The photo above shows the shallowly bilobed petals of Douglas'
campion as seen on steep prairie slopes above the Imnaha River at the Five Mile Viewpoint along Hat Pt. Road in the Hells Canyon National Recreation Area.......June

Douglas' campion is a tufted perennial with a woody base arising from stout
woody rootstocks. The simple stems are decumbent to erect, measuring 20-40 cm
long. The herbage of the leaves and stems consists of dense, curly and downward
pointing hairs. It is rare that plants are glandular. The leaves are typically
at the base of the stems and on the new stems. The lower leaves have long, tapering
petioles and are narrowly to broadly oblanceolate or linear-lanceolate, measuring
from 2.5-5 cm long and 2-7 mm wide. The 1-8 pairs of stem leaves are linear,
reduced in size, and becoming sessile upwards on the stem.
The inflorescence usually consists of 3-flowered cymes (sometimes 1-7 flowers)
on long pedicels. The cylindrical calyx is 1-1.5 cm long with short, rounded
lobes with broad membranous margins that are often flexed inwards. The calyx
is 10-nerved and becomes inflated in fruit. It is often covered with numerous
fine, short hairs or may be glabrous. It is rarely glandular. The white, greenish-white
to pinkish or purplish petals are exserted from the calyx from 6-9 mm. The blades
of the petals are 2-lobed 1/5-1/3 their length but entire the rest of their
length (occasionally with a small lateral tooth on each margin below the sinus).
Douglas' campion may be found amongst sagebrush in the plains to dry woods
in the foothills and on alpine slopes in the mountains.
Douglas' campion may be found from southern British Columbia
south through the Cascade Mts. to the Sierra Nevada of central California. It
is found eastward through Washington and Oregon to western Montana, northern
Nevada and Utah. It is also found in the Olympic Mts. of Washington.
The photo above shows various views of Douglas' campion as seen on steep prairie slopes above the Imnaha River at the Five Mile Viewpoint along Hat Pt. Road in the Hells Canyon National Recreation Area..........June 26, 2007. Note the lack of any small lateral lobes at the base of each petal, which helps identify this species.
