Ferdinand Bauer
Ferdinand Lucas Bauer (20 January 1760 – 17 March 1826) was an Austrian botanical illustrator who travelled on Matthew Flinders' expedition to Australia. Biography Early life and career Bauer was born in Feldsberg in 1760, the youngest son of Lucas Bauer (?–1761) – court painter to the Prince of Liechtenstein – but was left fatherless in his first year of life. The eldest son was the successor to their father's position. Together with two of his brothers, Joseph Anton and Franz Andreas, he was placed in the custody of Norbert Boccius (1729–1806), a physician and botanist who was Prior of the monastery at Feldsberg. Under the guidance of Boccius, Bauer became an astute observer of nature and was just 15 when he began to contribute miniature drawings to Boccius' collection. In 1780, Franz and Ferdinand were sent to Vienna to work under the direction of Nikolaus von Jacquin, an eminent botanist and Director of the Royal Botanical Garden at Schönbrunn Palace. There, Bau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carnivorous Plants Of Australia
''Carnivorous Plants of Australia'' is a three-volume work on carnivorous plants by Allen Lowrie. The three tomes were published in 1987, 1989, and 1998, by University of Western Australia Press. An entirely updated three-volume work by Lowrie was published by Redfern Natural History Productions in December 2013 as ''Carnivorous Plants of Australia Magnum Opus''.Lowrie, A. 2013. ''Carnivorous Plants of Australia Magnum Opus - Volume Three''. Redfern Natural History Productions, Poole. . Content The first volume deals exclusively with tuberous sundews (genus ''Drosera''). The second is devoted to pygmy sundews, but also includes three tuberous species described since the publication of the first volume, as well as two other sundews that do not fit elsewhere ('' D. glanduligera'' and '' D. hamiltonii'').

Asterales Of Australia
Asterales () is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). The order is cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the ''Lobelia deckenii'', the giant lobelia, and ''Dendrosenecio'', giant groundsels) and shrubs are also present. Asterales are organisms that seem to have evolved from one common ancestor. Asterales share characteristics on morphological and biochemical levels. Synapomorphies (a character that is shared by two or more groups through evolutionary development) include the presence in the plants of oligosaccharide ...

Soil Texture
Soil texture is a classification instrument used both in the field and laboratory to determine soil classes based on their physical texture. Soil texture can be determined using qualitative methods such as texture by feel, and quantitative methods such as the hydrometer method based on Stokes' law. Soil texture has agricultural applications such as determining crop suitability and to predict the response of the soil to environmental and management conditions such as drought or calcium (lime) requirements. Soil texture focuses on the particles that are less than two millimeters in diameter which include sand, silt, and clay. The USDA soil taxonomy and WRB soil classification systems use 12 textural classes whereas the UK-ADAS system uses 11.''Soil Science Division Staff. 2017. Soil survey sand. C. Ditzler, K. Scheffe, and H.C. Monger (eds.). USDA Handbook 18. Government Printing Office, Washington, D.C.'' These classifications are based on the percentages of sand, silt, and clay ...

Scape (botany)
In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle. Typically it takes the form of a long, leafless flowering stem rising directly from a bulb, rhizome, or similar subterranean or underwater structure. The scapes of scallions, chives, garlic chives, and garlic are used as vegetables. Etymology and usages The word ''scape'' (Latin ''scapus'', from Greek σκᾶπος), as used in botany, is fairly vague and arbitrary; various sources provide divergent definitions. Some older usages simply amount to a stem or stalk in general, but modern formal usage tends to favour the likes of "A long flower stalk rising directly from the root or rhizome", or "a long, naked, or nearly naked, peduncle, rising direct from the base of a plant, whether 1- or many-fid."Chittenden, Fred J.

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic (ecology)
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illustrationes Florae Novae Hollandiae
''Illustrationes florae Novae Hollandiae'' is an 1813 publication by the botanical illustrator Ferdinand Bauer. Bauer was scientific illustrator on board during Matthew Flinders' exploration of Australia, and as such he worked closely with the expedition's naturalist, Robert Brown. When these men returned to England in 1805, they brought with them thousands of specimens and hundreds of sketches. Initially, they planned to publish a large-scale work, to be entitled ''Illustrationes florae Novae Hollandiae'', but this venture failed, and Brown decided to publish his scientific descriptions separately, in ''Transactions of the Linnean Society of London'', and later his own ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen''. Bauer then undertook to publish a lesser work himself, with Brown providing text limited to a brief preface and some captioning. Unusually, Bauer not only did all the illustrations, but also engraved the printing plates and hand-coloured the illustrat ...

Stylidiaceae
The family Stylidiaceae is a taxon of dicotyledonous flowering plants. It consists of five genera with over 240 species, most of which are endemic to Australia and New Zealand. Members of Stylidiaceae are typically grass-like herbs or small shrubs and can be perennials or annuals. Most species are free standing or self-supporting, though a few can be climbing or scrambling ('' Stylidium scandens'' uses leaf tips recurved into hooks to climb). The pollination mechanisms of '' Stylidium'' and ''Levenhookia'' are as follows: In ''Stylidium'' the floral column, which consists of the fused stamen and style, springs violently from one side (usually under the flower) when triggered. This deposits the pollen on a visiting insect. In ''Levenhookia'', however, the column is immobile, but the hooded labellum is triggered and sheds pollen. In 1981, only about 155 species were known in the family. The current number of species by genus (reported in 2002) is as follows: ''Forstera'' - 5, '' ...

Stylidium
''Stylidium'' (also known as triggerplants or trigger plants) is a genus of dicotyledonous plants that belong to the family Stylidiaceae. The genus name ''Stylidium'' is derived from the Greek ''στύλος'' or ''stylos'' (column or pillar), which refers to the distinctive reproductive structure that its flowers possess. Pollination is achieved through the use of the sensitive "trigger", which comprises the male and female reproductive organs fused into a floral column that snaps forward quickly in response to touch, harmlessly covering the insect in pollen. Most of the approximately 300 species are only found in Australia, making it the fifth largest genus in that country. Triggerplants are considered to be protocarnivorous or carnivorous because the glandular trichomes that cover the scape and flower can trap, kill, and digest small insects with protease enzymes produced by the plant. Recent research has raised questions as to the status of protocarnivory within ''Stylidium. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
