Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Perennial herbs, 15-40 cm tall, from stout woody rootstock; stems strigose-hirsute. Leaves: Leaves alternate along the stems, the blades pinnatifid to bipinnatifid with 2-7 linear to lance-ovate lobes, the surfaces hirsute-strigose. Flowers: Flower heads radiate, the receptacles conspicuously plump but the rays inconspicuous; heads set above the leaves on peduncles 2-7 cm long; involucres 4-10 cm diameter, the bracts (phyllaries) linear-lanceolate, spreading to reflexed, in 2 series, the outer series 2-5 mm long, the inner series shorter; ray florets 5-10 per flower head, the laminae (ray petals) elliptic-oblanceolate, 3-10 mm long and 2-6 mm wide, yellow to reddish or purplish brown, often bicolored; receptacle ovoid to ellipsoid, 5-15 mm high and about as wide; disc florets 50-150, covering the round receptacle, the corollas greenish, often with purple lobes; palea subtending each disc floret purple-pubescent, making the disc florets appear purplish gray before they open. Fruits: Achenes oblong, 2-3 mm long, winged, the upper margins and apices sometimes ciliate; topped with a pappus consisting of a low crown of united scales. Ecology: Found in pinyon-juniper and ponderosa pine woodlands, grasslands, gravelly slopes, and and roadsides, from 5,000-7,000 ft (1524-2134 m); flowers June- September. Distribution: KS and CO to TX, NM, and n AZ; south to n MEX Notes: R. tagetes is like a plain litter sister to its showy congener, R. columnifera. It is shorter, usually less than 40 cm tall; it has similar pinnatifid leaves but the lobes are smaller and narrower; and the flower heads, which are on shorter peduncles, have spherical rather than columnar receptacles and smaller ray petals, less than 1 cm long (compared to 1-3 cm ray petals in R. columnifera). Look for it in disturbed sites. Ethnobotany: An infusion of the plant used to treat stomachaches, coughs, and fevers; also used ceremonially. Etymology: The derivation of the genus name Ratibida is unknown; tagetes refers to the marigold genus. Synonyms: Rudbeckia tagetes Editor: AHazelton 2017
