| Perennials, 3–15 cm; taprooted, caudices simple or with relatively short and thick branches. |
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, sometimes branched, hirsute (hairs unequal), ± 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 (persistent; petioles prominently ciliate, hairs spreading, thick-based); blades narrowly oblanceolate to spatulate, (20–)30–80 × 2–4(–12) mm, cauline sometimes continuing distally to about midstem, margins entire, usually ciliate, sometimes coarsely so, faces sparsely to densely hirsute, sometimes minutely glandular. |
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. |
5–9 × 9–20 mm. |
3–4.5 × 6–9(–12) mm. |
15–45 or 0; corollas usually pink to bluish purple, sometimes white, 5–14 mm, laminae coiling. |
24–65(–170); corollas white, often with abaxial midstripe, often drying lilac, 4–7(–11) mm, laminae not coiling or reflexing. |
(3.5–)4–5.5 mm. |
1.7–3.1 mm (throats indurate and slightly inflated). |
in 2–3 series, sparsely to densely hirsuto-villous to hirsute, minutely glandular. |
in 2–3 series, sparsely to moderately hirsute, minutely glandular. |
1(–3) (from branches at or proximal to midstem). |
1(–3+, –50 in later season, branches at first from midstem or proximally, later more distal). |
2.5–3 mm, 2-nerved, faces densely strigoso-sericeous (obscured); pappi: outer of setae, inner of 20–30 bristles. |
1.1–1.4 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of (5–)12–17 bristles. |

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.) |
