    Leaves mostly cauline (at flowering) proximal opposite (often in rosettes), distal alternate;
    blades lanceolate or oblong-linear to linear, margins usually entire, sometimes toothed, faces hirsute to strigose, usually glandular-pubescent as well.
    Heads usually radiate (sometimes discoid in M. glomerata), in corymbiform, paniculiform, racemiform, or spiciform arrays or in glomerules.
    Peduncular bracts: pit-glands, tack-glands, and/or spines 0.
    Involucres ellipsoid, depressed-globose, globose, obconic, ovoid, or urceolate, 1–10+ mm diam.
    Phyllaries 0 (then outer paleae functioning as phyllaries, sometimes in M. glomerata), or 1–22 in 1 series (lance-linear to lance-attenuate or oblanceolate, herbaceous, each mostly or wholly enveloping a subtended ray ovary, abaxially hirsute and, usually, glandular).
    Receptacles flat to convex, glabrous or setulose, paleate (paleae persistent or falling readily, in 1 series between rays and discs, ± connate or distinct, phyllary-like, more scarious).
    Ray-florets 0 (sometimes in M. glomerata), or 1–22, pistillate, fertile;
    corollas yellowish (with maroon bases sometimes in M. elegans; purplish red sometimes in M. sativa).
    Disc-florets 1–80+, bisexual and fertile or functionally staminate;
    corollas usually yellow, sometimes purplish, tubes shorter than or about equaling funnelform throats, lobes 5, deltate (anthers ± dark purple or yellow to brownish; styles glabrous proximal to branches).
    Ray cypselae compressed, ± 3-angled, or rarely terete, clavate (often arcuate, basal attachments central or offset, apices sometimes beaked, faces glabrous);
    Disc cypselae similar, sometimes obovoid (often ± straight, basal attachments central, apices not beaked), sometimes 0;
