Abstract
The goal of the study is to provide a comprehensive taxonomic account of 12 endemic species of Astragalus occurring in India. The north-west Himalayan region harbors more endemic species (11 spp.) than eastern Himalaya where only two species have been noticed from Sikkim. Jammu & Kashmir with seven species occupies first position in the list of endemic species. Five species are strictly confined to Jammu & Kashmir, while two species to Uttaranchal and one species to Sikkim. Only one species (A. tenuicaulis) is found in both the Himalayas, otherwise the elements of both the Himalayas are quite distinct from each other. Most of the endemic species of Astragalus have been observed quite rare in the nature except A. uttaranchalensis. In the present investigation, A. turgidus, a newly described species from Jammu & Kashmir, has been found conspecific to A. kashmirensis. For each species nomenclature, description, distribution, phenology, taxonomic notes, list of the investigated materials, distribution map and figures are given. A new combination A. falconeri var. pilosus (Ali) Chaudhary has been proposed based on A. hoffmeisteri var. pilosus Ali. A new endemic species A. nainitalensis from Kumaon Himalaya has also been described here along with illustrations.
