These Senecio arenarius flowerheads have bold-looking yellow discs pushed forward, the spaced, narrow, mauve ray florets bent back like shuttlecock feathers shaped for flight.

The bases of the rays are whitish here, their tips obscurely toothed. The one row of bracts forming a cylindrical involucre as the flowerhead base is quite hairy, the hairs gland-tipped.

The photo was taken in August near Nieuwoudtville (Manning, 2007; iNaturalist).
