Psammogeton hirsutus Bhellum and Magotra (Apiaceae), a novel species collected from the lowlands of Jammu and Kashmir, north-west India's subtropical region, is described and illustrated. Psammogeton hirsutus resembles one its close relatives P. canescens and P. shivalikense; however, it differs significantly in terms of the plant being hirsute, sheaths of leafbases, ciliate peduncle degree of pubescence, bracts and bracteoles, and fruit shape. We provide data on phenology, distribution map, a comparison of species with comparable morphologies, and a key to closely related species.
