Drosera stolonifera
Drosera stolonifera, sometimes referred to as the leafy sundew, is a tuberous perennial species in the genus "Drosera" that is endemic to Western Australia. It produces 2 to 3 semi-erect lateral stems that grow 10 to 15 cm long. It is most closely related to "D. purpurascens", but differs by several characteristics including height and petiole length. It is native to a number of swampy locations around Perth south to Pinjarra. It grows in peaty water-logged soils in swamp heathland and flowers from September to October. After a bushfire it will flower "en masse". Taxonomy. The  type specimens were collected by Charles von Hügel in the Swan River region in 1833. "D. stolonifera" was formally described by Stephan Endlicher in his Enumeratio plantarum in 1837. For many years, different varieties and morphs of this species were included in the "D. stolonifera" complex. Several of these forms and varieties were eventually described as subspecies, which were then later elevated to species rank upon further examination. Much of the decision on how to deal with the species complex deals with a discussion of lumpers and splitters. The debate began as early as 1906 when Ludwig Diels reduced Jules  Émile Planchon's "D. humilis" to a variety of "D. stolonifera", thus also creating the autonym "D. stolonifera" var. "stolonifera". Then in 1982 N. G. Marchant described several subspecies: Allen Lowrie restored or elevated to species rank to "D. purpurascens", "D. humilis", and "D. rupicola", respectively. In 1992, Lowrie and Marchant together described several more subspecies: Lowrie restored subsp. "porrecta" to "D. porrecta" and elevated subsp. "prostrata" to "D. prostrata" in 2005. When publishing the elevation of subspecies "monticola" to species rank, Lowrie did not include a correct page citation for the basionym, which under Article 33.4 of the International  Code of Botanical Nomenclature made the new combined name invalid. This was corrected in 2011 by Lowrie. That means that "D. stolonifera stolonifera" is now simply known as "D. stolonifera" with no subtaxa. Within the species, there are two morphs that Lowrie described in 2005, though not formally as a form. He identified a typical variant from the swamplands that grows in peaty, sandy soils in winter-wet heaths and a "hills variant" that grows in well-drained clayey sands in jarrah woodlands and becomes redder as the foliage ages.
