is a deciduous liana that twines around other bodies with its
tendrils. Leaves are alternate; blades are 5-8cm in length and
width, ovate to broad ovate-like triangular. The leaves generally
cleft in 3-5. Still, the cutting is variable, with shallow
serrations on margins and bases with deep heart-shaped. Surfaces
arachnoid first but becomes glabrous later, back surfaces with light
brown or white arachnoid hairs that remain until autumn and
2.5-8cm-long petioles. Dioecious: Six-twelve centimeter-long
panicles emerge opposite to leaves and set small green flowers. The
inflorescences of bisexual flowers are smaller, and the flowers are
sparse. Sap fruit, about 6mm across, spherical, matures in black.
Bloom time: June-August.
