Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Herbaceous perennials to 60 cm tall, herbage copiously to densely hirsute, at least below, stems leafy. Leaves: Alternate, oblong, somewhat broad with a clasping base, margins roughly denticulate, at least remotely, copiously to densely hirsute. Flowers: Heads small, the corollas yellow, involucres 8-12 mm, phyllaries equal, acuminate, stipitate-glandular, involucres and peduncles copiously to densely long hirsute, inflorescences borne singly or few in corymbiform to paniculiform arrays. Fruits: Achenes columnar, not tapering, ribbed. Pappus of brownish or white capillary bristles. Ecology: Found in moist areas in Ponderosa pine forests, from 7,000-8,000 ft (2134-2438 m); flowering July-October. Distribution: Arizona, New Mexico. Notes: Look for this species under Hieracium Lemmoni in older texts. Good identifiers for this species are the densely long-hirsute stems, the denticulate leaves (at least remotely), and the glabrous to stipitate glandular involucres 8-12 mm high. Ethnobotany: There is no specific use recorded for this species, but the genus was used to treat mouth sores, consumption, and chewed for pleasure. Etymology: Hieracium comes from the Greek hierax, a hawk, while crepidispermum comes from the Greek krepis a sandal and spermum for seed, or seed like the genus Crepis. Synonyms: Hieracium lemmonii Editor: LCrumbacher 2011
