Leaves: basal and proximal cauline tapering to winged petioles, blades oblanceolate to ovate, 35–210 × 15–50 mm, margins serrate or crenate, apices acute, sparsely to moderately soft hispido-villous, more densely so on abaxial nerves; rosettes on rhizome branches sometimes present at flowering; mid and distal cauline sessile, blades elliptic, 15–50 × 5–15 mm, distally reduced, margins entire. Heads 12–270 (1–15 per branch) in usually wand-shaped paniculiform arrays, of short axillary and terminal racemiform, non-secund clusters, sometimes proximal branches elongated, ascending and bearing short axillary and terminal racemiform clusters. Peduncles 1.5–2.5 mm, hispido-villous to canescent. Involucres campanulate, 3–5 mm. Phyllaries in 3–4 series, appressed, strongly unequal, oblong, margins white, scarious, apices obtuse to rounded.
