Systematic Census Of Australian Plants
The ''Systematic census of Australian plants, with chronologic, literary and geographic annotations'', more commonly known as the ''Systematic Census of Australian Plants'', also known by its standard botanic abbreviation ''Syst. Census Austral. Pl.'', is a survey of the vascular flora of Australia prepared by Government botanist for the state of Victoria Ferdinand von Mueller and published in 1882. Von Mueller describes the development of the census in the preface of the volume as an extension of the seven volumes of the ''Flora Australiensis'' written by George Bentham. A new flora was necessary since as more areas of Australia were explored and settled, the flora of the island-continent became better collected and described. The first census increased the number of described species from the 8125 in ''Flora Australiensis'' to 8646. The book records all the known species indigenous to Australia and Norfolk Island; with records of species distribution. Von Mueller noted that b ...

Systemic Census Of Australian Plants
Systemic fundamental to a predominant social, economic, or political practice. This refers to: In medicine In medicine, ''systemic'' means affecting the whole body, or at least multiple organ systems. It is in contrast with ''topical'' or ''local''. *Systemic administration, a route of administration of medication so that the entire body is affected *Systemic circulation, carries oxygenated blood from the heart to the body and then returns deoxygenated blood back to the heart *Systemic disease, an illness that affects multiple organs, systems or tissues, or the entire body *Systemic effect, an adverse effect of an exposure that affects the body as a whole, rather than one part *Systemic inflammatory response syndrome, an inflammatory state affecting the whole body, frequently in response to infection *Systemic lupus erythematosus, a chronic autoimmune connective tissue disease that can affect any part of the body *Systemic scleroderma, also known as systemic sclerosis, a systemic ...

Veronica Peregrina
''Veronica peregrina'' is a species of flowering plant in the plantain family known by several common names including neckweed, American speedwell, purslane speedwell and hairy purslane speedwell. It is native to the Americas, and is known on other continents as an introduced species and a common weed. It can be weedy in its native range as well, growing on roadsides, on fields, and in other disturbed habitat. It is an annual herb growing from a taproot. The two subspecies are defined generally on the basis of hairiness: ssp. ''xalapensis'' is coated in glandular hairs and ssp. ''peregrina'' is a hairless variety. The plant produces erect stems up to about 30 centimeters tall. The leaves vary in shape from linear to lance-shaped to spoon-shaped with smooth or serrated edges; the lower leaves are borne on petioles. The inflorescence is a loose terminal raceme of flowers and lance-shaped bract In botany, a bract is a modified or specialized leaf, especially one associated with a ...

Books About Australian Natural History
A book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover. The technical term for this physical arrangement is ''codex'' (plural, ''codices''). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and still considered as an investment of time to read. In a restricted sense, a book is a self-sufficient section or part of a longer composition, a usage reflecting that, in antiquity, long works had to be written on several scrolls and each scroll had to be identified by the book it contained. Each part of Aristotle's ''Physics'' is called a bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Censuses
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific metho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century Books
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Bird Count
The Australian Bird Count (ABC) was a project of the Royal Australasian Ornithologists Union (RAOU). Following the first and successful Atlas of Australian Birds project, which led to the publication of a book on the distribution of Australian birds in 1984, it was suggested by Ken Rogers (ornithologist), Ken Rogers that the RAOU should next look at bird migration and other movements in Australia. Methodology for a suitable project involving volunteers was worked out through experimental fieldwork and a workshop on ‘Monitoring the Populations and Movements of Australian Birds’. A project manager, [Stephen Ambrose], was appointed and project fieldwork ran from January 1989 to August 1995. Some 950 volunteer observers carried out 79,000 surveys, for fixed 20-minute periods in 1700 three-hectare locations over Australia. Project management started at the Australian Museum in Sydney and was later moved to the RAOU National Office in Melbourne. Financial support came at first fro ...

Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For twenty years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, and Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave. From age seven, Hooker attended his father's lectures at Glasgow University, taking an early interest in plant distribution and the voyages of explorers like Captain James Cook.

Eupatorium Cannabinum
''Eupatorium cannabinum'', commonly known as hemp-agrimony, or holy rope, is a herbaceous plant in the family Asteraceae. It is a robust Perennial plant, perennial native to many areas of Europe. The alkaloids may be present in the plant material as their N-oxides. Pharmacology ''Eupatorium cannabinum'' is used in the European traditional medicine as anti-inflammatory agent for respiratory tract diseases, and several of its sesquiterpene lactone constituents were identified to have anti-inflammatory effect in isolated human neutrophils, with the anti-inflammatory action of the sesquiterpene lactone eupatoriopicrin being verified also in mouse peritonitis model. ;Subspecies *''Eupatorium cannabinum'' L. subsp.
