Key words: Angiosperm, Flora, Nagaland, New additions, North-East India INTRODUCTION To strengthen the National Herbarium of Medicinal Plants (FRLH) in Foundation for Revitalisation of Local Health Traditions (FRLHT), Bengaluru, India, the botanical team had undertaken floristic surveys in the forests of Dimapur, Peren and Kohima districts of Nagaland state during September 2015. During this extensive field exploration, the authors have col- lected several plant specimens (200 voucher specimens), of which, based on critical study, 13 plant taxa are interesting and show new distributional report to Nagaland state. These specimens were confirmed by referring various literature (Hooker 1872 – 1897; Kanjilal et al. 1934 – 1940; Balakrishnan 1981, 1983; Chowdhery & Wadhwa 1984; Haridasan & Rao, 1985, 1987; Sanjappa 1992; Chaudhuri 1993; Sharma & Sanjappa 1993; Hajra et al. 1995a,b; Chauhan 1996; Chowdhery et al. 1996, 2008; Polunin & Stainton 1997; Singh et al. 2000a,b; Singh 2001; Kumar & Singh 2001; Singh et al. 2002; Balakrishnan et al. 2012) and also the specimens were compared with authentic herbarium specimens deposited at Botanical Sur- vey of India, Shillong, Kolkata and Kew Digital Herbarium. All the 13 plant taxa namely Anaphalis royleana, Boehmeria penduliflora, Byttneria pilosa, Cirsium verutum, Glochidion multiloculare var . pubescens, Inula cuspidata, Myriactis wallichii, Phyllanthus rheedei, Sarcochlamys pulcherrima, Swertia ciliata, Symplocos sumuntia, Tetrastigma serrulatum and Uraria crinita are presented here in alphabetical order with updated nomenclature, family, phenology, habitat, distribution and specimens examined. All the voucher specimens are deposited at FRLH Herbarium, Bengaluru. Pleione 12(1): 118 - 127. 2018.
