Umncumuba

Umncumuba is a Xhosa name recorded for the Tarka River, a tributary of the Great Fish River in the southern African interior. The name is associated with the willow tree, while Tarka itself is of Khoekhoe origin. The river runs through the country north of the Great Fish before joining it below Cradock. Its waters form part of a river system that continues southeast through the Cape's eastern country to the Indian Ocean.
