Abstract

This work constitutes the synthesis of an analysis of the Poaceae weed flora of Senegal. It reviews the inventory of Poaceae of the weed flora of different agro-ecological zones and of different crops. An analysis of the inventory data was carried out and the results gave indications on the taxonomic and chorological spectrum. The results identified 121 species in 51 genera of Poaceae considered as crop weeds. Eleven genera represent the dominant genera in this flora. Therophytes and hemicryptophytes are the more numerous, followed by champhytes, phanerophytes, geophytes, hydrophytes, halophytes and helophytes. Pantropical, African and Afro-Asian species represent the majority of Poaceae worldwide. In Africa, species with Sudan-Zambezian and Guinean-Congolese-Sudan-Zambezian affinities are the most represented, showing the tropical character of this grass flora.
