Erigeron piperianus

Piper's fleabane

Blochman's erigeron, Blochman's fleabane, Blochman's leafy daisy

Habit Perennials, (3–)6–12 cm; taprooted, caudices usually branched. Perennials, 4–8 cm, taprooted, caudices woody, branches ascending, sometimes rhizomelike.
Stems

erect (distinctly white in proximal portions), usually strigose at least on distal 1/2, sometimes strigoso-hirsute or mixed-hispid, minutely glandular.

ascending-erect, densely and closely puberulous to villosulous (hairs stiffly crisped, minute), eglandular.

Leaves

mostly cauline (proximal internodes elongate; petioles prominently ciliate, hairs spreading, thick-based);

blades linear to linear-oblanceolate, 20–40 × 1–1.5 mm (on proximal 1/2–2/3 of stems), (bases relatively thin, not sheathing) margins entire, hispido-ciliate, faces strigose.

cauline;

blades linear to narrowly oblanceolate, 15–30 × 1–3 mm, usually even-sized, margins entire, densely and closely puberulous to villosulous, eglandular.

Involucres

3.5–4 × 5–10 mm.

4.5–6 × 9–14 mm.

Ray florets

25–40;

corollas yellow, drying dark yellow (sometimes fading on drying and appearing whitish or creamy), 4–9 mm, laminae coiling.

45–72;

corollas white to bluish, ca. 8–11 mm, laminae not coiling or reflexing.

Disc corollas

2.5–3 mm.

4.6–5 mm (throats slightly indurate, not inflated).

Phyllaries

in 2–3 series, hirsuto-villous, sometimes minutely glandular.

in 3–5 series (with broad, orange middle area and thick, white margins), densely canescent-hirsutulous (hairs crinkly), densely minutely glandular.

Heads

1.

1 or 2–5 in loosely corymbiform arrays.

Cypselae

1.6–1.8 mm, 2-nerved, faces sparsely strigose;

pappi: outer of setae, inner of 15–25 bristles.

2.2–2.8 mm, 2-nerved, faces glabrous;

pappi: outer of setae, inner of 21–36 bristles.
