A newly discovered species of the genus Agrostis from Western Himalaya is here described and illustrated. The new species, Agrostis barikii, is considered as a member of Agrostis pilosula group and morphologically closely allied to Agrostis griffithiana by its palea 2/3 the length of the lemma and well-developed awn. However, they differ from the latter by means of the shape of the ligule, length of the lower glume, apex of the lemma, and size of anthers. Data on distribution, habitat and phenology is given along with a photo plate and an illustration.
