Re-collection of the Black Catchfly Silene nigrescens (Caryophyllales: Caryophyllaceae) after 130 years from Indian western Himalaya
Main Article Content
Abstract
Silene nigrescens has been re-collected after a gap of 130 years from Pangarchulla area of District Chamoli, Uttarakhand, India. This species was earlier collected by J.F. Duthie from the above-mentioned location in 1885. On the basis of J.F. Duthie’s collection this species is known from only two localities (Pangarchula area and Nila valley) in western Himalaya. Due to a dispersed type of distribution, extremely rare occurrence and poor herbarium history, this species should be considered as a conservation dependent species in the western Himalaya.Â
