Shrubs or trees, 40–70 dm. Stems: twigs ± flexuous, new growth pubescent, 1-year old dark-brown (partly covered with abraded cutin), older pale to mid gray; thorns on twigs absent or numerous, straight, 1-year old purple-brown, older gray, slender, 1.5–2.5 cm. Leaves: petiole slender, length 30–45% blade, pubescent, sessile-glandular; blade broadly elliptic or oblong to obovate, 2–3.5 cm, thin, base ± abruptly narrowed, lobes 0, sometimes with only a series of 1–3 subterminal apiculi per side, sinuses lacking or extremely shallow, margins crenate-serrate, teeth gland-tipped, veins 3–5 per side (except smaller leaves), apex subacute to acute, often ± cuspidate, abaxial surface glabrate young, adaxial sparsely hairy young, especially on midvein, glabrescent. Inflorescences 1–5-flowered; branches finely pubescent to pilose; bracteoles caducous, narrowly oblong, margins glandular. Flowers 15–20 (–25) mm diam.; hypanthium sparsely pilose; sepals triangular, margins irregularly, strongly glandular-serrate, abaxially glabrous; stamens 20, anthers pale-purple; styles 3–5. Pomes orange flushed red to red, suborbicular, 10–15 mm diam., glabrous; sepals recurved; pyrenes 3–5.
