Flora of North America species comparison

erect, stramineous to red-brown, villous and/or stipitate-glandular (at least distally).

erect, stramineous to purple, proximally sparsely hirtellous to glabrate, distally ± hirtellous to villosulous.

blades lanceolate or lance-attenuate (broadest proximal to midpoints), 35–70(–90) mm, lengths 2–4(–10) times widths, bases usually clasping (± cordate), margins usually entire, rarely serrate to denticulate (teeth apiculate), apices acute to attenuate, faces stipitate-glandular.

blades ovate or ± triangular to oblong or obovate, 15–60(–90) mm, lengths 1.5–3(–4+) times widths, bases ± clasping, margins ± crenate (teeth 8–14 per cm, blunt, resin-tipped), apices obtuse to acute, faces usually hirtellous to scabridulous and glandular (glands usually in pits, sometimes sessile, seldom stipitate), sometimes glabrate.

broadly urceolate to globose, 8–12 × 12–20+ mm (usually subtended by leaflike bracts).

± urceolate to hemispheric, 8–12 × 10–20 mm (usually subtended by leaflike bracts).

10–35;

laminae 8–15(–20) mm.

20–27;

laminae 8–12 mm.

in 5–6 series, spreading to appressed, linear or to lance-linear or lanceolate, apices slightly recurved, straight, or incurved, filiform to subulate, ± stipitate-glandular, sometimes moderately resinous as well.

in 4–6 series, spreading to appressed, lanceolate to linear, apices subulate, hooked to ± recurved or nearly straight, moderately resinous.

in corymbiform arrays or borne singly.

in open, corymbiform to paniculiform arrays or borne singly.

stramineous, 3–5 mm, apices coronate to knobby, faces smooth or striate;

pappi of 2–3 contorted to curled, usually smooth, sometimes barbellulate, subulate scales 2.5–4 mm, shorter than disc corollas.

stramineous or brownish, 3–4.5 mm, apices ± coronate to knobby, faces (outer) rugose (not transversely fissured; angles ± ribbed) or (inner) striate;

pappi of 2 straight or weakly contorted, smooth (apices dilated), bristles or setiform awns 5–6 mm, equaling or surpassing disc corollas.
