Bruce G. Baldwin

Annual 1–10(15) dm. Stem: ± erect. Leaf: mostly cauline, proximal opposite, most alternate, ± sessile; blade narrowly elliptic to linear or proximal oblanceolate to spoon-shaped, entire or proximal sometimes toothed, coarse-, soft-, or silky-hairy or strigose, all or distal sometimes also stalked-glandular. Inflorescence: heads radiate, in tight groups or ± panicle-like clusters; involucre 3–6+ mm diam, ± hemispheric or obovoid to obconic, sometimes subtended by calyx-like set of bracts; phyllaries 5 in 1 series, linear to oblanceolate, each wholly enveloping a subtended ray ovary, spreading and falling with fruit, on angles coarsely long-straight-hairy to minutely coarse-hairy or scabrous; receptacle flat to convex, densely bristly; paleae in ring between ray and disk flowers, fused or free, scarious. Ray flower: 5; corolla yellow, ray fan-shaped, deeply lobed, abaxially often red- to purple-veined. Disk flower: 6, staminate; corolla yellow, tube < throat, lobes deltate; anthers ± dark purple, tips triangular-ovate to ± rounded; style glabrous proximal to undivided, awl-shaped, short-hairy tip. Fruit: ray fruit ± compressed front-to-back, glabrous, black, tip beakless, pappus 0; disk fruit 0, pappus 0.
5 species: California, to Washington, Montana, Nevada. (Greek: hare leaf, for soft-hairy leaves) [Baldwin 2013 Madroño 60:249–254] Easily overlooked; leaves wither early, heads close at mid-day. Lagophylla diabolensis newly described, added as native.
