TREES OF NORTH AMERICA 



serrate lobes; flesh juicy, succulent, yellow; nutlets 2 or 3, about |' long and nearly 

 as broad, thin, full and rounded at the obtuse ends, rounded and obscurely ridged 

 on the back, the ventral cavities broad and deep. 



A tree, sometimes 20 high, with a short trunk C'-8' in diameter, covered with 

 gray scaly bark, erect branches forming a broad open head, and slender branchlets 

 at first hoary-tomentose, becoming bright red-brown and lustrous, and armed with 

 occasional stout straight or curved bright chestnut-brown spines 1^-2' long. 



Distribution. Low rich soil on the banks of streams in the Appalachian region 

 from Virginia to northern Georgia and eastern Tennessee. 



123. Crataegus Gaultii, Sarg. 



Leaves elliptical to suborbicular, acute or rounded at the apex, concave-cuneate 

 or rounded at the entire base, coarsely doubly serrate above, with straight glandular 

 teeth, and occasionally divided above the middle into short acute lobes, nearly fully 



grown when the flowers open at the end of May and then very thin, yellow-green 

 and sparingly villose above, pale and slightly pubescent below, and at maturity thin 

 but firm in texture, glabrous, dark dull green on the upper surface, pale on the lower 

 surface, 21'-3' long, 2'-2|' wide, with stout yellow midribs deeply impressed above, 

 and 6 or 7 pairs of primary veins extending obliquely to the points of the lobes; their 

 petioles stout, wing-margined to below the middle, villose on the upper side early in 

 the season, with matted white hairs, becoming nearly glabrous, I'-l' long. Flo"wers 

 I' in diameter, on long slender slightly villose pedicels, in broad many-flowered hairy 

 compound corymbs, with 3-flowered peduncles from the axils of the 2 upper leaves, 

 their bracts and braetlets linear, acuminate, glandular, mostly persistent until the 

 flowers open; calyx-tube narrowly obconic, glabrous, the lobes broad, acuminate, 

 coarsely glandular-serrate, glabrous on the outer, villose on the inner surface; sta- 

 mens 18-20; anthers pale pink; styles 2 or 3. Fruit ripening from the middle to 

 the end of September, on slender slightly hairy pedicels, in few-fruited drooping 

 clusters, subglobose to short-oblong, ^'-f long; calyx prominent, with spreading ap- 

 pressed coarsely serrate lobes; flesh thick, yellow, soft and juicy; nutlets 2 or 3, full 

 and rounded at the ends, about ^^' long and nearly as wide, full and rounded on the 

 back, with a high rounded ridge, the ventral cavities long, deep, and narrow.
