Drosera erythrorhiza D. erythrorhiza (or D. erythrorhiza ssp. erythrorhiza) is one of four species in the erythrorhiza complex consisting of D. collina, D. erythrorhiza, D. magna and D. squamosa. It is a rosetted species usually forming 3-5 active leaves per rosette. The plants mostly reach 6 to 8 cm in diameter. D. erythrorhiza rarely flowers and needs a bush fire to induce flowering. However, this species reproduces well by formation of lateral adventitious stolons.The tubers are orange. I am still not sure whether I can tell apart all the different plants within the D. erythrorhiza complex. Two species form few leaves: D. erythrorhiza usually 3-5 per rosette, D. magna 4-6, and both can be distinguished by their size, as D. erythriza usually reaches no more than 6 to 8 cm in diameter, whereas D. magna forms rosettes of about 10 to 12 cm. The other two species produce larger numbers of active leaves: D. squamosa 7 to 8 per rosette, D. collina even 10 to 12. D. squamosa leaves usually have a typical red margin, but this feature may be missing in some plants of a given colony. Those can be very difficult to distinguish from D. collina. Drosera erythrorhiza I will add some pictures of this species soon.Drosera erythrorhiza var. imbecilia This is a variant currently considered part of the D. erythrorhiza description.Please note that I mispelled the name in the past. The correct spelling is used here. Please update your lists accordingly.
