A shrub 10 to 16 ft high, with glabrous young shoots; thorns 112 to 2 in. long. Leaves broadly ovate, the base broadly wedge-shaped or rounded, the upper part sharply toothed, and cut up at each side into two or four triangular lobes 14 to 12 in. deep; 112 to 3 in. long, 1 to 212 in. wide; quite glabrous on both surfaces except at first; stalk slender, glandular, up to 118 in. long. Flowers white, 34 to 1 in. across, stalks and outside of calyx glabrous; stamens twenty, anthers pink; styles five. Fruit globose, 58 in. diameter, dark shining crimson.

Discovered in May 1900 by J. Dunbar, on the banks of the Genesee River at Rochester, New York. Its flowers are amongst the largest in the genus, and the handsome fruits remain on the branches till midwinter. Sargent describes it as one of the most ornamental thorns of the northern United States. Introduced in 1901.
