Stems erect, moderately to densely hirsute to hirtellous (hairs retrorsely spreading), usually eglandular, sometimes sparsely minutely glandular. Leaves basal (and proximal cauline usually withering by flowering) and cauline; basal and proximal cauline blades elliptic-ovate to spatulate-obovate, 18-135 × 6-27 mm, margins entire to mucronulate or shallowly serrate, faces short-strigose to hirsute or hirsuto-villous; cauline blades becoming lanceolate and entire distal to midstems, nearly even-sized distally or mid largest (bases clasping to subclasping). Heads 1-6 (from branches on distal 1 / 3 - 1 / 2 of stems). Involucres 6-8 × 9-15 mm. Phyllaries in 3(-4) series, moderately piloso-hirsute, usually eglandular, sometimes minutely glandular. Ray florets 47-99; corollas 11-20 mm, laminae coiling at tips, white, drying white or lilac-tinged. Disc corollas 3.4-4.6 mm. Cypselae obovate to 1.8-2.1 mm, 2(-4)-nerved, faces sparsely strigose; pappi: outer of setae, inner of 20-32 bristles. 2n = 18. Flowering Jul-Sep.
