Levenhookia Sect. Estipitatae
''Levenhookia'' sect. ''Estipitatae'' (sometimes spelled as ''Exstipitatae'') is a section of two to three recognized species in the family Stylidiaceae. It was established and described by Johannes Mildbraed in 1908 to separate the subgeneric taxonomy in the genus ''Levenhookia ''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 ...''. Mildbraed originally placed '' L. dubia'' and '' L. leptantha'' in this section. '' L. sonderi'' was described by Mildbraed as a variety of ''L. dubia'', though other resources treat it as a distinct species.Mildbraed, J. (1908). Stylidiaceae. In: Engler, A.

Levenhookia Dubia
''Levenhookia dubia'', the hairy stylewort, is a dicotyledonous plant that belongs to the genus ''Levenhookia'' (family Stylidiaceae). It is an ephemeral annual that grows from tall with obovate leaves that are generally long. Flowers are white and bloom from September to October in its native range. ''L. dubia'' is most closely related to '' L. sonderi'', which has been described as a variety of ''L. dubia'' in the past. It is endemic to Australia and has native ranges in Western Australia, South Australia, New South Wales, and Victoria. Its habitat has been reported as being sandy soils in granite outcrops.Paczkowska, Grazyna.

Levenhookia Leptantha
''Levenhookia leptantha'', the trumpet stylewort, is a dicotyledonous plant that belongs to the genus '' Levenhookia'' (family Stylidiaceae). It is an ephemeral annual that grows from tall with ovate to lanceolate leaves that are generally long. Flowers are pink and bloom from September to October in its native range. It is endemic to Western Australia. Its habitat has been reported as being sand or sandy clay soils in granite outcrops and winter-wet depressions.Paczkowska, Grazyna.

Levenhookia Sonderi
''Levenhookia sonderi'', the slender stylewort, is a dicotyledonous plant that belongs to the genus ''Levenhookia'' (family Stylidiaceae). It is an ephemeral annual that grows only in Victoria, Australia. ''L. sonderi'' is most closely related to '' L. dubia'' and it has even been described as a variety of ''L. dubia'' in the past. 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 ... was the first person to reduce ''L. sonderi'' to a variety of ''L. dubia'' in his 1908 taxonomic monograph on the Stylidiaceae in which he noted he could not find any significant difference between ''L. sonderi'' and ''L. dubia'' to maintain the separate taxonomic treatment of the two species. Later studies have considered the species to be distinct.Carlquist, S. (1969). Studies in ... [...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, ...

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.

Levenhookia
''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.Erickson, R. and Willis, J.H. (1966). Some additions to Australian Stylidiaceae. ''Victorian Naturalist'', 83: 107-112.Carlquist, S. (1969). Studies in Stylidiaceae: New taxa, field observations, evolutionary tendencies. ''Aliso'', 7(1): 13-64. All species of ''Levenhookia'' possess a sensitive labellum that performs a similar function to the column of ''Stylidium'' species. The labellum responds to touch and enables the plants to promote cross-pollination and avoid self-pollination. Most species of ''L ...
