Engelmann's fleabane

Habit Perennials 7–35 cm; taprooted, caudex branches relatively short and thick. Perennials, 3–20(–30) cm; taprooted, caudex branches relatively short and thick.
Stems

erect (often silvery white), densely strigoso-villous, eglandular.

erect, loosely to closely, sparsely to moderately strigose (hairs 0.1–0.9 mm), usually minutely glandular (glands barely evident), sometimes eglandular.

Leaves

basal (basal mostly withered or deciduous before flowering, not forming conspicuous tufts) and cauline (leaf bases broadened or not, not thickened and whitish-indurate);

blades linear to linear-oblanceolate, 30–60 × 1–4 mm, cauline abruptly reduced distally, margins entire, faces silvery-strigose, eglandular.

basal (usually persistent) and cauline (petioles prominently ciliate at least on proximal portions, hairs spreading, thick-based);

basal blades linear-oblanceolate, 20–100 × 1–4 mm, margins entire, faces strigose, eglandular;

cauline usually restricted to proximal 1/2 of stems, slightly reduced distally.

Involucres

5–7 × 10–15 mm.

3.5–5(–6) × 7–12 mm.

Ray florets

30–55;

corollas white or pink, 6–13 mm, laminae reflexing.

(35–)45–100;

corollas white, sometimes pink or bluish, 5–10 mm, laminae (0.8–1.1 mm wide) primarily reflexing, sometimes also weakly coiling at the tips.

Disc corollas

3.5–5 mm.

(2.5–)2.7–4.2 mm (throats indurate and inflated, densely puberulent).

Phyllaries

in 3–4 series, glabrous or sparsely strigose proximally, minutely glandular.

in 2–3(–4) series, coarsely hirsuto-villous, sparsely to moderately minutely glandular.

Heads

1–5(–10).

1(–3).

Cypselae

1.8–2.2 mm, 4-nerved, faces sparsely strigose to pilose;

pappi: outer of setae or conspicuous scales, inner of 18–26 bristles.

1.4–1.8 mm (oblong), 2-nerved, faces sparsely strigose;

pappi: outer usually of narrow scales, sometimes 0 or of setae, inner of 12–20 bristles.

Discussion

Of conservation concern.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Plants from Chaffee and Fremont counties, Colorado, have strigose leaves and the compact habit of Erigeron engelmannii but sparsely spreading-hirsute stems; they may be intermediate between E. engelmannii and E. concinnus. Unusual variation in the pappi of E. engelmannii also suggests that the species needs study and better definition.

A. Cronquist observed that “Erigeron engelmannii intergrades completely with E. pumilus, yet has two geographic subspecies of its own, and shows no distributional similarity to the [taxa] of E. pumilus,” and that E. engelmannii is “smaller and more delicate, with shorter finer hairs, and [has] smaller heads with usually fewer ligules.”
