Drosera marchantii is an erect perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to Western Australia and grows in a variety of habitats, including swampy areas and hilltops in laterite-silica sand soils. D. marchantii produces small, circular, peltate carnivorous leaves along stiff stems that can be 10–40 cm (4–16 in) high. Its pink flowers emerge from June to October.[1][2][3]

Drosera marchantii was first described and named by Larry Eugene DeBuhr in 1975. In 1992, N. G. Marchant and Allen Lowrie published the formal description of D. marchantii subsp. prophylla, a subspecies that is distinguished by its white flowers, smaller height, and numerous bracts (prophylls) on the lower part of the stem. It has only been found in a small area north of Perth and is listed by Western Australia's Department of Environment and Conservation as a priority three poorly known taxon on the Declared Rare and Priority Flora List.[4][5]
