Felicia (plant)
''Felicia'' is a genus of small shrubs, Perennial plant, perennial or Annual plant, annual herbaceous plants, with 85 known species, that is assigned to the Asteraceae, daisy family (Compositae or Asteraceae). Like in almost all Asteraceae, the individual flowers are Merosity, 5-merous, small, and clustered in typical heads, which are surrounded by an Bract#Involucral bracts, involucre of between two and four Whorl (botany), whorls of bracts. In ''Felicia'', the centre of the head is taken by yellow, seldom whitish or blackish blue Asteraceae#Floral heads, disc florets, and is almost always surrounded by one single whorl of mostly purple, sometimes blue, pink, white, or yellow Asteraceae#Floral heads, ligulate florets, and rarely, ligulate florets are absent. These florets sit on a common base (or Receptacle (botany), receptacle) and are not individually subtended by a bract (or palea). Most species occur in the Cape Floristic Region, which is most probably the area where the genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Felicia Amoena
''Felicia amoena'', known as the soft felicia, is a variably hairy, sometimes glandular, Biennial plant, biennial or perennial plant, of about high, that is assigned to the family Asteraceae. It is somewhat woody at its base, roots at the nodes if these contact the soil, and has ascending branches. The leaves are oppositely arranged along the stems at and just above a branching fork, further up the leaves alternate. The flower heads sit individually on up to long stalks. They are in diameter and consist of about twelve to twenty five heavenly blue ray florets that surround many yellow disc florets. Three subspecies have been recognised, that differ in width of the leaves and the involucral bracts, the size of the heads and number of ray florets and in having glandular hairs. These can be found in coastal sands and inland areas in the Western Cape and Eastern Cape provinces of South Africa. Flower heads can be found from June till October.

Arabian Peninsula
The Arabian Peninsula (, , or , , ) or Arabia, is a peninsula in West Asia, situated north-east of Africa on the Arabian plate. At , comparable in size to India, the Arabian Peninsula is the largest peninsula in the world. Geographically, the Arabian Peninsula comprises Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE) and Yemen, as well as southern Iraq and Jordan. The largest of these is Saudi Arabia. In the Roman era, the Sinai Peninsula was also considered a part of Arabia. The Arabian Peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and south-west, the Persian Gulf and the Gulf of Oman to the north-east, the Levant and Mesopotamia to the north and the Arabian Sea and the Indian Ocean to the south-east. The peninsula plays a critical geopolitical role in the Arab world and globally due to its vast reserves of petroleum, oil and natural gas. Before the mod ...

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Sweden, Swedish Natural history, naturalist and an Apostles of Linnaeus, "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Italy and Asia, collecting and describing people and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Carl Linnaeus, Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern Taxonomy (biology), taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to P ...

William Aiton
William Aiton (17312 February 1793) was a Scotland, Scottish botanist. Aiton was born near Hamilton, Scotland, Hamilton. Having been regularly trained to the profession of a gardener, he travelled to London in 1754, and became assistant to Philip Miller, then superintendent of the Chelsea Physic Garden. In 1759 he was appointed director of the newly established Royal Botanic Gardens, Kew, botanical garden at Kew, where he remained until his death. He effected many improvements at the gardens, and in 1789 he published ''Hortus Kewensis'', a catalogue of the plants cultivated there. He is buried at nearby St. Anne's Church, Kew. A second and enlarged edition of the ''Hortus'' was brought out in 1810–1813 by his eldest son, William Townsend Aiton. Aiton is commemorated in the Specific epithet (botany), specific epithet ''aitonis''. In 1789, he classified the Sampaguita plant to the ''Jasmine, Jasminium'' genus and also named it as ''Arabian Jasmine'' because it was believed th ...

Michel Adanson
Michel Adanson (7 April 17273 August 1806) was an 18th-century French botanist and naturalist who traveled to Senegal to study flora and fauna. He proposed a "natural system" of taxonomy distinct from the binomial system forwarded by Linnaeus. Personal history Adanson was born at Aix-en-Provence. His family moved to Paris in 1730. After leaving the Collège Sainte-Barbe, he was employed in the cabinets of R. A. F. Réaumur and Bernard de Jussieu, as well as in the Jardin des Plantes, Paris.

Ageratum
''Ageratum'' () (whiteweed in the US) is a genus of 40 to 60 tropical and warm temperate flowering annuals and perennials from the family (biology), family Asteraceae, tribe (biology), tribe Eupatorieae. Most species are native plant, native to Central America and Mexico but four are native to the United States. They form tussocks or small hills. They grow to a height of . The opposite leaves are cordate or oval, hairy or tomentose. The margins are slightly toothed or serrate. The leaves form compact clusters. The fluffy flowers are lavender-blue, pink, lilac, or white, and spread in small compound umbels. They give small, dry fruits. Cultivation Ageratums are grown for their flowers, especially ''Ageratum houstonianum, A. houstonianum''. Most common ageratums, "Hawaii" for example, are a short when full grown. Tall ageratum are also available in seed catalogues. They are about in height with blue flowers. There is also a medium-height snowcapped variety, white top on bl ...

John Hill (botanist)
Sir John Hill (1714 – 22 November 1775) was an English composer, actor, author and botanist. He contributed to contemporary periodicals and engaged in literary battles with poets, playwrights and scientists. He is remembered for his illustrated botanical compendium ''The Vegetable System'', one of the first works to use the nomenclature of Carl Linnaeus. In recognition of his efforts, he was created a knight of the Order of Vasa in 1774 by Gustav III of Sweden and thereafter called himself Sir John Hill. Biography John Hill was the son of the Rev. Theophilus Hill and is believed to have been born in Peterborough: he was baptised on 17 November 1714 at St John the Baptist Church in that city.O'Connor 2022. He was apprenticed to an apothecary and on the completion of his apprenticeship he set up in a small shop in St Martin's Lane, Westminster. He also travelled over the country in search of rare herbs, with a view to publishing a '' hortus siccus'', but the plan failed. H ...

Validly Published Name
In botanical nomenclature, a validly published name is a name that meets the requirements in the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICN'') for valid publication. Valid publication of a name represents the minimum requirements for a botanical name to exist: terms that appear to be names but have not been validly published are referred to in the ''ICN'' as "designations". A validly published name may not satisfy all the requirements to be '' legitimate''. It is also not necessarily the correct name for a particular taxon and rank. Names that are not valid by ICN standards (''nomen invalidum'', ''nom. inval.'') are sometimes in use. This may occur when a taxonomist finds and recognises a taxon and thinks of a name, but delays publishing it in an adequate manner. A common reason to delay valid publication is that a taxonomist intends to write a ''magnum opus'' that provides an overview of the group, rather than a series of small papers. Another re ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called 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 (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". 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 ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
