Woody-based herb with short branchlets arising from a multicipital stock, usually just below the soil surface; living leaves in few to numerous rosettes at the tips of branchlets; the whole plant either solitary or forming a loose mat of a few rosettes. Leaf sheaths densely imbricate and compacted into a pseudostem. Leaf lamina up to 100 × 12-70 mm, submembranous though often flaccidly so, leaves usually at first erect, becoming decumbent with age, elliptic, oblong, or occasionally obovate; upper surface sometimes obscurely sulcate, concolorous, pale to mid-green glabrate above when mature except on margin; lower surface dull, thinly covered in cream-coloured tomentum, veins obscure; tip acute; margins entire, flat, with a very narrow rim of hairs slightly darker than those of lower surface; base rounded to truncate; petiole up to and occasionally exceeding lamina length, green to purple, clad in floccose, whitish hairs. Scape purple, clad in whitish tomentum, up to 400 mm long; bracts numerous, erect, linear sometimes leaf-like; monocephalous. Capitula up to 40 mm diameter. Involucral bracts cream, glabrate, in several series, linear-subulate, erect, glabrate to silky tomentose. Ray florets 70-80, ligulate, the limb linear-lanceolate, white. Disc florets c. 130-170, funneliform, yellow; tube with eglandular, biseriate hairs. Achene fusiform-cylindric, ribbed, 4-5 mm long, glabrous or with scattered bifid hairs.
