Abstract

A revision of the genus Eria Lindl. (Orchidaceae) in the Himalaya has been undertaken to understand the distribution pattern based on the morpho-geographical characters.The herbarium specimens deposited at London and Kathmandu and living collection made from different localities of Nepal were thoroughly examined. It shows that Himalayan Eria is mostly concentrated in the north eastern Himalaya. Among 45 species recorded, 38 species were recorded from north eastern Himalayan region and 18 species from Nepal Himalaya. Among them seven species were local endemic, and three species were Himalaya endemic. Moreover most of the species were distributed between the altitudes of 500-2000 m altitude in the Himalaya.
