Characteristics:

Piper's anemone is an attractive perennial wildflower with glabrous herbage and usually one (occasionally several) stems arising from 15-35 cm high, topped by single flowers. If present, the single basal leaf is trifoliolate with coarsely double-toothed margins. The lateral pair of leaflets may be bilobed over half their length. The 3 involucral leaves are each trifoliolate heavily strigillose with similar shape to the basal leaves. The involucral leaves are larger however, the leaflet blades measuring up to 7 cm long.

The 5-7 whitish sepals are oval in shape and 12-16 mm long, often with pinkish to purplish outer surfaces. The stamens usually number from 35-55. The style is straight, glabrous, and measures from 1.5-2 mm long.

The species is named in honor of Professor C.V. Piper from type specimens he collected in 1893 in Latah County, Idaho.


Habitat:

Piper's anemone is found in shady, moist coniferous forests in the mountains.


Range:

Piper's anemone is found from the Blue Mts. of northeastern Oregon and southwestern Washington east through central Idaho to Mineral County in Montana.
