Duration: Annual Nativity: Native Lifeform: Forb/Herb General: Herbaceous winter annuals, prostrate, diffusely branched, herbage covered with stiff, white hairs. Leaves: Leaves (phyllaries), alternate, thickish, often tufted below heads, linear to spatulate, obtuse to subacute, entire, 5-10 mm long, covered with stiff, white hairs. The upper leaves subtend the heads. Flowers: Heads somewhat showy, radiate, rays white to purple, often dark-veined, many, corollas 6-11.5 mm long, ligules 5-8.5 mm long, disk flowers yellow, many, receptacles convex, naked, involucres broad, bell-shaped or hemispheric, phyllaries 4-6 mm, many in 1 series, equal, folded, with acuminate tips, purplish, solitary heads borne subsessile or on short stems to 25 cm. Fruits: Achenes 2-nerved, compressed, oblong to obovate, finely appressed-hairy, light brown, 1.5-2 mm long. Pappus of 0-12 , 1-2 mm long, with several slender scales, 0.5-1 mm long, these dissected into bristles. Ecology: Found on sandy or gravelly soild on flats, dunes, deserts and washes, from 200-3,500 ft (61-1067 m); flowering February-May. Distribution: Arizona, California, Nevada, Utah; Mexico. Notes: Monoptilon spp. are easy to recognize by their compact, often decumbent growth form; relatively large daisy flowers with white rays and yellow centers; and somewhat thick leaves covered with stiff, white hairs. Differentiate from M. bellidforme by the pappus attached to the top of the seed; M. bellioides has a pappus of several bristles of unequal lengths, plus sometimes a few scales; M. bellidiforme has pappus consisting of a scarious cup plus single plumose bristle. Ethnobotany: Unknown. Etymology: Monoptilon comes from the Greek monos for one and ptilon for feather, referring to the single plumose bristle attached to the seed of sister species M. bellidiforme; bellioides means resembling the genus Bellis.
