| Perennials, 5–55(–70) cm; rhizomatous, fibrous-rooted, caudices usually simple, thick. |
Perennials, 3–10(–12) cm; rhizomatous, fibrous-rooted, rhizomes or caudices simple, relatively short and thick. |
erect to basally ascending, hirsute to hirsuto- or strigoso-villous (hairs loosely appressed, slightly crinkled), sometimes loosely strigose distally (var. thompsonii), eglandular. |
erect, densely cobwebby-lanate (hairs white), eglandular. |
basal (persistent) and cauline; basal blades linear-oblanceolate to broadly lanceolate or spatulate, (30–)50–100 × 5–25 mm; cauline gradually reduced distally (bases distinctly subclasping, except when greatly reduced), margins entire, faces hirsute, hirsuto-villous, sparsely villosulous, glabrate, or glabrous, eglandular. |
basal (persistent) and cauline; blades oblanceolate to subspatulate, (10–)20–60 × 2–10 mm, margins entire, faces lanate, eglandular; cauline blades oblong to linear-oblong, gradually reduced, bractlike. |
5–9(–12) × 10–22(–25) mm. |
8–10 × 12–20 mm. |
30–80; corollas usually blue to rose purple or pink, sometimes white to pale blue, 12–20(–25) mm (mostly 1.5–3 mm wide), laminae coiling. |
60–100; corollas white, often drying pinkish, 8–13 mm (mostly 1–2 mm wide), laminae coiling. |
3.5–4.5 mm. |
3.5–5 mm. |
in 2–3(–4) series (margins usually ciliate), abaxially sparsely to moderately villoso-hirsute, usually eglandular, sometimes sparsely gland-dotted apically, rarely sparsely so over adaxial faces (especially in var. thompsonii). |
in 2(–3) series (purple beneath pubescence), densely and closely lanate, sparsely glandular (glandularity obscured). |
