veins slightly villose below, conspicuous secondary veins and reticulate veinlets; late in 

 October and in November turning bright clear yellow; petioles stout, deeply grooved, more 

 or less winged toward the apex, glandular with minute usually deciduous dark glands, at 

 first tomentose, ultimately glabrous or puberulous, turning dark red after midsummer, 

 l'-lf in length; leaves at the end of vigorous shoots broad-ovate, rounded or truncate at 

 base, often 4' long and 3' wide.. Flowers nearly 1' in diameter, on short stout pedicels, in 

 broad- rather compact many-flowered villose corymbs; calyx-tube narrowly obconic, coated 

 with long matted pale hairs, the lobes short, acute, coarsely glandular-serrate, glabrous or 

 slightly villose; stamens 20; anthers large, pale yellow; styles 5. Fruit ripening at the end 

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

 few-fruited drooping clusters, short-oblong or rarely obovoid, rounded and slightly tomen- 

 tose at the ends, bright crimson, very lustrous, marked by few large dark dots, f'-l' long, 

 about f in diameter; calyx little enlarged, with small linear-lanceolate coarsely glandular- 

 serrate erect and persistent lobes; flesh thick, yellow, subacid; nutlets 5, small in com-

 *' 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 

 early in the season with long pale hairs, becoming orange-brown, glabrous, and very lus- 

 trous in their first winter, and unarmed or armed with occasional straight light chestnut- 

 brown shining spines, \'-%' in length. 



Distribution. Bottom-lands of the White River near Newport, Jackson County, Arkan-

Leaves broad-ovate, acute, rounded or truncate at base, coarsely and often doubly

 glabrous, about |'-1' in length; leaves at the end of vigorous shoots oblong-ovate to nearly
