ous dark red glands, and usually divided above the middle into 2 or 3 pairs of short acute 

 or acuminate lobes, more than half grown when the flowers open during the first week of 

 June, and then membranaceous and coated with soft pale hairs most abundant on the under 

 side of the midrib and principal veins, and at maturity thick and coriaceous, dark green 

 and lustrous on the upper surface, pale and puberulous on the lower surface, 3 '-4' long and 

 2'-3' wide, with a stout midrib, 4-6 pairs of primary veins and conspicuous secondary 

 veinlets; petioles stout, more or less winged toward the apex, villose, ultimately glabrous, 

 tinged with red below the middle, l|'-2' in length, after midsummer often twisted at base, 

 bringing the lower surface of the leaf to the light; leaves at the end of vigorous shoots 

 usually more coarsely serrate and much more deeply lobed, with broadly winged petioles, 

 and falcate coarsely glandular-serrate stipules sometimes 1' in length. Flowers 1' in diam- 

 eter, on long slender pedicels, in broad loose lax many-flowered tomentose corymbs; calyx-

tube narrowly obconic, tomentose, the lobes abruptly narrowed from a broad base, long, 

 acute, entire, villose; stamens 10; anthers large, rose color; styles 2, or generally 3, sur- 

 rounded at base by a narrow ring of pale tomentum. Fruit ripening usually early in 

 October, on slender elongated pedicels, in broad many-fruited drooping glabrous or puber- 

 ulous clusters, short-oblong to oblong-obovoid, rounded at the ends, bright carmine-re^, 

 marked by occasional large dots, f '-!' long, and f ' in diameter; calyx conspicuous, with en- 

 larged and elongated closely appressed lobes; flesh thick, yellow, sweet and mealy; nutlets 

 3 or rarely 2, thick, narrowed and acute at base, full and broad at apex, rounded and 

 ridged on the back with a high broad ridge, about -/g ' long. 



A tree, sometimes 20 high, with a tall trunk often a foot in diameter, covered with dark 

 brown scaly bark, ascending or spreading branches forming a broad open irregular head, 

 and stout branchlets tomentose early in the season, becoming orange-brown, glabrous and 

 very lustrous during their first summer, and light gray the following year, and armed with 

 stout straight or curved chestnut-brown shining spines 2'-3' long and usually pointed 

 toward the base of the branch.

 ericton, York County, New Brunswick; Riviere du Loup, Kamouraska County, Province 

 of Quebec (Brother Victorin).
