-'''''Dioscorea polystachya''''' is a species of flowering plant in the [[Dioscoreaceae|yam family]] known by the common names '''Chinese yam''' and '''cinnamon vine'''. It is native to eastern [[Asia]] ([[China]], [[Japan]], [[Korea]], [[Kuril Islands]]), and it is naturalized in the central and eastern [[United States]].<ref name=i>[http://apps.kew.org/wcsp/namedetail.do?name_id=240732 Kew World Checklist of Selected Plant Families]</ref><ref name=feis>Gucker, Corey L. 2009.

-''Dioscorea polystachya''  is a vine up to 5 meters long or longer. It twines clockwise. The leaves are up to 11 centimeters long and wide. They are lobed at the base and larger ones may have lobed edges. The arrangement is variable; they may be alternately or oppositely arranged or borne in whorls. In the leaf axils appear warty rounded [[bulbil]]s under 2 centimeters long. New plants sprout from the bulbils or parts of them. The flowers are [[cinnamon]]-scented. The plant produces one or more spindle-shaped<ref name=fna/> or cylindrical<ref name=feis/> tubers. The largest may weigh 10 pounds and grow one meter underground.<ref name=feis/>
-''Dioscorea polystachya'' was introduced to the United States in the 1800s when it was planted as an [[ornamental plant|ornamental]] or food crop. It and other introduced yam species now grow wild there. It is troublesome in [[Great Smoky Mountains National Park]], where its range is "rapidly expanding".<ref name=feis/> It is most prevalent in moist habitat types. It is more tolerant of frost than other yams and can occur in temperate climates as far north as [[New York]].<ref name=feis/><ref>[http://bonap.net/MapGallery/County/Dioscorea%20polystachya.png Biota of North America Program, 2013 county distribution map]</ref>
