Hyalosperma Praecox
''Hyalosperma praecox'' commonly known as fine-leaf sunray, is a flowering plant in the family Asteraceae. It is an upright, annual herb with stems branching from the base and yellow or white flowers and grows in New South Wales and Victoria. Description ''Hyalosperma praecox'' is an upright, multi-stemmed annual high with stems arising from the base. The leaves are narrow, green, long, decreasing in size toward the apex, upper leaves with a dry appendage, and tapering to a point. The white or yellow flowers are borne singly, bracts in several rows, outer bracts about long, inner bracts about long, corolla has five lobes and about long. Flowering occurs in spring and the fruit is an oval-shaped cypsela about long and may be either smooth or warty. Taxonomy and naming This species was first described by Ferdinand von Mueller and given the name ''Helipterum praecox''. In 1989 Paul Graham Wilson changed the name to ''Hyalosperma praecox'' and the description was published i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Graham Wilson
Paul Graham Wilson (born 1928) is an Australian botanist. He has been a most prolific contributor to the journal ''Nuytsia'', contributing to the first issue in 1970 and to the 12th volume in 1998, which was dedicated to him for his contributions to plant taxonomy and to celebrate his 70th birthday. Since his retirement from the Western Australian Herbarium in 1993, he has helped to maintain a comprehensive census of the flora of Western Australia. Wilson has mostly published papers dealing with the plant families Rutaceae, Asteraceae and Chenopodiaceae. Selected publications * A taxonomic revision of the genera ''Crowea'', ''Eriostemon'', and ''Phebalium'' (Rutaceae) * A taxonomic review of the genera ''Eriostemon'' and ''Philotheca ''Philotheca'' is a genus of about fifty species of flowering plants in the family Rutaceae. Plants in this genus are shrubs with simple leaves arranged alternately along the stems, flowers that usually have five sepals, five petals and ten st ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Bract
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale. Bracts are usually different from foliage leaves. They may be smaller, larger, or of a different color, shape, or texture. Typically, they also look different from the parts of the flower, such as the petals or sepals. A plant having bracts is referred to as bracteate or bracteolate, while one that lacks them is referred to as ebracteate and ebracteolate, without bracts. Variants Some bracts are brightly-coloured and serve the function of attracting pollinators, either together with the perianth or instead of it. Examples of this type of bract include those of ''Euphorbia pulcherrima'' (poinsettia) and ''Bougainvillea'': both of these have large colourful bracts surrounding much smaller, less colourful flowers. In grasses, each floret (flower) is enclosed in a pair of papery bracts, called the lemma (lower bract) and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corolla (botany)
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ferdinand Von Mueller
Baron Sir Ferdinand Jacob Heinrich von Mueller, (german: Müller; 30 June 1825 – 10 October 1896) was a German-Australian physician, geographer, and most notably, a botanist. He was appointed government botanist for the then colony of Victoria (Australia) by Governor Charles La Trobe in 1853, and later director of the Royal Botanic Gardens, Melbourne. He also founded the National Herbarium of Victoria. He named many Australian plants. Early life Mueller was born at Rostock, in the Grand Duchy of Mecklenburg-Schwerin. After the early death of his parents, Frederick and Louisa, his grandparents gave him a good education in Tönning, Schleswig. Apprenticed to a chemist at the age of 15, he passed his pharmaceutical examinations and studied botany under Professor Ernst Ferdinand Nolte (1791–1875) at Kiel University. In 1847, he received his degree of Doctor of Philosophy from Kiel for a thesis on the plants of the southern regions of Schleswig. Mueller's sister Bertha had be ...

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] |
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] |
Gnaphalieae
The Gnaphalieae are a tribe of flowering plants in the family Asteraceae. It is most closely related to the tribes Anthemideae, Astereae, and Calenduleae. Characteristics This group is most diverse in South America, Southern Africa and Australia. There are only a few genera with species native to temperate regions: ''Anaphalis'', ''Antennaria'', ''Gamochaeta'', ''Helichrysum'', ''Leontopodium'' (Edelweiss), '' Phagnalon'', ''Diaperia'', and ''Pseudognaphalium''. The classification of the tribe into subtribes is unclear, with a number of past classifications not being supported by late 20th-century evidence. Genera Gnaphalieae genera recognized by the Global Compositae Database as April 2022: *'' × Filfia'' *'' Acanthocladium'' *''Achyrocline'' *''Acomis'' *'' Actinobole'' *'' Alatoseta'' *''Ammobium'' *'' Amphiglossa'' *'' Anaphalioides'' *''Anaphalis'' *'' Anaxeton'' *'' Ancistrocarphus'' *'' Anderbergia'' *'' Anemocarpa'' *'' Angianthus'' *''Antennaria'' *' ...

Flora Of Victoria (state)
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
