Treatment appears in FNA Volume 21. Treatment on page 457.

Plants 30–70 cm (aerial stems branched distally). Leaves mostly basal (distally reduced); basal petiolate; blades 3-nerved, narrowly elliptic to spatulate, 6–25 cm × 8–3 mm. Heads 2–5 (–10), 22–37 mm diam. Peduncles 10–20 cm. Phyllaries 8–11 × 2–3.5 mm, apices acute. Paleae ± linear, apices acute. Corollas pink, lobes 5–7 × 1 mm. Pappi: scale margins irregular, broken, serrulate. 2n = 36.


Phenology: Flowering May–Jun.
Habitat: Meadows, roadsides
Elevation: 500–1000 m

Distribution

Discussion

Marshallia mohrii grows in the southern Appalachians. It may be an allotetraploid derivative of diploids, probably M. grandiflora and either M. trinervia or M. graminifolia subsp. tenuifolia
