Characteristics:
Bare-stem desert parsley is a fairly easy to identify
desert parsley (at least in the Pacific Northwest) due to the erect, solitary
to several hollow stems which inflate or increase greatly in diameter directly
beneath the inflorescence. The naked stems range from 20-90 cm high and are
generally both glabrous and blue-glaucous. The firm leaves are found only near
the base and are ternately or ternate-pinnately 1-3 times compound with 3-30
veiny, often petiolate lanceolate to ovate leaflets from 2-9 cm long and 1-6
cm wide. The leaflet margins may be entire or may be toothed at the tips.
The inflorescence is an umbel of numerous small
umbelets which are usually widely spaced when in flower. The stems which hold
the umbelets in the umbel extend unequally from 6-20 cm. The flowers are yellow.
The fruit is 7-15 mm long, oblong to elliptic in shape, narrowing to a short
beaklike tip. The wings of the fruit are up to one-half as wide as the body.
Habitat:
Bare-stem desert parsley maybe found from the lowlands
to moderate elevations in the mountains on dry, open or sparsely wooded places,
and is often mixed with sagebrush or ponderosa pine.
Range:
Bare-stem desert parsley may be found from southern
British Columbia south along both sides of the Cascade Mts. through Washington
and Oregon to central California and east to southwestern Alberta, western and
southern Idaho, and western Utah.
