Stylidium Sect. Uniflora
''Stylidium'' section ''Uniflora'' is a taxonomic rank under ''Stylidium'' subgenus '' Andersonia''. In 2000, A.R. Bean published a taxonomic revision of subgenus ''Andersonia'' and established this section to separate these five species based on morphological and cladistic analysis.Bean, A.R. (2000). A revision of ''Stylidium'' subg. ''Andersonia'' (R.Br. ex G.Don) Mildbr. (Stylidiaceae). ''Austrobaileya'' 5(4): 589-649. As the section epithet suggests, the most striking feature of the species in this taxonomic group are the solitary flowers on the scapes, a departure from the traditional form of most ''Stylidium'' species which have more than one flower per scape. Distribution is primarily in tropical Australia with one species, '' S. pedunculatum'' also being found on the Aru Islands The Aru Islands Regency ( id, Kabupaten Kepulauan Aru) is a group of about 95 low-lying islands in the Maluku Islands of eastern Indonesia. It also forms a regency of Maluku Province, with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister i ...

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.

Cladistics
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a ' grade', which are fruitless to precisely delineate, especially when including extinct species. ...

Epithet
An epithet (, ), also byname, is a descriptive term (word or phrase) known for accompanying or occurring in place of a name and having entered common usage. It has various shades of meaning when applied to seemingly real or fictitious people, divinities, objects, and binomial nomenclature. It can also be a descriptive title: for example, Pallas Athena, Phoebus Apollo, Alfred the Great, Suleiman the Magnificent, and Władysław I the Elbow-high. Many English monarchs have traditional epithets: some of the best known are Edward the Confessor, William the Conqueror, Richard the Lionheart, Æthelred the Unready, John Lackland and Bloody Mary. The word ''epithet'' can also refer to an abusive, defamatory, or derogatory phrase. This use as a euphemism is criticized by Martin Manser and other proponents of linguistic prescription. H. W. Fowler complained that "epithet is suffering a vulgarization that is giving it an abusive imputation." Linguistics Epithets are somet ...

Scape (botany)
In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafless flowering stem rising directly from a bulb, rhizome, or similar subterranean or underwater structure. The scapes of scallions, chives, garlic chives, and garlic are used as vegetables. Etymology and usages The word ''scape'' (Latin ''scapus'', from Greek σκᾶπος), as used in botany, is fairly vague and arbitrary; various sources provide divergent definitions. Some older usages simply amount to a stem or stalk in general, but modern formal usage tends to favour the likes of "A long flower stalk rising directly from the root or rhizome", or "a long, naked, or nearly naked, peduncle, rising direct from the base of a plant, whether 1- or many-fid."Chittenden, Fred J.
