older growth grayish, rough, glabrescent.

additionally with line of fine, curved, simple hairs extending from node to node and decurrent from leaf base;

older twigs brown or greenish brown to gray.

stipules linear-subulate, 3–10 mm;

petiole primarily in distal 1/2, sometimes themselves shallowly pinnately lobed, surfaces scabridulous, hairs appressed-stellate, obscure nectary present abaxially on midvein near base.

stipules narrowly triangular, 2–4.5 mm;

petiole mostly 1/4–3/4 blade, with line of fine, curved hairs adaxially;

blade broadly ovate to transversely broadly ovate, usually 3-lobed or 3-fid, mostly 1.2–4.5 × 1.2–4.3 cm, base cordate to truncate, rarely broadly cuneate, margins irregularly crenate to serrate, apex obtuse to broadly acute, apex of lateral lobes obtuse or broadly acute, surfaces scabridulous, hairs appressed-stellate, nectary present abaxially at base of midvein.

solitary flowers in axils of distal leaves.
