Cyanella lutea, in Afrikaans the geelraaptol (yellow turnip top), is a perennial herb growing from a corm. The narrow, lance-shaped leaves usually form a spreading rosette on the ground.
The flower stem reaches 25 cm, producing a raceme of yellow flowers (sometimes pink); each comprising six tepals. Flowering happens in late spring.
The distribution is wide, in the north from Namibia, Botswana and Lesotho southwards across the Karoo to the Little Karoo. The habitat varies, mainly on clay or limestone flats in winter, summer and all year rainfall areas.
