Profound field inventory and monitoring of threatened species habitats are cost-prohibitive, if there is little known about the distribution of species. Malaxis muscifera is a habitat specific, threatened medicinal orchid constitute of Astavarga which grows between 2500-3700 m in the alpine region of Himalaya. Its population decline is closely link...

Gastrochilus affinis (King & Pantl.) Schltr. is reported here for the first time from Western Himalaya. Gastrochilus nepalensis Raskoti, a species from Nepal described in 2015 is reduced to synonymy under G. affinis. A note on typification of G. affinis is also provided in the present communication.

Increase in endemism with elevation is a common feature in Himalayas because of increased isolation of higher areas like treelines. To protect species of treeline, we at least need to record their numbers and distribution. We estimated that the total number of tree species in Himalayan treeline is 58, and they belong to 14 genera and 8 families. It...
