the lobes short, acute, very coarsely glandular-serrate, glabrous or slightly villose; 

 stamens 20; anthers large, pale yellow; styles 5. Fruit ripening at the end of Octo- 

 ber and falling gradually at the end of several weeks, on stout villose pedicels, in 

 few-fruited drooping clusters, oblong or rarely obovate, full and rounded and slightly 

 tomentose at the ends, bright crimson, very lustrous, marked by few large dark dots, 

 I'-l' long, about f thick; calyx little enlarged, with small linear-lanceolate coarsely 

 glandular-serrate erect and persistent lobes; flesh thick, yellow, subacid; nutlets 

 5, small in comparison to the size of the fruit, thin, rounded or slightly and irregu- 

 larly ridged on the back, ^' long. 



A tree, 20 high, with a tall straight stem, thick'slightly ascending wide-spreading 

 branches forming a broad open irregular head, and stout branchlets dark green and 

 covered when they appear with long pale hairs, becoming orange-brown, glabrous, 

 and very lustrous in their first winter, and unarmed, or armed with occasional 

 straight light chestnut-brown shining spines gradually narrowed from broad bases, 

 ^4' in length. 



Distribution. Bottom-lands of the White River near Newport, Arkansas; hardy 

 as far north as eastern Massachusetts, and unsurpassed late in the autumn in the

59. Crataegus gravida, Beadl. 



Leaves broadly ovate, acute, rounded or truncate at the base, and coarsely and 

 often doubly serrate, with incurved glandular teeth, and slightly incisely lobed, 

 when they unfold roughened above by short pale hairs and hoary-tomentose below,

 thin, firm, dark green, lustrous and scabrate above, paler and pubescent or pu- 

 berulous below, particularly on the slender midribs and veins, l|'-2^' long, about 



ly wide, turning in the autumn yellow, orange, and brown; their petioles slender, 

 tomentose, about ^'-V long. Flowers about f ' in diameter, on short hoary-tomen- 

 tose pedicels, in narrow crowded many-flowered compound hoary-tomentose corymbs; 

 calyx-tube broadly obconic, covered with matted pale hairs, the lobes gradually nar- 

 rowed from broad bases, acuminate, glandular-serrate, villose; stamens 20; styles 5.
