Taxonomic Rank: Magnoliopsida: Rhamnales: Vitaceae
Synonym(s): sorrel vine
Appearance
Cayratia japonica is a perennial vine with compound leaves.
Foliage
Each leaf has 5 leaflets that are ovate to orbicular, 1.2-3 in. (3-8 cm) long and 0.5-1.5 in. (1.5-4 cm) wide. Tendrils grow opposite each leaf.
Flowers
Flowering occurs in the late summer. The small, salmon-colored flowers develop in umbels.
Fruit
Fruits are black or white berries that each contain 2-4 seeds.
Ecological Threat
It is thought that Cayratia japonica only reproduces vegetatively in North America. Vines can readily climb over other vegetation, where it can block out sunlight to the plants below. It is native to temperate and sub-tropical Asia.
