mountainous portions of northern Idaho and western Montana (on 
Pacific coast and north of United States boundary), reaching elevations 
from 3,000 to 4,000 feet; but at high altitndes reduced toashrub. Re- 
aneabls for the coe of its growth, covering quitelarge areas. Va- 
riety mollis (Brewer) is the form commonly met with in the northern 
Rocky Mountain region. ‘The timber is light, soft, and brittle. 
Description.—Leaves oblong-ovate, or lance-shaped, chiefly with a blant apes, ta- 
pering to a short stem; with small, rounded teeth on the margin, and woolly pubes- 
cence on the under surface. Fruit small, globular, red or blackish, with bitter astrin- 
gent taste; not edible; stone with a grooved ridge on one side. Bark much like that 
of the common cherry tree of cultivation. Notable for its slender, straight trunks. 
46,—WILD CHERRY. (Prunus Capuli, Cavanilles.) 
A rather small tree, growing in light, rich soil of canyon bottoms, 
and ranging through Arizona, New Mexico (western Texas, and south- 
ward), usually between 5 000 and 7,000 feet. It is a very prolific spe- 
cies, but does not attain its largest size in the United States ; commonly 
not more than 30 feet in height, with a trunk 3 to 10 inches in diame- 
ter. The wood is heavy and rather hard. 
Description.—Leaves 1 to 34 inches long, ovate to lance-shaped, sometimes with 
rather long tapering point; finely and sharply toothed on the margin ; smooth, paler 
on under surface. Very young shoots and leaf stalks downy. Fruit globular, 2 of an 
inch in diameter, dark red, with large stone and scanty flesh; edible. 
47.—WILD CHERRY. (Prunus Demissa, Walpers.) 
Chiefly a small shrub as met with on the western slopes of the Rocky 
Mountains of Montana. In its more westerly range on the Pacific coast 
it becomes farger, sometimes 30 feet in height, and 6 to 12 inches in 
diameter, usually preferring rich valleys. The wood is heavy, hard, 
but brittle. 
Discription.—Leaves ovate to oblong-ovate, tapering suddenly to a point, rounded 
or heart-shaped at the base; sharply toothed (teeth straight) on the margin; com- 
monly downy on the under side and dull green above. Fruit purplish or dark red, 
with sweetish-astringent taste; edible. 
48.—CHOKE-CHERRY. (Prunus Virginiana, Linn.) 
Chiefly a slender shrub, but sometimes a small tree 10 to 15 feet in 
height. A widely- distaparea species, occurring generally throughout 
the northern Recky Mountain region (also eastward and north of the 
United States boundary), usually preferring moist positions. The wood 
is ight and rather hard. 
Description.—Leaves thin, usually smooth and shiny above, paler beneath, 1 to 
nearly 5 inches long, mostly broad-ovate (wider near the top) to oblong, tapering 
suddenly to a short point at either end, sometimes heart-or wedge- shaped at the 
base; margin finely cut with sharp teeth (often of two sizes). Flowers (white) and 
fruit borne in a rather long cylindrical cluster (raceme); the latter when ripe to 
1 of an inch in diameter), dark red, very astringent, though w ith more or less pleas- 
ant taste,
