Flora of North America species comparison

1–5+, sparsely to moderately short strigose or villous.

1–5, densely, evenly villoso-tomentose (hairs white, thin, crisped).

basal withering by flowering, petiolate, smaller to much smaller than cauline, blades oblanceolate, margins serrate;

cauline sessile, blades elliptic-lanceolate or -oblanceolate, mid 80–140 × 2.5–4 mm, distally reduced, usually membranous, bases tapering, attenuate, margins sharply toothed along much of length to nearly entire, ciliate, abaxial faces short-pilose along small and large nerves, adaxial short-pilose along larger nerves.

basal 0;

mid and distal cauline lanceolate to narrowly lanceolate, 3-nerved, 50–80(–120) × 5–10(–12) mm, reduced distally to 10–20 mm, margins shallowly crenate or serrate to nearly entire, faces moderately to densely short pilose (hairs somewhat ascending).

1–6 mm, moderately canescent;

bracteoles linear to lanceolate.

moderately to densely villoso-strigillose, rarely sparsely minutely stipitate-glandular;

bracteoles 1–2(–4).

campanulate, 4.5–5.5 mm.

narrowly campanulate, 3–4 mm.

corollas 2.8–3 mm, lobes 0.4–1.1 mm.

in ca. 3 series, strongly unequal, erect to slightly squarrose-tipped, lanceolate, apices acute, glabrate, sparsely to moderately, finely stipitate-glandular.

in 3–4 series, oblong-lanceolate or lanceolate to narrowly elliptic, strongly unequal, margins apically ciliate, glabrous, rarely outer sparsely, minutely stipitate-glandular.

5–160 (2–10+ more per short branch cluster), in narrowly elongate paniculiform arrays, branches usually 1–6 cm (much longer in damaged plants, sometimes 1–3 proximal branches much elongated in undamaged plants), ascending and bearing short terminal racemiform or paniculiform clusters.

80–950, secund, in narrowly pyramidal paniculiform arrays, 3–4 times as long as wide, branches spreading and slightly secund, bracts linear-lanceolate, 3–6 mm.

(reddish brown) 2–3 mm, glabrous;
