Persoonia Pinifolia
''Persoonia pinifolia'', commonly known as pine-leaved geebung or as mambara in the Cadigal language, is a species of flowering plant in the family Proteaceae and is endemic to the Sydney region of New South Wales. It is an upright, woody shrub with soft, pine-like foliage and long, terminal racemes of small yellow flowers in late winter to summer. Description ''Persoonia pinifolia'' grows as an upright woody shrub up to high and wide. Its young branches are moderately hairy. The leaves are soft and thread-like, long, about wide, moderately hairy when young, but become glabrous as they age. The ends of the leaves are often curved. The flowers are arranged in long, terminal racemes making them much more conspicuous than those of most other persoonias. The flowers each have a moderately hairy pedicel long and there is a small leaf at the base of each flower. The flower is composed of four tepals long, which are fused at the base but with the tips rolled back. The central style ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maranoa Botanic Gardens
The Maranoa Botanic Gardens is a botanical garden in Balwyn, Melbourne. It is significant as being one of the first and only botanical gardens in the world dedicated solely to Australian native plants. History Establishment Maranoa Gardens began in the early 1890s, when Mr John Middleton Watson purchased 1.4 hectares in Balwyn, a suburb of Melbourne, Australia, for a private garden. He planted many Australian and New Zealand native trees and shrubs and the area was maintained purely as a garden. He named the gardens Maranoa after a river in Queensland, from native words meaning flowing, alive or running. As a member of the Field Naturalists Club of Victoria, he was keenly interested in native and indigenous flora. At the time, native Australian flora was not widely used in gardening; introduced English and other exotic species were used instead. Public gardens The former City of Camberwell (since merged into the City of Boroondara) acquired the area in 1922 and continued th ...

Port Jackson
Port Jackson, commonly known as Sydney Harbour, is a natural harbour on the east coast of Australia, around which Sydney was built. It consists of the waters of Sydney Harbour, Middle Harbour, North Harbour and the Lane Cove and Parramatta Rivers. The harbour is an inlet of the Tasman Sea (part of the South Pacific Ocean). It is the location of significant landmarks such as the Sydney Opera House and Sydney Harbour Bridge. The location of the first European settlement and colony on the Australian mainland, Port Jackson has continued to play a key role in the history and development of Sydney. Port Jackson, in the early days of the colony, was also used as a shorthand for Sydney and its environs. Thus, many botanists, see, e.g., Robert Brown's '' Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', described their specimens as having been collected at Port Jackson. Many recreational events are based on or around the harbour itself, particularly Sydney New Year's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Persoonia
''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 Leaf#Divisions of the blade, simple, usually arranged alternately but sometimes in opposite pairs, or in Whorl (botany), whorls of three or four. If a Petiole (botany), petiole is present, it is short. The flowers are arranged singly or in racemes, usually of a few flowers, either in leaf wikt:axil, 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 y ...

Gibberellic Acid
Gibberellic acid (also called gibberellin A3 or GA3) is a hormone found in plants and fungi. Its chemical formula is C19H22O6. When purified, it is a white to pale-yellow solid. Plants in their normal state produce large amounts of GA3. It is possible to produce the hormone industrially using microorganisms.Camara, M. C. et al (2015) General Aspects and Applications of Gibberelins and Gibberellic Acid in Plants. In: Hardy, J.. (Org.). Gibberellins and Gibberellic Acid: Biosynthesis, Regulation and Physiological Effects. 1ed.Hauppauge: Nova Science Publishers, 2015, v., p. 1-21. Gibberellic acid is a simple gibberellin, a pentacyclic diterpene acid promoting growth and elongation of cells. It affects decomposition of plants and helps plants grow if used in small amounts, but eventually plants develop tolerance to it. GA stimulates the cells of germinating seeds to produce mRNA molecules that code for hydrolytic enzymes. Gibberellic acid is a very potent hormone whose natural occ ...

