Abstract
The present study aims to assess plant diversity in Hema Faid region at Ha’il province. The result revealed that the study region harbors 199 species of 161 genera distributed over 54 families; one species from pteridophytes (Adiantum capillus-veneris L.), one species from gymnosperms (Ephedra foliata Boiss. ex C.A. Mey) and 197 species from angiosperms. Majority of plants in the region belong to the therophytes group which constitute about 65% of total species recorded in this study. The most species-rich families were Asteraceae (14%), Fabaceae (11%), Poaceae (9%), Brassicaceae (6%), Boraginaceae, Caryophyllaceae, Chenopodiaceae and Zygophyllaceae (4% for each). Also this study revealed that Hema Faid region is more diverse compared with other well-studied phytogeographic regions in Ha’il province. In addition, 34 species were recorded in this study for the first time in Ha’il province. Some species recorded are endemic-endangered in Hema Faid region and others are endangered species to Ha’il province.
