The flowerheads of Dimorphotheca sinuata grow solitary on slender, erect peduncles bearing stem-leaves.
The single whorl of ray florets is pale orange to orange-yellow or pale beige with a small dark part at the base. The disc is blackish until its tiny, orange florets open. One row of narrow, free involucral bracts form a shallow cup, the flowerhead base. The daisy diameter is 4 cm to 5 cm.
Flowering happens from late winter to after midspring, starting earlier depending on rain. The fruits are disc-like, brown and papery (Manning, 2009; Le Roux, et al, 2005; Manning and Goldblatt, 1997; iNaturalist; http://pza.sanbi.org).
