Stylidium arenicola is a species of dicotyledon plant in the genus Stylidium (also known as trigger plants). It was described in 1969 by Sherwin Carlquist. [1] [2]
The species is endemic to Western Australia, where it is mostly found in Wiluna and in Kalgoorlie. [3]
Stylidium is a genus of dicotyledonous plants that belong to the family Stylidiaceae. The genus name Stylidium is derived from the Greek στύλος or stylos, which refers to the distinctive reproductive structure that its flowers possess. Pollination is achieved through the use of the sensitive "trigger", which comprises the male and female reproductive organs fused into a floral column that snaps forward quickly in response to touch, harmlessly covering the insect in pollen. Most of the approximately 300 species are only found in Australia, making it the fifth largest genus in that country. Triggerplants are considered to be protocarnivorous or carnivorous because the glandular trichomes that cover the scape and flower can trap, kill, and digest small insects with protease enzymes produced by the plant. Recent research has raised questions as to the status of protocarnivory within Stylidium.

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. Robert Brown had described this species in 1810 under the name S. tenellum, a name which had already been used for another species in 1805 by Olof Swartz. 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.
Stylidium fimbriatum is a dicotyledonous plant that belongs to the genus Stylidium. It is an erect annual plant that grows from 15 to 30 cm tall. Oblanceolate leaves, about 16 per plant, form a basal rosette around the compressed stems. The leaves are generally 5–20 mm long and 2–7 mm wide. This species generally has one or two scapes and cymose inflorescences that are 15–30 cm long. Flowers are pink with yellow highlights. S. fimbriatum's distribution is confined to the area around Bachsten Creek in the Kimberley region in Western Australia. Its typical habitat is herbfields that are seasonally wet.
Stylidium prophyllum is a dicotyledonous plant that belongs to the genus Stylidium. It is an annual plant that grows from 8 to 30 cm tall. The deltate leaves, about 4-10 per plant, are scattered along the elongate, glabrous stem and are generally 0.7-1.5 mm long and 0.3-0.6 mm wide. Petioles and scapes are absent. Inflorescences are 3–14 cm long and produce pink flowers that bloom from February to June in the southern hemisphere. S. prophyllum is endemic to the area in and around the Kimberley region in Western Australia. Its habitat is recorded as being "grassy floodplains, seepage areas, and waterways." S. prophyllum is most closely related to S. fissilobum but differs mostly in its glabrous sepals.
Stylidium perizostera is a dicotyledonous plant that belongs to the genus Stylidium. It is an annual plant that grows from 5 to 11 cm tall. The linear leaves, about 8–12 per plant, are mostly in terminal rosettes but with some scattered along the elongate, glabrous stem. The leaves are around 7.5 mm long and 0.4-0.7 mm wide. Petioles are absent. This species produces 1-10 scapes per plant. Inflorescences are around 9 cm long and produce a single white, yellow, and orange flower. S. perizostera is endemic to the Kimberley region in Western Australia and ranges from the Mitchell Plateau to Bigge Island. Its habitat is recorded as being near sandstone outcrops in drainage lines.
Levenhookia, also known as the styleworts, is a genus of ten recognized species in the family Stylidiaceae and is endemic to Australia. The genus is restricted to Western Australia almost exclusively with a few exceptions: L. pusilla's range extends into South Australia, L. dubia's range extends through South Australia into Victoria and New South Wales, L. sonderi is native only to Victoria, and L. chippendalei is also found in the Northern Territory.
Stylidium perpusillum, the tiny triggerplant, is a dicotyledonous plant that belongs to the genus Stylidium, that occurs in south west Western Australia.
Stylidium rupestre is a dicotyledonous plant that belongs to the genus Stylidium, a species sometimes named as the rock triggerplant. It is found in Southwest Australia. The species was first described by Otto Wilhelm Sonder.
Stylidium spathulatum is a dicotyledonous plant that belongs to the genus Stylidium. The species is informally named the creamy triggerplant for the colour of its flowers.
Stylidium affine is a species in the genus Stylidium that is endemic to Western Australia.
Stylidium humphreysii is a species of trigger plant endemic to desert regions of Western Australia. American botanist Sherwin Carlquist named the species after West Australian amateur botanist Fred Humphreys.
Stylidium divaricatum, known by the vernacular name daddy-long-legs, is a species in the genus Stylidium that is endemic to Western Australia.
Stylidium exappendiculatum is a species of dicotyledonous plant in the genus Stylidium.
Stylidium squamosotuberosum is a species of plant in the genus Stylidium. It was described in 1969 by Sherwin Carlquist. Discovered in 1969.
Stylidium piliferum is a species of dicotyledonous plant from the genus Stylidium. It is found in Western Australia.
Stylidium schoenoides is a species of dicotyledon plant of the Stylidium genus, from Stylidiaceae family, Asterales order, first described by Augustin Pyramus de Candolle in 1839. The plant is endemic to Western Australia.
