Davis' daisy, Davis' fleabane

Perennials, 10–30 cm; taprooted, caudices simple or with relatively short, thick branches. |
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, hirsuto-villous to loosely strigose (hairs relatively translucent and vitreous, unequal in lengths, 0.1–1 mm), sometimes sparsely minutely glandular. |
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. |
mostly basal (persistent; petioles prominently ciliate, hairs spreading, thick-based), eglandular; blades linear to narrowly oblanceolate, 20–100 × 1–3.5 mm, abruptly reduced distally, margins entire, faces strigose to strigoso-hirsute, eglandular. |
3–5 × 6–13 mm. |
5–8 × 10–15 mm. |
40–125; corollas white, often with an abaxial midstripe, often drying lilac, 4–10 mm, laminae not coiling or reflexing. |
50–80; corollas usually white, 8–14 mm, laminae (1.2–1.8 mm wide) coiling. |
2–3.5 mm. |
3.1–4 mm (glabrate, throats not indurate or inflated). |
in 2–3 series, strigose to loosely hirsute, minutely glandular. |
in 2–3 series, loosely hirsute to hirsuto-villous, sometimes sparsely minutely glandular. |
1(–3, on proximal branches). |

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.
