This member of the Vitaceae family was given this name by Bernard M. Descoings in 1967. It is found in Kenya, growing along rivers in a rather rich soil with some to plenty of water and some sun. The caudex can grow to 25 centimetres or more in diameter, the vines can reach four metres or more. The flowers are creamy green.
The genera name from the Greek kyphos; 'tumor' or 'hump' and stemma; 'garland' or 'crown'. The species name means it is from Neiri - now Nyeri.
