Taxonomic notes: C. erythraea can usually be distinguished from C. tenuifiorum by its calyx which is half to two-thirds the length of the corolla tube. That is, the corolla tube keeps on elongating after anthesis so that the calyx is ultimately about half the length of the corolla tube in fruiting specimens while it might reach two-thirds in some specimens of C. tenuiflorum. Other characters often used to separate the species pair are the longer corolla lobes and the presence of a distinct basal rosette in C. erythraea but these were found less reliable for S.Aust. plants. Also, specimens from S.Aust. cannot be definitely placed into one of the six subspecies recognised by Melderis (1972), Fl. Europaea 3:58.
