erect, stramineous, glabrous (branched distally).

erect, usually reddish, ± villous to hirtellous.

blades oblong to obovate, 30–50(–80) mm, lengths mostly 2–4 times widths, bases ± clasping, margins dentate (teeth apiculate to setose), apices rounded, faces glabrous, obscurely, if at all, gland-dotted.

blades ovoid-oblong or spatulate to oblanceolate or lanceolate, 20–35(–85) mm, lengths 1.5–2.5 times widths, bases ± clasping, margins serrate to denticulate (teeth apiculate to setose), apices obtuse to acute, faces usually puberulous to scabridulous and little, or not at all, gland-dotted, sometimes glabrous.

broadly urceolate, 10–15 × 15–25 mm.

± hemispheric, 7–11 × (10–)15–20 mm (often subtended by leaflike bracts).

laminae 10–15+ mm.

17–30;

laminae (usually more orange than yellow) 12–16 mm.

in 3–5 series, spreading to appressed, subulate to linear-lanceolate, apices recurved to straight, attenuate, slightly to moderately resinous.

in 4–6 series, spreading to appressed, filiform or linear to lanceolate or oblanceolate, apices filiform to subulate, slightly recurved to nearly straight or incurved (usually scabridulous), scarcely to moderately resinous.

borne singly or in open to crowded, corymbiform arrays.

in open, corymbiform arrays or borne singly.

whitish to grayish, 2–4 mm, apices smooth or minutely coronate, faces smooth or striate;

pappi (persistent or tardily falling) of 25–40 barbellate bristles 3–7+ mm subtending 8–15+ barbellate, setiform awns or subulate scales 7–10 mm (the longer surpassing disc corollas).
