Composition floristique et structure des formations à Garcinia lucida dans la région de Bipindi-Akom II (Sud-Cameroun)

Abstract

The Bipindi-Akom II region in South-Cameroon belongs to the Biafran atlantic district of the Guineo-congolian domain of dense humid evergreen forests. Inside this vegetation unit, Garcinia lucida is a remarkable understorey gregarious species, growing in low-lying ground and on slope of some hills. Four localities in which this species occurs have been sampled and 36 common species have been identified forming the floristic composition of such plant community. Representative species are, in addition to Garcinia lucida, Treculia obovoidea, Coelocaryon preussii and Raphia regalis. The analysis of the different strata showed that Garcinia lucida is the main dominant species at the shrub layer. No dominant species have been found at the tree layer. The population structure in the four localities indicates the stability of these formation but also the low occurence of emergent trees inside these Garcinia lucida facies.
