ROSACE^E 411 



villose early in the season, becoming glabrous, usually about \' in length; leaves at the end 

 of vigorous shoots usually elliptic, acute, coarsely serrate, frequently 3' long and 1^' wide, 

 with stouter and more broadly winged petioles. Flowers f'-l' in diameter, on slender 

 pedicels, in broad many-flowered glabrous corymbs; calyx-tube broadly obconic, glabrous, 

 the lobes elongated, linear-lanceolate, entire or occasionally slightly dentate; stamens 

 20; anthers large, bright rose color; styles tw r o or three, surrounded at base by con- 

 spicuous tufts of white hairs. Fruit ripening late in October or in November, on slender 

 pedicels about |' long, in few-fruited drooping clusters, short-oblong, green tinged with 

 dull red, \' long, with only slightly enlarged erect and incurved calyx-lobes mostly decidu- 

 ous before the fruit ripens; flesh thin, green, dry and hard; nutlets 2 or 3, with a high 

 rounded ridge, \' long. 



A tree, 15-20 high, with a trunk 8'-10' in diameter, covered with dark scaly bark, small 

 spreading branches forming a broad open irregular head, and nearly straight dull chestnut- 

 brown branchlets gray-brown in their second year, and unarmed or sparingly armed with 

 stout straight chestnut-brown spines l^'-lf long. 



Distribution. Rich upland woods near Fulton, Hemstead County, southern Arkansas; 

 Chopin, Natchitoches Parish, near Winn, Winnfield Parish, and Lake Charles, Calcasieu 

 Parish, Louisiana; in the neighborhood of Marshall, Harris County, Texas.

Leaves oblong-obovate, acute or rounded at apex, gradually narrowed and cuneate at

and lustrous above, dull and paler below, I'-l j' long, and \'-\' wide, with a slender midrib, 

 and primary veins mostly within the parenchyma; petioles slender, about \' in length; 

 leaves at the end of vigorous shoots broad-obovate, rounded or abruptly short-pointed at 

 apex, thicker, more coarsely serrate, often 1^' long and 1' wide. Flowers \'-\' in diameter, 

 on slender pedicels, in compact few-flowered glabrous corymbs; calyx-tube broadly ob- 

 conic, glabrous, the lobes oblong-ovate, gradually narrowed and acuminate, entire, sparingly 

 villose on the inner surface; stamens 20, small, pale rose color; styles 2 or 3, surrounded 

 at base by clusters of white hairs. Fruit ripening in October, on slender pedicels about \' 

 in length, in few-fruited clusters, short-oblong to slightly obovoid, crimson, lustrous, 

 i'-' long, with spreading calyx-lobes mostly deciduous from the ripe fruit; nutlets 2 or 3, 

 obovoid, acute at apex, rounded at base, prominently ridged on the back, \ r long. 



A slender tree, 20 -25 high, with a tall trunk 4 '-6' in diameter, with dark red-brown bark 

 covered with small closely appressed scales, smooth slender drooping branches forming a 

 broad open head, and slender bright red-brown pendulous branchlets becoming gray in 

 their second year, and armed with straight slender dark chestnut-brown lustrous spines
