| Perennials, 15–60 cm; rhizomatous, fibrous-rooted, primary rhizomes relatively slender, producing slender, herbaceous, scale-leaved, stoloniform rhizomes (rhizomes often not collected). |
Perennials, 7–75 cm; taprooted (taproots usually not collected, often weakly developed), roots and caudices woody, branches rhizomelike (3–15 cm; fibrous-rooted), relatively slender, leafless, ascending. |
erect to ascending (usually abruptly dilated proximal to heads), villous (more densely so on proximal 1/2), eglandular. |
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. |
basal (persistent) and cauline; basal blades oblanceolate to obovate or suborbiculate, subspatulate, 20–130(–180) × 6–30(–50) mm; cauline gradually reduced distally (bases clasping and slightly auriculate), margins usually dentate to denticulate, rarely entire, faces sparsely to moderately hirsute to hirsuto-villous, sometimes glabrate or glabrous (especially adaxially), 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. |
5–7 × 6–20 mm. |
mostly 4–6 × 9–14 mm. |
50–80(–100); corollas light blue to purplish, pink, or white, 6–10 mm, laminae coiling tardily at tips. |
20–62; corollas white or pink, often drying blue, 4–7 mm, laminae weakly coiling. |
4.5–6 mm. |
3.5–5.5 mm (throats slightly indurate, not inflated). |
in 2–3(–4) series, sparsely to moderately hirsute to hirsuto-villous (cross walls not distinctly colored), minutely glandular to stipitate-glandular. |
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. |
1–4(–9). |
1 or 2–5(–10) in loosely corymbiform arrays. |
1.3–1.8 mm, 2(–4)-nerved, faces sparsely strigose to glabrate or glabrous; pappi: outer 0 or of setae, inner of (22–)28–36 bristles. |
2–3 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of (15–)20–35(–50) bristles. |
