Flora of North America species comparison

erect to ascending, hirsute or hirsuto-villous to densely strigillose (hairs loosely appressed, slightly crinkled), eglandular.

erect, sparsely piloso-hispid (hairs spreading), sometimes strigose distally, eglandular.

basal (usually persistent) and cauline;

basal blades linear-oblanceolate to broadly lanceolate or spatulate, (20–)30–160(–200) × 7–45 mm;

cauline gradually reduced distally (bases distinctly subclasping, except when greatly reduced), margins entire, faces glabrous or glabrate, hirsute, or villous to sparsely villosulous, eglandular.

basal (usually withering by flowering) and cauline;

basal blades mostly lanceolate to oblanceolate or ovate, 15–80 × 3–20 mm, margins coarsely serrate to nearly entire, faces sparsely strigoso-hirsute, eglandular;

cauline lanceolate to oblong, little reduced proximal to midstem.

6–9(–12) × 10–22(–25) mm.

3–5 × 6–12 mm.

30–80;

1(–8).

ca. 5–50+ in loosely paniculiform or corymbiform arrays.

2.5–2.8 mm, (4–)5(–7)-nerved, faces sparsely strigose;

pappi: outer of setae, inner of 20–30 bristles.
