Rhytidosporum
''Rhytidosporum'' is a genus of flowering plants within the family Pittosporaceae. The type species is ''Rhytidosporum procumbens'' (Hook.) F.Muell. Description ''Rhytidosporum'' species are generally small herbs, or low shrubs, with alternate leaves which are often toothed at the apex. The flowers are small, generally solitary, and occur both in the axils and terminally. The five equal petals are white often tinged with red. The anthers shed their pollen longitudinally. The capsule is stalkless, with generally two locules. The seeds are dry, wrinkled and wingless.

Rhytidosporum Procumbens
Summary ''Rhytidosporum procumbens'', commonly referred to as White Marianth, is a member of the family Pittosporaceae. The dwarf, perennial shrub is characterised by single or small groups of 2-3 white flowers measuring 15mm in diameter present in upper leaf axils during August-December. The 5-20mm leaves are narrow in shape with pointed or 3-toothed tips and margins curved under. ''R. procumbens'' is an Australian native and endemic that is locally common within its preferred growing conditions but has an otherwise limited distribution. Thus, it is generally restricted to New South Wales, Victoria, and Tasmania. In 1836, the species was first formally described by William Jackson Hooker, an English botanist. The species was later transferred from its original genus, '' Pittosporum,'' into '' Rhytidosporum'', which was first described in 1862 by Ferdinand von Mueller, a Victorian Government Botanist.

Rhytidosporum Inconspicuum
''Rhytidosporum inconspicuum'' (common name alpine appleberry) is an inconspicuous, rhizomatous shrub in the pittosporum family, Pittosporaceae. The species is found in New South Wales, Victoria and Tasmania. The species was first formally described in 1999 by Lindy Cayzer, Michael Crisp and Ian Telford, when they published a revision of the genus, '' Rhytidosporum''. The species epithet, ''inconspicuum'', was given because the plant is inconspicuous when not in flower or fruit. Conservation status It has been declared an "endangered species" under the Tasmanian Threatened Species Protection Act 1995 The ''Threatened Species Protection Act 1995'' (TSP Act), is an act of the Parliament of Tasmania that provides the statute relating to conservation of flora and fauna. Its long title is An Act to provide for the protection and management of th ... but has not been listed under the Commonwealth EPBC Act.

Pittosporaceae
Pittosporaceae is a family of flowering plants that consists of 200–240 species of trees, shrubs, and lianas in 9 genera. Habitats range from tropical to temperate climates of the Afrotropical, Indomalayan, Oceanian, and Australasian realms. The type genus is ''Pittosporum'' Banks ex Gaertn. Description Pittosporaceae are dioecious trees, shrubs, or twining vines, with leaves having pinnate venation, no stipules, and margins that are smooth. Ovaries are superior, often with parietal placentation. The style is undivided and straight, and the stigma is often lobed. The fruit is a capsule or berry with the calyx being shed from the fruit. The seeds are surrounded by sticky pulp that comes from secretions of the placental hairs. The flowers have equal numbers of sepals, petals and stamens.Stevens, P.F.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hook
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved or indented, such that it can be used to grab onto, connect, or otherwise attach itself onto another object. In a number of uses, one end of the hook is pointed, so that this end can pierce another material, which is then held by the curved or indented portion. Some kinds of hooks, particularly fish hooks, also have a barb, a backwards-pointed projection near the pointed end of the hook to ensure that once the hook is embedded in its target, it can not easily be removed. Variations * Bagging hook, a large sickle or reaping hook used for harvesting grain * Bondage hook, used in sexual bondage play * Cabin hook, a hooked bar that engages into an eye screw, used on doors * Cap hook, hat ornament of the 15th and 16th centuries * Cargo hook (helicopter), different types of hook systems for helicopters * Crochet hook, used for crocheting thread or yarn * Drapery hook, for ha ...

Australian Plant Name Index
The Australian Plant Name Index (APNI) is an online database of all published names of Australian vascular plants. It covers all names, whether current names, synonyms or invalid names. It includes bibliographic and typification details, information from the Australian Plant Census including distribution by state, links to other resources such as specimen collection maps and plant photographs, and the facility for notes and comments on other aspects. History Originally the brainchild of Nancy Tyson Burbidge, it began as a four-volume printed work consisting of 3,055 pages, and containing over 60,000 plant names. Compiled by Arthur Chapman, it was part of the Australian Biological Resources Study (ABRS). In 1991 it was made available as an online database, and handed over to the Australian National Botanic Gardens. Two years later, responsibility for its maintenance was given to the newly formed Centre for Plant Biodiversity Research. Scope Recognised by Australian herbaria as the ...

Apiales Of Australia
The Apiales are an order of flowering plants. The families are those recognized in the APG III system. This is typical of the newer classifications, though there is some slight variation and in particular, the Torriceliaceae may also be divided. Under this definition, well-known members include carrots, celery, parsley, and ''Hedera helix'' (English ivy). The order Apiales is placed within the asterid group of eudicots as circumscribed by the APG III system. Within the asterids, Apiales belongs to an unranked group called the campanulids, and within the campanulids, it belongs to a clade known in phylogenetic nomenclature as Apiidae. In 2010, a subclade of Apiidae named Dipsapiidae was defined to consist of the three orders: Apiales, Paracryphiales, and Dipsacales. Taxonomy Under the Cronquist system, only the Apiaceae and Araliaceae were included here, and the restricted order was placed among the rosids rather than the asterids. The Pittosporaceae were placed within the R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
