Abstract

The present study deals with the floristic analysis of the Plain and coastal area of Abyan governorate. The present study reveals the presence of 266 species belonging to 179 genera and 68 families of vascular plants have been recorded. Based on species contribution, Poaceae, Asteraceae, Mimosaceae, Fabaceae, Malvaceae, Solanaceae, Capparaceae, Euphorbiaceae, Caesalpinaceae, Amaranthaceae, and Asclepidiacea, were found as dominant families. Life-forms in order of importance were Hemicryptophytes (25.93%), Chamaephytes (24.81%), Therophytes (24.43%), and Phanerophytes (21.05%), while the least frequent life form class was Geophytes (3.38%), and Epiphytes (0.37%). The proportion of plant life forms in the study area is very close, indicating that the study area is predominantly desert in nature. The large spread of Acacia sp. shrubs indicates the desert climate in the study area
