Perennials, 5–8 cm; taprooted, caudex branches relatively short, thick, retaining old leaf bases. |
first erect (greenish proximally; usually single, simple), then producing herbaceous, leafy, prostrate runners (usually with rooting plantlets at tips, populations often becoming clonal mats), strigose (often sparsely; hairs antrorsely appressed, consistent in orientation), sometimes slightly glandular distally. |
erect (greenish), closely strigose (hairs white, equal), eglandular. |
basal (often persistent) and cauline; basal blades broadly oblanceolate to elliptic, 20–55 × 3–9 mm; cauline abruptly reduced distally, margins entire or dentate, faces strigose, eglandular. |
basal (persistent, persistent portions relatively short and broad) and cauline (petioles erect, greenish, bases broadened or not, not thickened and whitish-indurate); blades linear, 12–30 × 0.5–0.8 mm, cauline unreduced for ± 1/2 stems, margins entire, eciliate, faces sparsely strigose, eglandular. |
3–5 × 6–13 mm. |

40–125; corollas white, often with an abaxial midstripe, often drying lilac, 4–10 mm, laminae not coiling or reflexing. |

Early season forms of Erigeron flagellaris may consist of a basal rosette and a single, erect, scapiform, monocephalous stem; leafy runners usually develop quickly. Many polyploids of this species are indistinguishable from diploids; some polyploids have features suggestive of genetic influence of E. tracyi.
