Characteristics

Perennial herb, rootstock woody, some silky-brown wool hidden in the axils of the leaf bases, stem solitary, simple, erect to ±500 mm, white-woolly, leafy below, becoming bracteate upwards. Leaves mostly radical, mostly 80-130 x 20-40 mm, elliptic, apex acute, tapering below to a broad, flat, clasping petiole-like base, upper surface glabrous, lower with a white silky-woolly-felted skin-like indumentum, stem leaves similar but soon sessile, passing rapidly into distant linear-lanceolate acuminate bracts. Heads homogamous, campanulate, ±7-8 x 6-8 mm, many in a compact or loose terminal corymbose panicle. Involucral bracts in ±5 series, graded, inner about equalling flowers, loosely imbricate, oblong, loosely woolly below, tips pellucid, subacute, reddish brown, crisped, not radiating. Receptacle with fimbrils exceeding ovaries. Flowers 30-65. Achenes not seen, ovaries glabrous. Pappus bristles many, about equalling corolla, scabrid, bases lightly fused.
