Treatment appears in FNA Volume 20. Treatment on page 250. Mentioned on page 249, 251, 252, 256.

Stems decumbent to erect, 16–39 cm, moderately to densely strigose, sparsely to abundantly long-hirsute, eglandular or sparsely stipitate-glandular. Distal cauline leaf-blades oblanceolate, 21–35 × 3.5–6 mm, bases narrowly cuneate to attenuate, margins flat, apices acute, faces moderately strigose (20–60 hairs/mm2), eglandular or sparsely stipitate-glandular. Heads 1–12 (–25). Peduncles (5–) 12–47 (–67) mm, sparsely to densely hispido-strigose, eglandular; bracts subtending heads usually none, rarely linear-oblanceolate, leaflike. Involucres narrowly cylindric to campanulate (fresh), (5–) 6–9 (–11) mm. Phyllaries narrowly triangular-lanceolate, margins usually reddish purple distally, faces moderately to densely strigose, eglandular. Ray-florets 10–27 (–38), laminae (6.5–) 8.5–15 (–20) mm. 2n = 18, 36.


Phenology: Flowering (May–)Jun–Oct(–Nov, south).
Habitat: Silty, sandy loam or clay soils, chalk, or granitic soils, gravel soils, dry shale-limestone soils, red sandstone soils, travertine soils of sandhill prairies, pastures, grasslands, roadsides, railroad rights-of-way
Elevation: 300–2300(–2900) m
