ROSACEAE. (Rose Family.)
Spiraea densiflora Nuttall.
A low shrub with dense corymbs of rose-colored flowers. Common in bogs at 4,500 feet, and on rock cliffs up to 6,000 feet elevation.
Eriogynia pectinata (Pursh) Hooker.
A little shrub only two or three inches tall, forming dense mats. The plant should easily be recognized by its sharply cleft leaves and dense erect racemes of white flowers. Abundant at 5,000 to 6,000 feet elevation. Gorman reports it from near the "Sphinx," 8,500 feet.
Rubus nivalis Douglas.
A trailing vine, with glossy, green, simple leaves. Common in the coniferous forests at 3,000 feet altitude, where it seldom blooms. On exposed rocks and banks one rarely finds its dull red flowers or bright red, raspberry-like, sour fruit.
Rubus pedatus Smith.
A trailing herbaceous plant, with palmately compound leaves and strawberry-like blossoms. The smooth red fruit is sour, and consists of only a few large drupelets. Common in the woods up to 4,000 feet altitude.
Rubus lasiococcus Gray.
Much like the preceding, but with simple leaves and pubescent fruit. Grows with the preceding, and up to 5,000 feet or more.
Potentilla flabellifolia Hooker.
The common cinquefoil of the meadows, with bright yellow buttercup-like flowers. Plentiful at 5,000 feet elevation.
Potentilla dissecta Pursh.
This has been collected by Allen on the Goat Mountains, No. 251.
