This thesis consists of four chapters, which together contains the results of the author's floristic studies on the flowering plants of Makkah and his chemotoxonic studies of Cassia senna and Cassia holosericea. The first chapter includes a phyto-geographic account of and a floristic history of Saudi Arabia and ends with a listing of the research objectives of the present study. Chapter two delineates the area of study and contains full details of both the botanical and chemical experimental methods employed in the floristic and soil analysis studies. In the main chapter three, the first flora of Makkah is presented, together with the first English-Arabic glossary of botanical terms. This chapter also includes a detailed Discussion and Commentary on the flora of Makkah together with the results of the first soil analysis of this region of Saudi Arabia. The final chapter four contains the experimental methods used in a chemotaxonomic study of two morphologically identical Cassia plants, namely of C. senna and C. holosericea. For the chemical studies, the technique of paper chromatography and electrophoresis were employed, whilst for the taxonamic studies, light and scanning electron microscopic investigations were performed. These studies showed that at the chemical level and at the microscopic level the two plants could be distinguished and it is thus concluded that either they should retain their separate species classification or that they should be considered as subspecies.
