Angiosperms of Senegal: Determination Key and Diversity of Families of the Class Monocotyledons

Abstract

The Angiosperms represent the best known and most diverse group in Senegal. Even though a lot of work has been done to gain a good knowledge of this group, more work remains to be done. The main objective of this work is to contribute to a better knowledge of the class of monocotyledons in Senegal. More specifically, this work seeks to propose a determination key for the families of this class in order to facilitate their identification. Based on bibliographical research, a rough table and a summary table listing the different characters of the vegetative and reproductive systems of the Monocotyledonous family of Senegal were drawn up. These tables made it possible to propose dichotomous keys. This study showed that in the flora of Senegal, the Monocotyledons are distributed in 230 genera and 37 families. This work made it possible to propose determination keys essentially based on the stable characters of the vegetative and reproductive systems of these families.
