Morphological Description

Branchlets terete, slender, with longitudinal ridges, sparsely white lanate; tendrils unbranched or mixed with bifurcate ones. Leaves simple; stipules green-brown, ca. 0.8 × 0.7 mm, submembranous, glabrous, apex obtuse; petiole 1-3 cm, with sparse arachnoid tomentum; leaf blade 3-7 × 2-4 cm, abaxially with dense gray-white or gray-brown arachnoid tomentum, adaxially subglabrate, basal veins 3, lateral veins 4 or 5 pairs, veinlets tomentose and raised abaxially, not raised adaxially, base subcordate, subtruncate, or subrounded, notch very short, margin 7-10-toothed on each side, teeth fine and sharp, apex acute or acuminate. Panicle leaf-opposed, terete, basal branches undeveloped; peduncle 0.5-1.2 cm. Pedicels 2-3 mm, slender, glabrous. Buds elliptic or obelliptic, 1.5-1.8 mm, apex rounded. Calyx glabrous, teeth inconspicuous. Petals ovate-elliptic, 1.2-1.6 mm. Filaments filiform, ca. 1.2 mm; anthers yellow, oblong, ca. 0.5 mm. Disk well developed and pistil entirely abortive in male flowers. Berry purple-black and glaucous at maturity, globose, 6-10 mm in diam. Seeds obovoid, apex rounded and retuse, chalazal knot rounded, ventral holes furrowed from base upward nearly to tip.
