The evergreen, pointed leaves of Carissa bispinosa, this plant previously known as C. haematocarpa, have entire, hard margins. Sometimes hairy, the leaves tend to be shiny. There may be a bristle-tip present on the leaf.
The petiole becomes up to 3 mm long. The leaves are opposite and have no stipules or the spines are in their place. After some botanical consolidation of Carissa, only four species are upheld in South Africa for the genus, hence the change (Vlok and Schutte-Vlok, 2015; Coates Palgrave, 2002; http://redlist.sanbi.org).
