Bryophyta (Mosses) of Senegal: the case of Mosses in Herbaria and databases

In Senegal, Mosses constitute a large and diverse systematic group. This work is a contribution to the knowledge of Bryophyta in the herbaria of Senegal. It specifically proposes to determine the structure of the Bryophyta on the prospected sites in order to provide basic knowledge for a better sustainable management. This study is carried out in the first place in the herbaria of the University Cheikh Anta Diop of Dakar/Senegal: the herbarium of the Institut Fondamental d'Afrique Noire Cheikh Anta Diop (IFAN) and the herbarium DAKAR of the Department of Plant Biology of the Faculty of Sciences and Techniques. Secondly, a consultation of different checklists and databases was conducted to collect more information. This research work on the flora of the mosses allowed us to identify a total of 70 species divided into 44 genera, 24 families and 12 orders. The orders Hypnales, Dicranales and Hookeriales are the most represented. Bryaceae are dominant followed by Pottiaceae, Calymperaceae, Dicranaceae and Hypnaceae. The genera Fissidens, Calymperes, Bryum, Gemmabruym and Leucoloma are more diversified. These results are important for the conservation of the environment and the enhancement of plant biodiversity in Senegal.
