This ecoregion represents pine forests distributed in three isolated patches of 9,600 km² at elevations between 1,500 and 2,500 m in the Naga Hills, between India and Myanmar. At lower elevations, Tenasserim pine dominates, usually in association with broadleaf trees such as species of Dipterocarpus. In higher elevations, the Tenasserim pine trees are replaced by Khasi pine and blue pine, usually in association with hemlock and spruce, mixed with broadleaf trees such as maples, oaks, and rhododendrons. The forest undergrowth is sparse but for a few herbaceous plants such as Anemone, Crotalaria, and Desmodium. Many orchids grow on the trunks of mature pine trees, including species of Bulbophyllum, Cleisostoma, Coelogyne, Cymbidium, Dendrobium, and Vanda.
