28160D24FFCA05105359FBD32332FEA1.taxon	description	Flowering & fruiting: Flowering from June to October, fruiting not seen. Habitat: The plants grow in tropical semi-evergreen forest patches at an elevation of 1300 – 1600 m. Distribution: China, and now in India. Specimens examined: INDIA, Arunachal Pradesh, Pakke Kessang district, Pakke WLS, N 27 ° 09 ’ 28 ’’, E 93 ° 12 ’ 55 ’’, 1350 m, 08.08.2021. K. Chowlu 41103 (ARUN 000028868); Ibid., N 27 ° 09 ’ 47 ’’, E 93 ° 14 ’ 29 ’’, 1350 m, 30.07.2022. K. Chowlu 41528 (ARUN!); Upper Subansiri district, Muri, near Daporijo, Kumar Ambrish 17238 (ARUN!). Conservation Status: Strobilanthes sunhangii is so far known from two locations in India other than its type locality. The Extent of Occurrence (EOO) of the species is estimated to be less than 5,000 km 2 (c. 3585.820 km 2) with an Area of Occupancy (AOO) of 12 km 2 (AOO based on IUCN standard cell width of 2 km 2). Due to various anthropogenic activities and natural calamities, habitat degradation was observed in the localities. Based on available data, the species is assigned to the category Endangered (EN B 1 ab (iii) & B 2 ab (iii )) according to the IUCN Criteria (IUCN 2012, 2022). Note s: The present collection exhibits some minor variations in calyx and stamen characters compared to those for S. sunhangii reported by Chen et al. (2020). In the present material, the calyx is 8 – 12 mm long and linear-lanceolate (vs. 7 – 8 mm long and ovate), the filaments of the shorter pair are c. 3 mm long and those of the longer pair c. 6 mm long (vs. shorter pair c. 2 mm, longer pair c. 4 mm). The calyx characters of this taxon are matching well with those of S. divaricata (Nees) T. Anderson but Chen’s specimens are showing variations. While consulting ARUN, the second author (AS) found the collection Kumar Ambrish 17238 (Ambrish, 2013) identified as S. divaricata. On close examination, however, the authors identified it as S. sunhangii and both the specimens collected by KC and KA showing the same variations could be due to ecological or phytogeographical factors.	en	K., Chowlu, A., Shenoy, Abstract, K.
