Stems 40–95 cm. Leaves and stems glabrous or hispid (stems 0–25 hairs/mm2; leaves 0–20 hairs/mm2). Leaves: basal to 250 × 40 mm; mid to distal lanceolate to ovate, sometimes rhombic, thin. Heads usually compact, flat-topped arrays (2–) 4–14 (–24) × 5–15 (–24.5) cm. Peduncles sparsely to moderately hispid. Phyllaries outer glabrous; inner linear-oblanceolate, 0.8–1.4 mm wide, glabrous. Disc corolla lobes 1–1.6 mm. Cypselae glabrous. 2n = 18.


Phenology: Flowering Sept–Oct(–Nov).
Habitat: Prairies, glades, savannas, dry open areas, especially on calcareous soils
