Baikiaea plurijuga, known as African teak, Mukusi, Rhodesian teak, Zambian teak or Zambesi redwood, is a species of legume in the Fabaceae family. The woodland which it dominates is known as Gusu woodland, and is located on the deep, aeolian and fluvial Kalahari Sands which have virtually no clay or silt. These sands provide exceptional growing conditions for deep-rooting trees, but the deficiency in clay restricts tree growth to sites holding nutrients in the form of organic matter. It is found in Angola, Botswana, Namibia, Zambia and Zimbabwe.
