Leaves basal, occasionally in rosettes; petiole 0.3-1.5 cm, tomentose; blade narrowly elliptic, (0.5-)1-2 × 0.2-0.5 cm, densely white-lanate or grayish-tomentose abaxially, floccose and green adaxially, margins entire, usually slightly revolute. Inflorescences subcapitate or umbellate, 0.5-1.5 × 0.3-2 cm; branches tomentose to floccose; bracts 5-7, semileaflike at proximal node, 0.4-1 × 0.1-0.3 cm, often absent immediately below involucre. Involucres 1 per node, narrowly turbinate to turbinate-campanulate, 3-5 × 3-4.5 mm, tomentose to floccose; teeth 5-8, erect, 0.2-0.5 mm. Flowers (3.5-)4-5(-6.5) mm, including 0.1-0.2 mm stipelike base; perianth pale yellow, sparsely pubescent abaxially; tepals monomorphic, narrowly oblong; stamens exserted, 4-5 mm; filaments pilose proximally.
