Inflorescences umbellate or compound-umbellate, occasionally capitate or even reduced to single involucre, 0.3-2 × 0.3-2 dm; branches floccose; bracts 3-8, semileaflike at proximal node, 0.3-2 × 0.2-1 cm, often scalelike distally. Involucres 1 per node, usually campanulate, 3-7 × 3-8 mm, floccose; teeth 5-8, erect, 0.1-0.5 mm. Flowers 4-8 mm, including 0.7-2 mm stipelike base; perianth yellow, densely pubescent abaxially; tepals dimorphic, those of outer whorl lanceolate to elliptic, 1.5-5 × 1-3 mm, those of inner whorl lanceolate to fan-shaped, 1.5-7 × 2-4 mm; stamens exserted, 2-4 mm; filaments pilose proximally.
