Capitula terminal, solitary, but sometimes the whole plant forming a lax corymb, individual capitula 4–8 mm long; peduncle 1–10 cm long, sparsely pubescent to glabrous, often sparsely glandular, sometimes densely so near the head; phyllaries in ± 4 rows, ± 30–35, the outermost smallest, lanceolate, 1–4 mm long, 0.2–0.6 mm wide, acute, sparsely hairy, with scarious and often fimbriate margins; receptacle convex. Ray florets 25–30, the tube ± 1 mm long, the ray pale blue-mauve, rarely whitish, 4–7 mm long and 0.9–1.1 mm wide; disc florets many, yellow, the tube 2.3–2.7 mm long, the lobes 0.2–0.5 mm long, anthers 0.7–0.9 mm long, style 2.6–3.5 mm long.
