A study of flora, ecological and phytogeographic spectra was conducted in the Bélo area of the Conkouati-Douli National Park in Mayombe. To carry out this study a collection of field data was made in 2016, the collected samples were determined and deposited to the national herbarium (IEC). The data analysis identified 575 species and infraspecific taxa divided into 131 families and 353 genera. The families of Rubiaceae, Annonaceae and Fabaceae are the most diverse. The analysis of ecological spectra made it possible to note the predominance of phanerophytes, sarcochores and mesophylls. The analysis of the phytogeographic distribution of the listed species has made it possible to note that our study area fits well into the center of Guinean-Congolese endemism. Two new species for congolense flora were collected: Eurypetalum tessmannii Harms and Podococcus acaulis Hua.

Une étude de la flore, des spectres écologiques et phytogéographiques a été menée dans la zone de Bélo dans le parc national Conkouati-Douli situé dans le Mayombe. Pour réaliser cette étude une collecte des données sur le terrain a été faite en 2016, les échantillons collectés ont été déterminés et déposés à l’herbier national (IEC). L’analyse des données a permis de recenser 575 espèces et taxons infra spécifiques reparties en 131 familles et 353 genres. Les familles des Rubiaceae, Annonaceae et Fabaceae sont les plus diversifiées. L’analyse des spectres écologiques a permis de noter la prédominance des phanérophytes, des sarcochores et des mésophylles. L’analyse de la distribution phytogéographique des espèces recensées a permis de noter que notre zone d’étude s’intègre bien dans le centre d’endémisme guinéo-congolais. Deux espèces nouvelles pour la flore du Congo ont été collectées : Eurypetalum tessmannii Harms et Podococcus acaulis Hua.
