Mountain plants -- Canadian Rockies (B.C. and Alta.)
[Sidenote: =Rubus parviflorus= Nutt. _Salmon-berry._]
Stems shrubby, 3—8 feet high, smooth or more or less glandular-hairy.
Leaves round-cordate in outline, palmately 3—5-lobed, the lobes acute
or acutish, rarely acuminate, coarsely and unequally serrate. Flowers
few, 1—2 inches broad, white, in corymbose, terminal heads, calyx lobes
tipped with a long slender appendage.
Borders of woods, and in thickets among rocks, throughout the region,
but most abundant in the Selkirks; flowering in June and July.

[Sidenote: =Rubus strigosus= Michx. _Wild Red Raspberry._]
Stems shrubby, biennial, 18 inches to 4 feet high, usually densely
clothed with weak glandular bristles or the older stems with small
hooked prickles. Leaves pinnately 3—5-foliate, leaflets ovate or
ovate-oblong, acuminate, sharply and irregularly serrate or slightly
lobed, rounded at the base, 1—3 inches long. Flowers ½ an inch broad
in a loose raceme on slender pedicels, curved in fruit; petals white,
ascending, about equalling the spreading acuminate sepals; fruit dark
red, sweet and very juicy.
The common red raspberry throughout the region in dry and rocky places;
flowering in June.
[Sidenote: =Dasyphora fruticosa= (L.) Rydb. _Shrubby Cinquefoil._]
Shrubby, much branched; stems erect or ascending, very leafy, 6 inches
to 3 feet high, the bark shreddy. Leaves pinnate with 5—7 oblong,
entire, acute leaflets, with long silky hairs and revolute margins.
Flowers bright yellow, ¾—1½ inches broad, usually solitary at the ends
of the branches.
A very abundant plant throughout the region, in swampy grounds,
gravelly river shores, on dry slopes and alpine meadows, flowering
throughout the summer.
[Sidenote: =Sibbaldia procumbens= L. _Sibbaldia._]
Stems densely tufted, decumbent or creeping, 1—4 inches long.
Leaves 3-foliate, leaflets wedge-shaped, 3—5-toothed at the apex
with scattered hairs on both sides. Flowers ¼ of an inch broad,
greenish-yellow; petals very small, not exceeding the calyx.
Frequent throughout the region on rocks, usually in dry, exposed
situations at elevations varying from 4000 to 10,000 feet; flowering
during June and July.
[Sidenote: =Fragaria glauca= (S. Wats.) Rydb. _Wild Strawberry._]
Plant spreading, 3—6 inches tall, hairy, forming new plants by the
running stems after flowering. Leaves tufted from the root, very
hairy, palmately 3-foliate; leaflets obtuse, strongly serrate, the
teeth gland-tipped; lateral leaflets ovate, oblique on the inside,
shorter than the terminal one; terminal leaflet broadly ovate with a
wedge-shaped base. Flowers white, ¾ of an inch broad; petals slightly
longer than the sepals, borne on a scape about ⅓ longer than the
leaves. Fruit ovoid, rather small.
On grassy banks and roadsides throughout the Rockies; flowering in late
May and early June.
