    basal blades spatulate to broadly or narrowly oblanceolate to linear, (10–) 30–150 (–170) × 5–15 (–21) mm, cauline usually gradually reduced distally, continuing to near heads, margins entire or shallowly to deeply serrate or crenate, faces glabrous or glabrate to sparsely strigose or strigoso-hirsute, eglandular.
    Heads 10–200+ in loosely corymbiform to paniculiform-corymbiform arrays (on distal branches).
    Involucres (2–) 3–4 × 5–12 mm.
    Ray-florets 50–100;
