Characteristics:
Hall's goldenweed is a much branched perennial with a woody
base and annual branches found primarily in the Columbi River Gorge. The stems
and leaves are rough to somewhat smooth throughout with resinous involucral
bracts. The lower leaves are reduced in size and often have begun to drop by
flowering time. The middle and uper leaves are only gradually reduced in size.
Individual leaves are oblanceolate to linear-oblong or oblong-lanceolate in
shape. They range from 2-5 cm long and 3-11 mm wide. The leaves are also firm
to the touch and are generally ascending to erect in their arrangement along
the stems.
The flower heads are densely to loosely arranged at the ends
of the stems. The involucre is 8-11 mm high with shingin, resinous bracts, the
bracts arranged like very narrow shingles in a series of several rows. The bracts
have short green tips. The 5-8 rays are yellow in color and range from 5-8 mm
long. Plants flower from mid August into October.
Habitat:
Hall's goldenweed may be found on dry open to lightly wooded
slopes overlooking the Columbia River.
Range:
Hall's goldenweed may be found between the elevations of 100'-4000'
from near Mount Hamilton eastward to Bigg's Junction, OR. It has also been reported
from the Calapooia Mts. of Oregon.
