TREES OF NORTH AMERICA 



slender, glandular, slightly winged at the apex, at first villose, usually becoming 

 glabrous, often dark red toward the base, |'-1' long; on vigorous shoots oblong-ovate, 

 oval or often nearly orbicular, more deeply lobed and frequently 2^'-3' long. 

 Flo"wers -^'-f ' in diameter, on slender pedicels, in broad loose compound many- 

 llowered villose or tomentose corymbs; calyx-tube broadly obconic, tomentose or 

 villose, the lobes gradually narrowed from broad bases, acute, coarsely glandular- 

 serrate, glabrous or villose, often bright red toward the apex; stamens 10; anthers 

 small, pale yellow; styles 3 or 4. Fruit ripening and falling late in October, on 

 short stout pedicels, in drooping many-fruited pilose clusters, subglobose but occa- 

 sionally rather longer than broad, dark crimson, marked by scattered dark dots 

 about ^' in diameter; calyx enlarged, conspicuous, the lobes bright red on the upper 

 side, toward the base, wide-spreading or erect; flesh thin, yellow, dry and sweet; 

 nutlets 3 or 4, full and rounded at the ends, prominently ridged on the back, with a 

 high grooved ridge, about \' long. 



A bushy tree, occasionally 20 high, with a short trunk 8'-10' in diameter, cov- 

 ered with dark red-brown scaly bark, stout ascending branches forming a broad 

 round-topped symmetrical head, slender branchlets light green and covered with long 

 matted pale hairs when they first appear, soon becoming glabrous, bright red-brown 

 and lustrous during their first year, and ultimately ashy gray, and armed with many 

 stout straight or slightly curved chestnut-brown shining spines I'-l^' long. 



Distribution. Slopes of low hills and the high banks of salt marshes usually in 

 rich well drained soil; Newfoundland to Connecticut, usually in the neighborhood 

 of the sea, and through the valley of the St. Lawrence River to western Quebec. 

 A form, var. rotundifolia, Sarg., with glabrous young branchlets, leaves, and corymbs, 

 is a common New England shrub ranging southward to eastern Pennsylvania. 



91. Crataegus Jonesae, Sarg. 



Leaves elliptical to ovate, acute, gradually narrowed or broadly cuneate at the 

 entire base, coarsely doubly serrate above, with spreading or incurved teeth tipped 

 with deciduous dark red glands, and usually divided above the middle into 2 or 3 



pairs of short acute or acuminate lobes, more than half grown when the flowers open 

 during the first week of June, and then membranaceous and coated with soft pale
