were recorded in Syria . The subspecie C. spinosa subsp. rupestris was found in seven
locations, mostly in the southern region of the environment, while he found the S
yrian C.
spinosa subsp. spinosa in seventeen of the study sites in Syria. Chemical analysis showed
that, the soils of all location were not salty and pH ranged between (6.9-8.4), Soils texture
was clayey and clay loam in most locations. According dependant on equation of
Emberger, it was found that distribution of subspecies Capparis spinosa were located in a
wide range from bioclimatic very dry to semi- humid zone, through with dry, semi-dry,
