| Perennials, 2–15(–20) cm; taprooted, caudex branches commonly relatively slender, lignescent. |
Perennials (often short-lived), 10–30 cm; taprooted, caudices woody, simple (stems and leaves arising from near roots). |
erect, sparsely strigillose (hairs white, stiff), sometimes minutely glandular. |
erect (brittle, often subintricately branched), hispidulous (hairs sometimes downcurved or deflexed), eglandular. |
mostly basal (persistent); (gray-green) blades 1-nerved spatulate, rhombic-elliptic to narrowly elliptic-ovate, (10–)15–80 × 2–7 mm, margins entire (apices sharply acute), faces moderately to densely strigillose (hairs white, stiff), eglandular. |
mostly cauline (basal abruptly withering); proximal cauline blades usually linear-oblong, rarely oblanceolate to obovate, 4–10(–20) × 2–6 mm, reduced distally, margins entire, faces hispid, minutely glandular. |
3–5 × 6–12 mm. |
4–5 × 6–8 mm. |
(15–)20–40; corollas blue to purple, 4–8 mm, laminae not coiling or reflexing. |

2.5–4.1 mm. |
3.5–4 mm (throats slightly white-indurate and inflated). |
in 2–3 series, sparsely to moderately hirsute, densely minutely glandular. |
in (2–)3–4 series, glabrous or outer sparsely hispid, minutely glandular. |
1(–3). |
1(–3) per main branch, (–20–30 in later season on wiry, brittle branches). |
1.6–2.5 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 15–25(–30) bristles. |
1.5–1.9 mm, 2-nerved, faces sparsely strigose; pappi: outer of scales, inner of 15–18(–23) bristles. |
