Characteristics:
Pale Wallowa paintbrush is an attractive perennial wildflower with clusters
of unbranched stems rising 10-30 cm high. The herbage is densely covered with
fine, curled or crinkled hairs. The leaves are ascending, 2-3.5 cm long the
lower linear with entire margins, the upper leaves with 1-2 pairs of thin, spreading
lobes.
The dull yellowish or purplish bracts are much shorter and wider than the leaves
with 1-2 pairs of lateral lobes. The calyx is 10-12 mm long, cleft medially
about equally on the upper and lower surfaces. The lateral calyx segments are
again divided into 2 linear segments from 2-5 mm long. The corolla is 15-16
mm long, the galea narrow and less than half as long as the tube. The prominent,
pouched lower lip is 2/3 to as long as the galea.
Habitat:
Pale Wallowa paintbrush is often found with sagebrush on dry hillsides and
in the plains.
Range:
Pale Wallowa paintbrush may be found in the Blue and Wallowa Mts. of northeastern
Oregon and in the mountains of western Idaho.
