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.
