The present paper deals with the vegetation of Deedwana tehsil which falls under central part of Rajasthan. A total of 331 species of angiospermic plants belonging to 218 genera and 65 families were recorded including four series of natural vegetation in Deedwana tehsil: 1. Acacia nilotica-Maytenus emarginata-Balanites aegyptiaca series 2. Prosopis cineraria-Crotalaria burhia-Leptadaenia pyrotechnica series. 3. Prosopis cineraria- Capparis decidua-Tephrosia purpuria series and 4. Suaeda fruticosa-Cressa cretica–Heliotropium curassavicum series: The last one is the characteristic of the salty wetland which is situated in the southern part of Deedwana tehsil. Deedwana salt lake which is a unique halophytic floristic tract. Such tracts are unfavourable to the native as well as introduced species, the principal exceptions to this being some salt tolerant members of the Chenopodiaceae. The study provides an understanding of vegetation distribution pattern in arid and semi-arid region alongwith area occupied by salt lake. In the present paper 15 plant species have been recorded as salt loving species of angiospermic plants. Many of these plant species have immediate attention for their conservation.
