Darjeeling Himalaya is the Northern most district of West Bengal that covers the hills and mountains that includes the alpine zone in Sandakphu and Phalut to the foothills in Terai at Siliguri with vast stretches of the plains. This region is a home for number of orchid species including number of Bulbophyllum species. In the present investigation, 36 species of Bulbophyllum were found to occur in Darjeeling Himalaya. Of these all were epiphytic except B. odoratissimum Lindl. which was epiphytic and lithophytic. These species flower from April to August to December to January. They were found at 200m at Sevoke forest near Siliguri (B. crassipes Hook. f.) to as high as 2800m at Rachela forest (B. yoksunense J.J. Smith) and at 2700m at Lava range of forest (B. reptans Lindl.). There is no report by earlier workers on ecological status of Bulbophyllum from Darjeeling Himalaya. In the present investigation current ecological status of these species from Darjeeling Himalaya was taken and the following conclusions were drawn. Out of 36 species found in Darjeeling Himalaya, 8 species were common, 8 were sparse, 3 were frequent, 9 rare, 6 threatened and 2 endangered.
