Shrubs, 20 dm. Stems spreading, brown becoming grayish black, glabrous or finely stellate-hairy. Leaves: stipules oblong to elliptic or obovate, 6 × 2.5 mm, base broad, apex rounded and erose to apiculate or acute; petiole 1–2.5(–3) cm; blade broadly ovate to orbiculate, 2–6 × 2.5–6 cm, sometimes wider than long, base truncate to slightly cordate, 3- or 5-lobed, clefts between lobes may be shallow to deep, margins doubly crenate to doubly serrate, apex rounded, obtuse, or acute, surfaces glabrous or sparsely stellate-hairy (more so on abaxial veins). Inflorescences 15–20-flowered, fairly dense, hemispheric racemes, 2.5–4 cm diam.; bracts narrowly obovate to spatulate, 4.5 mm, apex erose or acute. Pedicels 8–15 mm, densely stellate-hairy.

Follicles 2(3), ovoid, flattened, 2.5 mm (lengths not exceeding sepals), keeled apically, densely stellate-hairy, hairs white; styles 2.5–3 mm. Seeds 1 or 2, pyriform, 1.5 mm.
