Multivariate analysis of floristic composition at the species level was performed on eleven wadis in Gebel Elba, S.E. Egypt. A total of 377 species, in 74 families and their distribution relationships in 35 floristic elements were subjected to numerical analysis using the un-weighted pair- group average linkage method (UPGMA). The main elements of phytochory, in species numbers, are: Saharo-Sindian 29.5%; Somalia- Masai 17.2%; Sahel 12.1% (mono-, bi-, tri- & pluri-regional). The Saharo-Sindian element of phytochory includes: 25.7%. Saharo-Arabian (SS2); 17.4% Nubo-Sindian (SS3) and 16.2% Sahara regional subzone (SS1). Boreal element (Mediterranean, West Asia, Euras) is represented by only 9.9% of the taxa.
