Juncus Antarcticus
''Juncus antarcticus'', also known as dwarf rush, is a flowering plant species in the rush family Juncaceae, native to New Zealand and Australia. Description It is a dwarf perennial that forms cushions and has well-developed rhizomes and stolons. The culms are erect, smooth, and 0.5–5 cm high, both slightly shorter and slightly exceeding the leaves in length. The leaves are borne on the more or less elongated aerial portion of a stem, with the older leaves persisting and turning yellow-brown. The inflorescence is a 1–5-flowered cluster, which expands to about 3–7 mm in diameter when in fruit. There are three stamens, sometimes six. The upper part of the ovoid capsules is reddish-brown, and they are 2–3 mm long. Distribution In Australia, it is found in New South Wales, Tasmania, and Victoria. In Victoria, it is found late-lying snowpatches and at the edges of bogs and creeks on the Bogong High Plains. In New Zealand, it is found in both the North and South Islands ...

Walter Hood Fitch
Walter Hood Fitch (28 February 1817 – 1892) was a botanical illustrator, born in Glasgow, Scotland, who executed some 10,000 drawings for various publications. His work in colour lithograph, including 2700 illustrations for ''Curtis's Botanical Magazine'', produced up to 200 plates per year. Biography Fitch was involved in fabric printing from the age of 17 and took to botanical art after meeting William Jackson Hooker, Regius Professor of Botany, a competent botanical illustrator, and the editor of ''Curtis's Botanical Magazine''. Fitch's first lithograph of ''Mimulus roseus'' appeared in the Botanical Magazine in 1834, and he soon became its sole artist. In 1841 W.J. Hooker became director of Royal Botanic Gardens, Kew and Fitch moved to London. After 1841 Fitch was the sole artist for all official and unofficial publications issued by Kew; his work was paid for by Hooker personally. It was not unusual for him to work on several different publications simultaneously; he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campbell Islands
The Campbell Islands (or Campbell Island Group) are a group of subantarctic islands, belonging to New Zealand. They lie about 600 km south of Stewart Island. The islands have a total area of , consisting of one big island, Campbell Island (), and several small islets, notably Dent Island (), Isle de Jeanette Marie (), Folly Island (or Folly Islands), Jacquemart Island (), and Monowai Island (also known as Lion Rock, ). Ecologically, they are part of the Antipodes Subantarctic Islands tundra ecoregion. The islands are one of five subantarctic island groups collectively designated as a World Heritage Site by UNESCO. Geography * Campbell Island / Motu Ihupuku () * Dent Island () * Jacquemart Island () * Folly Island or Folly Islands The islands are relatively flat; due to tectonic pressure, however, there are mountains in the centre of each island. A sea stack at the southern tip of Jacquemart Island is – with the exception of the country's Antarctic claims – New Z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Joseph Dalton Hooker
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1844
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juncus
''Juncus'' is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species. Description Rushes of the genus ''Juncus'' are herbaceous plants that superficially resemble grasses or sedges. They have historically received little attention from botanists; in his 1819 monograph, James Ebenezer Bicheno described the genus as "obscure and uninviting". The form of the flower differentiates rushes from grasses or sedges. The flowers of ''Juncus'' comprise five whorls of floral parts: three sepals, three petals (or, taken together, six tepals), two to six stamens (in two whorls) and a stigma with three lobes. The stems are round in cross-section, unlike those of sedges, which are typically somewhat triangular in cross-section. In ''Juncus'' section ''Juncotypus'' (formerly called ''Juncus'' subg. ''Genuini''), which contains some of the most widespread and familiar species, the leaves are reduced t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...

Flora And Fauna Guarantee Act 1988
The ''Flora and Fauna Guarantee Act 1988'', also known as the ''FFG Act'', is an act of the Victorian Government designed to protect species, genetic material and habitats, to prevent extinction and allow maximum genetic diversity within the Australian state of Victorian for perpetuity. It was the first Australian legislation to deal with such issues. It enables the listing of threatened species and communities and threats to native species, and the declaration of critical habitat necessary for the survival of native plants and animals. After an extensive review of the Act in 2019, the ''Flora and Fauna Guarantee Amendment Act 2019'' modernised and strengthened the provisions of the Act on 1 June 2020. Enforcement of the ''FFG Act'' is overseen by the Office of the Conservation Regulator (OCR). Description The ''Flora and Fauna Guarantee Act 1988'' helps to protect and manage the biodiversity of the state of Victoria. It aims to conserve all of Victoria’s native plants and a ...

New Zealand Threat Classification System
The New Zealand Threat Classification System is used by the Department of Conservation to assess conservation priorities of species in New Zealand. The system was developed because the IUCN Red List, a similar conservation status system, had some shortcomings for the unique requirements of conservation ranking in New Zealand. plants, animals, and fungi are evaluated, though the lattermost has yet to be published. Algae were assessed in 2005 but not reassessed since. Other protists have not been evaluated. Categories Species that are ranked are assigned categories: ;Threatened This category has three major divisions: ::*Nationally Critical - equivalent to the IUCN category of Critically endangered ::*Nationally Endangered - equivalent to the IUCN category of Endangered ::*Nationally Vulnerable - equivalent to the IUCN category of Vulnerable ;At Risk This has four categories: ::*Declining ::*Recovering ::*Relict ::*Naturally Uncommon ;Other categories ;;Introduced and Natur ...
