    Cotula discolor flowerhead
    Author: Ivan Lätti
    Photographer: Francelle van Zyl

    A Cotula discolor flowerhead grows solitary on an erect peduncle from a stem-tip. The peduncles are from 1 cm to 14 cm long.

    There are no ray florets. The many tubular, four-lobed yellow florets form a convex yellow disc, up to 17 mm in diameter. Some of the outer rows of florets are female around the rest, the bisexual florets of the disc centre. The outermost ring of female florets enlarge the outer lobes of their tubes. They appear somewhat like ray florets, but are not that, known as mere pseudo-rays.

    There are two or three rows of bracts around all the florets inside the hemispherical involucre over a shallowly convex receptacle (Manning and Mucina, 2013: Cotula discolor. African Journal of Botany, 88, 240; iNaturalist).
