Flora of North America species comparison

1–25 (–50+), erect, proximally glabrous or sparsely to moderately canescent-villous, distally densely so.

1–30+, simple, sparsely to densely puberulent proximally to densely so in arrays.

basal 0;

proximal cauline sessile, blades narrowly to broadly oblanceolate, 100–150 × 15–23 mm, tapering to bases, margins subentire to coarsely sharply serrate, 3-nerved, sometimes obscurely so, apices acute to acuminate, abaxial faces glabrate to sparsely short villous, adaxial glabrous;

mid to distal cauline sessile, blades lanceolate to narrowly elliptic, (50–)90–120(–150) × (7–) 11–23(–35) mm, largest near mid stem, then somewhat reduced distally in arrays, margins sharply and coarsely to finely serrate or entire, usually becoming less serrate near arrays, faces glabrous or sparsely strigoso-villous, more so along abaxial nerves, distalmost (below arrays) sometimes sparsely to moderately minutely stipitate-glandular.

basal and proximal winged-petiolate-subpetiolate (poorly differentiated), blades to winged petioles;

blades oblanceolate, largest to 8 cm, usually smaller, gradually attenuate, margins entire, slightly undulate, sparsely to moderately soft-puberulent, somewhat viscid (stipitate-glands very small); mostly withering by flowering, new rosettes sometimes present;

cauline petiolate (petioles 0.5–1 mm), blades (linear) elliptic proximally to (narrowly) lanceolate or ovate distally, largest 50–80 × 15–25 mm, reduced distally and becoming more ovate, 15–20 mm in arrays, margins entire or serrulate.

1–4 mm, villoso-hirtellous, sometimes minutely stipitate-glandular;

bracteoles 0–2, linear-lanceolate, sometimes minutely stipitate-glandular.

0.5–5(–2.5) mm, densely short hispid-canescent, sparsely to densely stipitate-glandular, ± viscid;

bracts small, grading into phyllaries.

campanulate, (2–)2.3–3.8(–5) mm.

broadly campanulate, (3.5–)4–5(–5.5) mm.

(7–)10–16(–22);

laminae (0.5–)0.9–1.6(–2.2) × ca. 0.2–0.5 mm.

6–10;

laminae ca. 3–5 × 1–2 mm.

(2–)5–9(–13);

corollas ca. (2–) 2.5–3.8(–5) mm, lobes (0.4–)0.6–1(–1.4) mm.

10–20;

corollas 3–4 mm, lobes ca. 1 mm.

in 3–4 series, deltate-lanceolate, unequal (outer 1/4–1/2 length of inner), margins sparsely villoso-ciliate, sometimes minutely stipitate-glandular apically or basally, apices acute to attenuate, glabrous or sparsely to moderately, minutely stipitate-glandular apically, sometimes over much of faces.

in 2–3 series, unequal, oblong to linear-lanceolate, acute to attenuate, sparsely to moderately strigose, especially distally, sparsely to densely stipitate-glandular, ± viscid.

14–800+, in sometimes secund, broadly thyrsiform or secund pyramidal arrays, usually leafy proximally, branches ascending or sometimes arching-spreading, leaves often minutely stipitate-glandular.

1–140, not secund, in thyrsiform-paniculiform arrays, sometimes compact, nearly as wide as tall, and rounded, sometimes appearing almost rounded corymbiform, proximal branches sometimes much elongate, not secund, spreading to ascending.

(narrowly obconic) 0.6–1.2 mm, strigillose;

pappi 2.5–3.3 mm.

1.5–2.5 mm, ± moderately short-strigose;

pappi 3–4 mm.
