Genera indigenous to southern Africa

Information from Glen (2000).

Juniperus

About 60 species (mainly temperate and subtropical regions of the northern hemisphere). One species, Juniperus procera (African juniper), is native to southern Africa where it is found in the Eastern Highlands of Zimbabwe. In addition, Juniperus virginiana (Red cedar) has become naturalised in the Free State where it invades grassland, river banks and rocky outcrops. The leaves of this species are toxic to livestock and are a skin irritant to humans (Palgrave and Palgrave 2002). An additional 17 species of Juniperus have been cultivated in southern Africa.
