angular fleabane, bitter fleabane, swamp boreal-daisy, swamp fleabane, vergerette élevée

sticky tall fleabane, Vreeland's erigeron

Habit Biennials or short-lived perennials, (6–)10–40(–50) cm; fibrous-rooted, caudices simple or branched, or rhizomes. Perennials 30–80 cm; rhizomatous to subrhizomatous, fibrous-rooted, caudices usually relatively short and few branched, thick, woody.
Stems

erect, sparsely to moderately strigose or loosely strigoso-villous or glabrate, often minutely glandular near heads.

erect, sometimes sparsely pilose (hairs 1–2 mm), densely stipitate-glandular.

Leaves

basal (persistent) and cauline;

basal blades oblanceolate to spatulate, 20–80 × 2–6 mm;

cauline gradually reduced distally, margins usually entire, rarely dentate, glabrous or sparsely villoso-hirsute, distal sometimes also glandular.

basal (usually withering by flowering) and cauline;

basal blades oblanceolate-spatulate, 30–80 × 5–20(–25) mm (bases usually clasping to subclasping), margins entire, faces glabrous, densely stipitate-glandular;

cauline blades narrowly lanceolate to oblong-, ovate-, or elliptic-lanceolate, nearly even-sized distally or sometimes mid largest (continuing to immediately proximal to heads).

Involucres

5–11 × 8–12 mm.

6–9 × 10–15(–18) mm.

Ray florets

75–150;

corollas blue to lavender, 9–17 mm (ca. 1 mm wide), laminae coiling.

Ray (pistillate) florets

in 2 series: outer 45–60, corollas white to pink, 5–7 mm, laminae (filiform) erect, not coiling or reflexing;

inner far fewer than outer, elaminate.

Disc corollas

4.2–6.2 mm.

3–4 mm.

Phyllaries

in 2–3 series (inner apices attenuate to caudate), sparsely hirsute to villoso-hirsute, eglandular or sparsely minutely glandular only at tips.

in 2–3(–4) series, densely stipitate-glandular.

Heads

1–5(–8) in corymbiform arrays (on straight, spreading peduncles).

1–15(–22) in corymbiform arrays.

Cypselae

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

pappi: outer of setae, inner of 24–35 (accrescent) bristles.

1.7–2 mm, 2-nerved, faces sparsely strigose;

pappi: outer of (conspicuous) scales, inner of 14–22 bristles.

Discussion

Erigeron vreelandii is similar to E. speciosus in its perennial duration, tall stature, subclasping, spreading leaves nearly even-sized up the stems, corymbiform arrays, and blue rays; it is distinguished by the prominent vestiture of relatively long stipitate-glandular hairs. Intermediates apparently are formed between the two.
