Herbs, perennial, woody caudex shortly branched. Stems (5-)35-100 cm tall, erect, usually slender, solitary or rarely fascicled, simple or branched in upper part. Leaves: lower cauline 1-25 (including petiole) × 0.4-3(-4) cm, petiole 2-4 cm or more, with long wings, blade lanceolate to ovate, both surfaces puberulent or adaxially glabrous, upper margin serrate or entire; mid cauline petiole winged, blade elliptic, long elliptic, ovate, or broadly lanceolate, 2-14 × 0.4-2(-2.9) cm, base cuneate-attenuate, upper margin serrate, serrulate, or entire; upper cauline length from widest point to apex 6.5-31.5 mm, mean 14.3 mm. Capitula numerous in terminal, dense or lax racemiform or corymbose-paniculiform synflorescences, branches erect, inserted around stem, capitula attached around branch, rarely lower branches elongated terminating in separate synflorescences. Involucre 3.5-6.2(-7.7) mm; phyllaries 4-6-seriate, lanceolate or narrowly lanceolate, apex acute or acuminate. Ray florets 2-9, lamina 2-5(-6.5) × 0.9-2.8 mm. Achenes 2-3 mm, glabrous to sparsely strigose Pappus bristles 3.1-5.2 mm, inner (longest) weakly to moderately clavate. Fl. and fr. Apr-Nov.
