Perennials, (0.6–) 1–12 cm (sterile basal rosettes 1–10+; rhizomes at or below-ground, ± woody, giving rise to branched, woody caudices). Stems (flowering) 1–10+ (1 per rosette), erect, not branched (scapiform), ± villous to woolly, particularly near heads (hairs basifixed). Leaves (basal marcescent, erect) all or mostly basal; alternate; sessile; blades (appearing 1-nerved or nerves inconspicuous) linear, not lobed, margins entire (villous-ciliate), faces glabrous. Heads radiate, borne singly. Involucres hemispheric or broader, (4–) 4.5–6 (–6.5) mm diam. Phyllaries persistent (green), 20–26 (+) in 2 (–3+) series, distinct, oblong to lance-oblong (not carinate, 1-nerved), margins and apices (dark-brown, fimbriate) scarious (apices obtuse to acute, abaxial faces glabrous or villous). Receptacles convex (± villous), epaleate. Ray-florets 11–19, pistillate, fertile; corollas white, laminae obovate. Disc-florets 60–80, bisexual, fertile; corollas yellow, tubes ± cylindric, throats campanulate, lobes 5, deltate (without resin sacs). Cypselae ± obconic, ribs 5, faces glabrous (pericarps without myxogenic cells or resin sacs); pappi crowns of 6–12 irregular teeth. x = 9.
