    Stems erect, simple or basally branched.
    ± petiolate (basal) or sessile (usually appressed to ascending);
    blades usually 1-nerved, sometimes 3-nerved or 5-nerved, mostly linear to ovatelanceolate, margins entire, faces often glanddotted (stipitate-glandular in L. glandulosa).
    Heads discoid, in corymbiform, cymiform, racemiform, or spiciform arrays.
    Involucres mostly campanulate to hemispheric or turbinate-cylindric, (2.5–) 3–22 (–25) mm diam.
    Phyllaries persistent or tardily falling, 18–40 in (2–) 3–7 series, not notably nerved, ovate to elliptic or lanceolate, usually unequal (herbaceous to petaloid, margins often hyaline, often ciliate or irregularly toothed, apices often pink-white).
    Receptacles flat, epaleate.
    corollas usually lavender to dark magenta or pinkish purple, sometimes white, throats funnelform (lengths 4–6 times diams., externally glanduliferous, glabrous inside or pilose inside near filament insertions, hairs whitish, crisped);
    styles: bases not enlarged, glabrous, branches linear-clavate (papillate).
    Cypselae prismatic, 8–11-ribbed, usually hirsutulous to hirtellous-pilose (glabrous in L. oligocephala), usually glanddotted;
    pappi persistent, of 12–40 coarsely barbellate to plumose bristles in 1–2 series.
