Uppermost stem leaves linear, 10-25 × 1-2 mm, usually reflexed, both surfaces densely white lanate, margin entire or denticulate, apex acute. Capitula numerous, in a hemispheric synflorescence 2-3.5 cm in diam., sessile or shortly pedunculate. Involucre cylindric, 4-6 mm in diam. Phyllaries in 3 or 4 rows, membranous, apex acute to acuminate; outer phyllaries narrowly triangular-ovate, 11-13 × ca. 3 mm, apically lanate; inner phyllaries narrowly ovate-elliptic to linear, 9-10 × 1.5-2 mm, apically sparsely pilose.
