    Stems usually 1, usually erect, branched distally or throughout, glabrous or hairy (sometimes hispid to setose).
    sessile or petiolate;
    blades orbiculate, ovate, oblong, or lanceolate to oblanceolate, linear, or filiform, margins entire or denticulate to pinnately lobed (faces glabrous or hairy, often ± setose).
    Heads borne singly or in corymbiform to paniculiform arrays.
    Peduncles not inflated distally, sometimes bracteate.
    Calyculi of 3–10+, deltate to lanceolate bractlets in 2–3 series (sometimes intergrading with phyllaries).
    Involucres campanulate to cylindric, 2–5 [–8+] mm diam.
    Phyllaries 5–13+ in ± 2 series (erect or reflexed in fruit), lanceolate to linear, usually subequal to equal, margins sometimes scarious, apices obtuse to acute.
    Receptacles flat to convex, pitted, glabrous, epaleate.
    corollas yellow, bluish, or whitish.
    Cypselae reddish-brown, tan, whitish, or purplish to blackish, bodies compressed to flattened, elliptic to oblong, beaks stout (0.1–1 mm, gradually or weakly set off from bodies) or filiform (2–6 mm, sharply set off from bodies), ribs 1–9 on each face, faces often transversely rugulose, usually glabrous;
    pappi persistent (borne on discs at tips of cypselae or beaks), obscurely double (spp. 1–2), each a minute, erose corona 0.05–0.2 mm subtending 40–80+, white or fuscous, ± equal, barbellate to barbellulate bristles in 1–2 series, or simple (spp. 3–10) of 80–120+, white, ± equal, barbellulate to nearly smooth bristles in 2–3+ series.
