A reevaluation of the phytogeographical status of Rajasthan [India] was made. The Perso-Arabian element predominates the Indo-Malayan element almost throughout the state. Drude's (1890, 1913) line of demarcation between Western and Eastern elements was brought more towards the east beyond the limits of Rajasthan. The possible route and means of migration were mentioned with a map. The floristic elements were related to their ecological conditions for determining the possible route of migration of species. Evidence is given in favor of a decreasing barrier effect of Aravallis, regular migration of Western element and increasing desert conditions towards the east. A list of 28 taxa endemic to Rajasthan was included with a map showing their distribution and exact location.
