--><span class="statement" id="st-undefined" data-properties=""><b>Biennuals </b>or short-lived perennials, 3–15 cm; usually fibrous-rooted, sometimes taprooted, caudices lignescent, rarely branched. <b>Stems</b> 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. <b>Leaves</b> 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. <b>Heads</b> 1(–3, on proximal branches). <b>Involucres</b> 3–5 × 6–13 mm. <b>Phyllaries</b> in 2–3 series, strigose to loosely hirsute, minutely glandular. <b>Ray</b> florets 40–125; corollas white, often with an abaxial midstripe, often drying lilac, 4–10 mm, laminae not coiling or reflexing. <b>Disc</b> corollas 2–3.5 mm. <b>Cypselae</b> 0.8–1.3 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 10–17 bristles. <b>2n</b> = 18, 27, 36, 45, 54.</span><!--

|discussion=<p>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.</p>
