Capitula in dense compound corymbs 15–60 mm across, branches 15–40 mm long, inflorescence bracts linear to lanceolate, 5–10 × 1–3 mm. Involucre subglobose, 5–8 × 10–15 mm, densely whitish woolly; outer bracts ovate, 2–3 × 1–2 mm, attenuate, with dark markings apically, margins minutely serrulate. Receptacle paleate.
