Shrubs or trees, 100 dm. Stems: older trunk bark nearly black, grooved, younger gray, fibrous, checked into longitudinal plates; twigs: new growth lanate, 1-year old pale grayish tan, older gray; thorns on twigs absent or frequent, straight, 2-years old ± bright chestnut brown or shiny black, fine, 4–5 cm. Leaves: petiole length 37–43% blade, tomentose young, glabrescent, eglandular; blade broadly elliptic, narrowly rhombic, rhombic, rhombic-ovate, or broadly ovate, 4–7 cm, thin, base broadly cuneate to rounded, lobes 1–4 per side, sinuses shallow to deep, lobe apex obtuse to subacute, margins strongly serrate except proximally, teeth 2–3 mm, veins 5 per side, apex acute to subacute or obtuse, abaxial surface sparsely to densely white-tomentose young, less dense mature, veins densely hairy, adaxial densely scabrous young, glabrescent. Inflorescences 7–12-flowered; branches tomentose, sometimes glabrescent; bracteoles caducous, ± linear, (larger) herbaceous to (smaller) membranous, margins glandular. Flowers 14–22 mm diam.; hypanthium tomentose; sepals narrowly triangular, 4–6 mm, margins glandular-serrate to glandular-laciniate, abaxially densely pubescent; stamens 20, anthers rose, rose-purple, red, or purple; styles 4 or 5. Pomes red, sometimes red-orange, suborbicular, 9–14(–25) mm diam., with remnant tomentum; sepals often eroded or broken, spreading; pyrenes 4 or 5.
