Mountain plants -- Canadian Rockies (B.C. and Alta.)
Smooth and simple, 3—6 inches high, from an extensively creeping
rhizome, with a few fibrous roots at each node. Leaves 4—8, bright
green and shining on both surfaces, ovate-lanceolate, acute, 1—2
inches long, the upper merely sessile, the lower clasping at the base.
Flowers few, about ¼ of an inch in width, stellate and solitary on very
slender, curved stalks about ⅜ of an inch long in the axils, at the
backs of the upper leaves; sepals and petals deep wine-colour at the
base, with yellowish-green reflexed tips; stamens 6, anthers ovoid,
2-lobed, yellow and prominent, slightly below the centre of the sepals
and petals; ovary broadly urn-shaped; style none; berry nearly globose
at maturity and bright red.
Known only in the Selkirks where it occurs in colonies of considerable
size in the rich woods at Glacier; flowering in the middle of June.
[Sidenote: =Disporum Oreganum= (S. Wats.) B. and H. _Disporum._]
Stem 1—3 feet high, much branched and finely hairy above. Leaves
yellowish-green when young, becoming darker with age, ovate or oblong,
acuminate, distinctly heart-shaped at the base, 2—4 inches long,
hairy, especially beneath. Flowers appearing as the leaves unfold
greenish-yellow or nearly white, drooping 1 or 2 together at the ends
of the branches; sepals and petals spreading half an inch or more in
length, lanceolate and narrowed at the base into a broad claw; stamens
exserted, anthers yellow; style simple, larger than the stamens; berry
ovate, half an inch in diameter, smooth or nearly so when ripe, bright
red and few-seeded.
In moist rich woods throughout the region, most abundant on the
western slope of the Rockies and in the Selkirks; flowering in June.
[Sidenote: =Disporum majus= (Hook). Britton. _Large Flowered Disporum._]
Plant 1—2 feet high with few branches, hairy when young. Leaves ovate
or oblong-lanceolate, acute or short, acuminate, rounded at the base.
Flowers greenish-yellow or nearly white, 1—3 together at the ends of
the branches; sepals and petals not spreading, half an inch or less in
length, narrowly oblong or oblanceolate, stamens about equalling the
sepals and petals; style slightly longer than the stamens, 3-cleft;
berry a little less than half an inch in diameter, depressed, globose,
and roughened with short papillæ.
In rich woods, most abundant on the eastern slopes of the Rockies;
flowering early in June.
