Morphological Description

Plants polygamo-dioecious. Branchlets terete, slender, with longitudinal ridges, with sparse arachnoid tomentum; tendrils bifurcate, leaf-opposed. Leaves simple; stipules brownish, elliptic-lanceolate, 2.5-3.5 × 1-1.5 mm, membranous, glabrous, entire, apex obtuse or acute; petiole 1.5-4 cm, with arachnoid tomentum when young, then glabrate; leaf blade ovate or oval, 3-lobed or inconspicuously 3-5-divided, 3-7 × 2.5-6 cm, abaxially white with sparse arachnoid tomentum when young, then glabrate, adaxially glabrous, basal veins 5, lateral veins 4 or 5 pairs, veinlets conspicuous at fruiting stage, base cordate, margin 5-13-toothed on each side, teeth obtuse, apex acute or acuminate. Panicle leaf-opposed, 2.5-4 cm, narrow, basal branches undeveloped; peduncle 1.5-2.5 cm, with sparse arachnoid tomentum. Pedicel 2-3 mm, glabrous. Buds obovoid-elliptic, 1.5-2.5 mm, apex rounded. Calyx ca. 2 mm, subentire. Filaments filiform, 1.2-1.8 mm; anthers yellow, elliptic, ca. 0.5 mm. Pistil abortive in male flowers. Berry globose, 6-7 mm in diam. Seeds obovoid, apex retuse, chalazal knot elliptic, ventral holes furrowed from base upward nearly to apex.
