Shrubs or trees, 100 dm. Stems: trunk bark dark gray or brownish, rough; twigs ± flexuous, new growth pubescent, 1-year old dark-brown; thorns on twigs few to numerous, straight, 1-year old very dark, slender, 1.5–3 cm.

Inflorescences 2–4-flowered; branches glabrate to pilose; bracteoles caducous, linear, margins glandular. Flowers 14–18 mm diam.; hypanthium glabrous or pilose; sepals triangular, margins irregularly glandular-serrate; stamens 20, anthers pale to bright purple; styles (2 or) 3–5. Pomes orange or orange flushed red to red, suborbicular to pyriform, 10–12 mm diam., glabrous; sepals recurved; pyrenes (2 or) 3–5.
