Small annual herbs, acaulous, with slender rhizomes. Stems slender, erect, 8–15 cm tall, scape-like, with 2–4 remote linear bracts, bracts 2–3 mm long, suglabrous.
Leaves basal, rosulate, obovate to broadly spatulate, 1.2–3×0.6–1.2 cm, apex rounded or obtuse, base cuneate, short petiolate, shallowly undulate or broadly mucronate toothed, rather densely pubescent to pilose.
Heads hemispheric, 3–5 mm across, solitary, scapes much longer than leaves. Involucre hemispheric, bracts in 2 or 3 series, oblong-lanceolate, acute, scarious-margined, often purplish. Ray florets many, in 2 or 3 rows, white ligule narrow, extruded, ca. 1.5–2 mm long; corolla about as long as extended ligule. Disc florets few, bisexual but functionally staminate, corolla campanulate, ca. 2.5 mm long, 4-lobed.
Achenes oblanceolate, compressed, ca. 2.5 mm long, tapering into a short glandular beak, glabrous.
