Stylidium candelabrum is a dicotyledonous plant that belongs to the genus Stylidium. It is an erect annual plant that grows from 6 to 20 cm tall. Elliptical leaves, about 11-100 per plant, are scattered along the stem. The leaves are generally 2.5–18 mm long and 1.5–9 mm wide. This species generally has 1-13 scapes and cymose inflorescences that are 3–16 cm long. Flowers are white. S. candelabrum is endemic to the northernmost area of the Northern Territory in Australia and much of its range is within a national park and therefore has been evaluated to be neither rare nor threatened. Its typical habitat is shallow sand associated with sandstone pavements and it appears to prefer areas with higher rainfall. It flowers in the southern hemisphere from March to July. Its conservation status has been assessed as secure.
Stylidium divergens is a dicotyledonous plant that belongs to the genus Stylidium and was described as a new species in 2000.

Stylidium ensatum is a dicotyledonous plant that belongs to the genus Stylidium that was described as a new species by A.R. Bean in 2000, though the taxon had been noted by Rica Erickson in her discussion of S. muscicola variation in 1958. The specific epithet ensatum is from the Latin ensatus, meaning sword-like, which refers to the shape of the floral throat appendages of this species.

S. schizanthum is closely related to both S. pachyrrhizum and S. lobuliflorum.
Stylidium stenophyllum is a dicotyledonous plant that belongs to the genus Stylidium that was described by A.R. Bean in 2000. It is an erect annual plant that grows from 30 to 40 cm tall. Linear leaves, about 7-25 per plant, are scattered along the stems. The leaves are generally 36–86 mm long and 1.5-2.5 mm wide. This species generally has three to four scapes and cymose inflorescences that are 28–39 cm long. Flowers are white or pink. S. stenophyllum is endemic to the far northeastern Northern Territory of Australia and is only known from the type location. It has only been recorded from one sandstone monolith known as a beehive formation where less than 100 clumps of plants survive at the concentration of about 10 individual plants per clump. For this reason, A.R. Bean suggested a vulnerable conservation status. However it currently appears on neither the IUCN Red List nor the EPBC Act list of threatened flora.
Stylidium tenerum, the swamp triggerplant, is a dicotyledonous plant that belongs to the genus Stylidium that was described by Curt Polycarp Joachim Sprengel in 1826.

To add to the confusion, Rica Erickson had described and illustrated this taxon in 1958 under the name S. uliginosum, another currently accepted name for a related species.
