Geraniums
''Pelargonium'' () is a genus of flowering plants that includes about 280 species of perennials, succulents, and shrubs, commonly called geraniums, pelargoniums, or storksbills. '' Geranium'' is also the botanical name and common name of a separate genus of related plants, also known as cranesbills. Both genera belong to the family Geraniaceae. Carl Linnaeus originally included all the species in one genus, ''Geranium'', and they were later separated into two genera by Charles Louis L'Héritier de Brutelle in 1789. While ''Geranium'' species are mostly temperate herbaceous plants, dying down in winter, ''Pelargonium'' species are evergreen perennials indigenous to warm temperate and tropical regions of the world, with many species in southern Africa. They are drought and heat tolerant, but can tolerate only minor frosts. Some species are extremely popular garden plants, grown as houseplants and bedding plants in temperate regions. They have a long flowering period, with flowers m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geraniaceae
Geraniaceae is a family of flowering plants placed in the order Geraniales. The family name is derived from the genus ''Geranium''. The family includes both the genus ''Geranium'' (the cranesbills, or true geraniums) and the garden plants called geraniums, which modern botany classifies as genus ''Pelargonium'', along with other related genera. The family comprises 830 species in five to seven genera. The largest genera are ''Geranium'' (430 species), ''Pelargonium'' (280 species) and ''Erodium'' (80 species). Description Geraniaceae are herbs or subshrubs. The ''Sarcocaulon'' are succulent, but other members of the family generally are not. Leaves are usually lobed or otherwise divided, sometimes peltate, opposite or alternate and usually have stipules. The flowers are generally regular, or symmetrical. They are hermaphroditic, actinomorphic (radially symmetrical, like in ''Geranium'') or slightly zygomorphic (with a bilateral symmetry, like in ''Pelargonium''). The calyx a ...

Geranium
''Geranium'' is a genus of 422 species of annual, biennial, and perennial plants that are commonly known as geraniums or cranesbills. They are found throughout the temperate regions of the world and the mountains of the tropics, but mostly in the eastern part of the Mediterranean region. The palmately cleft leaves are broadly circular in form. The flowers have five petals and are coloured white, pink, purple or blue, often with distinctive veining. Geraniums will grow in any soil as long as it is not waterlogged. Propagation is by semiripe cuttings in summer, by seed, or by division in autumn or spring. Geraniums are eaten by the larvae of some Lepidoptera species including brown-tail, ghost moth, and mouse moth. At least several species of ''Geranium'' are gynodioecious. The species ''Geranium viscosissimum'' (sticky geranium) is considered to be protocarnivorous. Name The genus name is derived from the Greek (''géranos'') or (''geranós'') ' crane'.

Pelargonium Cucullatum
''Pelargonium cucullatum'' is a hairy, upright, branching, perennial shrub, of high, that has been assigned to the cranesbill family. It sprouts new stems from the underground rootstock and becomes woody at its base. It has alternately set, sometimes slightly succulent leaves crowded near the top of the branches, with leaf stalks and flat to hood-shaped leaf blades, with a rounded broad triangular to kidney-shaped outline of about long and wide, often somewhat incised, the margin with irregular teeth. The white to purplish red, 5-merous, somewhat mirror symmetrical flowers grow in umbel-like clusters, and each contain mostly 7 fertile stamens and 3 infertile staminodes (best checked in the bud) of different length. ''P. cucullatum'' has been cultivated as a garden ornamental and house plant since the 17th century. It has been used to breed many modern pelargonium hybrids, notably the Regal pelargoniums. It is called hooded-leaf pelargonium or herba althaea in English and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperateness
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Succulents
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, such as '' Glottiphyllum semicyllindricum'' and '' Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equipped to s ...

Shrubs
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 five ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbaceous
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts of ...

Growth Forms
Plant life-form schemes constitute a way of classifying plants alternatively to the ordinary species-genus-family scientific classification. In colloquial speech, plants may be classified as trees, shrubs, herbs (forbs and graminoids), etc. The scientific use of life-form schemes emphasizes plant function in the ecosystem and that the same function or "adaptedness" to the environment may be achieved in a number of ways, i.e. plant species that are closely related phylogenetically may have widely different life-form, for example ''Adoxa'' and ''Sambucus'' are from the same family, but the former is a small herbaceous plant and the latter is a shrub or tree. Conversely, unrelated species may share a life-form through convergent evolution. While taxonomic classification is concerned with the production of natural classifications (being natural understood either in philosophical basis for pre-evolutionary thinking, or phylogenetically as non-polyphyletic), plant life form classificat ...

Crane (bird)
Cranes are a family, the Gruidae, of large, long-legged, and long-necked birds in the group Gruiformes. The 15 species of cranes are placed in three genera, ''Antigone'', ''Balearica'', and '' Grus''. Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Cranes live on most continents, with the exception of Antarctica and South America. They are opportunistic feeders that change their diets according to the season and their own nutrient requirements. They eat a range of items from small rodents, eggs of birds, fish, amphibians, and insects to grain and berries. Cranes construct platform nests in shallow water, and typically lay two eggs at a time. Both parents help to rear the young, which remain with them until the next breeding season. Some species and populations of cranes migrate over long distances; others do not migrate at all. Cranes are solitary during the breeding season, occurring in pairs, but during the nonbreeding se ...

Dillenius
Johann Jacob Dillen Dillenius (1684 – 2 April 1747) was a German botanist. He is known for his ''Hortus Elthamensis'' ("Eltham Garden") on the rare plants around Eltham, London, and for his ''Historia muscorum'' ("History of Mosses"), a natural history of lower plants including mosses, liverworts, hornworts, lycopods, algae, lichens and fungi. Biography Dillenius was born at Darmstadt and was educated at the University of Giessen, earlier the family name had been changed from Dillen to Dillenius. In 1721, at the instance of the botanist William Sherard (1659–1728), he moved to England. In 1734 Dillenius was appointed Sherardian professor of botany at Oxford, in accordance with the will of Sherard, who at his death in 1728 left the university £3000 for the endowment of the chair, as well as his library and herbarium, all on the condition that Dillenius should be appointed the first professor. Dillenius died at Oxford, of apoplexy. His manuscripts, books and collections o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stork
Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family called Ciconiidae, and make up the order Ciconiiformes . Ciconiiformes previously included a number of other families, such as herons and ibises, but those families have been moved to other orders. Storks dwell in many regions and tend to live in drier habitats than the closely related herons, spoonbills and ibises; they also lack the powder down that those groups use to clean off fish slime. Bill-clattering is an important mode of communication at the nest. Many species are migratory. Most storks eat frogs, fish, insects, earthworms, small birds and small mammals. There are 19 living species of storks in six genera. Various terms are used to refer to groups of storks, two frequently used ones being a ''muster'' of storks and a ''phalanx'' of storks. Storks tend to use soaring, gliding flight, which conserves energy. Soaring requires thermal air currents. Ottomar Ans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
