Synflorescences cymose, lax, ± flat-topped, sometimes reduced to single capitulum. Capitula pedunculate, heterogamous, radiate. Involucres coryliform; phyllaries in 3 or 4 rows, scarious margins white or brown. Receptacle convex, sometimes conical, epaleate. Marginal florets in 1 row, female, fertile; lamina white or pink, rarely yellow. Disk florets many, yellow, bisexual; corolla tubular, apex 5-lobed. Anther bases obtuse; apical appendage ovate-lanceolate. Style branches linear, apex truncate. Achenes 10-ribbed, ribs projected or not to apical rim. Corona or adaxial auricle present or not.

Leucanthemum maximum (Ramond) Candolle (Prodr. 6: 46. 1838; Chrysanthemum maximum Ramond, Bull. Sci. Soc. Philom. Paris 2: 140. 1800; 大滨菊 da bin ju), native to SW Europe, is grown in China as an ornamental garden plant. It is closely related to L. vulgare but is a larger plant with more acutely toothed leaf margins and wider scarious phyllary margins.

Thirty-three species: Europe; one species (introduced) in China.
