Abstract
As part of a vegetation survey programme for nature conservation areas in South Africa, a survey of the plant communities of the mesic calcareous bottomland clays in the Manyeleti Game Reserve was undertaken. The Eucleo divinori — Acacietum nigricentis, a new association, is restricted to these soils. From a Braun-Blanquet analysis of the vegetation, two new subassociations, each with two variants, were identified and described. A quantitative assessment of the woody component of each syntaxon is presented. Ordinations based on the floristic and habitat data revealed the position of the syntaxa on an environmental gradient.
