Pyurs platycarpa, Bailey (Malus platycarpa, Rehd.). Small tree, to 20 ft., with spreading unarmed branches, young growths thin-tomentose but becoming glabrous: lvs. ovate to elliptic, rounded at base, the apex rounded but with short acute point, sharply and mostly doubly serrate, those on vigorous shoots broad-ovate and usually with several pairs of very broad triangular lobes: fls. 3-6 in raceme-like umbels, about 1/2in- diam., on glabrous pedicels 1-1 1/2 in. long; calyx-tube obconic and glabrous, the lobes or sepals lanceolate-acuminate and longer than the tube and densely tomentose within though glabrous without; petals orbicular-ovate, usually dentate; styles 5, villous below the middle and connate for one-third their- length: fr. depressed- globose with deep depressions at both ends, broader than long (2 in. diam.), with persistent calyx, sometimes used for preserves. N. C. to Ga. in fertile bottoms. S.T.S. 2:189.—Mostly closely related to P. coronaria, but easily distinguished from this as well as from other species by the broad and large lvs. which are rounded and abruptly acuminate at apex, and never lobed, and by its very large fr. Var. Hoopesii, Bailey (Malus coronaria var. Hoppesii, Rehd. M. platycarpa var. Hoppesii, Rehd.). Differs in pubescent calyx, oval to elliptic lvs. only slightly or not at all lobed, and by the larger fr. Known only in cult.
