    Stems erect, branched from bases or throughout.
    Leaves basal and cauline;
    proximal opposite (sometimes rosettes), distal alternate;
    blades oblong to linear, lance-linear, or oblanceolate, margins entire or toothed, faces hirsute to strigose or pubescent and (distal leaves) stipitate-glandular.
    Heads radiate or discoid, borne singly or in corymbiform or racemiform arrays.
    Peduncular bracts: pit-glands, tack-glands, and/or spines 0 at tips.
    Involucres ± globose or broadly ellipsoid to campanulate, 4–6+ mm diam.
    Phyllaries 0 (see paleae at receptacles) or falling, 1–3 or 7–15 in 1 series (lanceolate to lance-attenuate or oblanceolate, herbaceous, each 1/2 or fully enveloping subtended ray-floret proximally, ciliolate, abaxially stipitate-glandular, sometimes hirtellous).
    Receptacles flat to convex, glabrous or setulose, paleate (paleae falling, in 1 series, between rays and discs, usually connate, sometimes distinct, phyllary-like, more scarious; in discoid heads, functionally an “involucre”).
    Ray-florets 0, 1–3, or 8–15, pistillate, fertile;
    Disc-florets 5–30, bisexual and fertile, or functionally staminate;
    corollas yellow, tubes shorter than funnelform throats, lobes 5, deltate (styles glabrous proximal to branches; anthers yellow).
    Ray cypselae (black or grayish) compressed or ± obcompressed, clavate, ± arcuate (basal attachments centered, apices beaked, beaks offset adaxially, 0.2–0.3 mm, faces glabrous or hairy);
    pappi 0 or coroniform.
    Disc cypselae (black or grayish) ± terete, clavate (± straight, faces hairy);
    pappi of 5–8 or 11–21 lanceolate, linear, quadrate, or subulate, ciliolate-plumose, erose, or fimbrillate scales.
