Characteristics:

Dwarf Mountain Fleabane is an attractive, low growing mat plant, with many erect stems from 3-15 cm high capped with a single flower head. The herbage consists of numerous spreading hairs on the stems and leaves. The leaves are narrowly oblanceolate and mostly basal.

The flower heads are yellow, and may be with or without ray flowers. If rayless, as in variety austiniae, 20-60 female flowers are present as disk flowers. The involucre is 4-7.5 mm high and covered with spreading hairs, some of which may be glandular. The disk itself ranges from 9-17 mm wide.

This species flowers from May into July.


Habitat:

Dwarf mountain fleabane may be found in dry, open places, often with sagebrush. It may be found at elevations ranging from 800-2600 meters.


Range:

Dwarf mountain fleabane may be found from eastern Washington south through central Oregon to northern California, and east to Twin Falls, Idaho as well as northeastern Nevada.
