Abstract: Neosinocalamus affinis (Rendle) Keng f. is endemic to China, and it is mainly distributed in Sichuan Basin, Gansu, Shanxi, Hubei, Hu'nan, Chongqing, Guizhou, Yunnan, and Guangdong. Currently, four cultivated forms and four non-named cultivars of N. affinis were recorded. Thus, all the recorded cultivated forms and non-named cultivars of N. affinis need to be unified, standardized and named according to the updated International Code of Nomenclature for Cultivated Plants (ICNCP). Eight cultivars of N.affinis ‘Chrysotrichus’, N. affinis ‘Viridiflavus’, N. affinis ‘Flavidorivens’, N. affinis ‘Striatus’, N. affinis ‘Foducizhu’, N. affinis ‘Niutuizhu’, ‘N. affinis ‘Shetouzhu’ and N. affinis ‘Doupengzhu’ have been described and named in accordance with the ICNCP.
