Olearia Plucheacea
''Olearia plucheacea'' is a species of flowering plant in the family Asteraceae and is endemic to inland Western Australia. It is an erect, open shrub with scattered hairy, thread-like to linear leaves, and white and yellow daisy-like inflorescences. Description ''Olearia plucheacea'' is an erect, open shrub that typically grows to a height of up to , its stems and leaves covered with simple and glandular hairs. The leaves are arranged alternately, scattered along the branchlets, sticky, thread-like to narrowly linear, long and wide. The heads or daisy-like "flowers" are arranged in dense panicles on the ends of branches on a peduncle up to long, the leaves grading to the narrowly conical involucre at the base. Each head is in diameter with 5 to 7 white ray florets, the ligule long, surrounding 3 to 5 yellow disc florets. Flowering occurs from August to October and the fruit is an achene long, the pappus with 25 to 38 bristles. Taxonomy ''Olearia plucheacea'' was first ...

Pappus (botany)
In Asteraceae, the pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower. It functions as a wind-dispersal mechanism for the seeds. The term is sometimes used for similar structures in other plant families e.g. in certain genera of the Apocynaceae, although the pappus in Apocynaceae is not derived from the calyx of the flower. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the dandelion plays a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olearia
''Olearia'', most commonly known as daisy-bush, is a genus of flowering plants belonging to the family Asteraceae, the largest of the flowering plant families in the world. Olearia are found in Australia, New Guinea and New Zealand. The genus includes herbaceous plants, shrubs and small trees. The latter are unusual among the Asteraceae and are called tree daisies in New Zealand. All bear the familiar daisy-like composite flowerheads in white, pink, mauve or purple. Description Plants in the genus ''Olearia'' are shrubs of varying sizes, characterised by a composite flower head arrangement with single-row ray florets enclosed by small overlapping bracts arranged in rows. The flower petals are more or less equal in length. The centre of the bi-sexual floret is disc shaped and may be white, yellowish or purplish, generally with 5 lobes. Flower heads may be single or clusters in leaf axils or at the apex of branchlets. Leaves may be smooth, glandular or with a sticky secretion. T ...

Pluchea
''Pluchea'' is a genus of flowering plants in the tribe Inuleae within the family Asteraceae. Members of this genus might be known as camphorweeds, plucheas, or less uniquely fleabanes. Some, such as ''P. carolinensis'' and ''P. odorata'', are called sourbushes. There are plants of many forms, from annual and perennial herbs to shrubs and trees, and there is variation in the morphology of leaves, flowers, and fruits.Perera, W., et al. (2007)Flavonols from leaves of ''Pluchea carolinensis'' (Jacq.) G.Don (Asteraceae).'' Revista Latinoamericana de Química'' 35(3), 68-73.

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 credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuytsia (journal)
''Nuytsia'' is a peer-reviewed scientific journal published by the Western Australian Herbarium. It publishes papers on systematic botany, giving preference to papers related to the flora of Western Australia. Nearly twenty percent of Western Australia's plant taxa have been published in ''Nuytsia''. The journal was established in 1970 and has appeared irregularly since. The editor-in-chief is Kevin Thiele. ''Nuytsia'' is named after the monospecific genus ''Nuytsia'', whose only species is '' Nuytsia floribunda'', the Western Australian Christmas tree. Occasionally, the journal has published special issues, such as an issue in 2007 substantially expanding described species from Western Australia. Publication details The record of the issues published is found at the ''FloraBase ''FloraBase'' is a public access web-based database of the flora of Western Australia. It provides authoritative scientific information on 12,978 taxa, including descriptions, maps, images, conservati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium (aka f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
