Summary
Included here is the African biozone that extends from the mouth of the Limpopa River to Port Elizabeth. In the north it stretches inland for some 240 km but further south where the mountains come close to the sea its inland boundary is no more than about 8 km from the sea.
Of the endemic and near endemic vascular plants so far recorded there are about 272 species in 183 genera and 74 families. There are 13 endemic genera (marked red) and 2 endemic families (Rhynchocalycaceae and Strangeriaceae) and the families Bruniaceae and Penaeaceae are restricted to South Africa. The genera Atalaya and Protorhus have an interesting distribution. They occur nowhere else in Africa but outside Africa occur in Asia and Madagascar.
