Flora of North America species comparison

usually ascending, sometimes prostrate to procumbent or decumbent (var. jacinteus) (often purple, distal branches stiff, spreading-ascending), hispid (hairs spreading-deflexed, 0.1–0.4 mm), mostly eglandular.

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

cauline; (ascending) blades narrowly oblong-lanceolate to narrowly obovate, 10–40 × 2–5 mm, margins entire, relatively evenly spaced and sized, hispid, mostly 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.

mostly 4–6 × 9–14 mm.

3–5 × 6–12 mm.

20–62;

corollas white or pink, often drying blue, 4–7 mm, laminae weakly coiling.

80–125;

corollas white, 4–10 mm, laminae tardily coiling.

3.5–5.5 mm (throats slightly indurate, not inflated).

2–2.8 mm.

in 3–5 series (all but outermost with stramineous margins and distal, greenish-herbaceous, narrowly rhomboid areas), strigoso- to hispido-hirsute or essentially glabrous, densely minutely glandular.

in 2–3(–4) series, sparsely villous or hirsuto-villous, minutely glandular.

1 or 2–5(–10) in loosely corymbiform arrays.

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

2–3 mm, 2-nerved, faces sparsely strigose;

pappi: outer of setae, inner of (15–)20–35(–50) bristles.

0.8–1 mm, 2-nerved, faces sparsely strigose;

pappi: outer minute crowns of setae or narrow scales, inner 0 (rays) or of 8–11 bristles (disc).
