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. Leaves: petiole slender, length 25–40% blade, winged distally, pilose, sessile-glandular; blade rhombic-elliptic to rhombic-obovate or trullate, 1.5–3 cm, thin, base ± broadly cuneate, lobes 0, or 1 or 2 per side, sinuses shallow, lobe apex subacute, margins obscurely crenate teeth sharper young, veins 3 or 4 (or 5) per side, apex acute to subobtuse, abaxial surface sparsely pilose young, adaxial conspicuously pilose on veins, otherwise glabrate. 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.


Phenology: Flowering Apr; fruiting Sep–Oct.
Habitat: Dry woods, gravelly ridges, sandy soil
Elevation: 20–100 m
