Vegetation of inland desert wadies in Egypt

Wadi Abu Ghusun is one of the several wadies dissecting the southern part of the eastern desert and oriented with its delta to the Red Sea. The vegetation is much rich and some of the alliance ( Acacia raddiana and Lycium shawaii ) are trees or shrubs. This is newly recorded for the Egyptian desert. Four communities were identified according to the physiographic factors which seem to be the determining factors of the vegetation. These communities are: alliance of Zygophyllum simplex , association of Zygophyllum coccineum – Ochradenus baccatus , association of Stipagrostis plumosa – Forsskalea tenacissima , and association of Aristida funiculata–Lotus deserti .
