Stipules ovate, ca. 1 mm, ciliate; petiole 0.8-1.8 cm, retrorsely hirsute; leaf blade broadly ovate, triangular-ovate, or subflabellate, 1.5-2 × 1.3-1.8 cm, proximal leaves small, sub-flabellate, 3-5-veined, secondary and final veins dichotomously branched, adaxial surface greenish, sparsely covered with short, stinging and puberulent hairs, abaxial surface light green, sometimes lustrous, densely puberulent on veins, base truncate or shallowly cordate, uppermost subtruncate or broadly cuneate, margin unequally 4-5(-7)-crenate or incised-dentate, teeth triangular-ovate, with obtuse or acute tip, 2-5 mm, apex obtuse or acute; cystoliths botuliform, conspicuous on both surfaces. Male cymes in distal axils, many times dichotomously branched, 5-12 mm, never longer than leaves, shortly pedunculate, retrorsely hirsute on axes, sometimes clusters of several flowers below female ones. Female inflorescences in clusters, borne in distal axils or in proximal leafless nodes, or sometimes distal part of main twigs, 3-7 mm in diam. Male flowers light greenish, pedicellate, in bud 2-3 mm; perianth lobes (4 or)5, ovate, ca. 1.5 mm, setulose below apex; stamens (4 or)5; rudimentary ovary broadly obovoid, ca. 0.5 mm.
