Stylidiaceae
The family Stylidiaceae is a taxon of dicotyledonous flowering plants. It consists of five genera with over 240 species, most of which are endemic to Australia and New Zealand. Members of Stylidiaceae are typically grass-like herbs or small shrubs and can be perennials or annuals. Most species are free standing or self-supporting, though a few can be climbing or scrambling (''Stylidium scandens'' uses leaf tips recurved into hooks to climb). The pollination mechanisms of ''Stylidium'' and '' Levenhookia'' are as follows: In ''Stylidium'' the floral column, which consists of the fused stamen and style, springs violently from one side (usually under the flower) when triggered. This deposits the pollen on a visiting insect. In ''Levenhookia'', however, the column is immobile, but the hooded labellum is triggered and sheds pollen. In 1981, only about 155 species were known in the family. The current number of species by genus (reported in 2002) is as follows: ''Forstera'' - 5, ''L ...

Donatioideae
''Donatia'' is a genus of two cushion plant species in the family Stylidiaceae. The name commemorates Vitaliano Donati, an Italian botanist. ''Donatia'' has been placed in the subfamily Donatioideae, described by Johannes Mildbraed in his 1908 taxonomic monograph of the family Stylidiaceae. The subfamily was created to distinguish the difference between the single genus ''Donatia'' from the five typical genus, genera of the Stylidiaceae that Mildbraed placed in the Stylidioideae subfamily.Mildbraed, J. (1908). Stylidiaceae. ''In'' Engler, A. ''Das Pflanzenreich: Regni vegetabilis conspectus'', IV. 278. Leipzig, 1908. The subfamily taxonomy represented the taxonomic uncertainty of ''Donatia'', which had at one point also been placed in the Saxifragaceae.Wagstaff, S.J. and Wege, J.

Oreostylidium
''Oreostylidium'' is a genus of flowering plants in the family Stylidiaceae with a single species, ''Oreostylidium subulatum'', that is endemic to New Zealand. ''O. subulatum'' is a very small plant with small, white flowers. It has a complicated botanical history that has led to a few proposals to move ''Oreostylidium'' to the related genus ''Stylidium''. The researchers cite molecular data and suspect that this species is an extreme example of floral paedomorphosis. This would not be an unprecedented move since the single species was initially described as ''Stylidium subulatum'' in 1864 and later moved to its own genus by Sven Berggren in 1878. It possesses the same kind of glandular trichomes underneath the flower that make ''Stylidium'' species carnivorous plants, but it has not yet been tested for the presence of digestive enzymes. Characteristics ''Oreostylidium subulatum'' is a very small, cæspitose, and densely tufted plant about 2–3 cm tall. The 2 cm lon ...

Stylidium Amoenum
''Stylidium'' (the triggerplants or trigger plants) is a genus of dicotyledonous plants that belong to the family Stylidiaceae. The genus name ''Stylidium'' is derived from the Greek ''στύλος'' or ''stylos'' (column or pillar), 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.'' Charac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Levenhookia
''Levenhookia'', also known as the styleworts, is a genus of ten recognized species in the family Stylidiaceae and is endemism, endemic to Australia. The genus is restricted to Western Australia almost exclusively with a few exceptions: ''Levenhookia pusilla, L. pusilla'''s range extends into South Australia, ''Levenhookia dubia, L. dubia'''s range extends through South Australia into Victoria (Australia), Victoria and New South Wales, ''Levenhookia sonderi, L. sonderi'' is native only to Victoria, and ''Levenhookia chippendalei, L. chippendalei'' is also found in the Northern Territory.Erickson, R. and Willis, J.H.
