    Annuals, biennials, perennials, subshrubs, or shrubs, 3–350 cm (usually, rarely not, aromatic).
    Stems 1–10+, usually erect, usually branched, glabrous or hairy (hairs basi or medifixed).
    petiolate or sessile;
    blades filiform, linear, lanceolate, ovate, elliptic, oblong, oblanceolate, obovate, cuneate, flabellate, or spatulate, usually pinnately and/or palmately lobed, sometimes apically ± 3-lobed or toothed, or entire, faces glabrous or hairy (hairs multicelled and filled with aromatic terpenoids and/or 1-celled and hollow, dolabriform, T-shaped).
    Heads usually discoid, sometimes disciform (subradiate in A. bigelovii), in relatively broad, paniculiform arrays, or in relatively narrow, racemiform or spiciform arrays.
    Involucres campanulate, globose, ovoid, or turbinate, 1.5–8 mm diam.
    Phyllaries persistent, 2–20+ in 4–7 series, distinct, (usually green to whitish green, rarely stramineous) ovate to lanceolate, unequal, margins and apices (usually green or white, rarely dark-brown or black) ± scarious (abaxial faces glabrous or hairy).
    Receptacles flat, convex, or conic (glabrous or hairy), epaleate (except paleate in A. palmeri).
    Ray-florets 0 (peripheral pistillate florets in disciform heads usually 1–20, their corollas filiform; corollas of 1–3 pistillate florets in heads of A. bigelovii sometimes ± 2-lobed, weakly raylike).
    Disc-florets 2–20 (–30+), bisexual and fertile, or functionally staminate;
    corollas (glabrous or ± hirtellous) usually pale-yellow, rarely red, tubes ± cylindric, throats subglobose or funnelform, lobes 5, ± deltate.
    Cypselae (brown) fusiform, ribs 0 (and faces finely striate) or 2–5, faces glabrous or hairy (not villous), often gland-dotted (pericarps sometimes with myxogenic cells, without resin sacs; embryo-sac development monosporic);
