Achyranthes Margaretarum
''Achyranthes margaretarum'' is a species of plant belonging to the family Amaranthaceae. It is endemic to Phillip Island, close to Norfolk Island in the south west Pacific Ocean, where it was discovered during the 1980s after rabbits had been eradicated from the island. This provides dramatic evidence of the value of the eradication program. It is considered critically endangered due to its very small population size - fewer than 20 mature individuals were known, in a single location on Phillip Island, in 2003. In 2009 Mills identified 22 plants on Phillip Island, including planted specimens, only nine higher than 50 cm. This plant is similar to ''Achyranthes arborescens'', an endemic from neighbouring Norfolk Island, but is a smaller, more compact shrub growing up to 2m tall with a 2m spread. ''A. margaretarum'' also differs in having small, rather fleshy, bronze-green leaves with yellow veins; small, erect inflorescences carrying just a few maroon-coloured flowers; and s ...

Plant
Plants are predominantly photosynthetic eukaryotes of the 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 Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and 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 color. Some plants are parasitic or mycotrophic and have lost the ...

Amaranthaceae
Amaranthaceae is a family of flowering plants commonly known as the amaranth family, in reference to its type genus ''Amaranthus''. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales. Description Vegetative characters Most species in the Amaranthaceae are annual or perennial herbs or subshrubs; others are shrubs; very few species are vines or trees. Some species are succulent. Many species have stems with thickened nodes. The wood of the perennial stem has a typical "anomalous" secondary growth; only in subfamily Polycnemoideae is secondary growth normal. The leaves are simple and mostly alternate, sometimes opposite. They never possess stipules. They are flat or terete, and their shape is extremely variable, with entire or toothed margins. In some species, the leaves are reduced to minute scales. In most cases, neither basal nor terminal aggrega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phillip Island (Norfolk Island)
Phillip Island is an island located south of Norfolk Island in the Southwest Pacific, and is part of the Norfolk Island group. It was named in 1788 by Lieutenant Philip Gidley King after Arthur Phillip, the first Governor of New South Wales. Phillip Island is part of the Australian external territory of Norfolk Island, and is included in Norfolk Island National Park, as is neighbouring Nepean Island and about 10 percent of Norfolk Island proper. A National Parks hut located near the centre of the island houses a small rotating group of around four people for much of the year. Otherwise the island is uninhabited. Phillip Island has an area of , measuring from west to east and from north to south, with the highest point, Jacky Jacky, being above sea level. It is roughly shaped like a hairdryer with the nozzle pointing east. The island is of volcanic origin, made of basaltic tuff and lava dating from the Miocene epoch. Phillip Island is included on the Register of the N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norfolk Island
Norfolk Island (, ; Norfuk: ''Norf'k Ailen'') is an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia, directly east of Australia's Evans Head and about from Lord Howe Island. Together with the neighbouring Phillip Island and Nepean Island, the three islands collectively form the Territory of Norfolk Island. At the 2021 census, it had inhabitants living on a total area of about . Its capital is Kingston. The first known settlers in Norfolk Island were East Polynesians but they had already departed when Great Britain settled it as part of its 1788 settlement of Australia. The island served as a convict penal settlement from 6 March 1788 until 5 May 1855, except for an 11-year hiatus between 15 February 1814 and 6 June 1825, when it lay abandoned. On 8 June 1856, permanent civilian residence on the island began when descendants of the ''Bounty'' mutineers were relocated from Pitcairn Island. In 1914 the UK handed Norfo ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Achyranthes Arborescens
''Achyranthes arborescens'' (common names - Chaff tree, Soft-wood) is a plant in the Amaranthaceae family endemic to Norfolk Island. It is a critically endangered species under the Australian Federal government's Environment Protection and Biodiversity Conservation Act. Description ''A. arborescens'' is a soft-wooded tree growing up to a height of 9 m. Its leaves are on slender stalks which are 5–15 mm long and have hairs lying close to them (appressed hairs). The leaf blades are elliptic to slightly oblanceolate, and from 50 to 80 mm long (sometimes 30–100 mm long) by 20–35 mm broad (with the juvenile foliage being larger). The base of the blade is acute and attenuates to the stalk. The leaf margins have irregular and very shallowly rounded teeth, and are yellow-green or dark green above, and light green below. The margins are very minutely fringed, and there are appressed hairs on the midrib beneath. The inflorescence is a spike and is terminal on ...

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaves
A leaf (plural, : leaves) is any of the principal appendages of a vascular plant plant stem, stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthesis, photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...
