Cauline leaves: blades (green) ovate-lanceolate to deltate, 6–15 cm, bases truncate or subcordate, margins entire or serrulate to crenate, faces sparsely hispid or scabrous (and finely gland-dotted, often vernicose). Heads held beyond or among the leaves. Involucres hemispheric, 15–30 mm diam. Outer phyllaries oblong to lanceolate or oblanceolate, 12–20+ mm (± equaling discs, tips usually spreading to squarrose). Ray florets 10–16(–21), laminae 20–25 mm. Cypselae ca. 6 mm, glabrous; pappi coroniform, 0.1–1 mm. 2n = 38.
