TREES OF NORTH AMERICA 



flesh yellow; nutlets 5, broad and rounded at the ends, ridged and often grooved on the 

 back, about ?' long. 



A tree, usually 15-20 but occasionally 25 high, with a tall straight trunk often but- 

 tressed at base, frequently armed with numerous large much-branched spines sometimes 

 6'-8' long, stout wide-spreading branches forming a handsome flat-topped symmetrical 

 head, and branchlets tinged with red and villose with long matted silky white hairs when 

 they first appear, soon puberulous, and dull reddish brown, becoming gray in their second 

 year, and furnished with stout lustrous spines 2'-3' long. 



Distribution. Hillsides in rich soil in the foothill region of the southern Appalachian 

 Mountains from southwestern Virginia to central Georgia and westward to northeastern 

 Mississippi and middle Tennessee; in central Alabama; ascending to altitudes of 2500 above 

 the sea. 



29. Crataegus amnicola Beadl. 



Leaves obovate, oval or ovate, acute or acuminate at apex, gradually narrowed and 

 concave-cuneate at the entire base, coarsely sometimes doubly serrate above with straight 

 or incurved glandular teeth, and incisely lobed above the middle with short acute or acu-

ruinate lobes, deeply tinged with red and covered with short pale mostly caducous hairs 

 when they unfold, about half grown and sparingly villose on the midrib and veins when the 

 flowers open late in April or early in May, and at maturity subcoriaceous, bright green, 

 glabrous, 1|'-1|' long, and I'-l^' wide; turning in the autumn yellow, orange, red, and 

 brown; petioles slender, sparingly villose early in the season, becoming glabrous, sometimes 

 slightly glandular, \'-\' in length: leaves at the end of vigorous shoots sometimes 2' long 

 and 1|' wide. Flowers about f in diameter, on elongated slender slightly villose pedicels, 

 in narrow many-flowered villose corymbs; calyx-tube narrowly obconic, glabrous or with a 

 few scattered hairs at the base, the lobes narrow, acuminate, glandular-serrate, glabrous; 

 stamens 20; anthers nearly white; styles 3-5. Fruit on slender elongated glabrous pedicels, 

 in drooping few-fruited clusters, subglobose, dull red, about % in diameter; calyx enlarged, 

 with elongated coarsely serrate reflexed conspicuous lobes; flesh yellow, thin, and firm: 

 nutlets 3-5, rounded or slightly grooved on the back, nearly \' long. 



A tree, occasionally 25 high, with a trunk 8'-12' in diameter, spreading or ascending 

 branches forming a large wide head, and branchlets villose at first with long matted white 

 hairs, soon glabrous, becoming orange-brown and ultimately ashy gray, and unarmed, 

 or armed with stout spines l|'-2' long. 



Distribution. Low moist woods and the borders of streams, southeastern Tennessee, 

 northwestern Georgia, and northeastern Alabama; common.
