Involucres campanulate or turbinate. Phyllaries in 3–10 series, appressed, spreading, or reflexed, indurate bases usually glabrous, apices acute to acuminate, 1–3 mm, herbaceous, faces glabrous (indurate bases, sometimes foliaceous parts) or hairy (only foliaceous parts), sometimes stipitate-glandular. Receptacles 2.5–5 mm diam. Ray florets pistillate and fertile, or sterile or 0 (in var. shastensis); laminae white, blue, or purple, 6–12 × 1–3 mm. Disc florets: corollas 4–6(–7) mm.
