Leaves lanceolate or linear-lanceolate, 5-15 × ca. 1.3 mm, with soft lanate pubescence, apex acute. Capitula 2-3 mm, ovate or pyramidal, gathered in 2s-10s into numerous corymbs, arranged at apices of stems and ramuscules and forming paniculate, racemose, more rarely spiciform synflorescences; floral leaves as long as or shorter than capitula. Involucre 2- or 3-seriate; phyllaries stellate-patent after ripening of achenes; outer phyllaries 5-10, closely surrounding female florets, green, in middle scarious, white transparent at margin, linear or lanceolate, cymbiform, 2-3 mm, ecarinate, abaxially with thick continuous gray lanate pubescence, glabrous at apex, slightly acuminate; inner phyllaries 5, becoming green in middle, broadly lanceolate, slightly concave, indistinctly pubescent or glabrous at margin abaxially, acuminate or obtuse. Achenes light brown, oblong-ovate, slightly flattened, 0.8-1 × ca. 0.3 mm, with sparse papillose hairs, larger than in other species of genus.
