Shrubs, monoecious (often apparently dioecious), 5–10 dm. Stems sparsely branched, branches ascending, longest leafy branchlets to 30 (–55) cm. Leaves: petiole 0–1 mm; blade elliptic or obovate to orbiculate, 7–25 × 6–20 mm, base cuneate to cordate, apex acute to rounded or mucronate, abaxial surface glabrous or pilose, adaxial surface glabrous or midvein pilose; secondary-vein pairs 4–7, clearly visible.
