This study aims to investigate the floristic composition, biological spectrum, chorological affinities, and describes the vegetation inhabiting the main channel and the deltaic part of Wadi Kid as one of the principal coastal wadis in South Sinai. The life-form spectrum in the present study is characteristic of an arid desert region with the dominance of therophytes (30.43% of the total) and chamaephtyes (26.09%), followed by hemicryptophytes (26.09%), phanerophytes (14.49%), geophytes (1.45%) and parasites (1.45%). Phytogeographically, the Saharo-Arabian element forms the major component of the floristic structure. The investigation revealed that Wadi. Kid is potential shelters of 5 vegetation groups. Detrended Correspondence Analysis (DCA) represented the distribution of the recognized groups along the first two axes. Canonical Correspondence Analysis (CCA) indicated that clay, coarse sand, electric conductivity, chlorides, magnesium and calcium were the main soil parameters which determined the distribution of vegetation in the study area.
