Abstract

This survey was conducted to identify of flora of Zubaid area, Al-Dhalea District, AL- Dhalea Governorate, Yemen. The study area locates between longitudes 44.36'0 - 45.15'0 East and latitudes 14.24'0 - 13.24'0 North. This study was carried out during August 2018 to July 2019 through daily and weekly field trips to nearby areas and monthly. During the survey, 31 sites were selected from the study area based on topographic variety (mountains - plains - valleys), density and plant varieties. As it was recorded (170) plants' species belonging to (115) genera belonging to 44 plant families, of which (one plant species) belonged to fern (Pteridophyte ,non-flowering) plants, and 169 plant species belongs to Angiosperms, of which (151 species) followed Dicotyledons and (18 species) followed Monocotyledonous. The results showed that the most diverse and representative plant families is the" Fabaceae "(18 species, and 8 genera). " Asteraceae "(15 species, 13 genera), Apocynaceae(13 species, and 12 genera).   and the least diverse plant family follows is the The results showed that the most diverse genera are Euphorbia, Acacia, 7 species each one. For the life- form, the results showed that the " Chamaephytes " were prevalent in the study area (72 sp., 42.35%), that was followed by Phanerophytes (41 sp., 24.12%), then the Therophytes (38 sp., 22.35%), that was followed by Hemicryptophytes (11 sp., 6.47%) and Geophytes (7 sp., 4.12%) Finally, the Parasitic plants (one sp. ,0.59%). The results showed that the area of study is rich with plant species and that is despite its small area. In addition, there is a need for more attention to this area and for continues various studies.
