The bushwillows or combretums, is a genus of the Combretaceae family. The genus comprises about 370 species of trees and shrubs. Though somewhat reminiscent of willows (Salix) in their habitats, they are not particularly close relatives of these. Bushwillow trees often are important plants in their habitat. Savannahs in Africa, in particular those growing on granitic soils, are often dominated by Combretum and its close relative Terminalia. Other species of this genus are a major component of Southwestern Amazonian moist forests. This genus contains several species that are pollinated by mammals other than bats, which is quite rare indeed. But most species are more conventionally pollinated by insects or birds. Several species are used in African or Indian traditional medicine. Combretastatins, found in the South African Bushwillow, Combretum caffrum, and presumably other species of this genus, are under study for the therapy of tumours, including anaplastic thyroid cancer for which there is little or no approved treatment at present. At least Combretum molle is also recorded to contain large quantities of punicalagins, the antioxidants well-known from the Pomegranate (Punica granatum), a somewhat related plant. These chemicals, too, are suspected to suppress cancer growth.

Combretum mkuzense or Mkuze Bushwillow as it is commonly known is a South African indigenous species from Northern KwaZulu-Natal, Maputaland, eastern foothills of the Lebombo Mountains and Mozambique. It is a scrambling spreading multi-stemmed shrub or small tree up to 4 meters tall. It has pale yellowish flaking bark and elliptic leaves. It bears pale green flowers in spikes during spring. These are followed by large brown 4-winged fruits.
