Taxonomic details ofGeocalyx graveolens Nees recently discovered from the Valley of Flowers in western Himalayas (altitude ca 4670 meters) have been provided. The discovery of this genus in the above area not only extends its range of distribution in the Himalayas but also coastitutes a new record of this taxon in Indian bryoflora. The plants are monoecious and characterized by undulating stem, bifid leaves which are flat or ascending, and bifid underleaves. The androecial and gyaoecial branches are ventral and axillary. The marsuplum arises initially as tuber-like structure (often 2–8 in number on the ventral surface of a plant) and, at maturity becomes cylindrical with numerous rhizoids studded on its surface.
