Saxifraga Flagellaris
''Saxifraga flagellaris'', the whiplash saxifrage or flagellate saxifrage, is a plant native all over the Eurasian Arctic Coast, Siberia, Far East, Caucasus and some areas of northern Rocky Mountains. It is not very common. It is also known as spider saxifrage or "spider plant", though the latter name more commonly refers to the unrelated ''Chlorophytum comosum'' (Agavaceae). The broadsepal saxifrage ('' S. platysepala'') was formerly included in the present species, then made a separate species, and later again made a subspecies, Saxifraga flagellaris ssp. platysepala—broadsepal saxifrage (http://www.cbif.gc.ca/pls/itisca/next?v_tsn=24270&taxa=&p_format=&p_ifx=&p_lang=). The species found in Greenland, Svalbard, Alaska etc. is Saxifraga flagellaris ssp. platysepala—broadsepal saxifrage. The stems are single, erect and leafy, growing to 3–10 cm tall. The basal leaves in a dense rosette from which long, filiform runners radiate ending in a small, rooting offset; they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Ludwig Willdenow
Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant Taxonomy (biology), taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology. Biography Willdenow was born in Berlin and studied medicine and botany at the University of Halle. After studying pharmaceutics at Wieglieb College, Langensalza and in medicine at Halle, he returned to Berlin to work at his father's pharmacy located in the Unter den Linden. His early interest in botany was kindled by his uncle Johann Gottlieb Gleditsch, J. G. Gleditsch and he started a herbarium collection in his teenage years. In 1794, he became a member of the Berlin Academy of Sciences. He was a director of the Botanica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaspar Maria Von Sternberg
Count Kaspar Maria von Sternberg (also: ''Caspar Maria'', ''Count Sternberg'', , ; 6 January 1761 – 20 December 1838) was a Bohemian aristocrat, theologian, mineralogist, geognost, entomologist and botanist. He is known as the "Father of Paleobotany". Early life and ancestry Born into one of the most prominent Bohemian noble families, he was the youngest child of Count Johann Nepomuk I von Sternberg (1713-1798) and his wife, Countess Maria Anna Josefa Kolowrat-Krakowsky (1726-1790).

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in great-circle distance, straight-line distance from the northernmost part of Western Canada, to New Mexico in the Southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of Rocky Mountain Trench, the Trench, or in the northeastern foothills of the Brooks Range/British Mountains that face the Beaufort Sea coasts between the Canning River (Alaska), Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque metropolitan area, Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountains, Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlorophytum Comosum
''Chlorophytum comosum'', usually called spider plant or common spider plant due to its spider-like look, also known as spider ivy, airplane plant, ribbon plant (a name it shares with ''Dracaena sanderiana''), and hen and chickens, is a species of evergreen Perennial plant, perennial flowering plant of the family Asparagaceae. It is native plant, native to Tropical Africa, tropical and Southern Africa but has become naturalized in other parts of the world, including Western Australia and Bangladesh., search for "Chlorophytum comosum" ''Chlorophytum comosum'' is easy to grow as a houseplant because of its resilience, but it can be sensitive to the fluoride in tap water, which commonly gives it "burnt tips". Variegation, Variegated forms are the most popular. Description ''Chlorophytum comosum'' grows to about tall, although as a hanging plant it can descend many feet. It has fleshy, Tuber#Root tubers, tuberous roots, each about long. The long narrow leaves reach a length of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agavaceae
Agavoideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales. It has previously been treated as a separate family, Agavaceae. The group includes many well-known desert and dry-zone types, such as the agaves and yuccas (including the Joshua tree). About 640 species are placed in around 23 genera; they are widespread in the tropical, subtropical, and warm temperate regions of the world. Description and uses Species may be succulent or not. In general, Agavoideae leaves occur as rosettes at the end of a woody stem, which may range from extremely short to tree-like heights, as in the Joshua tree. The leaves are parallel-veined, and usually appear long and pointed, often with a hardened spine on the end, and sometimes with additional spines along the margins. ''Agave'' species are used to make ''tequila, pulque,'' and '' mezcal'', while others are valued for their fibers. They are quite popular for xeriscaping, as many have showy flowers. ...

Leaf
A leaf (: leaves) is a principal appendage of the plant stem, stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the Shoot (botany), shoot system. In most leaves, the primary Photosynthesis, photosynthetic Tissue (biology), tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, Trichome, hairiness, the number of stomata (pores that intake and output gases), the amount and ...

Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil, but they can also be at the top of an otherwise naked branch or trunk. Their structure is an example of a Aerial stem modification, modified stem in which the internode (botany), internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of Gall, galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant family (taxonomy), families have varieties with rosette Morphology (biology), morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern ''Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eugen Warming
Johannes Eugenius Bülow Warming (3 November 1841 – 2 April 1924), known as Eugen Warming, was a Danish botanist and a main founding figure of the scientific discipline of ecology. Warming wrote the first textbook (1895) on plant ecology, taught the first university course in ecology and gave the concept its meaning and content. Scholar R. J. Goodland wrote in 1975: “''If one individual can be singled out to be honoured as the founder of ecology, Warming should gain precedence''”. Warming wrote a number of textbooks on botany, plant geography and ecology, which were translated to several languages and were immensely influential at their time and later. Most important were '' Plantesamfund'' and ''Haandbog i den systematiske Botanik''. Early life and family life Warming was born on the small Wadden Sea island of Mandø as the only child of Jens Warming (1797–1844), parish minister, and Anna Marie von Bülow af Plüskow (1801–1863). After the early death of his fathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxifraga
''Saxifraga'' is the largest genus in the family Saxifragaceae, containing about 473 species of holarctic perennial plants, known as saxifrages or rockfoils. The Latin word ''saxifraga'' means literally "stone-breaker", from Latin ' ("rock" or "stone") + ' ("to break"). It is usually thought to indicate a medicinal use for treatment of urinary calculi (known as kidney or bladder stones), rather than breaking rocks apart. Description Most saxifrages are small perennial, biennial (e.g. '' S. adscendens'') or annual (e.g. '' S. tridactylites'') herbaceous plants whose basal or cauline leaves grow close to the ground, often in a rosette. The leaves typically have a more or less incised margin; they may be succulent, needle-like and/or hairy, reducing evaporation. The inflorescence or single flower clusters rise above the main plant body on naked stalks. The small actinomorphic hermaphrodite flowers have five petals and sepals and are usually white, but red to yellow in some spe ...
