Deep-rooted perennial herb 15-50 cm tall with a woody rhizome or rootstock; stems several, branched or unbranched, erect to ascending, with a sparse to moderately dense vestiture of woolly-cobwebby hairs and scattered inconspicuous glandular hairs; leaves linear-elliptic to narrowly oblanceolate or linear, with narrowly recurved margins, acute softly mucronate apex and a broadly sessile base, mostly 2-5 cm long, 1-5 mm wide, discolorous, on the upper side sparsely (rarely moderately) cobwebby-hairy, on the underside densely woolly-cobwebby with scattered minute glandular hairs on both sides.

Capitula terminal and usually solitary on long leafy stems or sometimes 2 or 3 in an open leafy corymb, more or less broadly hemispherical, (the involucre initially with erect to oblique sides but the laminae at length becoming patent to reflexed) 1.5-2.2 cm long and eventually 2.5-3.5 cm diam.; involucral bracts c. 10-seriate, the intermediate ones longest; outermost bracts wholly scarious, white, opaque; intermediate bracts 10-14 mm long and 2-3 mm longer than the florets, for most of their length scarious, opaque, white (sometimes tinged pink in bud), lanceolate, acute, with entire margins and with short broadly linear woolly firm subherbaceous claws; florets numerous, all bisexual; style branches truncate, papillose.

Achenes oblong, angled, more or less square in cross-section, not compressed, glabrous, smooth, pale-brown; pappus bristles 80-100, scarcely connate at the base and falling in groups, smooth at the base, barbellate upwards, coarsely so towards the apex, white.
