Abstract
A plant formerly misidentified as Amomum maximum in Guangxi, China, is described here as a new species, namely A. fangdingii. A detailed description, distribution map and illustrations are provided together with a taxonomic key distinguishing A. fangdingii from eight morphologically similar species characterised by cincinnate inflorescences occurring in Cambodia, China, Laos and Vietnam.
Keywords: Amomum maximum, A. velutinum, gingers, misidentification, Monocots.
