Stylidium Sect. Tenella
''Stylidium'' rank (botany), section ''Tenella'' is a taxonomic rank in the plant kingdom under ''Stylidium'' subgenus ''Stylidium subg. Andersonia, Andersonia''. In 2000, A.R. Bean published a taxonomic revision of subgenus ''Andersonia'' and established this section to separate these eleven species based on morphological and cladistic analysis. This taxonomic rank is named after George Bentham's series (botany), series ''Tenellae'', which he established in his 1869 treatment of the family Stylidiaceae. Series ''Tenellae'' was not used in Johannes Mildbraed's 1908 taxonomic monograph in which he completely revised the subgeneric taxonomy of the genus. Mildbraed's treatment of the genus taxonomy is the general demarcation which has been used in subsequent revisions and additions.Bean, A.R. (2000). A revision of ''Stylidium'' subg.

Stylidium Fissilobum
''Stylidium fissilobum'' is a dicotyledonous plant that belongs to the genus ''Stylidium'' (family Stylidiaceae). It is an annual plant that grows from 5 to 50 cm tall. Linear or deltate leaves, about 4-34 per plant, are scattered along the elongate, glabrous stem. The leaves are generally 1–6 mm long and 0.3-0.7 mm wide. Petioles and scapes are absent. Inflorescences are 3–18 cm long. Flowers are pink, white, or mauve and bloom from March to July in the southern hemisphere. ''S. fissilobums wide distribution ranges across northern Australia from the western Kimberley region and Northern Territory eastward as far as Mount Surprise in Queensland. Its habitat is recorded as being wet sands at swamp edges in association with grasslands and sedgelands. Due to its weak stem, this species often threads its way through supporting branches and leaves of the dense grass and sedge cover. ''S. fissilobum'' is most closely related to '' S. aquaticum'' an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Series (botany)
In botany and plant taxonomy, a series is a subdivision of a genus, a taxonomic rank below that of section (and subsection) but above that of species. Sections and/or series are typically used to help organize very large genera Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclat ..., which may have hundreds of species.

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.

Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant families have varieties with rosette morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern '' Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plant. Function in flowering plants Often, rosettes form in perennial plants whose upper foliage dies back with the remaining vegetation protecting the plant. ...

Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of '' Euphorbia pulcherrima'' (poinsettia) and '' Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower brac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sessility (botany)
In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts (such as flowers and leaves) that have no stalk. Plant parts can also be described as subsessile, that is, not completely sessile. A sessile flower is one that lacks a pedicel (flower stalk). A flower that is not sessile is pedicellate. For example, the genus ''Trillium'' is partitioned into two subgenera, the sessile-flowered trilliums (''Trillium'' subg. ''Sessilium'') and the pedicellate-flowered trilliums. Sessile leaves lack petioles (leaf stalks). A leaf that is not sessile is petiolate. For example, the leaves of most monocotyledons lack petioles. The term sessility is also used in mycology to describe a fungal fruit body that is attached to or seated directly on the surface of the substrate Substrate may refer to: Physical layers *Substrate (biology), the natural environment in which an organism lives, or the surface or medium on whic ...

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 the family Stylidiaceae in 1908 as part of the unfinished '' Das Pflanzenreich'' series. The genus ''Mildbraediodendron ''Mildbraediodendron excelsum'' is a species of flowering plant in the family Fabaceae, and the only species in the genus ''Mildbraediodendron''. It belongs to the subfamily Faboideae. The genus was named in honor of the German botanist Johannes ...'' was named in honor of him.Quattrocchi, U. 1999.

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, ...

George Bentham
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884. Life Bentham was born in Stoke, Plymouth, on 22 September 1800.Jean-Jacques Amigo, « Bentham (George) », in Nouveau Dictionnaire de biographies roussillonnaises, vol. 3 Sciences de la Vie et de la Terre, Perpignan, Publications de l'olivier, 2017, 915 p.

Stylidium Subg
''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.
