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.
