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). Heads 1-15(-22) in corymbiform arrays. Involucres 6-9 × 10-15(-18) mm. Phyllaries in 2-3(-4) series, densely stipitate-glandular. Ray florets 75-150; corollas blue to lavender, 9-17 mm (ca. 1 mm wide), laminae coiling. Disc corollas 3-4 mm. Cypselae 1.7-2 mm, 2-nerved, faces sparsely strigose; pappi: outer of (conspicuous) scales, inner of 14-22 bristles. 2n = 18. Flowering Jul-Sep(-Oct). Openings and open woods, oak-pine, ponderosa pine, pine-fir; (1300-)1800-3100 m; Ariz., Colo., N.Mex.; Mexico (Sonora). 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.
