Receptacle flat to conical, paleate; paleae as long as disc florets and somewhat enclosing them, linear to lanceolate, sometimes fimbriate, membranous. Ray florets neuter or female, fertile or sterile; corolla white, with +/- cylindrical widening tube; lamina entire or bifid, longer than tube. Disc florets bisexual, sometimes sterile; corolla yellow, tubular, gradually widening upwards, lobes 5, ovate-triangular, thickened at apex. Anthers linear with sterile, flat, ovate to oblong, rounded to truncate, apical appendage; tails flat, subulate, +/- connate in pairs.
