Regular and periodical visits to different site and their seasonal appearances were also recorded ( Kotia and Kumar , 2001). Two hundred twelve species were recorded, belonging to one hundred ten genera of flowering plants. About 50 species carry medicinal importance in Ayurveda (Jain, 1968; Jain, 1991, Kotia and Kumar, 2001), some of them are used as fodders and others provide edible fruits. The rich biodiversity of Rajasthan has great potential plants having medicinal value Tannins, oils, Gums & resins, Dyes, Fibers, and other important economic uses. However their characterization is lacking. Present paper has attempted to compile available information on the availability of plant recourses having various potential. The detailed investigation on the molecular & genetic characterization of these plants is necessary to have gene pool conservation. Attempts are also underway to made a gene pool bank for the plants for further reseamles. REFERENCES: 1. Bhandari, M.M. 1978 : Flora Of Indian Desert, Scientific Publishers, Jodhpur, 1- 466. 2.
