Cyphostemma is genus of flowering plants belonging to the Vitaceae family. They are caudiciform succulent plants and used to belong to the genus Cissus. The genus name comes from the Greek words kyphos, which means hump, and stemma, meaning garland. Within the Vitaceae family, Cyphostemma is most closely related to Cayratia and Tetrastigma. It consists of several species that are native to Madagascar, Namibia, Botswana, Zimbabwe and South Africa. Some of the plants within this genus are small shrubs while others are considered small trees. They generally have very thick trunks. Larger species can tolerate frost, but small and developing plants should be kept in temperatures above 4°C. They make excellent potted plants for protected patios and in frost free areas are amazing rockery plants.

Cyphostemma seitzianum is also known as Cissus seitziana. This species hails from Central Namibia and grows to a height of 50cm with a width of 70cm.
