4172324C4C45FFC3FCA578452E4C1289.taxon	description	Flowering & fruiting from July to September. Habitat: The species grows on an alpine meadow at an altitude of 3678 m. Only four mature individuals were spotted during the entire field survey. The associated species include Cremanthodium reniforme (DC.) Benth., Ligularia kingiana (W. W. Sm.) R. Mathur, L. fischeri (Ledeb.) Turcz. (all Asteraceae), Morina nepalensis D. Don (Caprifoliaceae), Cyanotis vaga (Lour.) Schult. & Schult. f. (Commelinaceae), Rhodiola yunnanensis (Franch.) Fu (Crassulaceae), Geranium sp. (Geraniaceae), Epilobium sp. (Onagraceae), Hemipilia chusua (D. Don) Y. Tang & H. Peng (Orchidaceae), Pedicularis pantlingii Prain (Orobanchaceae), Bistorta macrophylla (D. Don) Soják (Polygonaceae), and Rosa sericea Lindl. (Rosaceae) (Fig. 1 a). Distribution: India, China, Myanmar (Stebbins, 1940; Zhu & Kilian, 2011) (Fig. 2). Specimen examined: INDIA, Nagaland, Kiphire district, Mt. Saramati peak, c. 3678 m, 04.08.2021, S. Dey s. n. (HBARC [HBARC 00006632]). Conservation status: Dubyaea atropurpurea is a rare species, so far known from a few (≤ 10) locations. The Extent of Occurrence is estimated to be less than 20,000 km 2. Also, there is continuing decline of Area of Occupancy due to habitat degradation resulting from various anthropogenic activities. Hence, following IUCN (2012, 2022) this species is categorised as Vulnerable (VU B 1 ab (ii )). Notes: Dubyaea atropurpurea shows close affinity with D. forrestii Mamgain & R. R. Rao in general appearance. However, the former is distinguished from the latter in having hirsute stems, lyrate-pinnatifid leaves, densely hirsute peduncles, larger involucres, involucral bracts in several series, and non-compressed achenes. Whereas, in D. forrestii the stems and peduncles are glabrous, cauline leaves broadly pinnatisect and sub-glabrous, involucres smaller, involucral bracts in 2 – 3 series and the achenes compressed (Mamgain & Rao, 2008). The Indian taxa of the genus Dubyaea can be identified by using the following key.	en	S., Dey, H. A., Barbhuiya (2023): Dubyaea atropurpurea (Asteraceae): an addition to the flora of India.
