During the course of floristic exploration in Chamoli District (Uttarakhand State, India), the authors came across populations of Sarcopyramis Wall., growing in a shady moist locality of Panichhoya forest of Gairsain (Chamoli), on the right flank of river Ramganga. Critical examination revealed the plant as Sarcopyramis napalensis Wall. of Melastomataceae. Two populations ca. 150–200 individuals each were observed under the present study. So far, this species has been recorded in Arunachal Pradesh, Assam, Mizoram and Sikkim in eastern Himalaya and recently, its occurrence was reported in western Himalaya by Pusalkar (2013). The species has not been reported by earlier workers from Garhwal Himalaya (Duthie 1903; Babu 1977; Raizada & Saxena 1978; Polunin & Stainton 1984; Naithani 1984–85; Gaur 1999; Uniyal et al. 2007). Thus, this is the first report on the occurrence of Sarcopyramis napalensis Wall. in Garhwal Himalaya and an addition to the ‘Flora of Chamoli’ as well. The voucher specimen has been deposited at HNB Garhwal University Herbarium, Srinagar Garhwal, Uttarakhand (GUH 20736).
