Résumé :

This work constitutes a first study on the flora and the vegetation of the intra-forest clearings on hydromorphic soils of the Gabon. It analyzes the floral composition, brings to light the main plant communities and the species which characterize them. An analysis of environmental structural factors Is then realized to characterize these communities. The flora is dominated by Cyperaceae and the vegetation is a watery semi-meadow. Two principal communities are identified. The main factors which influence the flora are the rate water in the ground, the depth of the mud and, in a lesser measure, an animal attendance.
