4. Wyethia amplexicaulis (Nuttall) Nuttall, Trans. Amer. Philos. Soc., n. s. 7: 352. 1840.

Espeletia amplexicaulis Nuttall, J. Acad. Nat. Sci. Philadelphia 7: 38. 1834; Wyethia amplexicaulis subsp. major Piper; W. amplexicaulis subsp. subresinosa Piper; W. lanceolata Howell

Plants 25 50(—100) cm. Basal leaves: blades (green, shining) lance-elliptic or oblong-lanceolate to lanceolate, 15—30(—40+) cm, margins usually entire, sometimes denticulate or dentate, not ciliate, faces glabrous (gland-dotted, vernicose); cauline leaves similar, smaller distally (distalmost sessile, usually ± clasping). Heads usually 2—8 in ± corymbiform to racemiform arrays, sometimes borne singly. Involucres hemispheric to turbinate, 15—30 mm diam. Phyllaries 18—36+, subequal or unequal, herbaceous (at least outer), margins not ciliate, faces glabrous; outer 18—32 mm (surpassing inner). Ray florets 8—21(—25); laminae 25—60 mm. Cypselae 8—9 mm, glabrous. 2 n = 38.

Flowering May—Jul. Wet to dry, open sites, meadows, sagebrush scrub, yellow-pine forests; 400—3000 m; Colo., Idaho, Mont., Nev., Oreg., Utah, Wash., Wyo.

Wyethia amplexicaulis introgressively hybridizes with W. arizonica (producing plants called W. × magna A. Nelson ex W. A. Weber) across a broad area of central and southern Colorado. Habit of the hybrid is typical of W. amplexicaulis ; the indument resembles that of W. arizonica in varying degrees. Occasionally, W. amplexicaulis hybridizes with but does not introgress with W. helianthoides .
