Persoonia Linearis
''Persoonia linearis'', commonly known as the narrow-leaved geebung, is a shrub native to New South Wales and Victoria in eastern Australia. It reaches , or occasionally , in height and has thick, dark grey papery bark. The leaves are, as the species name suggests, more or less linear in shape, and are up to long, and wide. The small yellow flowers appear in summer, autumn and early winter (December to July), followed by small green fleshy fruit known as drupes. Within the genus ''Persoonia'', it is a member of the ''Lanceolata'' group of 58 closely related species. ''P. linearis'' interbreeds with several other species where they grow together. Found in dry sclerophyll forest on sandstone-based nutrient-deficient soils, ''P. linearis'' is adapted to a fire-prone environment; the plants resprout epicormic buds from beneath their thick bark after bushfires. The fruit are consumed by vertebrates such as kangaroo, possums and currawongs. As with other members of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Cranke Andrews
Henry Cranke Andrews (floruit, fl. 1794 – 1830), was an English botanist, botanical artist and engraver. As he always published as Henry C. Andrews, and due to difficulty finding records, the C. was often referred to as Charles, until a record of his marriage registration was found in 2017. He lived in Knightsbridge, and was married to Anne Kennedy, the daughter of Lee and Kennedy, John Kennedy of Hammersmith, a nurseryman who assisted Andrews in the descriptions of the plants he illustrated. He was an accomplished and unusual botanical artist, in that he was not only the artist but also the engraver, colourist, and publisher of his books in an era when most artists were only employed to draw plates. The ''Botanist's Repository'' was his first publication; issued serially in London in ten volumes between 1797 and 1812, the ''Repository'' at a half-crown an issue, provided affordable images of plants to the growing population of amateur gardeners in Britain. This was the firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalangeriformes
Phalangeriformes is a paraphyletic suborder of about 70 species of small to medium-sized arboreal marsupials native to Australia, New Guinea, and Sulawesi. The species are commonly known as possums, gliders, and cuscus. The common name "possum" for various Phalangeriformes species derives from the creatures' resemblance to the opossums of the Americas (the term comes from Powhatan language ''aposoum'' "white animal", from Proto-Algonquian *''wa·p-aʔɬemwa'' "white dog"). However, although opossums are also marsupials, Australasian possums are more closely related to other Australasian marsupials such as kangaroos. Phalangeriformes are quadrupedal diprotodont marsupials with long tails. The smallest species, indeed the smallest diprotodont marsupial, is the Tasmanian pygmy possum, with an adult head-body length of and a weight of . The largest are the two species of bear cuscus, which may exceed . Phalangeriformes species are typically nocturnal and at least partially arbo ...

On The Cultivation Of The Plants Belonging To The Natural Order Of Proteeae
''On the cultivation of the plants belonging to the natural order of Proteeae'' is an 1809 paper on the family Proteaceae of flowering plants. Although nominally written by Joseph Knight as a paper on cultivation techniques, all but 13 pages consists of an unattributed taxonomic revision now known to have been written by Richard Salisbury. Publication of the paper triggered one of the most bitter disputes in 19th century botany, because Salisbury had preempted the publication of numerous plant names that Robert Brown had intended to publish. Brown's paper had already been read to the Linnean Society of London, at meeting which Salisbury had attended, but his paper had not yet made it to print. In publishing this paper before Brown's ''On the natural order of plants called Proteaceae'' had been printed, Salisbury beat Brown to print, claiming priority for the names that Brown had authored. As a result of this, Salisbury was accused of plagiarism and ostracised from botanical cir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotyledon
A cotyledon (; ; ; , gen. (), ) is a significant part of the embryo within the seed of a plant, and is defined as "the embryonic leaf in seed-bearing plants, one or more of which are the first to appear from a germinating seed." The number of cotyledons present is one characteristic used by botanists to classify the flowering plants (angiosperms). Species with one cotyledon are called monocotyledonous ("monocots"). Plants with two embryonic leaves are termed dicotyledonous ("dicots"). In the case of dicot seedlings whose cotyledons are photosynthetic, the cotyledons are functionally similar to leaves. However, true leaves and cotyledons are developmentally distinct. Cotyledons are formed during embryogenesis, along with the root and shoot meristems, and are therefore present in the seed prior to germination. True leaves, however, are formed post-embryonically (i.e. after germination) from the shoot apical meristem, which is responsible for generating subsequent aerial por ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Banks
Sir Joseph Banks, 1st Baronet, (19 June 1820) was an English naturalist, botanist, and patron of the natural sciences. Banks made his name on the 1766 natural-history expedition to Newfoundland and Labrador. He took part in Captain James Cook's first great voyage (1768–1771), visiting Brazil, Tahiti, and after 6 months in New Zealand, Australia, returning to immediate fame. He held the position of president of the Royal Society for over 41 years. He advised King George III on the Royal Botanic Gardens, Kew, and by sending botanists around the world to collect plants, he made Kew the world's leading botanical garden. He is credited for bringing 30,000 plant specimens home with him; amongst them, he was the first European to document 1,400. Banks advocated British settlement in New South Wales and the colonisation of Australia, as well as the establishment of Botany Bay as a place for the reception of convicts, and advised the British government on all Australian matte ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Stockwell
Stockwell is a district in south west London, part of the London Borough of Lambeth, England. It is situated south of Charing Cross. Battersea, Brixton, Clapham, South Lambeth, Oval and Kennington all border Stockwell. History The name Stockwell is likely to have originated from a local well, with "stoc" being Old English for a tree trunk or post. From the thirteenth to the start of the nineteenth century, Stockwell was a rural manor at the edge of London. It included market gardens and John Tradescant's botanical garden – commemorated in Tradescant Road, which was built over it in 1880, and in a memorial outside St Stephen's church. In the nineteenth century it developed as an elegant middle-class suburb. Residents included the artist Arthur Rackham, who was born on South Lambeth Road in 1867, moving with his family to Albert Square when he was 15 years old. Another famed cultural figure who was born in Stockwell in October 1914, was theatre director Joan Litt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Persoonia Linearis Habit Grnp
''Persoonia'', commonly known as geebungs or snottygobbles, is a genus of about one hundred species of flowering plants in the family Proteaceae. Plants in the genus ''Persoonia'' are shrubs or small trees usually with smooth bark, simple leaves and usually yellow flowers arranged along a raceme, each flower with a leaf or scale leaf at the base. The fruit is a drupe. Description Persoonias are usually shrubs, sometimes small trees and usually have smooth bark. The adult leaves are simple, usually arranged alternately but sometimes in opposite pairs, or in whorls of three or four. If a petiole is present, it is short. The flowers are arranged singly or in racemes, usually of a few flowers, either in leaf axils or on the ends of the branches. Sometimes the raceme continues to grow into a leafy shoot. The tepals are free from each other except near their base, have their tips rolled back and are usually yellow. There is a single stigma on top of the ovary and surrounded by fou ...

Soil PH
Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions ( or, more precisely, ) in a solution. In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as ), and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH 9) are rare. Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element i ... ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cutting (plant)
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
