Glandular paintbrush as seen on Lookout Rock, Monument Rock Wilderness..........August 2, 2011.
Glandular paintbrush is a perennial wildflower with clustered, erect or ascending
stems arising 10-40 cm from a woody base. The angled stems may be simple or
branched, and are strongly glandular-hairy. The lower leaves are linear-lanceolate
in shape with entire margins while the upper leaves are wider with a pair of
short lateral lobes.
The bracts and calyces are pale to deep yellow, or occasionally a dull orange-red
color. The sticky bracts have 1-2 pairs of lateral lobes and are usually shorter
than the flowers. The calyx is 15-20 mm long, roughly equally parted above and
below, the lateral segments again parted 2-6 mm into lanceolate segments. The
corolla is 20-25 mm long, the hairy galea about 2/3 as long as the tube and
about 5 times longer than the dark green, thickened, and incurved lower lip.
Glandular paintbrush is limited to dry, rocky or gravelly slopes
at moderate to high elevations in the mountains.
Glandular paintbrush is found in the Blue and Wallowa Mts. of
