Synflorescence a ± flat-topped cyme. Capitula small, heterogamous, disciform. Involucre hemispheric; phyllaries in 4 rows. Receptacle conical, epaleate. Marginal florets female; corolla tapering above, apex minutely 4-toothed. Disk florets apparently bisexual but functionally male, apex 5-lobed, compressed into resinous mass.
