| Abstract | ||||
| W adi Arar in the northern region of Saudi Arabia is one of the most important Wadis of the Kingdom. The present study provides an analysis of vegetation types, life forms, as well as floristic categories and species distribution. A total of 194 species representing 30 families of vascular plants were recorded. Compositae, Gramineae and Leguminosae were the most common recorded families. Therophytes and Chamaephytes are the most frequent life forms, indicating typical desert spectrum vegetation. The distribution of species in the different sectors of the Wadi as well as the phytochoria for the recorded species is provided. Eighty nine species (45.88%) are typically bi-regional. Furthermore, about 105 species (53.5%) are mono- and pluriregional taxa. The highest number of species (135 or 69.59%) was recorded for annual plants, while the lowest number of species (59 or 30.41%) was recorded for perennial, short perennial or annual to biennial species. | ||||
