Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Herbaceous perennials to 60 cm tall, stems sparsely hirsute, sometimes also stipitate glandular, herbage often glaucous, plants scapose or if with 1-2 small leaves or bracts, then these not at all clasping. Leaves: Alternate, elliptic or oval to oblanceolate to lanceolate, not at all clasping, copiously to densely hirsute, bases cuneate, margins entire or denticulate, rounded to acute at the tips. Flowers: Heads small, the corollas yellow, the florets 15-30 or more, involucres 8-15 mm, cylindric to campanulate, bractlets 5-8 or more, phyllaries equal, 13-16 or more, apices acuminate, involucres and stems pilose-hirsute and/or stipitate-glandular, inflorescences borne singly or few in corymbiform arrays. Fruits: Achenes columnar, tapering from near the base, ribbed. Pappus of brownish or white capillary bristles in series of 2 or more, 5-8 mm long. Ecology: Found near springs in pine woods and forests, from 6,000-9,500 ft (1829-2896 m); flowering May-August. Distribution: South Dakota to New Mexico, Arizona, and Mexico. Notes: This species resembles a yellow chicory when in bloom. Look to the large heads and tapering achenes to help differentiate from H. crepidispermum. Ethnobotany: A cold infusion of the plant was taken by hunters for anuria, and the leaves were chewed for good luck in hunting Etymology: Hieracium comes from the Greek hierax, a hawk, while fendleri is named for Augustus Fendler (1813-1883). Synonyms: Hieracium fendleri var. discolor, Hieracium arsenia, Crepis ambigua, Chlorocrepis fendleri Editor: LCrumbacher 2011
