Treatment appears in FNA Volume 19. Treatment on page 474.

Plants 10–40 (–75) cm. Leaves: basal blades lanceolate, (3–) 6–7 cm × 8–20 (–30+) mm; cauline blades lance-elliptic to lance-linear, 2–5+ cm × 5–12 (–20+) mm, bases ± cordate, clasping, margins entire or serrulate (abaxial faces usually villous, adaxial sparsely strigillose to glabrate). Involucres 7–9 (–15) mm diam. Outer phyllaries lance-linear, 4–6 × 0.5–0.8 mm (bases sericeous); inner phyllaries similar, more scarious. Ray-florets 40–70+; corolla laminae 10–15+ mm. Disc corollas 4–6 mm. Cypselae 1–1.5 mm, puberulent or glabrate; pappi of 15–25 distinct or basally connate bristles 4–6 mm. 2n = 32.


Phenology: Flowering mid–late summer.
Habitat: Roadsides, waste places