Cluster Root
Cluster roots, also known as proteoid roots, are plant roots that form clusters of closely spaced short lateral rootlets. They may form a two- to five-centimetre-thick mat just beneath the leaf litter. They enhance nutrient uptake, possibly by chemically modifying the soil environment to improve nutrient solubilisation. As a result, plants with proteoid roots can grow in soil that is very low in nutrients, such as the phosphorus-deficient native soils of Australia. They were first described by Adolf Engler in 1894, after he discovered them on plants of the family Proteaceae growing in Leipzig Botanic Gardens. In 1960, Helen Purnell examined 44 species from ten Proteaceae genera, finding proteoid roots in every genus except ''Persoonia''; she then coined the name "proteoid roots" in reference to the plant family in which it was known to occur. Proteoid roots are now known to occur in 27 different Proteaceae genera, plus around 30 species from other families, including Betulaceae, C ...

Seed Dispersal
In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living (Biotic component, biotic) vectors such as birds. Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. The patterns of seed dispersal are determined in large part by the dispersal mechanism and this has important implications for the demographic and genetic structure of plant populations, as well as wikt:migration, migration patterns and species interactions. There are five main modes of seed dispersal: Gravitation, gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. These modes are typically inferred based on adaptations, such as wings or fle ...

Lewin's Honeyeater
Lewin's honeyeater (''Meliphaga lewinii'') is a bird that inhabits the ranges along the east coast of Australia. It has a semicircular ear-patch, pale yellow in colour. The name of this bird commemorates the Australian artist John Lewin. Another name is Yellow-eared Honeyeater https://anet.be/record/opacanet/c:lvd:6878811/E Description The Lewin's honeyeater is small to medium in size . It is dark greenish-grey in colour, with a creamy yellow gape (i.e., the fleshy corners of the mouth). It has large, yellowish, crescent-shaped ear-patches, which distinguish it from other honeyeaters, apart from two similar, but smaller, species in tropical Queensland. In flight, the pale yellow edges of the flight feathers can be seen. The bill is black and the eye is blue-grey. Both sexes are similar in appearance. Young Lewin's honeyeaters are similar to the adults, but have brown eyes. The strong 'machine gun-like' rattling notes of Lewin's honeyeater are heard over long distances, and reve ...

Regent Bowerbird
The regent bowerbird (''Sericulus chrysocephalus'') is a medium-sized, up to 25 cm long, sexually dimorphic bowerbird. The male bird is black with a golden orange-yellow crown, mantle and black-tipped wing feathers. It has yellow bill, black feet and yellow iris. The female is a brown bird with whitish or fawn markings, grey bill, black feet and crown. The name commemorates a prince regent of the United Kingdom. Diet The diet consists mainly of fruits, berries and insects. Behaviour All male bowerbirds build bowers, which can be simple ground clearings or elaborate structures, to attract female mates. Regent bowerbirds in particular are known to mix a muddy greyish blue or pea green "saliva paint" in their mouths which they use to decorate their bowers. The male builds an avenue-type bower consisting of two walls of sticks, decorated with shells, seeds, leaves and berries. Regents will sometimes use wads of greenish leaves as "paintbrushes" to help spread the substance, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satin Bowerbird
The satin bowerbird (''Ptilonorhynchus violaceus'') is a species of passerine bird in the bowerbird family Ptilonorhynchidae that is endemic to eastern Australia. It is the only species placed in the genus ''Ptilonorhynchus''. Taxonomy The satin bowerbird was species description, formally described in 1816 by the French ornithologist Louis Pierre Vieillot, Louis Vieillot. He placed it with the choughs in the genus ''Pyrrhocorax'' and coined the binomial name ''Pyrrhocorax violaceus''. Viellot specified the type locality (biology), type locality as "Nouvelle-Hollande" which is taken to be Sydney in New South Wales, Australia. The satin bowerbird is now the only species placed in the genus ''Ptilonorhynchus'' that was introduced in 1820 by German naturalist Heinrich Kuhl. He specified the type species as ''Ptilonorhynchus holosericeus'', which is a junior synonym of Vieillot's ''Pyrrhocorax violaceus''.
