Vitis bryoniifolia
Species of grapevine
Vitis bryoniifolia is a prolific and adaptable, polygamo-dioecious species of climbing vine in the grape family native to China, where it is known as ying yu(Traditional Chinese: 蘡薁 Simplified Chinese: 蘡薁),[1] or hua bei pu tao (Traditional Chinese: 華北葡萄 Simplified Chinese:华北葡萄) (North China grape). The variant form ternata is known as san chu ying yu (Traditional and Simplified Chinese: 三出蘡薁), meaning Three-Spiked-Leafed Ying Yu.
V. bryoniifolia is found in a wide variety of tree-established habitats including forests and shrublands, or fields and valleys where trees are present, especially along the banks of streams; and can be found both in highlands and low- (100–2500 meters above sea-level). It has a long growing season, flowering from April to August, and bearing its fruit (rosy, plum-colored berries, 5–8 mm. in diameter) from June to October; and also a broad distributional range, being reported from 15 of China's 27 provinces and autonomous regions (Anhui, Fujian, Guangdong, Guangxi, Hebei, Hubei, Hunan, Jiangsu, Jiangxi, Shaanxi, Shandong, Shanxi, Sichuan, Yunnan and Zhejiang).[1] It has long been used in Traditional Chinese Medicine as a laxative.
