This member of the Cucurbitaceae family was given this name by Joseph Dalton Hooker in 1871. It is found from Senegal to South Africa, growing in a well drained soil with some water and some sun. The large caudex can grow from 25 to 60 centimetres in diameter, the vines reach for two and a half meters. The flowers are tiny and green, the fruits red.
The genera name is derived from two Greek words, trochos; 'a wheel' and meris; 'a part'. The connection to the plant is rather obscure; perhaps the long, narrow corolla lobes look like the spokes of a wheel? The species name for the large fruits.
