| Perennials, 5–55(–70) cm; rhizomatous, fibrous-rooted, caudices usually simple, thick. |
Perennials, 5–60 cm (colonial); taprooted, caudex branches rhizomelike plants. |
erect to ascending, hirsute or hirsuto-villous to densely strigillose (hairs loosely appressed, slightly crinkled), eglandular. |
(often purplish) erect or decumbent at bases, sparsely strigillose (basal cells inclined, hairs even-width), 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 (often withering by flowering) and cauline; basal blades linear to narrowly oblanceolate, 50–120(–180) × 3–6(–11) mm; cauline 3-nerved, gradually reduced distally, margins entire, faces hirtellous, eglandular. |
6–9(–12) × 10–22(–25) mm. |
(4.5–)5–6 × 9–12 mm. |
30–80; corollas usually blue to rose purple or pink, sometimes white to pale blue, 8–16(–25) mm (mostly 1.5–3 mm wide), laminae coiling. |
26–57; corollas white to bluish, sometimes drying pinkish to pale blue, 7–12 mm, laminae not coiling or reflexing. |
3.8–6 mm. |
3–3.5 mm. |
in 2–3(–4) series (faces and margins) usually glabrous, rarely sparsely villous (cross walls not colored), densely and evenly stipitate-glandular. |
in 2–3(–4) series (linear-lanceolate, apices linear-acuminate), sparsely to moderately villous, eglandular. |
1(–8). |
(1–)2–5(–18) borne singly or in loosely corymbiform arrays. |
