    Stems usually erect, sometimes prostrate, decumbent, or ascending, usually green to stramineous, brown, or reddish, sometimes whitish, arachnose, hirsutulous, puberulous, or villous (sometimes stipitate-glandular as well), or glabrous (then often resinous).
    Cauline leaf-blades usually oblong, oblanceolate, or spatulate (broadest at or beyond their midpoints), sometimes ovate, lanceolate, or linear, (5–) 10–80 (–120+) mm, lengths 2–8+ times widths, bases clasping or cuneate, margins usually serrate to dentate (teeth apiculate to setose), sometimes entire, apices truncate, rounded, or obtuse to acute, faces hirsutulous, puberulous, or villous and little, if at all, gland-dotted, or glabrous (or scabridulous near margins) and sparsely to densely gland-dotted.
    Heads usually in open to crowded, corymbiform to paniculiform arrays, seldom borne singly.
    Involucres usually broadly urceolate to globose, sometimes hemispheric, campanulate, or obconic, (6–) 8–15 (–20) × (6–) 10–25+ mm (sometimes subtended by leaflike bracts).
    Phyllaries in 4–8+ series, reflexed to spreading or appressed, filiform or linear to ± lance-attenuate, lanceolate, or lance-oblong, apices usually recurved or straight, sometimes (the outer) looped to hooked or patent, terete or filiform to subulate, or acute, usually all glabrous and moderately to strongly resinous, sometimes all or outer villosulous to hirsutulous and little, if at all, resinous, seldom, if ever, stipitate-glandular.

    laminae (4–) 10–25+ mm.
    Cypselae whitish or stramineous to brownish or grayish, (2–) 4–6 (–7) mm, apices usually ± knobby, sometimes coronate, rarely smooth, faces usually smooth, striate, or furrowed, rarely rugose;
