A deciduous tree or shrub up to 20 or 25 ft high; young shoots furnished with pale hairs; spines very stout, 1⁄2 to 1 in. long. Leaves ovate in main outline, but shallowly lobed and finely toothed, broadly wedge-shaped or rounded at the base, pointed or blunt at the apex; 2 to 4 in. long, 11⁄2 to 21⁄2 in. wide; shining dark green above, loosely hairy in the vein-axils and on the veins beneath; stalk 1⁄2 to 11⁄4 in. long. On vigorous barren shoots the leaves are much more deeply lobed, approaching those of C. oxyacantha in this respect. Flowers white, produced in mid-June, crowded on corymbs 21⁄2 in. wide, each flower about 1⁄2 in. wide; flower-stalks shaggy. Fruit red, shining, 2⁄5 in. long, 1⁄4 in. wide.
