Helichrysum Bracteatum
''Xerochrysum bracteatum'', commonly known as the golden everlasting or strawflower, is a flowering plant in the family Asteraceae native to Australia. Described by Étienne Pierre Ventenat in 1803, it was known as ''Helichrysum bracteatum'' for many years before being transferred to a new genus ''Xerochrysum'' in 1990. It is an annual up to tall with green or grey leafy foliage. Golden yellow or white flower heads are produced from spring to autumn; their distinctive feature is the papery bracts that resemble petals. The species is widespread, growing in a variety of habitats across the country, from rainforest margins to deserts and subalpine areas. The golden everlasting serves as food for various larvae of lepidopterans (butterflies and moths), and adult butterflies, hoverflies, native bees, small beetles, and grasshoppers visit the flower heads. The golden everlasting has proven very adaptable to cultivation. It was propagated and developed in Germany in the 1850s, and ann ...

Étienne Pierre Ventenat
Étienne Pierre Ventenat (1 March 1757 – 13 August 1808) was a French botanist born in Limoges. He was the brother of naturalist Louis Ventenat (1765–1794). While employed as director of the ecclesiastic library Sainte-Geneviève in Paris, Ventenat took a trip to England. Here he investigated the country's botanical gardens, inspiring him to pursue a vocation in sciences. Following his time at library he became an active botanist, studying under and collaborating with botanist Charles Louis L'Héritier de Brutelle (1746–1800). In 1795 he was elected a member of the ''Institut national des sciences et des arts'', later known as the ''Académie des sciences''. In 1794 he wrote a treatise on the principles of botany titled ''Principes de botanique, expliqués au Lycée républicain par Ventenat''. After publication he became so disappointed with its mediocrity that he reportedly made efforts to procure all copies of the book and have them destroyed. In 1798 he published a Fren ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Xerochrysum Bicolor
''Xerochrysum bicolor'' is a flowering plant in the family Asteraceae, native to Tasmania, where it is found in wetter habitats near the coast. It was originally described by Lindley in 1835 as ''Helichrysum bicolor'', before gaining its current name in 2001. It is a compact annual or perennial, which normally grows to about 40 cm in height and 50 cm wide, and is usually simple or few-branched. The leaves are lanceolate and range from 2.5 to 10 cm long by 0.3 to 1.4 cm wide. The flowerheads are on stalks and have a diameter of 3 to 4 cm. The inflorescence bracts are papery, the outer ones orange-brown in colour, and the inner ones yellow. It is distinguished from '' X. bracteatum'' by its narrower leaves. The species may be sunk into ''Xerochrysum bracteatum ''Xerochrysum bracteatum'', commonly known as the golden everlasting or strawflower, is a flowering plant in the family Asteraceae native to Australia.

Cryptic Species
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Helichrysum
The genus ''Helichrysum'' consists of an estimated 600 species of flowering plants in the sunflower family (Asteraceae). The type species is ''Helichrysum orientale''. They often go by the names everlasting, immortelle, and strawflower. The name is derived from the Anicent Greek words (helios, sun) and (, gold). It occurs in Africa (with 244 species in South Africa), Madagascar, Australasia and Eurasia. The plants may be annuals, herbaceous perennials or shrubs, growing to a height of . The genus was a wastebasket taxon, and many of its members have been reclassified in smaller genera, most notably the Everlastings, now in the genus ''Xerochrysum''. Their leaves are oblong to lanceolate. They are flat and pubescent on both sides. The bristles of the pappus are scabrous, barbellate, or plumose. The receptacle (''base of the flower head'') is often smooth, with a fringed margin, or honey-combed, and resemble daisies. They may be in almost all colors, except blue. There are man ...

Henckel Von Donnersmarck
The House of Henckel von Donnersmarck is an old Austro-German noble family that originated in the former region of Spiš in Upper Hungary, now in Slovakia. The founder of the family was Henckel de Quintoforo in the 14/15th century. The original seat of the family was in Donnersmarck (Slovakian: Spišský Štvrtok). History In 1417, during the time of the Council of Constance, the Holy Roman Emperor and Hungarian King, Sigismund of Luxembourg, granted the three brothers Peter, Jakob and Nicholas a coat of arms.von Ehrenkrook & von Hueck (eds.), ''Genealogisches Handbuch,'' pp. 590ff. During the 15th and 16th centuries, John II (1481–1539), an eminent scholar, corresponded with Martin Luther, Erasmus of Rotterdam and Philipp Melanchthon. He began his career as a pastor in Levoča and Košice. Later, he stayed at the court of Louis II of Hungary and his wife, Maria of Austria. In 1531, he came to Silesia and became a canon in Breslau (Wroclaw), Silesia. He died there eig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Australian Plants
The Australian Native Plants Society (Australia) (ANPSA) is a federation of seven state-based member organisations for people interested in Australia's native flora, both in aspects of conservation and in cultivation. A national conference is held biennially for members of the state-based societies. The combined membership is around 9000 people. History The Society for Growing Australian Plants (SGAP) was established in 1957 by a group of people who "pledged to promote the establishment and breeding of Australian native plants for garden, park and farm". By 1958 active regional Societies had been established in six States and the ACT with the Federal Association (ASGAP) being formed in 1962 Initially the focus was on growing and learning about Australian Flora more for home and amenities plantings – members included botanists and horticulturists as well as enthusiastic laypeople. As time has gone on, there has been an increasing focus on conservation, and advocacy for conserv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
