Four new species are described from central and eastern Angola adjacent NW Zambia. All occur in Kalahari sand savannas rich endemic more widely distributed geoxylic suffrutices. Despite being known very few collections, the conservation status of one these is assessed as Least Concern, grasslands nutrient-poor, remote sparsely populated areas, not threatened with conversion to agriculture. The ...

Abstract The interaction effects between climate and fire regime in controlling the type of vegetation species composition is well established among Earth’s biomes. Climate associated are never stable for long, annual temperatures, atmospheric carbon dioxide oxygen levels, burn probability have varied radically over last 350 million years. At scale thousands years, floras oscillated spreading r...
