Abstract

Vegetation analysis and plants diversity were examined in 4 (sites) directions (East - South - North -West) of Jabal Al-Baddiea, 44 quadrats covering various geomorphological land forms and eight edaphic variables. The flora consisted of 186 taxa (includes species and subspecies) belonging to 131 genera and 45 families. Among the 182 Angiosperm species, Dicots constitute159, Monocos23, while Pteridophytes represented by 4 species. Asteraceae (15 genera, 19 taxa), Apocynaceae (10 genera, 13 taxa), Acanthaceae (9 genera, 13 taxa) Fabaceae (7 genera, 16 taxa), and Euphorbiaceae (6 genera, 10 taxa) were the most common families. The vegetation analysis were dominated by: Adenium obesum, Boerhavia diffusa, Buddleja polystachya Cenchrus ciliaris, Cenchrus longisetus, Cynodon dactylon, Dracaena hanningtonii Euphorbia cactus, Euphorbia inarticulata, Euphorbia granulate, Hypoestes forsskalii, Indigofera spinosa, Justicia flava and Justicia odora.The chemical characters of soils at the different sites were more or less similar with little effect on the distribution of plant species.
