Mount Rainier Part 28

A small "bitter-cress," not rare along rills at 5,000 feet elevation.

=Erysimum asperum= (Nuttall) De Candolle.

A yellow-flowered plant much like a wallflower, rare at 6,000 feet alt.i.tude. It occurs also in loose rock near Interglacier.

=Smelowskia ovalis= Jones.

A small, white-flowered, canescent plant, interesting because it ascends Mount Rainier higher than any other flowering plant. Common from 8,000 to 10,000 feet alt.i.tude. One specimen was collected quite at the base of "The Sphinx."

=FUMARIACEAE.= (Bleeding-heart Family.)

=Corydalis scouleri= Hooker.

Common along streams at low elevations.

=BERBERIDACEAE.= (Barberry Family.)

=Achlys triphylla= (Smith) De Candolle.

Reported by Mr. Gorman "on the trail from Longmire Springs to the Park." The sweet-smelling leaves of this plant have suggested the name of "vanilla leaf."

=RANUNCULACEAE.= (b.u.t.tercup Family.)

=Thalictrum occidentale= Gray.

This meadow-rue is not rare near the foot of Van Trump Glacier.

=Anemone drummondii= Watson.

Collected by Flett, No. 2171, on the north side of the mountain at 7,000 feet alt.i.tude.

=Anemone hudsoniana= (De Candolle) Richardson.

Collected on the Goat Mountains by Mr. Allen, No. 250.

=Pulsatilla occidentalis= (Watson) Freyn.

Common on the dry slopes 5,000 to 6,000 feet elevation. Flowers large, white or bluish, developing a large head of tailed carpels, which has much the appearance of a hussar's cap.

=Trautvetteria grandis= Nuttall.

A tall plant with large maple-like leaves and loose corymbs of delicate white flowers. Abundant in shady woods up to 4,000 feet elevation. The pallid blossoms, in sharp contrast to the shade they dwell in, has prompted the name of "ghost flower."

=Ranunculus suksdorfii= Gray.

A bright-flowered b.u.t.tercup, not rare in moist places at 5,500 feet elevation.

=Ranunculus verecundus= Robinson.

On rocky ridges at 7,000 feet alt.i.tude, Flett.

=Caltha leptosepala= De Candolle.

(_C. macounii_ Greene.)

Wet places, 4,000 to 6,000 feet; plentiful.

=Aquilegia formosa= Fisher.

The common scarlet and yellow columbine of the lowland, found on the gra.s.sy slopes at 5,500 feet elevation.

=Delphinium bicolor= Nuttall.

A handsome blue and white-flowered larkspur, found in the Goat Mountains by Mr. Allen, No. 146.

=Delphinium glauc.u.m= Watson.

This larkspur is tall, three to four feet high, with rather many large leaves, and long racemes of pale blue small flowers. Collected by Mr.

Allen in the Upper Nisqually Valley, and by the writer near Crater Lake.

=CARYOPHYLLACEAE.= (Pink Family.)

=Silene lyallii= Watson.

A prostrate chickweed, common along the Paradise River, at 5,000 feet elevation.
