Abstract

Securidaca longepedunculata Fresen., commonly known as the violet tree, belongs to the family Polygalaceae. It is widely distributed in tropical Africa, Mozambique, as well as in the North- West and Limpopo provinces of South Africa. The Vhavenda people use the roots of this species as an aphrodisiac. The species is co-dominant in the savanna vegetation of the Nylsvley Nature Reserve. This research looked at the ecology of the study species within the Nylsvley Nature Reserve because of its importance there. Understanding the population structure and environmental factors that impact on the species might help in assessing the population in urban areas. The population of the study species in the reserve displayed an adequate growth curve, when looking at its stem circumference and height-size classes. High intensity fires showed a negative effect on individuals of S. longepedunculata. Evidence of animals feeding on the roots at the study species was also recorded in the study.
