Perennials, 2–10 cm; taprooted, caudices multicipital or branches relatively long and thick to relatively slender, lignescent.

Ray florets 15–40; corollas white, 6–10 mm, laminae not coiling or reflexing, straight. Disc corollas 3.6–4.5 mm. Cypselae 3.2–3.5 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 25–35 (stramineous, dull) bristles.

Discussion

Erigeron evermannii is superficially similar to E. leiomerus and is sometimes misidentified as such; the latter has wider, more numerous, and merely glandular phyllaries, reflexing rays, non-folding leaves, and leafier stems.
