frequently divided into 2 or 3 pairs of short broad acute lateral lobes, when they 

 unfold deep bronze-red, slightly glandular and viscid, nearly fully grown when the 

 flowers open early in May, and then membranaceous and glabrous or occasionally 

 slightly pilose, and at maturity thick and firm, glabrous, yellow-green on the upper 

 surface, pale on the lower surface, l'-2^' long, l'-2' wide, with thin pale yellow mid- 

 ribs and 4-7 pairs of slender veins ; their petioles stout, glandular often to the base, 

 with bright red glands, slightly winged above, usually about ^' long; on vigorous shoots 

 often as broad as long, truncate or cordate at the base, and more coarsely dentate 

 and more deeply lobed. Flo"wers about ^' in diameter, on short slender pedicels, in 

 compact 4-10-flowered compound corymbs; calyx-tube broadly obconic, the lobes 

 abruptly narrowed from broad bases, acute or rounded at the apex, entire or obscurely 

 and irregularly glandular-serrate above the middle; stamens 10; anthers large, pale 

 yellow; styles 3-5, surrounded at the base by a broad thick ring of hoary tomentum. 



Fruit ripening and falling early in October, on short stout pedicels, in few-fruited 

 erect clusters, depressed-globose, more or less angled, yellow-green flushed with 

 russet-red, marked with small dark dots, usually about 1' in diameter; calyx promi- 

 nent, the large spreading lobes often deciduous before the fruit ripens; nutlets 3-5, 

 acute or acuminate at the apex, rounded at the narrow base, prominently ridged on 

 the back, with a high rounded ridge, about \' long. 



A tree, occasionally 20 high, with a tall straight trunk 6'S' in diameter, some- 

 times armed with long gray compound spines, stout ascending branches forming a 

 narrow open irregularly or occasionally a round-topped head, and glabrous branchlets 

 furnished with many thin nearly straight light chestnut-brown spines l^'-2' long; or 

 more often a shrub, with numerous stems. 



Distribution. Banks of streams, the borders of fields and upland woods in the 

 southern Appalachian foothill region from southern Virginia to northern Georgia and 

 Alabama, southeastern Kentucky, and Tennessee, sometimes ascending to elevations 

 of 3000 above the sea.
