    Stems erect, not branched (± scapiform; stems of “staminate” plants wither soon after flowering, stems of “pistillate” plants elongate after flowering).
    petiolate or sessile;
    basal (usually appearing after heads) palmately or palmati-pinnately nerved, mostly deltate to ovate or orbiculate, margins entire, denticulate, or toothed to lobed, abaxial faces ± tomentose, adaxial tomentulose and glabrescent or glabrous;
    cauline (sessile) bractlike (essentially expanded petioles, proximal sometimes bearing blades).
    Heads radiate, discoid, or disciform, usually in corymbiform, paniculiform, or racemiform arrays, rarely borne singly {“staminate” heads usually radiate, peripheral 1–20 (–70) florets styliferous and sterile or neuter, inner 11–78 florets usually functionally staminate, rarely bisexual and fertile; “pistillate” heads usually radiate, peripheral (1–) 30–130+ florets pistillate and fertile, inner 1–12 florets functionally staminate}.
    Calyculi 0 or of 1–5+ bractlets.
    (expanding in fruit).
    Phyllaries persistent, mostly 12–15 in (1–) 2 series (often purplish-tinged), erect, distinct or connate, narrowly oblong to linear (1–5-nerved), subequal, margins ± scarious (apices not black).
    Receptacles flat to convex, foveolate, epaleate.
    Ray-florets 0 or (1–) 30–130+, usually fertile (in pistillate heads), sometimes styliferous and sterile or neuter (in staminate heads);
    corollas whitish or pinkish to purplish [yellow] (tubes filiform, laminae linear to oblong; styles filiform to clavate, entire or shallowly 2-cleft, papillate).
    Peripheral (pistillate) florets usually 30–125 and fertile, sometimes 0;
    corollas whitish or pinkish to purplish [yellow] (filiform, usually 5-lobed, sometimes minutely bilabiate; styles filiform to clavate, entire or shallowly 2-cleft, papillate).
    Inner (functionally staminate or bisexual) florets 1–78, usually functionally staminate, rarely bisexual and fertile;
    corollas whitish [yellow] (tubes longer than ± campanulate throats, lobes 5, erect or recurved, lanceolate to linear; styles linear to clavate, branches usually 0 or short-conic and papillate, sometimes lanceolate to oblong and ± hispidulous).
    Cypselae narrowly cylindric to weakly fusiform or ± prismatic, 5-ribbed or 10-ribbed, faces glabrous [villous];
    pappi (pistillate florets) readily falling or fragile, of 60–100+, white, smooth or barbellulate bristles (elongating in fruit).
