Stylidium perplexum

S. perplexum was first collected by Graham S. McCutcheon in 1983, but was initially identified as S. fasciculatum. Juliet Wege discovered the specimen at the Western Australian Herbarium (PERTH) and then relocated McCutcheon's original collection site in November 2007. The only known location of this species is on the Whicher Scarp, near Dardanup. It grows in lateritic soils among Eucalyptus marginata and Corymbia haematoxylon woodlands. It flowers in November and December.[1]

Wege published the formal description of this species in August 2008.[1][2]
