Prostanthera Cruciflora
''Prostanthera cruciflora'' is a species of flowering plant that is endemic to New South Wales. It is an erect, strongly aromatic shrub with egg-shaped leaves and white flowers with yellow streaks arranged in groups on the ends of branchlets. Description ''Prostanthera cruciflora'' is an erect, strongly aromatic shrub that typically grows to a height of with branchlets densely covered with glands. Its leaves are greyish green, egg-shaped, long and wide on a petiole long, and densely glandular. The flowers are arranged in groups of about eight, the sepals about long, forming a tube about long with two lobes, the upper lobe about long. The petals are long and white with yellow streaks on the lower lobe. Flowering occurs from August to December. Taxonomy and naming ''Prostanthera cruciflora'' was first formally described in 1967 by James Hamlyn Willis in the journal '' Muelleria''. The specific epithet (''cruciflora'') is "an allusion to the cross-shaped lower lip of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen reco ...

Prostanthera Cruciflora Habit
''Prostanthera'', commonly known as mintbush or mint bush, is a genus of about 100 species of flowering plants in the mint family Lamiaceae, and all are endemic to Australia. Plants are usually shrubs, rarely trees with leaves in opposite pairs. The flowers are arranged in panicles in the leaf axils or on the ends of branchlets. The sepals are joined at the base with two lobes. The petals are usually blue to purple or white, joined in a tube with two "lips", the lower lip with three lobes and the upper lip with two lobes or notched. Description Plants in the genus ''Prostanthera'' are usually shrubs or subshrubs, rarely trees, with leaves arranged in opposite pairs. The flowers are arranged in panicles in leaf axils or on the ends of branchlets with bracts and bracteoles at the base. The sepals are joined at the base but with two lobes. The petals form a tube with two lips, the lower lip with three, usually spreading lobes and the upper lip with two lobes or a notc ...

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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gland (botany)
In plants, a gland is defined functionally as a plant structure which secretes one or more products. This may be located on or near the plant surface and secrete externally, or be internal to the plant and secrete into a canal or reservoir. Examples include glandular hairs, nectaries, hydathodes, and the resin canals in Pinus. Notable examples Salt glands of the mangrove The salt glands of mangroves such as '' Acanthus'', '' Aegiceras'', ''Aegialitis'' and '' Avicennia'' are a distinctive multicellular trichome, a glandular hair found on the upper leaf surface and much more densely in the abaxial indumentum. On the upper leaf surface they are sunken in shallow pits, and on the lower surface they occur scattered among long nonglandular hairs composed of three or four cells. Development of the glands resembles that of the nonglandular hairs until the three-celled stage, when the short middle stalk cell appears. The salt gland continues to develop to produce two to four vac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses ( Poacea ...

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, ...

James Hamlyn Willis
James Hamlyn Willis (28 January 1910 – 10 November 1995) was an Australian botanist. He described 64 new species of plants, and published more than 880 works including the landmark two-volume ''A Handbook to plants in Victoria'' between 1962 and 1973. Life Willis was born in Oakleigh, Victoria in 1910. In 1913 he moved with his family to Stanley on the northern coast of Tasmania, Australia, where they remained until returning to Victoria in 1924. He attended Melbourne High School and in 1928, following receipt of a scholarship, began studies at the Victorian School of Forestry in Creswick, graduating with a Diploma of Forestry in 1930. For the next seven years he was employed by the Forests Commission of Victoria as a forest officer. In 1937 Willis joined the National Herbarium of Victoria and commenced studies at the University of Melbourne, graduating with a Bachelor of Science (Honours) in 1940. Between 1958 and 1959, he held the position of Australian Botanical Liaison ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muelleria (journal)
''Muelleria'' is a peer-reviewed scientific journal on botany published by the Royal Botanic Gardens Melbourne. It focuses on topics relating to plants, algae, and fungi in the southern hemisphere and Australia in particular. The journal was named in honour of Victorian Government botanist Ferdinand von Mueller. ''Muelleria'' commenced publication in 1955 with funding from the Maud Gibson Trust. The trust was initiated in 1945 following the donation of £20,000 by Maud Gibson, a daughter of William Gibson, founder of the Foy & Gibson department store chain. ''Muelleria'' was one of a number of botanical journals initiated by Australian herbaria after World War II, reflecting the increased level of botanical research undertaken at this time. James Hamlyn Willis was the editor of the three initial issues.

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus '' Homo'' and within this genus to the species '' Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petal
Petals are modified leaves that surround the reproductive parts of flowers. They are often 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 genera such as '' Aloe'' and '' Tulipa''. Conversely, genera such as ''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. Since they include Liliales, an alte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Kaputar National Park
The Mount Kaputar National Park is a national park located in New South Wales, Australia, surrounding the proximities of Mount Kaputar, a volcano active between 17 and 21 million years ago. It is located east of Narrabri and northwest of Sydney. Millions of years of erosion have since carved the volcanic region into the lava terraces, volcanic plugs, and dykes of Nandewar Range. The central feature of the region is Mount Kaputar, the park's namesake, which rises to an altitude of . The 360 degree view from the summit of the mountain encompasses one-tenth of New South Wales' area or . The park protects a wide range of biomes, including semi-arid woodland, subalpine heath, and eucalypt forests, and provides a habitat for a range of animals, including bats, birds, wallabies, quolls, and the unique red triangle slug (''Triboniophorus graeffei''), which is known to appear after rainfall. History Before it was a national park, the area was used largely as grazing lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
