Online published on 21 August, 2018. Abstract The Darjeeling part of the Himalayas has its own climatic peculiarities due to its geographical location, relief and wide range of altitudinal variations ranging from ±120 to 3660 m amsl. The varied climatic, physiographic, altitudinal range and the edaphic factors have enabled the region to evolve the rich diversity of orchid species including Dendrobium species. The different conditions of slopes, small terraces, hill ridges, river valleys, the diversity of habitat conditions and the diverse type of vegetation conditions have altogether contributed to its unique and diverse floristic diversity. The major climatic variation in Darjeeling is based mainly upon the elevation. The climatic variation is also responsible for the creation of wide range of vegetation structure including orchids and it supports the survival of great biological diversity. Present paper deals with flowering and fruiting, altitudinal range, local distribution, general distribution, field status and medicinal evaluation of six additional Dendrobium spp (Orchidaceae) from Darjeeling Himalaya of West Bengal, India.
