'Ampelopsis brevipedunculata' from the website Trees and Shrubs Online (treesandshrubsonline.
A vigorous climber with roughly hairy young shoots. Leaves distinctly three; rarely five-lobed, the side lobes spreading and pointed; heart-shaped at the base; 2 to 6 in. long and wide, coarsely toothed, the teeth rounded, but ending in a minute abrupt point (mucro); dark green above with scattered short hairs at first; bristly hairy beneath; stalk from three-fourths to as long as the blade, very hairy, especially at first. Inflorescence hairy, once or twice forked, each fork terminated by a cymose flower-cluster. Fruit 1⁄4 to 1⁄3 in. across, amethyst blue.
cv. ‘Citrulloides’ – Although described from a cultivated plant, this variant occurs in the wild in Japan, Korea and China (f. citrulloides (Lebas) Rehd.).
var. maximowiczii – This variety was reintroduced to Kew in 1982 from the island of Ullung-do off the east coast of South Korea (B.E. & C. 94).
Leaves handsomely splashed with pink and white, and the young shoots pink. It is too delicate to thrive away from a wall. Introduced by Siebold before 1847.
