Leucanthemum
The daisy-like flower heads are terminal, mostly solitary, such as in the Shasta Daisy (Leucanthemum x superbum), and rarely a few in corymbs, such as in the Oxeye Daisy (Leucanthemum vulgare). They vary in diameter from 3 to 8 cm. The flowers are pedunculate with involucral bracts and a flat or convex receptacle. They form 2 to 4 whorls. There are about twenty ligulate, white or pinkish ray florets. These are usually female, rarely bisexual. The numerous, tubular, yellow disc florets are bisexual. This genus has an abundant production of 10-ribbed achenes (flat seeds) with mucilaginous cells. The pappus is usually absent, or just a small corona or auricle. Species of this genus also spread vegetatively by rooting underground stems.
