Outer florets pistillate, in many series, fertile, slender, corollas 3- to 5-toothed. Central disc florets bisexual, fertile, slender, many, corolla-limb slightly dilated, 4- or 5-toothed, yellowish. Base of anthers sagittate, with slender tails. Style branches of central florets linear, rather flat, obtuse.
