La Flore Ptéridologique de Quelques Endroits Humides de la Région de Kédougou (Sénégal)

Mingou Paterne, Gueye Mathieu

Abstract


The study of the Pteridophyte flora of some wetlands in the Kedougou region of the Senegal Republic is the subject of this study. This analysis is based on the herbarium material of the pteridological flora harvested in this region and preserved in the herbaria of various institutions of IFAN, Dakar and Paris (P) also on the bibliographic data. This leads to a field mission to re-evaluate pteridophyte flora in this region. The results obtained show that the diversity of pteridophyte in the region of Kedougou is 11 species except for the very young species whose identification could not be made. These species grouped into 7 genera belong to 5 families of which the best represented are the Pteridaceae with 4 species. All the harvested and identified species were encountered in the Herbarium visited. Thus, in order to facilitate access to their identification, it is necessary to propose the tool which means that the document conforms to the identification key on the paper and the vegetative characters have been favored. Most of the pteridophyte were harvested at the Dindefelo cascade with an abundance of the species Adiantum philippense L. which is a species with large distribution because it is found in almost all the prospected places. All of these species are restricted to wetlands and shaded areas with occupation of all habitats (terrestrial, aquatic, saxicolous and epiphytic).
