FNA: Erigeron vreelandii

	Erigeron vreelandii
	sticky tall fleabane, Vreeland's erigeron
Habit	Perennials 30–80 cm; rhizomatous to subrhizomatous, fibrous-rooted, caudices usually relatively short and few branched, thick, woody.
Stems	erect, sometimes sparsely pilose (hairs 1–2 mm), densely stipitate-glandular.
Leaves	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	6–9 × 10–15(–18) mm.
Ray florets	75–150; corollas blue to lavender, 9–17 mm (ca. 1 mm wide), laminae coiling.
Disc corollas	3–4 mm.
Phyllaries	in 2–3(–4) series, densely stipitate-glandular.
Heads	1–15(–22) in corymbiform arrays.
Cypselae	1.7–2 mm, 2-nerved, faces sparsely strigose; pappi: outer of (conspicuous) scales, inner of 14–22 bristles.
2n	= 18.

	Erigeron vreelandii
Phenology	Flowering Jul–Sep(–Oct).
Habitat	Openings and open woods, oak-pine, ponderosa pine, pine-fir
Elevation	(1300–)1800–3100 m ((4300–)5900–10200 ft)
Distribution	AZ; CO; NM; Mexico (Sonora) [WildflowerSearch map] [BONAP county map]
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. (Discussion copyrighted by Flora of North America; reprinted with permission.)
