038B87A3FFA4C3352BD158A8FB06FC82.taxon	distribution	Distribution: — Known only from the type locality, the Nonggang National Nature Reserve, Longzhou County, Guangxi Province. Pilea nonggangensis was observed growing on wet limestone in forest shade on a limestone mount at an elevation of 331 m.	en	Fu, Long-Fei, Huang, Shi-Lian, Monro, Alex K., Liu, Ying, Wen, Fang, Wei, Yi-Gang (2017): Pilea nonggangensis (Urticaceae), a new species from Guangxi, China.

038B87A3FFA4C3352BD158A8FB06FC82.taxon	etymology	Etymology: — Pilea nonggangensis is named after the type locality, Nonggang National Nature Reserve.	en	Fu, Long-Fei, Huang, Shi-Lian, Monro, Alex K., Liu, Ying, Wen, Fang, Wei, Yi-Gang (2017): Pilea nonggangensis (Urticaceae), a new species from Guangxi, China.

038B87A3FFA4C3352BD158A8FB06FC82.taxon	discussion	Discussion: — Our analyses of DNA sequence data suggest that Pilea nonggangensis falls within Pilea sect. Tetrameris (BP = 84), a clade demonstrated to be monophyletic by Monro (2006) and characterised by both staminate and pistillate flowers having four tepals. Within sect. Tetrameris Pilea nonggangensis most closely resembles P. basicordata from which it can be distinguished based on sexual system, leaf blade, stipule, inflorescence and bract morphology as summarized in Table 2.	en	Fu, Long-Fei, Huang, Shi-Lian, Monro, Alex K., Liu, Ying, Wen, Fang, Wei, Yi-Gang (2017): Pilea nonggangensis (Urticaceae), a new species from Guangxi, China.

038B87A3FFA4C3352BD158A8FB06FC82.taxon	conservation	Conservation status: — A Global Species Conservation Assessment was undertaken using the IUCN methodology (2001, 2016) using criteria D. Pilea nonggangensis is known from a single locality (IUCN criteria D 2) where the population comprises ca 200 individuals (IUCN criteria D 1). Using the IUCN methodology for P. nonggangensis would be Endangered (EN), however no plausible threat could be found to confirm its status as the population is located within a protected area not under threat in the near future, in addition, considering surrounding area has not been completely explored there may be hitherto undocumented additional populations. For these reasons we have revised the Global Species Conservation Assessment for P. nonggangensis to Vulnerable (VU).	en	Fu, Long-Fei, Huang, Shi-Lian, Monro, Alex K., Liu, Ying, Wen, Fang, Wei, Yi-Gang (2017): Pilea nonggangensis (Urticaceae), a new species from Guangxi, China.
