As its name implies, pungent desert parsley has a definite pungent,
sometimes malodorous smell when its herbage is lightly crushed. It is a perennial
wildflower with several glabrous stems ascending from 15-50 cm high from a thick
taproot topped by the remains of previous years' leaves. The herbage ranges
from glabrous and glaucous to slightly rough to the touch. The leaves are 6-10
cm long with inflated petioles. They are largely basal and are ternate-pinnately
compound, being dissected into numerous narrow linear acute segments up to 6
mm long and the segments oriented in many planes.
The inflorescence is an umbel, the unequal stems beneath each
umbelet measuring from 3.5-10 cm long. The petals are yellow. The fruit are
elliptic in shape, the lateral wings from 1/3-2/3 as wide as the body, and measuring
8-15 mm long.
Pungent desert parsley may be found in dry, open and rocky places
from the lowlands to moderate elevations in the mountains.
Pungent desert parsley may be found from central Washington
south to the east of the Cascade Mts. to central Oregon and east to northern
Idaho, northeastern Nevada, southwestern Wyoming, Utah, and southwestern Colorado.
In the Columbia River Gorge, it may be found between the elevations
of 100'-2500' from near Crown Point eastward throughout most of the eastern

The photo at right shows pungent desert parsley blooming on rocky slopes above the Crawford Oaks Trailhead, Columbia Hills State Park.........February 23, 2016. Both of these plants are very early plants, so they haven't had a chance to assume the broad, lacy and globose form the plants display later in season.
