Leaf rosettes 3--13 mm in diam. Leaves sessile, only obscurely dimorphic. Outer leaves withered, becoming deep reddish brown in anthesis, linear to ligulate-oblong, (2--)3--5 X 1--1.5 mm, glabrous, margin remotely ciliate, apex obtuse. Inner leaves spatulate-oblanceolate to oblong-spatulate, 5--9 X 1--1.5 mm, glabrous or sparsely hirtellous along abaxially raised midvein, pectinate-ciliate, apex obtuse to acute. Scapes solitary, 0.5--2.5 cm, with spreading or slightly tangled long white hairs and minute glands; umbels 5-or 6-flowered; bracts sometimes purplish, elliptic to oblong, 5--6 X 1.5--2.8 mm, usually conduplicate, sparsely villous and long ciliate. Pedicel 1--3 mm. Calyx ca. 3 mm, parted to middle; lobes ovate to ovate-triangular, sparsely villous and ciliate, apex obtuse.
