Abstract
Abstract P. biglobosa, known as néré or the shea butter tree, is an important multipurpose tree in tropical and subtropical Africa, particularly valued for food uses. It occurs naturally in Africa between 15°N and 0°N in a strip extending from the Atlantic to the Indian Ocean across Mali and Chad, to Cameroon, Sudan and Uganda, as well as in the Central African Republic. The natural phytogeographical distribution of Parkia biglobosa corresponds to the "Sudanian Regional Centre of Endemism" and the "Guineo-Congolia/Sudania Regional Transition Zone" (White, 1983). The species is often found with Vitellaria paradoxa in cultivated parklands near villages with short fallows. In most cases, P. biglobosa has been conserved from land clearing, it is rarely planted. In savanna woodland, P. biglobosa occurs with Pterocarpus erinaceus, Khaya senegalensis, Daniellia oliveri, Afzelia africana, Prosopis africana etc.
