| Perennials, 3–8 dm; rhizomatous, fibrous-rooted, caudices relatively thick. |
Perennials, 10–18 cm; taprooted, caudices multicipital or branched. |
erect, loosely strigose to glabrate, sometimes hirsuto-villous proximally, eglandular. |
erect to ascending (branched, brittle), hispido-hirsute (hairs brittle), minutely glandular. |
basal (usually persistent) and cauline; basal and proximal cauline blades often prominently 3-nerved, oblanceolate-spatulate to elliptic-spatulate, 80–200 × 15–35 mm, margins usually coarsely dentate (teeth 1–5 pairs), sometimes entire, faces weakly strigose to hirsute, eglandular; cauline blades becoming lanceolate to linear, sometimes ovate, gradually reduced distally (bases weakly subclasping or not clasping). |
basal (often not persistent) and cauline; blades spatulate 15–30 × 1.5–4 mm, cauline gradually reduced distally (reduced to bracts on peduncles), margins usually 3-lobed (lobes linear to oblong-oblanceolate, about as wide as central portion of blades), sometimes 2-ternate or (cauline) entire, faces sparsely hispido-hirsute, minutely glandular. |
