der hairy pedicels, in crowded densely villose usually 10-12-flowered corymbs; calyx-tube 

 narrowly obconic, glabrous or covered with long matted pale hairs, the lobes lanceolate, 

 acute, glabrous, usually glandular-serrate, often tinged with red toward the apex; stamens 

 20; anthers bright rose color; styles 1-3. Fruit ripening in October and persistent on the 

 branches until the beginning of winter, short-oblong, bright scarlet, |' long; calyx prom-

 lets 1-3, rounded at the ends, about $' long. 



A tree, occasionally 20 high, with a trunk rarely 6'-8' in diameter, branches spreading 

 nearly at right angles and forming a wide irregular open head, and slender more or less 

 zigzag of ten -contorted branchlets covered when they first appear with long pale hairs, light 

 red or pale orange-brown and usually puberulous in their first winter, ultimately light 

 brown or ashy gray, and armed with stout straight chestnut-brown spines l'-l|' long. 



Distribution. Borders of streams and swamps or in hummocks in Pine-barrens in the 

 coast and Piedmont regions of the south Atlantic States from southeastern Virginia to 

 Georgia; in western Florida south to Lafayette County (near Old Town), north-central and 

 southern Alabama, Louisiana and the coast region of Texas to the valley of the lower Colo- 

 rado River (low woods, Peyton's Creek, Matagorda County), and through Arkansas to 

 eastern Oklahoma (Page, Le Flore County) and to southeastern Missouri; most abundant 

 and of its largest size in southern Arkansas and western Louisiana.
