Fruits: Achenes slender, angled or flattened, 5-6 mm long. Pappus of 0-5 lanceolate to awl-shaped, awned scales, 2.5-3 mm long, plus 5+ lanceolate to oblong, erose scales, 0.5-1 mm long, these distinct or connate. Ecology: Found on rich, moist soils, in canyons, from 4,000-8,000 ft (1219-2438 m); flowering August-November. Distribution: Arizona; Mexico. Notes: Look to the marigold smelling herbage and large yellow rays to help identify this species. Etymology: Tagetes is named after the Etruscan god Tages, while lemmonii is probably named for John Gil Lemmon (1832-1908) and his wife Sara Plummer Lemmon (1836-1923) who collected plants for Asa Gray all across the west.
