PYRUS

lanceolate-acuminate and densely tomentose within; 

 petals oval, rounded at top, more or less gradually nar- 

 rowed into a claw; styles slightly shorter than the 

 stamens: fr. flattened and concave at both ends, 

 broader than long, not angled, yellow and waxy at 

 maturity, fragrant. N. Y., and southward in the 

 Appalachian region to N. C.; early-flowering. S.T.S. 

 2 : 157. This species is often confused with the follow- 

 ing, but is easily distinguished by its distinctly lobed 

 cratoegus-like Ivs. whitish on their under side. 



42. coronaria, Linn. (Malus fragrans, Rehd. Malus 

 coronaria, Mill.). Closely related to P. glaucescens, 

 but differing in less deeply lobed more elongated Ivs. 

 which are green and not glaucous beneath at matu- 

 rity, glabrous calyx-tube, and the fr. being strongly 

 ribbed at the deeply sunken apex. N. Y. to Ala. 

 B.M. 2009. B.R. 651. S.S. 4:167 (all as P. coronaria). 

 R.H. 1884, p. 104 (as P. microcarpa coronaria). Gn. 

 29, p. 395; 34, p. 206. The fr., which is produced 

 in abundance, was often buried by the early settlers 

 for use in the spring, when its acerbity was largely 

 extracted; and it was sometimes used for cider. It is 

 also useful for jellies and preserves. The species was 

 probably never intro. into cult, for its frs., although it 

 has been long grown for ornament and under domesti- 

 cation the apples are often twice their natural size. Var. 

 elongata, Bailey (M. fragrans var. elongdta, Rehd. M . 

 coronaria var. elongata, Rehd.). Lvs. narrow-triangu- 

 lar and distinctly incised-serrate or lobed. N. Y. to 

 N. C. There is a form with semi-double fls. and one 

 (var. aucubaefolia, Bailey) with variegated Ivs. An 

 attractive species. For recent discussions of the 

 nomenclature of this species and No. 38, see Jackson, 

 G.C. III. 55, p. 294, and Rehder, M.D., 1914, pp. 

 260-61. 



43. glabrata, Bailey (Malus glabrata, Rehd.). A 

 southern representative of P. glaucescens, native from 

 N. C. to Ala., distinguished by the Ivs. light green and 

 not glaucescent on the lower surface and rather thin, 

 glabrous, deeply lobed, distinctly cordate at base, and 

 the lowest pair of lateral veins springing from the very 

 base of the blade: calyx-tube glabrous and purple; 



cc. Foliage tomentose or villous or pubescent at maturity, 

 at least on the vigorous shoots, the Ivs. thickish and 

 strongly veined. 



44. ioensis, Bailey (P. coronaria var. ioensis, 

 Wood. Malus ioensis, Brit. Malus coronaria var. 

 ioensis, Schneid. P. iowensis, Camith?). PRAIRIE or 



3298. A wild crab of the East. Pyrus glaucescens ( X %). No. 42. 



petals suborbicular or broadly ovate or rarely oval, 

 abruptly contracted into a short claw, often erose- 

 denticulate; styles 5, slightly longer than the stamens: 

 fr. depressed-globose and slightly angled, distinctly 

 ribbed at the deeply sunken apex. S.T.S. 2:188. 



WESTERN CRAB-APPLE. Fig. 3300. Small tree, the 

 younger parts gray-woolly: TVS. from ovate-oblong to 

 elliptic-obovate, irregularly and mostly bluntly toothed 

 and the larger ones marked with right-angled notches 

 of shallow lobes, very tomentose below or becoming 

 rusty and rarely glabrate with age, the petioles short and 

 stout and pubescent : fls. usually upon shorter pedicels 

 which, like the calyx, are tomentose : fr. oblong or at least 

 never flattened lengthwise, sometimes angular, larger 

 than in P. glaucescens and clinging later to the tree, dull 

 heavy green with numerous light-colored dots on the 

 skin, the surface having a greasy feel, the st. short and 

 thick as compared with No. 41, and set in an oblique 

 cavity, the basin narrow and shallow, with variable cor- 

 rugations and a closed and pubescent calyx, the flesh 

 sour and austere. Wild in low or flat lands in the Missis- 

 sippi Valley, the typical form, as understood by Rehder, 

 ranging from Minn, and Wis. to Neb., Kans., and Mo. 

 B.M. 8488. S.S. 4:168 (frs. too flat). Frs. appro- 

 priated by the settlers, but the species is probably not 

 in cult, for its fr., although a late-blooming double-fld. 

 variety has been lately intro., Bechtel's crab, some- 

 times referred to P. angustifolia. G.C. III. 25:397. 

 R.B. 38:185. R.H. 1910:60. P. ioensis is a variable 

 species, in some of its forms difficult to separate from P. 

 coronaria, P. angustifolia, and other species. Var. Pal- 

 meri, Bailey (M. ioensis var. Pdlmeri, Rehd.). Small 

 and slender tree, to 18 ft., differing from the type 

 chiefly in the smaller oblong more thinly pubescent 

 Ivs. which are rounded at apex, and those on the flow- 

 ering shoots not lobed and crenate-serrate. Mo. Var. 

 spinosa, Bailey (M. ioensis var. spindsa, Rehd.). 

 Dense bushy shrub, 6-8 ft., with slender spiny branches: 

 differs from var. Palmeri in a shrubby habit, smaller 

 Ivs. and fls., and glabrescent calyx: from P. coronaria 

 (P. angustifolia) in the pubescence of the Ivs., serrate 

 or serrulate If.-margins and lobed ovate Ivs. of the 

 strong shoots. Mo. Var. Bushii, Bailey (M . ioensis var. 

 Bushii, Rehd.). Differs in bearing less deeply lobed Ivs. 

 than the type, which are glabrescent: from var. Pal- 

 meri it differs in having oblong-lanceolate acute gla- 

 brescent Ivs. Mo. Var. creniserrata, Bailey (M. ioen- 

 sis var. creniserrata, Rehd.), is a slender spineless tree 

 with branches villous when young, and crenate-serrate 

 or entire elliptic-ovate to oblong-ovate Ivs., or those on 

 the vigorous shoots somewhat doubly serrate: calyx
