ROSACE^E 447 



on long thin slender glandular petioles at first villose, ultimately glabrous, from I'- 

 ll' long; on vigorous shoots sometimes truncate or slightly cordate at the base and 

 frequently 3' long and broad. Flowers about f ' in diameter, on stout hairy pedicels, 

 in many-flowered compound villose corymbs; calyx-tube narrowly obconic, villose, 

 particularly toward the base, the lobes narrow, acuminate, coarsely glandular-serrate, 

 villose on both surfaces or only on the inner surface; stamens 10, occasionally 5-10; 

 anthers small, purple; styles 3-5, surrounded at the base by conspicuous tufts of pale 

 tomentum. Fruit ripening and falling late in September or early in October, on stout 

 pedicels, in erect villose mostly few-fruited clusters, short-oblong, dark dull red, 

 marked by few dark dots, villose at the ends, with long scattered pale hairs, ' long 

 and f thick; calyx little enlarged, the lobes gradually narrowed from broad bases, 

 acuminate, glandular-serrate, often erect; flesh thick, yellow, dry and acid, with a dis- 

 agreeable flavor; nutlets 3-5, rounded and slightly ridged on the back, ' long. 



A tree, occasionally 25 high, with a tall trunk 10'-12' in diameter, with thin bark 

 readily separating into large flakes covered with small loose dark red-brown scales, 

 stout branches forming a wide symmetrical head, and slightly zigzag branchlets at 

 first dark green and villose, soon becoming glabrous, chestnut-brown and lustrous, 

 bright orange-brown during their second year, and armed with thick straight or 

 somewhat curved chestnut-brown spines often 1^' long. 



Distribution. Southern New Hampshire, through southern Vermont to western 

 Massachusetts, western New York and Ontario, and through the southern peninsula 

 of Michigan to northeastern Illinois. 



79. Crateegus lobulata, Sarg. Red Haw. 



Leaves oval to oblong-ovate, acute at the apex, broadly cuneate or rounded at the 

 entire base, sharply and often doubly serrate above, with straight glandular teeth, 



and deeply divided into numerous narrow acute or acuminate lobes spreading or 

 pointing to the apex or to the base of the leaf, when they first appear and until after 

 the opening of the flowers during the last week in May covered above with short 

 soft pale hairs and slightly pubescent below along the slender midribs and thin 

 primary veins arching to the points of the lobes, and at maturity thin, dark yellow- 

 green and glabrous on the upper surface, paler on the lower surface, with occa- 

 sional short white hairs toward the base of the midribs, 2^'-3^' long, and 2'-2' wide;
