Dioscorea cirrhosa, commonly known as the dyeing yam, is a species of flowering plant in the family Dioscoreaceae. It is a perennial, dioecious climbing vine native to Southeast Asia. [1] [2] [3]
Dioscorea cirrhosa is a right-twining vine that grows annually from a tuberous rhizome. [3] Its stems can reach lengths of up to 10 meters. The plant features heart-shaped leaves and is dioecious, meaning male and female flowers are borne on separate plants. [3]
This species is native to regions of Indo-China, including northeastern Thailand, Laos, and Vietnam, as well as southeastern China (Guangxi, Guangdong), Hong Kong, Taiwan, and the southern Ryukyu Islands (Japan). [1] It typically grows in subtropical forest understories, where it climbs over other vegetation to access sunlight. [2]
Dioscorea cirrhosa has historically been used as a source of dye. The plant's tuber was once traded internationally for its dyeing properties, making it an important economic resource in certain regions. [3] [1]
