Psammogeton hirsuta (Apiaceae; Pimpinelleae), a new species from India

Psammogeton hirsuta sp. nov. (Apiaceae), a novel species collected from specifically the lowlands of Jammu and Kashmir, north-west India’s subtropical region, is described and illustrated. Psammogeton hirsuta resembles one of its close relatives, P. canescens , and P. shivalikense ; however, it differs significantly in terms of the plant being hirsute, sheaths of leaf bases, ciliate peduncle degree of pubescence, bracts and bracteoles, and fruit shape. Additionally, we provide phenology, a distribution map, a comparison of species with comparable morphologies, and a key to closely related species.
