Abstract Three sites at each of five localities, in the South Western Region of Saudi Arabia were surveyed during 1992, for their soil physico-chemical properties, and cyanobacterial communities. The soils were moderately calcareous, and characterized as sandy loam textured and alkaline. Electrical conductivity and total soluble salts ranged between 0.196-2.228 mmhos cm -1 and 137.2-1559.6 ppm, respectively. Calcium was the major soluble cation, and sulphate, chloride and bicarobonate were the principal anions. A total of 22 cyanobacterial and algal species were identified from the 15 soil samples following rehydration and culture in different enriched media. The species included 19 cyanobacteria, 2 Chlorophyta and 1 Bacillariophyta. 7 cyanobacteria: Nostoc edphicum, N. muscorum, Phormidium bohneri, P. favcolarum, P. tenue, Pleurocapsa minor and Synechococcus aeruginosus are new records for the Saudi Arabian Flora. en_US
