Stylidium edentatum
Stylidium edentatum is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae). It is an annual plant that grows around 6 cm tall. The elliptical leaves form a basal rosettes around the stem. The leaves are around 0.3-0.8 mm long with recurved margins. Inflorescences are produced on solitary scapes and bear flowers that are white with rose-coloured markings at the base of the corolla lobes and two tooth-shaped throat appendages present. "S. edentatum" was a previously overlooked species that is related to and appears similar to "S. calcaratum" and "S. ecorne". Allen Lowrie  and Sherwin Carlquist described this species in 1989 and argued that if "S. ecorne" is considered distinct from "S. calcaratum", then certainly "S. edentatum" warrants placement at the species level. It differs from "S. calcaratum" and "S. ecorne" by the long petioles on its recurved leaves, and the cuneate, obtuse, and unlobed posterior corolla lobes. They also have a distinctive lateral toothlike appendage at the base of each posterior corolla lobe. "S. edentatum" is endemic to southwestern Western Australia.
