Ray corolla laminae abaxially yellow to orange (often marked with purple), adaxially mostly yellow to orange (sometimes purplish at bases and/or apices), 15–20(–30+) mm. Disc florets 15–50+; corollas yellow to orange, usually purplish distally, 4–5 mm (lobe apices acute, terete, or dilated). Ray cypselae 4–5 mm; disc cypselae 6–8 mm. 2n = 18.

Discussion
Plants treated here (and in horticultural trade) as Dimorphotheca sinuata are sometimes called “D. aurantiaca Hort., non de Candolle” and/or “D. calendulacea Harvey.” But for corolla colors, plants of D. sinuata are not easily distinguished from plants called D. pluvialis. They may prove to be better considered a color form of D. pluvialis.
