Perennials 50–120(–150) cm (with caudices or stout rhizomes). Stems ascending to erect, glabrate or pilose, eglandular to ± densely glandular. Leaves: mid and distal blades elliptic to lance-ovate, 5–10 cm × 15–35 mm, faces glabrous and eglandular to adaxially villous and/or ± glandular. Heads 5–15(–40) in racemiform to corymbiform arrays. Peduncles often stipitate-glandular. Involucres turbinate, 7–10 mm. Phyllaries in 4–6 series (strongly unequal, often reddish apically), linear to lance-ovate, acute to acuminate, pubescent to glandular or glabrate abaxially, villous adaxially, especially distally (appearing ciliate toward tips). Rays usually 8 or 13, white to pink. Cypselae usually pilose; pappus bristles in 2 series, barbellate. 2n = 18.


Phenology: Flowering Jul–Aug.
Habitat: Open coniferous forests, montane and subalpine meadows
Elevation: 500–3000 m
