obconic, coated with long matted pale hairs, the lobes broad, acuminate, very coarsely 

 glandular-serrate with large stipitate bright red glands, glabrous on the outer surface except 

 at the base, villose on the inner surface; stamens 10; anthers rose color; styles 2 or usually 

 3. Fruit ripening early in October and persistent on the branches until after the beginning 

 of winter, on stout bright red pedicels, in few-fruited drooping villose clusters, globose, 

 scarlet, lustrous, marked by occasional dark dots, more or less villose at the ends, \' in 

 diameter; calyx prominent, with a short villose tube, and spreading lobes gradually nar- 

 rowed from a broad base, sparingly glandular-serrate or nearly entire, villose, mostly de- 

 ciduous before the fruit ripens; flesh thin, yellow, dry and mealy; nutlets 2 or 3, \' long, 

 broad and thick, rounded at the ends, the ventral cavities broad and deep. 



Fig. 499 



A tree, rarely more than 18 high, with a trunk 4'-5' in diameter, covered with thin close 

 bark broken on the surface into pale plate-like scales, and divided into several long erect 

 and spreading slender branches forming a wide open-topped head, and stout somewhat 

 zigzag branchlets covered at first with scattered pale caducous hairs, bright orange-brown 

 and lustrous during their first season, becoming dark brown in their second year and ulti- 

 mately ashy gray, and armed with numerous slender straight or curved bright chestnut- 

 brown shining spines l|'-3' long. 



Distribution. Open woods along the gravelly banks of small streams in Stark and Peoria 

 Counties, Illinois; not common. 



148. Cratsegus integriloba Sarg. 



Leaves broad-obovate, oval or rhombic, acute, gradually or abruptly narrowed below the 

 middle, entire at the cuneate base, coarsely doubly serrate above with spreading glandular 

 teeth, and irregularly divided into numerous short acute or acuminate lobes, coated in early 

 spring with soft pale caducous hairs, nearly fully grown when the flowers open during the 

 first week in June, and at maturity glabrous, thin and firm in texture, dark green and lus- 

 trous on the upper surface, pale yellow-green on the lower surface, \\'-%! long, and I'-l^' 

 wide, with a slender midrib often dark red at the base, and 4-6 pairs of slender primary 

 veins deeply impressed on the upper side; petioles stout, more or less broadly winged toward 

 the apex, at first puberulous, soon glabrous, often red on the lower side, \'-\' in length; 

 leaves at the end of vigorous shoots more coarsely serrate, more deeply lobed, often 3' long 

 and 2|' wide, with stout broadly winged petioles. Flowers f ' in diameter, on long slen- 

 der villose pedicels, in broad open crowded villose corymbs; calyx-tube broadly obconic, 

 coated toward the base with long matted white hairs and glabrous above, the lobes linear-
