Treatment appears in FNA Volume 21. Treatment on page 86. Mentioned on page 84.

Plants 10–30 cm. Stems (erect) usually branched. Leaves crowded near stem-bases; petiolate; blades usually lyrate, sometimes pinnatifid, slightly chartaceous, ultimate margins entire, faces sparsely hirsute (at least adaxial). Heads in corymbiform arrays. Peduncles hairy (hairs relatively fine and usually mixed with shorter, stouter hairs). Involucres 16–22 mm diam. Ray corollas yellow to orange-yellow, abaxial veins green, laminae 12–17 × 5.5–7.8 mm. Disc corollas red to maroon. Cypselae (obovate) 5–6 × 3–4.5 mm. 2n = 30.


Phenology: Flowering Mar–Jun(–Dec).
