    petiolate or sessile;
    blades (1–7-nerved) mostly cuneate, elliptic, lanceolate, linear, oblanceolate, or spatulate, margins entire, abaxial faces usually tomentose, adaxial glabrous or ± tomentose to sericeous or glabrescent.
    Heads discoid (unisexual), borne singly or in corymbiform, paniculiform, racemiform, or subcapitate arrays.
    Involucres: staminate campanulate to hemispheric, 2–6+ mm diam.;
    pistillate turbinate or campanulate to cylindric, 3–7 (–9+) mm diam.
    Phyllaries in 3–6+ series, usually relatively narrow, unequal (proximally papery or membranous; distally ± scarious, often black, brown, castaneous, cream, gray, green, olivaceous, pink, red, white, or yellow), apices usually acute, sometimes obtuse to ± truncate.
    Receptacles flat to convex or ovoid, foveolate, epaleate.
    Disc-florets mostly 20–100+, (functionally) staminate or pistillate;
    staminate corollas white, yellow, or red, narrowly funnelform or tubular (lobes usually 5, erect to recurved);
    pistillate corollas white, yellow, or red, narrowly tubular to filiform.
    Cypselae mostly ellipsoid to ovoid, faces usually glabrous, often papillate (stout, myxogenic twin-hairs);
    pappi: falling (bristles basally connate or coherent, shed together in rings or in groups);
