| Perennials, (15–)25–55 cm (not colonial); taprooted, taproots thin (2–3 mm wide), caudices simple or with relatively slender and short, erect branches. |
Perennials, 4–18 cm; taprooted, caudex branches relatively short, thick. |
(often purplish) erect or decumbent, sparsely strigillose (basal cells inclined, hairs even-width), eglandular. |
erect (greenish), usually closely appressed-strigose, sometimes glabrate, eglandular. |
basal (often withering by flowering) and cauline; basal blades (3-nerved) linear to narrowly oblanceolate, 90–170 × 3–7 mm; cauline gradually reduced distally, ending proximal to heads, margins entire, faces strigoso-hirsute, eglandular. |
mostly basal or basal (persistent, persistent portion relatively long and slender-fibrous) and cauline (greenish); basal blades 1-nerved linear to linear-oblanceolate or oblanceolate or narrowly spatulate, (20–)30–80 × (0.5–)1–3 mm; cauline reduced distally (bases attenuate, not thickened and whitish-indurate) margins entire (apices obtuse or rounded), faces abaxially glabrous or glabrate, adaxially sparsely strigose, eglandular. |

in 2–3(–4) series (narrowly oblanceolate to lanceolate, acute-acuminate), sparsely to moderately hirsute to villous, eglandular. |
in 2–4 series (greenish or sometimes purple, margins thickened), strigose to loosely strigoso-hirsute, sometimes more densely so on distal 1/3, sparsely minutely glandular. |
1–3. |
1(–3 rarely, from branches at midstem). |
(1.8–)2–3.2 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 15–22 bristles. |
