of pale tomentum. Fruit ripening late in August or early in September, on slender 

 pubescent pedicels, in few-fruited clusters, subglobose to short-oblong, light red, 

 puberulous toward the ends, about ' in diameter; calyx prominent, with reflexed 

 closely appressed lobes tomeutose at the base; flesh thin, yellow, subacid; nutlets 

 3-5, broad, rounded at the ends, ridged on the back, with a broad low ridge, dark 

 brown, \' long. 



A tree, 20-25 high, with a short trunk a foot in diameter, heavy ascending 

 branches forming a broad irregular head, and stout zigzag branchlets at first hoary- 

 tomentose, dark red-brown and pubescent during their first summer, becoming 

 darker colored and glabrous the following season, and armed with thick or thin 

 nearly straight dark red-brown ultimately gray spines l^'-2' long. 



Distribution. Dry sand hills near Aiken and Trenton, South Carolina, and 

 abundant at Sumnierville, near Augusta, Georgia. 



** Stamens 10 ; anthers yellow. 



115. Crataegus aprica, Beadl. 



Leaves broadly obovate, oval, or rhomboidal, acute and short-pointed or rounded 

 and often somewhat lobed at the apex, gradually or abruptly narrowed and cuneate 

 at the entire base, and serrate usually only above the middle, with small incurved teeth 

 terminating in conspicuous rose-colored ultimately dark red persistent glands, when 

 they unfold deep orange color, roughened above by short pale appressed hairs and 

 sparingly villose below, particularly along the slender midribs and remote primary 

 veins, nearly fully grown when the flowers open about the 10th of May, and at ma- 

 turity thick and firm, glabrous, very smooth, dark yellow-green on the upper surface, 

 paler on the lower surface, I'-l^' long, and 1' wide; their petioles stout, conspicuously 



glandular, more or less winged toward the apex, at first villose, ultimately nearly 

 glabrous, usually bright red on the lower side toward the base after midsummer, 

 about \' long; on vigorous shoots often nearly orbicular, frequently more deeply 

 lobed, l'-2' long and wide, with stout broad-margined petioles, and foliaceous lunate 

 stipules. Flowers f in diameter, on slender villose pedicels, in small 3-6-flowered 

 compact simple corymbs; calyx-tube broadly obconic, villose at the base, glabrous
