The species is sporadically found in the subalpine–timberline zone of Uttarakhand state. Fascicled white cottony hairs on the abaxial surface in between lateral veins of leaves, bright pink and shine-less corolla and comparatively large calyx with hairy margins distinguish the new species from its nearest ally R. fulgens . The populations of the species were found in two geographically distinct localities in the Rudraprayag and Pithoragarh districts of Uttarakhand state. The distinguishing morphological characters, affinities with other species and various ecological aspects of the new species are discussed here.

Recent field studies have found two additional localities for this species in the state. All three populations were found in the riparian zone especially on rocky substrate rich in limestone. We observed that the Type locality of this species has been severely eroded due to a major flash flood in Kali river during 2013. In this article, we present a description, habitat characteristics, known distribution, and conservation status of L. riparia in the Western Himalaya. The genus Leptodermis Wall. (Rubiaceae) is distributed in the northern hemisphere mainly confined to Himalaya, Japan and China. The generic name is derived from the Greek 'leptos' meaning thin and 'derma' meaning skin or membrane, referring to the thin membranous bractlets that form connate tubes. The genus is characterized by opposite leaves, ofte...

Quercus floribunda from 3000-3600 m. Major associated A total of twelve species of orchids were collected and of species in the habitat include Strobilanthes these one species was of particular interest. On critical atropurpureus, Fragaria nubicola, Cercaea alpina, Carex examination and reference to relevant literature setosa, Impatiens sulcata, Polygonum amplexicaulis, (Chowdhery and Wadhwa, 1984; Deva and Naithani, Anemone rivularis, Pimpinella hookeri and Veronica 1986) the specimen was identified as Neottia pinetorum cana. (Lindl.) Szlach. and on the basis of published literature it was not found previously from the state, which represents the western most range of its global distribution. This locality record of the species is nearly 300 km straight line distance from the previously known locality in Amrit Ganga Valley (Chamoli district) of the adjoining State of Uttarakhand. The species found in a gregarious patch having more than 50 individuals in 0.5 hectare area, its occurrence in Himachal Pradesh is restricted to a single place near Dhela Thatch at geographical co-ordinates of latitude 31°45&amp;#39;45.20&amp;quot; N and longitude 77°27&amp;#39;57.24&amp;quot; E (3400m). This range extension of N. pinetorum is likely being as a result of ban on grazing and recovery of the suitable habitats in recent times, lead to the colonization of this species in newer area.. Terrestrial, up to 28cm high. Stem smooth with or without sheaths. Leaves sessile, broadly cordate or reniform, acute. Inflorescence raceme. Flowers pale-green with brownish-red lip. Bracts shorter than the ovary, ovate-lanceolate, acuminate, convolute. Sepals subequal, spreading, ovate-oblong, subacute. Petals linear, oblong, shorter than the sepals. Lip 3-times longer than the sepals, broadly ovate-oblong, broadest near the apex, narrowed at the base, apex divided into two blunt Distribution: India (Uttarakhand-Kumaun and Garhwal; slightly oblique lobules by a narrow blunt sinus with Himachal Pradesh-GHNP; Sikkim; Arunachal Pradesh); almost parallel sides, the upper surface with two small, China, Nepal and Japan. erect, triangular calli near the base.
