“…The first community (Anahasis setifera -Acacia ehrenbergiana), has not been recognized in previous reports. Nevertheless Anabasis seti-$era was recorded in wadi Gimal (EL-SHARKAWI et al 1982 b) and Acacia ehrenbergiana in wadi Qena (KASSAS & GIRGIS 1972) as well as in wadi Kharit (EL-SHARKAWI et al 1987). The members of this community represent to great extent the vegetation of wadi Gurdi described by KASSAS & GIRGIS (1972).…”

Wadi Quena is one of the major wadis of the Eastern Desert in Egypt. It is unique in its nourth‐south orientation among other wadis in this desert. Phytosociological study of this wadi is based on the analysis of vegetation in 21 stands, using the Zürich Montpellier technique. The vegetation survey indicated the prevailance of perennials in this wadi. Thirty nine species comprising the vegetation of the wadi are segregated in two community types: 1. Anabasis setifera ‐ Acacia ehrenbergiana and 2. Zygophyllum coccineum‐Shouwia thebaica. The second community type has two subcommunities: a. Tamarix nilotica ‐ Artemisia judaica and b. Cotula cinerea ‐ Cleome droserifolia. Elements of the alliance Zygophyllaeion coccini previously recognized in other wadis of this desert are well represented in this wadi. The distribution of the communities recognized in this study seems to be dependent upon the moisture retention properties and on the soil depth.

Vegetation analysis of the Aswan–Allaqi road in the Southern Eastern Desert of Egypt indicates the dominance of Morettia philaeana, Aerva javanica, Fagonia indica, Salsola imbricata, Pulicarica crispa, Crotalaria aegyptiaca, Lotononis platycarpa, Citrullus colocynthis, Pulicaria incisa, Astragalus vogelii and Zygophyllum simplex. Four vegetation clusters are recognized after the application of the Two‐Way Indicator Species Analysis (TWIN‐SPAN). These clusters are named after the dominant species as follows: Fagonia indica – Aerva javanica, Salsola imbricata – Zilla spinosa, Salsola imbricata – Morettia philaeana and Salsola imbricata – Aerva javanica. Among the estimated soil variables in the present study, silt, clay, pH, EC, HCO3, CI−, and Ca2+ are important in characterizing the vegetation clusters.

“…The Toothbrush tree Salvadora persica was recorded among the members of this community type. EL-SHARKAWI et al (1988) identified Moringa peregrina in the eastern tributaries of wadi Qena. Apparently, this plant species have high water requirements, thus indicating richer moisture conditions in the soil in various degrees.…”

Twelve wadis proliferate in the area surveyed drain this part of the Red Sea mountains into the Sea at Qusseir province. Phytosociological study of these wadis is based on the analysis of 55 stands using the Zuarich‐Montpellier technique. The vegetation survey revealed the prevailance of perennials in this area. Two distinct community types are recognized in the stands studied in the investigated wadis, each of which seems to have its own ecological characteristics especially concerning the water factor. The community type dominated by Capparis decidua and Tamarix nilotica covering the deltaic areas and the end parts of the wadis traversing the inland basement complex country. Some members of this community type are halophytic plants. The other community type dominated by Pulicaria undulata and Pulicaria crispa was found inhabiting most of the wadis courses especially the high localities. Members of this community type reflect the prevailing xerophytic conditions. Elements of the alliance Zygophyllaeion coccini previously recognized in other wadis of this desert are well represented in these wadis. Within the area surveyed, the individuals of most species covered in this study exhibit a wide range of variation in size and vitality. These differences are related mainly to differences in water resources.
