| Perennials, 3–15 cm; taprooted, caudices branched. |
Perennials (sometimes flowering early and appearing annual or biennial), 8–40 cm; usually taprooted (taproots woody or lignescent, early season forms sometimes fibrous-rooted), caudices usually woody, sometimes branched. |
erect (bracteate), evenly hispidulous to hirsute, usually minutely glandular. |
(often multiple from bases; of previous year often persistent) ascending to spreading (proximally reddish in early season, sometimes proximally woody or lignescent), loosely strigose to villous (proximal hairs sometimes spreading), often sparsely glandular. |
mostly basal (in tufts, persistent) (petioles prominently ciliate, hairs spreading, thick-based); blades linear to linear-oblanceolate, 40–70(–90) × 1–3 mm, cauline reduced to bracts (bases relatively thin, not sheathing), margins entire, coarsely ciliate, faces hispidulous to loosely strigose. |
basal (often withering by late flowering) and cauline; blades oblanceolate to spatulate, 20–50(–100) × 3–7(–18) mm, gradually reduced distally, margins entire or with 1–2(–3) pairs of teeth, faces loosely strigose (hairs ascending), eglandular. |
(3.5–)4.5–7.5 × 9–17 mm. |
3–4.5 × 6–9(–12) mm. |
|
24–65(–170); corollas white, often with abaxial midstripe, often drying lilac, 4–7(–11) mm, laminae not coiling or reflexing. |
20–60; corollas tubular, lacking laminae, or laminae yellow (sometimes fading on drying and appearing whitish or creamy), 2–10 mm, not coiling or reflexing. |
|
4–4.5 mm (throats tubular). |
1.7–3.1 mm (throats indurate and slightly inflated). |
in 2–3 series, sparsely hispid, minutely glandular. |
in 2–3 series, sparsely to moderately hirsute, minutely glandular. |

1(–3+, –50 in later season, branches at first from midstem or proximally, later more distal). |
2–2.5 mm, 2-nerved, faces sparsely strigose (carpopodia yellowish); pappi: outer of inconspicuous setae, inner of 15–25 bristles. |
1.1–1.4 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of (5–)12–17 bristles. |

Varieties 3 (3 in the flora). Intermediates between var. austiniae and var. chrysopsidis are formed in Oregon and Idaho, where their ranges overlap. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erigeron modestus is a polyploid complex apparently incorporating genes from E. flagellaris, E. tracyi, elements of E divergens, and the Mexican E. pubescens Kunth; arbitrary identifications may be necessary. In most of its range in Texas, E. modestus is not sympatric with any of those other taxa. Forms flowering in early season (Mar–Apr) often have stems red at the bases, dentate basal leaves 30–60(–100) × 5–10(–18) mm, and single, relatively large heads (involucres 9–12 mm diam, ray florets 50–170, corollas 6.5–11 mm) on ebracteate peduncles 5–15 cm. Later season plants have nearly intricately branched stems with more numerous, much smaller, diffusely arranged heads. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
