Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Spring ephemeral with milky sap, glabrous or slightly puberulent herbage, scapes 10-60 cm tall. Leaves: Linear to linear-lanceolate or pinnate with few slender segments, in basal rosette, 10-15 cm long, stems above leafless with small glands near flower head. Flowers: Each stem bearing single, erect head; outer involucral bracts 1 cm long, acute, ligules barely surpassing involucre, ephemeral, pale yellow but drying reddish or purplish. Fruits: Cypselae 8.5-10 mm long, blackish, linear-cylindric and slightly tapered at each end, apex slightly flared; pappus with 5 papery, silvery, linear-lanceolate scales 9-10 mm, these deeply notched at the apex with long, slender awn from notch. Ecology: Found on mesas, plains, outwash slopes and arroyos below 5,000 ft (1524 m); flowers March-June. Distribution: Most of western N. Amer., from B.C. south to CA and west to TX, UT, ID; south to n MEX. Notes: Distinct by being scapose with all basal,divided leaves, milky sap and especially the shiny silver pappus awns. Ethnobotany: Unknown Etymology: Uropappus refers to the pappus having a long tail-like dip, while lindleyi is named for John Lindley (1799-1865) a British botanist.
