Stylidium Sect. Alsinoida
''Stylidium'' section ''Alsinoida'' is a taxonomic rank under ''Stylidium'' subgenus '' Andersonia''. In his 1908 monograph on the family Stylidiaceae, Johannes Mildbraed Gottfried Wilhelm Johannes Mildbraed (19 December 1879 – 24 December 1954) was a German botanist that specialized in mosses, ferns, and various spermatophytes. He is well known for authoring the most current monograph and taxonomic treatment of ... had established the subgenus ''Alsinoides'' for species related to '' S. alsinoides'', which were morphologically similar to species of subgenus ''Andersonia''. In 2000, A.R. Bean published a taxonomic revision of subgenus ''Andersonia'' and reduced subgenus ''Alsinoides'' to sectional rank, renamed ''Alsinoida''.Bean, A.R. (2000).

Stylidium Alsinoides
''Stylidium alsinoides'' is a dicotyledonous plant that belongs to the genus '' Stylidium'' (family Stylidiaceae). It is an erect annual plant that grows from tall. Obovate or elliptical leaves, about 20–100 per plant, are scattered along the elongate, glabrous stems. The leaves are generally long and wide. The bracts on the inflorescence can be as large as leaves and may be hard to distinguish them except for their growth habit: the leaves are alternate whereas the bracts are opposite.Bean, A.R. (2000). A revision of ''Stylidium'' subg. ''Andersonia'' (R.Br. ex G.Don) Mildbr. (Stylidiaceae). ''Austrobaileya'' 5(4): 589-649. This species lacks a scape. Inflorescences are long and produce white flowers that bloom from April to September in Australia but occur year-round in Malesia. ''S. alsinoidess distribution ranges from northern Queensland in Australia north to the island of Luzon in the Philippines and southern parts of Sulawesi in New Guinea. In Australia its ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stylidium
''Stylidium'' (also known as 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rank (botany)
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.

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, ...
