TREES OF NORTH AMERICA 



outer, puberulous on the inner surface; stamens 20; anthers almost white; styles 

 3-5, surrounded at the base by a broad ring of snow-white tomentum. Fruit ripen- 

 ing and falling late in August or early in September, subglobose or oval, orange-red 

 or red and orange, about ' long; calyx little enlarged, the lobes puberulous on the 

 upper side and reflexed; flesh thick and soft; nutlets 3-5, full and rounded at the 

 base, narrowed and rounded at the apex, rounded and ridged on the back, with a 

 broad low rounded ridge, about T 5 ^' long and T 8 ^' wide. 



A tree, 20-25 high, with a trunk sometimes a foot in diameter, covered with 

 dark rough often black bark, stout spreading or ascending branches, and thick dull 

 red-brown ultimately dark gray or nearly black branchlets armed with straight 

 rather stout spines I'-l^' long. 



Distribution. Eastern central Alabama; common near Phoenix and Gerard. 



114. Crataegus dispar, Beadl. 



Leaves broadly ovate or orbicular, 3-nerved, acute or rounded at the apex, gen- 

 erally narrowed and cuneate or concave-cuneate at the glandular entire base, serrate 

 or doubly serrate above, with straight or incurved glandular teeth, and mostly divided 



above the middle into short acute lobes, when they unfold coated with long matted 

 white hairs most abundant on the lower surface, more than half grown when the 

 flowers open about the middle of April and then blue-green and villose above 

 and tomentose below, and at maturity thin but firm in texture, blue-green and gla- 

 brous on the upper surface, pale and slightly pubescent on the lower surface, usually 

 about 1' long and f '-!' wide, turning red, yellow, or brown in the autumn; their 

 petioles slender, tomentose, becoming pubescent or villose, glandular, slightly wing- 

 margined above, usually about ^' long ; stipules lunate, coarsely glandular-serrate, 

 ^f'-|' long, caducous; on vigorous shoots broadly ovate or suborbicular, full and 

 rounded at the broad base, coarsely serrate, and often deeply divided above the 

 middle into 3 wide acute lobes broader than long. Flowers about -| ' in diameter, 

 on slender hoary-tomentose pedicels, in simple 3-7-flowered corymbs, with narrow 

 obovate acute glandular bracts and bractlets; calyx-tube narrowly obconic, coated 

 with hoary tomentum, the lobes narrow, acute, glandular-serrate, with minute bright 

 red glands, tomentose on the outer surface below the middle, glabrous above, tomen- 

 tose on the inner surface; stamens 20; styles 3-5, surrounded at the base by a ring
