Calycanthus
''Calycanthus'', called sweetshrub, is a genus of flowering plants in the family Calycanthaceae. The genus includes two to four species depending on taxonomic interpretation; three are accepted by most 21st century sources. Description ''Calycanthus'' plants are deciduous shrubs, growing to tall. The leaves are opposite and undivided. The plants are aromatic. The flowers are typical of the family Calycanthaceae in lacking distinct sepals and petals, but instead having spirals of tepals. Flowers are produced from spring onwards, until October in the case of ''C. occidentalis''. The flowers of the two North American species are scented, across, with numerous dark red to burgundy to purplish brown tepals. ''C. chinensis'' has broader tepals, the outer ones white flushed with pink, the inner ones mostly yellow with purple marks at the base. The fruit is an elliptical dry capsule, containing numerous seeds. ''C. floridus'' and ''C. occidentalis'' are pollinated by ...

Calycanthus Chinensis
''Calycanthus chinensis'', known as Chinese sweetshrub, is a species of flowering plant in the family Calycanthaceae, native to Southeast China. It was first given a valid scientific name in 1964. It is cultivated as an ornamental flowering shrub, and has been hybridized with two other species in the genus ''Calycanthus'' to combine its larger and broader tepalled flowers with their scented and more colourful ones. It has been treated as the only species in the genus ''Sinocalycanthus''. Description ''Calycanthus chinensis'' is a deciduous shrub or small tree up to high and the same across. Older twigs are hairless and have greyish or greyish-brown bark. The leaves are aromatic and arranged in an opposite fashion. The leaf petiole (stalk) is about long. The leaf blade is variable in shape but broadly ovate, long by wide. The base of the leaf petiole hides the lateral buds. In its original habitat in China, it flowers in May. The nodding flowers are terminal, about across, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calycanthus Floridus
''Calycanthus floridus'', or commonly known as the eastern sweetshrub, Carolina all spice, or spice bush, is a species of flowering shrub in the family Calycanthaceae. It is identifiable by its dark red flowers and fragrant scent. It is non-invasive and is found in the Southeastern United States region. The Nature Conservancy considers its conservation status to be G5, indicating it is at low risk of extinction. Description ''Calycanthus floridus'' is a shrub that grows to be around tall. Its leaves are a dark green with a pale underside. They are ovate or elliptical in shape and grow to be about 6 inches in length. The leaves are simple, entire, and arranged oppositely along the stem. The flowers are solitary, featuring a reddish brown to reddish purple color when they bloom in spring. They are aromatic and so are the leaves when bruised. The flowers have a hypanthium that is more than long. The shape of the flowers can be cylindrical, ellipsoid, pyriform, or globose. The fl ...

Calycanthaceae
The Calycanthaceae (sweetshrubs or spicebushes) are a small family of flowering plants in the order Laurales. The family contains three genera and only 10 known species , restricted to warm temperate and tropical regions: * '' Calycanthus'' (three species; western and southeastern North America and one species in eastern Asia) * ''Chimonanthus'' (six species; eastern Asia) * '' Idiospermum'' (one species; Queensland, Australia) They are aromatic, deciduous shrubs growing to 2–4 m tall, except for ''Idiospermum'', which is a large evergreen tree. The flowers are white to red, with spirally arranged tepals. DNA-based phylogenies indicate the Northern Hemisphere ''Calycanthus'' and ''Chimonanthus'' diverged from each other in the mid-Miocene, while the Australian ''Idiospermum'' had already diverged by the Upper Cretaceous and likely represents a remnant of a former Gondwanan distribution of Calycanthaceae that included South America, as indicated by the occurrence of Cretaceo ...

Idiospermum
''Idiospermum'' is a genus containing a single species of tree, ''Idiospermum australiense'', found in Australian tropical rainforests. The species represents one of the earliest known lineages of flowering plants, dating back as far as 120 million years. It is found today only in the Daintree and Wet Tropics rainforests region of north-eastern Queensland. It is endemic to a very few locations in north-eastern Queensland (e.g. in Daintree National Park), in the very wet lowland parts of the forest, in groups of 10–100 trees together (rather than scattered individuals). Common names include ribbonwood and idiot fruit. Description Ribbonwood trees grow naturally in their wet tropical rainforest habitats as evergreens up to about tall and about in diameter at breast height (DBH). The simple leaves grow singly, in pairs or in whorls of 3–4, each one measuring about long and wide. The flowers measure in diameter, with all floral organs spirally arranged. The tepals are initi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chimonanthus Praecox
''Chimonanthus praecox'', also known as wintersweet and Japanese allspice, is a species of flowering plant in the genus ''Chimonanthus'' of the family Calycanthaceae, native to China. The plant is known as ''làméi'' () in Chinese. The plant is also grown in Iran, where it is called ''gol-e yakh'' () or "ice flower" in Persian. It is a vigorous deciduous shrub growing to tall with an erect trunk and leaves long and broad. Its strongly scented pendant flowers, produced in winter (between November and March in UK,) on bare stems, have 15-21 yellow or pale green-yellow, tepals, the inner ones usually with purplish red pigments.

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Ear ...

Chimonanthus
''Chimonanthus'' is a genus of flowering plants in the family Calycanthaceae, native to China, but is also cultivated elsewhere in Asia, including Iran. The genus includes three to six species depending on taxonomic interpretation; six are accepted by the ''Flora of China''. The name means winter flower in Greek. Description They are deciduous or evergreen shrubs growing to 2–13 m tall. The leaves are opposite, entire, 7–20 cm long and 3–7 cm broad. The flowers are 2–3 cm wide, with numerous spirally-arranged yellow or white tepals; they are strongly scented, and produced in late winter or early spring before the new leaves. The fruit is an elliptic dry capsule 3–4 cm long. Species , ''Flora of China'' accepts the following species: *''Chimonanthus campanulatus'' R.H. Chang & C.S. Ding *''Chimonanthus grammatus'' M.C.

Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In ...

Extant Taxon
Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, '' recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The moose (''Alces alces'') is an extant species, and the dodo (''Raphus cucullatus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species ("Lazarus species"), or if previously-known extant species are reclassified as members of the taxon. Most biologists, zoologists, and botanists are in practice neontologists, and the term neontologist is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images.
