This cosmopolitan species has a range from Arabia to South Africa and onto some islands in the Indian Ocean. A climber, this species has thin round stems and succulent green leaves that are ovate. This species forms large splays of vines, covering bushes and trees in habitat. These plants came from material collected west of Hajja, Yemen (WY 1134) and are significantly different from the forms of C. rotundifolia common on the African continent. These plants are rooted cuttings in 5-inch pots.
