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.
