Myosotis Rakiura
''Myosotis rakiura'' is a species of flowering plant in the family Boraginaceae, endemic to southern South Island and Stewart Island/Rakiura of New Zealand. Joseph Beattie Armstrong described the species in 1881. Plants of this species of forget-me-not are perennial rosettes which form loose tufts or clumps, with ebracteate, erect inflorescences, and white corollas with exserted stamens. Taxonomy and etymology ''Myosotis rakiura'' is in the plant family Boraginaceae and was described as ''M. capitata'' var. ''albiflora'' in 1881 by Joseph Beattie Armstrong . Lucy Moore gave it a new name, ''M. rakiura,'' when she recognized it at the species level, because '' M. albiflora'' Banks & Sol. ex Hook.f. was already validly published for a southern South American species. ''Myosotis rakiura'' is morphologically similar to other ebracteate-erect species, especially the New Zealand subantarctic island endemic species, '' M. capitata''. ''Myosotis rakiura'' can be distinguished ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lucy Moore (botanist)
Lucy Beatrice Moore (14 July 1906 – 9 June 1987) was a New Zealand botanist and ecologist.

Ngāi Tahu
Ngāi Tahu, or Kāi Tahu, is the principal Māori (tribe) of the South Island. Its (tribal area) is the largest in New Zealand, and extends from the White Bluffs / Te Parinui o Whiti (southeast of Blenheim), Mount Mahanga and Kahurangi Point in the north to Stewart Island / Rakiura in the south. The comprises 18 (governance areas) corresponding to traditional settlements. Ngāi Tahu originated in the Gisborne District of the North Island, along with Ngāti Porou and Ngāti Kahungunu, who all intermarried amongst the local Ngāti Ira. Over time, all but Ngāti Porou would migrate away from the district. Several were already occupying the South Island prior to Ngāi Tahu's arrival, with Kāti Māmoe only having arrived about a century earlier from the Hastings District, and already having conquered Waitaha, who themselves were a collection of ancient groups. Other that Ngāi Tahu encountered while migrating through the South Island were Ngāi Tara, Rangitāne, Ngāti T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hautere
The Solander Islands / Hautere are three uninhabited volcanic islets toward the western end of the Foveaux Strait just beyond New Zealand's South Island. The Māori name ''Hautere'' translates into English as "flying wind". The islands lie south of Prices Point, near where Lake Hakapoua drains through Big River to the ocean due west of Te Waewae Bay, and northwest of the Putatara (Rugged) Point in the northwest of Stewart Island / Rakiura, or from Codfish Island / Whenua Hou. The islands measure . Administratively, the islands form part of Southland District, making them the only uninhabited outlying island group of New Zealand to be part of a local authority. The islands are the tip of a larger submerged volcano, roughly equivalent in size to Mount Taranaki. It was formerly believed that the volcano last erupted roughly 2 million years ago, but in 2010 radiometric dating of rock samples from the island found that it was between 150,000 and 400,000 years old.

Southland District
Southland District is a Districts of New Zealand, territorial authority district in New Zealand that covers the south of the South Island as well as Stewart Island, Stewart Island/Rakiura. History Southland District was formed through the 1989 local government reforms. Four local authorities were amalgamated at that time: Wallace County, New Zealand, Wallace County, Winton, New Zealand, Winton Borough, Stewart Island County and most of Southland County. John Casey, who was first elected onto Southland County Council in 1977, oversaw the amalgamation and was elected Southland District's first Mayor of Southland, mayor in 1989. Winton Wallacetown Ward was renamed Oreti Ward with effect from the Council election on 12 October 2019. The Oreti River flows through this ward. Geography Southland District covers the majority of the land area of Southland, New Zealand, Southland Region, although the region also covers Gore, New Zealand, Gore District, Invercargill, Invercargill City and ...

Otago
Otago (, ; mi, Ōtākou ) is a region of New Zealand located in the southern half of the South Island administered by the Otago Regional Council. It has an area of approximately , making it the country's second largest local government region. Its population was The name "Otago" is the local southern Māori dialect pronunciation of "Ōtākou", the name of the Māori village near the entrance to Otago Harbour. The exact meaning of the term is disputed, with common translations being "isolated village" and "place of red earth", the latter referring to the reddish-ochre clay which is common in the area around Dunedin. "Otago" is also the old name of the European settlement on the harbour, established by the Weller Brothers in 1831, which lies close to Otakou. The upper harbour later became the focus of the Otago Association, an offshoot of the Free Church of Scotland, notable for its adoption of the principle that ordinary people, not the landowner, should choose the ministe ...

Forget-me-not
''Myosotis'' ( ) is a genus of flowering plants in the family Boraginaceae. The name comes from the Ancient Greek "mouse's ear", which the foliage is thought to resemble. In the northern hemisphere they are colloquially known as forget-me-nots or scorpion grasses. ''Myosotis alpestris'' is the official flower of Alaska and Dalsland, Sweden. Plants of the genus are commonly confused with Chatham Islands' forget-me-nots, which belong to the related genus '' Myosotidium''. Description The genus was originally described by Carl Linnaeus. The type species is ''Myosotis scorpioides''. ''Myosotis'' species are annual or perennial herbaceous flowering plants with penta merous actinomorphic flowers with 5 sepals and petals. Flowers are typically 1 cm in diameter or less, flatly faced, coloured blue, pink, white or yellow with yellow centres and borne on scorpioid cymes. The foliage is alternate, and their roots are generally diffuse. They typically flower in spring or soon after ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts. In cultivation In Halloween types of pumpkin or squash plants, the shape of the pedicel has received particular attention because plant breeders are trying to optimize the size and shape of the pedicel for the best "lid" for a "jack-o'-lantern".

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 ...

Obtuse (leaf)
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses (Poaceae), ...

Chloroplast DNA
Chloroplast DNA (cpDNA) is the DNA located in chloroplasts, which are photosynthetic organelles located within the cells of some eukaryotic organisms. Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA was identified biochemically in 1959, and confirmed by electron microscopy in 1962. The discoveries that the chloroplast contains ribosomes and performs protein synthesis revealed that the chloroplast is genetically semi-autonomous. The first complete chloroplast genome sequences were published in 1986, ''Nicotiana tabacum'' (tobacco) by Sugiura and colleagues and ''Marchantia polymorpha'' (liverwort) by Ozeki et al. Since then, a great number of chloroplast DNAs from various species have been sequenced. Molecular structure Chloroplast DNAs are circular, and are typically 120,000–170,000 base pairs long. They can have a contour length of around 30–60 micrometers, and have a mass of about 80 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ribosomal DNA
Ribosomal DNA (rDNA) is a DNA sequence that codes for ribosomal RNA. These sequences regulate transcription initiation and amplification, and contain both transcribed and non-transcribed spacer segments. In the human genome there are 5 chromosomes with nucleolus organizer regions: the acrocentric chromosomes 13 (RNR1), 14 ( RNR2), 15 ( RNR3), 21 (RNR4) and 22 (RNR5). The genes that are responsible for encoding the various sub-units of rRNA are located across multiple chromosomes in humans. But the genes that encode for rRNA are highly conserved across the domains, with only the copy numbers involved for the genes having varying numbers per species. In Bacteria, Archaea, and chloroplasts the rRNA is composed of different (smaller) units, the large (23S) ribosomal RNA, 16S ribosomal RNA and 5S rRNA. The 16S rRNA is widely used for phylogenetic studies. Eukaryotes The rRNA transcribed from the approximately 600 rDNA repeats forms the most abundant section of RNA found in cells ...
