A tree, with exceedingly bitter bark and leaves, thirty to forty feet in height, with a trunk twelve 
to fourteen inches in diameter, dividing into a number of slender rather upright branches which form a 
symmetrical oblong head; or often a shrub with spreading stems three to ten feet tall. The bark of 
the trunk is a quarter of an inch thick, with a generally smooth dark brown surface marked by horizon- 
tal light gray interrupted bands, and by rows of oblong orange-colored lenticular excrescences. The 
branches, when they first appear, are coated with pale pubescence, and are slender and flexible; in their 
first winter they are covered with dark red-brown bark marked by many minute dots, and in their second 
season, when they develop short lateral branchlets, with bright red bark conspicuously marked by large 
pale lenticels. The winter-buds are acute, an eighth of an inch long, and covered with chestnut-brown 
scales often slightly scarious on the margins ; those of the inner ranks are acuminate at maturity, glandular- 
serrate above the middle, scarious, and nearly half an inch in length, with bright red tips. The leaves 
are oblong-obovate to oblanceolate, rounded, and usually obtuse or sometimes acute at the apex, the two 
forms appearing occasionally on the same branch; they are. narrowed at the base, which is generally 
furnished with one or two and sometimes three or four large dark glands, and are serrate, the minute 
teeth tipped with short subulate glandular points; when they unfold they are puberulous or pubescent 
on the lower surface and slightly viscid, and when fully grown are glabrous or pubescent on the 
lower surface, one to three inches long and from one third of an inch to one and a half inches broad, 
dark green above, paler below, and borne on short stout grooved and usually pubescent petioles. The 
stipules are lanceolate-acuminate, glandular-serrate, and early deciduous: The flowers, which appear 
when the leaves are about half grown, at the end of April at the level of the ocean or as late as the 
end of June at high elevations, and which when expanded vary from one third to one half of an inch 
in diameter, are produced in six to twelve-flowered glabrous or pubescent corymbs an inch to an inch 
and a half in length, on slender pedicels from the axils of foliaceous glabrous glandular-serrate bracts. 
The calyx-tube is obconic, glabrous, or puberulous on the outer surface, and bright orange-colored in 
the throat, with shért lobes rounded or emarginate or somewhat cleft at the apex, sometimes slightly 
glandular on the margins, and reflexed at maturity. The petals are white faintly tinged with green, 
obovate, rounded or emarginate at the apex, and contracted below into short claws. The ovary? and 
filaments are glabrous, and the style, which enlarges into a stout clavate stigma, is sometimes slightly 
glandular. The fruit, which ripens from June to August, is globose, from one fourth to one half of an 
inch in diameter, and more or less translucent, and when first fully grown is bright red, becoming 
1 In northeastern Idaho Professor Greene found bipistillate flowers of this species, with two drupes from each flower (Garden and 
Forest, iv. 243).
