Shrubs, 60 dm. Stems: twigs: new growth green, glabrous, 1-year old shiny, mid brown, older deep gray; thorns on twigs frequent, recurved, 1-year old shiny reddish to blackish brown, slender to moderately thick, 2–4.5 cm. Leaves: petiole length 40% blade, glabrous, densely glandular; blade broadly ovate to oblong-ovate or broadly elliptic, smaller sometimes ± rhombic, 3–5 cm, on extension shoots larger, often suborbiculate, thin to chartaceous, base cuneate to broadly cuneate or ± rounded, lobes 4 or 5 per side, sinuses shallow, lobe apex triangular, margins serrate teeth numerous, small, veins 6–8 per side, apex acute, abaxial surface glabrous, adaxial densely appressed-scabrous young, glabrescent. Inflorescences 6–10-flowered; branches pilose; bracteoles linear, membranous, margins sessile-glandular. Flowers 16 mm diam.; hypanthium pubescent; sepals narrowly triangular, 6 mm, margins glandular, sometimes barely glandular-serrate, abaxially glabrous; stamens 20, anthers cream; styles 3 or 4. Pomes reddish, broadly ellipsoid to suborbicular, 11–14 mm diam., smooth, glabrous; sepals spreading, often erose; pyrenes 3 or 4.
