TREES OF NORTH AMERICA 



45. Crataegus blanda Sarg. 



Leaves oval to rhombic, acute or acuminate, and occasionally slightly lobed toward the 

 apex, broadly cuneate or concave-cuneate at the entire base, coarsely crenately serrate 

 above the middle with gland-tipped teeth, coated with soft pale hairs when they unfold, 

 fully grown when the flowers open about the 1st of May, and then membranaceous, dark 

 green and lustrous above and glabrous below with the exception of large axillary tufts of 

 snow-white tomentum, and at maturity subcoriaceous, yellow-green and lustrous on the 

 upper surface, paler on the lower surface, l|'-2' long, and I'-l^' wide, with a slender mid- 

 rib, and 2 or 3 pairs of thin primary veins extending obliquely toward the end of the leaf;

petioles slender, at first villose along the upper side, soon becoming glabrous, f'-l' in 

 length; leaves at the end of vigorous shoots often broadly ovate, rounded at base, more 

 deeply lobed above the middle, 2'-2|' long, and l|'-2' wide. Flowers 1' in diameter, on 

 slender elongated pedicels, in broad many-flowered corymbs, with linear entire bracts 

 and bractlets; calyx-tube broadly obconic, glabrous, the lobes gradually narrowed from a 

 broad base, acuminate, entire or obscurely dentate, glabrous; stamens 20; anthers canary- 

 "yellow ; styles 5. Fruit ripening about the middle of October, on slender pedicels, in many- 

 fruited drooping clusters, subglobose to short-oblong, bright orange-red, \' in diameter; 

 calyx prominent, with spreading lobes usually deciduous from the ripe fruit; nutlets 5, 

 thin, narrowed at the ends, deeply grooved on the back, \' long. 



An unarmed tree, 25-30 high, with a tall trunk 10'-12' in diameter, covered with dark 

 brown or nearly black bark divided by shallow fissures and broken on the surface into small 

 plate-like scales, stout ascending branches forming a broad irregular head, and nearly 

 straight glabrous branchlets dark orange-green at first, becoming dull red-brown during 

 their first season and darker brown the following year. 



Distribution. Dry uplands and low rolling hills near Fulton, Hempstead County, 

 Arkansas. 



46. Crataegus velutina Sarg. 



Leaves ovate to obovate, acute or rounded at apex, gradually narrowed and cuneate at 

 the entire base, and sharply often doubly serrate with straight glandular teeth, more than 

 half grown when the flowers open at the end of April and then covered above by short 

 white hairs and below with hoary pubescence, and often furnished with axillary tufts of 

 white tomentum, and at maturity glabrous, smooth and lustrous on the upper surface and 

 covered on the lower surface with matted pale hairs, If -2' long, and H'-2' wide, with a 

 thin midrib and primary veins; petioles slender, thickly covered early in the season with
