leaves have rounded or pointed tips and are eared at the base. They become about 13 mm long and 15 mm wide.
The yellow flowers appear in dense, flat-topped inflorescences. The twisted buds are ridged along the sepal keels, the calyx later straw-like. The five broad petals spread above a short tube, their tips rounded or obtusely pointed. The anthers end in glands. Flowering happens from late spring to after midautumn.
The species distribution is in the east of South Africa, from the Eastern Cape through the eastern Free State and KwaZulu-Natal to Mpumalanga. The photo was taken near the Sani Pass.
The habitat is moist grasslands and marshes to heights up to 2100 m. The habitat population is deemed of least concern early in the twenty first century (Pooley, 1998; iNaturalist; https://www.selinawamucii.com; https://www.worldfloraonline.org; http://redlist.sanbi.org).
