Gray places the genus Malus as a section in the larger genus Pyrus, but most modern botanists treat Malus separately. Gray’s description:

PYRUS [Tourn.] L. Calyx-like receptacle urn-shaped, bearing б sepals. Petals roundish or obovate. Stamens numerous. Styles 2-5. Fruit a large fleshy pome, or smaller and berry-like, the 2-6 cells imbedded in the flesh, papery or cartilaginous, mostly 2-seeded. —Trees or shrubs, with showy flowers in corymbed or umbellike cymes. (The classical name of the Pear-tree.) A large genus, often subdivided, but with sections less strongly or constantly marked than our few species would suggest.

MALUS (Hill) S. F. Gray. (APPLE.) Leaves simple; orifice of concave receptacle open; flesh of large subglobular fruit copious, free from sclerotic cells. Malus [Tourn.] Hill.

Leaves and usually the outer surface of the calyx-lobes glabrate.

Calyx-lobes persistent in fruit.

P. coronaria L. (AMERICAN CRAB.) Tree, somewhat armed, 6-10 m. high; leaves ovate or elliptic, usually rounded or even cordate at the base; those of the sterile shoots somewhat triangular-ovate and lobed, sharply serrate; petals broadly obovate, white or nearly so; pome greenish-yellow, hard and sour, 2-2.6 cm. in diameter, depressed-globose. (Malus Mill.) — Thickets and open woods, N. J. to Ont., Kan., and southw.
