This member of the Asclepiadaceae family was given this name by Peter Vincent Bruyns in 2017. It is found in Eswatini and north-eastern South Africa, growing in a sandy or other well drained soil with some water and some sun. The caudex can grow from two to five centimetres in diameter, the entire plant to five or even twenty centimetres in height. The flowers are brown and green.

The genera name is from the Greek word keropegion meaning 'candelabrum', because Linnaeus thought that the flowers looked like candles. The species name after the South African Botanist Codd Leslie Edward Wostall, 1908-1999, former director of the Botanical Research Institute, Pretoria.
