| Perennials, 1.5–5(–7) cm (forming densely compact cushions); taprooted, caudex branches rhizomelike, relatively numerous, short, and slender. |
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 (simple, scapiform), sparsely to densely hirsuto-villous, 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. |
basal (persistent; petioles linear, 0.5–1 mm wide); blades obovate-spatulate, 3–16 × 3–6 mm (bases abruptly expanded), margins mostly 3-lobed, rarely entire or 2-lobed (lobes 2–8 mm, oblong to ovate or obovate, rounded), ultimately entire, coarsely ciliate, faces sparsely to densely hirsute, ± 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. |
5–7 × 8–11 mm. |
3–4.5 × 6–9(–12) mm. |
15–32; corollas white to bluish, 6–10 mm, laminae not coiling or reflexing (spreading). |
24–65(–170); corollas white, often with abaxial midstripe, often drying lilac, 4–7(–11) mm, laminae not coiling or reflexing. |
3.2–4.5 mm. |
1.7–3.1 mm (throats indurate and slightly inflated). |
in 2–3 series (commonly purplish, sometimes at tips only), sparsely to densely hirsuto-villous to villous (hairs usually with colored cross walls), 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). |
2–2.6 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of 15–21 bristles. |
1.1–1.4 mm, 2-nerved, faces sparsely strigose; pappi: outer of setae, inner of (5–)12–17 bristles. |

Of conservation concern. The compactly cespitose, cushionlike habit of Erigeron salishii may obscure the slender, loose branches of the caudex in herbarium specimens. The species otherwise is similar to E. vagus; the leaves of E. salishii are mostly smaller and the hairs thinner and looser (villous) compared to those of E. vagus.

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.) |
