Ampelopsis glandulosa var. heterophylla f. citrulloides is a perennial liana occurring in fields and mountains whose bases lignify. Young stems have coarse hairs and dichotomous tendrils at the nodes, which become opposite the leaves. Leaves are alternate, 6-12cm long and 5-9cm wide, pentagonal-lobed, and deeply cut into 3-5 lobes with pointed tips. The leaves are thick, with glossy surfaces, coarse hairs on the backsides' veins, and coarse serrations on the margins. Cymes appear opposite the leaves and set many flowers. The flowers are approximately 3mm across, light green, and have five petals. Sap fruit is 6-8mm in diameter, spherical, and matures in green-white, purple, and blue. Bloom time: July-August.
