Olearia Curticoma
''Olearia curticoma'' is a species of flowering plant in the family Asteraceae and is endemic to Victoria. It is an erect shrub with glabrous, sticky branchlets, linear leaves and white and yellow, daisy-like inflorescences. Description ''Olearia curticoma'' is an erect shrub that typically grows to a height of up to about , and has glabrous, sticky branchlets. The leaves are arranged alternately along the branchlets, linear, long and wide and more or less glabrous. The heads or daisy-like "flowers" are arranged singly at or near the ends of branchlets and are in diameter on a peduncle long. Each head has ten to sixteen ray florets, the ligule white and long, surrounding about twice as many yellow disc florets. Flowering occurs from December to May and the fruit is a cylindrical achene, the pappus short and white. Taxonomy and naming ''Olearia curticoma'' was first formally described in 2014 by Neville Grant Walsh in the journal '' Muelleria'' from specimens he collecte ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Pappus (botany)
In Asteraceae, the pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower. It functions as a wind-dispersal mechanism for the seeds. The term is sometimes used for similar structures in other plant families e.g. in certain genera of the Apocynaceae, although the pappus in Apocynaceae is not derived from the calyx of the flower. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the dandelion plays a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Victoria (Australia)
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olearia
''Olearia'', most commonly known as daisy-bush, is a genus of flowering plants belonging to the family Asteraceae, the largest of the flowering plant families in the world. Olearia are found in Australia, New Guinea and New Zealand. The genus includes herbaceous plants, shrubs and small trees. The latter are unusual among the Asteraceae and are called tree daisies in New Zealand. All bear the familiar daisy-like composite flowerheads in white, pink, mauve or purple. Description Plants in the genus ''Olearia'' are shrubs of varying sizes, characterised by a composite flower head arrangement with single-row ray florets enclosed by small overlapping bracts arranged in rows. The flower petals are more or less equal in length. The centre of the bi-sexual floret is disc shaped and may be white, yellowish or purplish, generally with 5 lobes. Flower heads may be single or clusters in leaf axils or at the apex of branchlets. Leaves may be smooth, glandular or with a sticky secretion. T ...

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 ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Mitchell River National Park (Victoria)
The Mitchell River National Park is a national park located in the Gippsland region of Victoria, Australia. The national park is situated approximately east of Melbourne via the Princes Highway, and approximately northwest of Bairnsdale. The northern portion of the park may be accessed via . Mitchell River The park's central feature is the Mitchell River, which is the largest unregulated river in Victoria and provides a unique example of riparian ecology. According to a Land Conservation Council Rivers & Streams Special Investigation completed in 1990, "It is an important example of the large-scale biological systems that were once widespread in south-eastern Australia." In 1992 the Mitchell River was listed as a Heritage River. The park The national park surrounds the spectacular Mitchell River where it has cut its way through rock strata creating high cliffs and several gorges. The park originated as the ''Glenaladale National Park'' in 1963 following a donation of o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muelleria (journal)
''Muelleria'' is a peer-reviewed scientific journal on botany published by the Royal Botanic Gardens Melbourne. It focuses on topics relating to plants, algae, and fungi in the southern hemisphere and Australia in particular. The journal was named in honour of Victorian Government botanist Ferdinand von Mueller. ''Muelleria'' commenced publication in 1955 with funding from the Maud Gibson Trust. The trust was initiated in 1945 following the donation of £20,000 by Maud Gibson, a daughter of William Gibson, founder of the Foy & Gibson department store chain. ''Muelleria'' was one of a number of botanical journals initiated by Australian herbaria after World War II, reflecting the increased level of botanical research undertaken at this time. James Hamlyn Willis was the editor of the three initial issues. Editors-in-chief The following persons have been or are editor-in-chief: *James Hamlyn Willis (Vol 1. 1956–1967) *Rex Bertram Filson (Vol. 2-Vol. 3, no. 3. 1969–1976) * ...

Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium (aka f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
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] |
Ligule
A ligule (from "strap", variant of ''lingula'', from ''lingua'' "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges. A ligule is also a strap-shaped extension of the corolla, such as that of a ray floret in plants in the daisy family Asteraceae. Poaceae and Cyperaceae The ligule is part of the leaf that is found at the junction of the blade and sheath of the leaf. It may take several forms, but it is commonly some form of translucent membrane or a fringe of hairs. The membranous ligule can be very short 1–2 mm (Kentucky bluegrass, ''Poa pratensis'') to very long 10–20 mm (Johnson grass, ''Sorghum halepense''), it can also be smooth on the edge or very ragged. Some grasses do not have a ligule, for example barnyardgrass (''Echinochloa crus-galli''). A ligule can also be defined as a membrane-like tissue or row of delicate hairs typically found in grasses at the junction of the leaf sheath and blade. The ...
