Several new records were found during our plant resources investigation in Centianhe National Wetland Park in Jianghua County of Hunan Province from 2017 to 2018. In this paper, we report a newly recorded family of monocotyledonCostaceae Nakai, including a newly recorded genus Hellenia Retzius and a newly recorded species Hellenia speciosa (J. Koenig) Govaerts in Hunan Province. Meanwhile, we make a brief overview on taxonomic study of Costaceae and a new accept name of Crape Ginger. The finding of Costaceae in Hunan provides basic and important data for studying biodiversity and floristic composition in this area.
