Drosera binata is a species complex, with several named varieties. Lowrie et al. (2017) note that the current taxonomy of the complex is deficient, and that the complex is undergoing revisionary work and that it is likely to change significantly. The name Drosera pedata Pers. pre-dates D. binata and would have nomenclatural priority if it conspecific (Mabberley 2018), but further work is required to determine if this is the case.
