Drosera praefolia

''Drosera praefolia'' is a perennial tuberous species in the genus ''Drosera'' that is endemic to South Australia. It grows in a rosette 4 to 6 cm in diameter with green or sometimes red leaves. It is native to south-east South Australia from the southern Fleurieu Peninsula south to Kangaroo Island. It grows in lateritic clay-sand, loam, or decomposed shale soils in open woodland. It flowers from April to May.〔Lowrie, A, and J. G. Conran. 2008. (A review of ''Drosera whittakeri'' s. lat. (Droseraceae) and description of a new species from Kangaroo Island, South Australia ). ''Telopea'', 12(2): 147-165.〕
It was first formally described by Johann Gottlieb Otto Tepper in 1892 from specimens he collected on the Fleurieu Peninsula. Earlier in 1882, Tepper sent a description and specimens to Ferdinand von Mueller, who labeled the plants as ''D. whittakeri'' var. ''aphylla'', but never published the name. Its placement at the rank of species was controversial and several authors, including Raymond Hamet in 1907, John McConnell Black in 1924, and Allen Lowrie in 1989, have reorganized it below the species rank. Others have reduced it to synonymy with ''Drosera whittakeri''. In 1991, Robert J. Bates made the case for recognition at the species rank, authoring the illegitimate name ''D. aphylla'' in the process, a name not based on the first validly published description. Recently, several authors have recognized the taxon at the subspecies or species rank, but others have still only recognized it as a part of the very variable single species ''D. whittakeri'' ''sensu lato''. In a review of ''D. whittakeri'' and related species, Lowrie and John Godfrey Conran reestablished it at the species rank, arguing that the morphology is dissimilar enough from ''D. whittakeri'' that it requires its own species epithet. Lowrie and Conran note that ''D. praefolia'' is distinct from ''D. whittakeri'' (whose opposing characteristics presented in parentheses) by its white tubers (orange), leaves emerging after flowering (before flowering), and the ovate to obovate leaf shape (broadly spathulate), among other differences.〔
