Drosera squamosaD. squamosa (or D. erythrorhiza ssp. squamosa) 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 7 to 8 active leaves per rosette. The plants mostly reach 6 to 10 cm in diameter. D. squamosa seems to flower without pre-season bush fires. However, this species rarely reproduces 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.
