LEAVES: Most of the oblong leaves grow at or just above ground level; those higher on the flowering stalks are smaller. Margins of leaves are broadly toothed. Several varieties or subspecies are recognized based on variation in the size, shape and texture of the leaves. The specimen shown here had thick, soft pubescence on the underside.

FLOWERS: Bright yellow rays and disc florets formed into a daisy-like inflorescence.

PERENNIAL: When in bloom the flower stalks reach a height of 1 meter tall.

RANGE: Grows in the partial shade with deeper soils along the terraces adjacent to sycamore-lined streams. At higher elevations this plant can also be found in drier, open habitats such as oak-juniper woodlands and ponderosa woods. Ranges from Utah to Texas and south into Mexico.

FRUIT: The seeds are topped with long, fine bristles.
