What is "ingwavuma"

Ingwavuma is a town in the Umkhanyakude District Municipality of KwaZulu-Natal Province, South Africa. It is unclear where the name of the town came from; one theory is that it was named after the Ngwavuma River while another is that there was a leader called Vuma, the name then meaning "Vuma's place" in Zulu. Trees found on the river bank are also named Ngwavuma (Elaeodendron transvaalense or Bushveld Saffron) but it is unclear which entity was named after which (person, river, town or trees). It is over above sea level in the Lebombo Mountains and boasts several highly scenic spots. The town is from the country's border with Swaziland and overlooks the plains of Maputaland to the East. It falls within the Mngomezulu Tribal Authority.
