The "Moss Flora of Rajasthan" furnishes the first comprehensive view of the mosses growing in various localities of the state. Floristic studies generally take into account the higher plants growing in an area which form dominant vegetation on the earth's surface. Cryptogamic flora has sttracted comparatively less attention of the taxonomists. The bryophyta flora of Inidan Sub-continent is very poorly studied except some important studies on the Himalayan region. The pioneer work on the mosses of Rajasthan is perhaps the first systematic study in the field of Bryophytes in Rajasthan which provides a key for the isentifications with taxonomic description, distribution and illustrations. This study provides a base for the further researches in the various fields of botanical sciences . The book also gives valuable information of bryoecology and afflinitics of moss flora of the state.
