Eremophila Glabra
''Eremophila glabra'', commonly known as tar bush, is a plant in the figwort family, Scrophulariaceae and is endemic to Australia. It is sometimes a low, ground-hugging and sometimes an erect shrub. The leaves are variable in size and shape and there is a range of flower colours. In spite of its scientific name, not all forms of the plant are glabrous but most have many small, raised glands on the stems, flowers and leaves. Description ''Eremophila glabra'' grows to in height, sometimes a prostrate shrub and sometimes erect. The leaves are arranged alternately, sometimes crowded, other times sparse, usually lance-shaped but they may also be linear to egg-shaped. They are long and wide, the end pointed and the base tapering gradually towards the stem. The leaves and stems are covered with small, raised glands. The flowers are red, orange, yellow or yellowish green, lack spots and are arranged singly or in pairs in the leaf axils on a stalk which is long. There are 5 sepals w ...

Australian Botanic Garden Mount Annan
The Australian Botanic Garden Mount Annan is a botanical garden located in a hilly area of the southwestern Sydney suburb of , between Campbelltown and Camden, New South Wales. It is the largest botanical garden in Australia, specializing in native plants, with a collection of over 4000 species. Officially opened in 1988, it was known as Mount Annan Botanic Garden, until 2011. History and management The traditional custodians of the land now occupied by the gardens were the Dharawal indigenous Australian people. Later, it became dairy pasture land, before the land was acquired by the Royal Botanic Gardens and Domain Trust in 1984 and The garden was opened to the public in 1988 by the Duchess of York, Sarah Ferguson. The gardens are managed by the Botanic Gardens Trust trading the Botanic Gardens & Centennial Parklands, that also has responsibility for the Royal Botanic Gardens, Sydney and the Blue Mountains Botanic Garden at .

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] |

Carl Hansen Ostenfeld
Carl Emil Hansen Ostenfeld (born Carl Emil Ostenfeld-Hansen) (3 August 1873 – 16 January 1931) was a Danish systematic botanist. He graduated from the University of Copenhagen under professor Eugenius Warming. He was a keeper at the Botanical Museum 1900–1918, when he became professor of botany at the Royal Veterinary and Agricultural University. In 1923, by the early retirement of Raunkiær's, Ostenfeld became professor of botany at the University of Copenhagen and director of the Copenhagen Botanical Garden, both positions held until his death in 1931. He was a member of the Royal Danish Academy of Sciences and Letters and served on the board of directors of the Carlsberg Foundation. Ostenfeld is known as an explorer of the Danish flora, including marine plankton, as well as the flora of Western Australia. Ostenfeld participated in the Ingolf expedition (1885-86) to the waters around Iceland and Greenland, and in 1911 in the International Phytogeographic Excursion ...

Prodromus Florae Novae Hollandiae Et Insulae Van Diemen
''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' (Prodromus of the Flora of New Holland and Van Diemen's Land) is a flora of Australia written by botanist Robert Brown and published in 1810. Often referred to as ''Prodromus Flora Novae Hollandiae'', or by its standard botanical abbreviation ''Prodr. Fl. Nov. Holland.'', it was the first attempt at a survey of the Australian flora. It described over 2040 species, over half of which were published for the first time. Brown's ''Prodromus'' was originally published as Volume One, and following the ''Praemonenda'' (Preface), page numbering commences on page 145. Sales of the ''Prodromus'' were so poor, however, that Brown withdrew it from sale. Due to the commercial failure of the first volume, pages 1 to 144 were never issued, and Brown never produced the additional volumes that he had planned. In 1813, a book of illustrations for the ''Prodromus'' was published separately by Ferdinand Bauer under the title ''Ferdinandi Ba ...

Robert Brown (Scottish Botanist From Montrose)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose, Angus, Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown (Scottis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Prostrate Shrub
A prostrate shrub is a woody plant, most of the branches of which lie upon or just above the ground, rather than being held erect as are the branches of most trees and shrubs. Background Prostration may occur because the supporting tissues in stems are not strong enough to support the weight of the plant, causing the plant to bend until it reaches the ground. Alternatively, it may occur because of a genetic disposition for branches to grow horizontally on or just under the ground; for example, as a strategy to avoid overly strong sunlight. Finally, environmental factors such as strong winds laden with sand or salt may tend to prune away erect branches, thereby creating a prostrate habit in plants that may not be predisposed to prostration. Ecology Prostrate shrubs are used in horticulture as groundcovers and in hanging baskets, and to bind soils and prevent erosion in remedial landscaping. They are also important components of rock gardens. The shrinking size of urban gardens has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
