Vicia Tenuifolia
''Vicia tenuifolia'', the fine-leaved vetch and cow vetch, as well as fodder vetch and bramble vetch, is a herbaceous perennial plant species in the family Fabaceae. This species grows widespread in Europe and some parts of both Asia and Africa. In some other areas it occurs as an introduced species. In few countries this edible vetch is used in both human and farm animals nutrition. Taxonomy ''Vicia tenuifolia'' was described by German botanist Albrecht Wilhelm Roth in his work Tentamen florae germanicae in 1788. Some taxonomists treat this species as a subspecies of '' Vicia cracca'', while most recognize it as its own species. There are a few recognized subspecies: * ''Vicia tenuifolia'' subsp. ''atroviolacea'' ( Bornm.) Greuter & Burdet * ''Vicia tenuifolia'' subsp. ''delmasii'' (Emb. & Maire) Dobignard * ''Vicia tenuifolia'' subsp. ''subalpina'' ( Grossh.) Zernov * ''Vicia tenuifolia'' subsp. ''tenuifolia'' * ''Vicia tenuifolia'' subsp. ''variabilis'' ( Freyn & Sint.) D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albrecht Wilhelm Roth
Albrecht Wilhelm Roth (6 January 1757 – 16 October 1834) was a physician and botanist born in Dötlingen, Germany. He studied medicine at the Universities of Halle and Erlangen, where he received his doctorate in 1778. After graduation, he practiced medicine in Dötlingen, and shortly afterwards relocated to Bremen-Vegesack. Roth is remembered for his influential scientific publications, particularly in the field of botany. His botanical research and writings came to the attention of Johann Wolfgang von Goethe (1749–1832), who recommended Roth to a position at the botanical institute at the University of Jena. Two of his better written works were ''Tentamen florae germanica'' (a treatise on German flora), and ''Novae plantarum species praesertim Indiae orientalis'' (a book of Indian flora). The latter work is primarily based on botanical specimens collected by Moravian missionary Benjamin Heyne (1770–1819). The botanical genus '' Rothia'' from the family Family (fro ...

Pinnately Compound
Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and in patterns of erosion or stream beds. The term derives from the Latin word ''pinna'' meaning "feather", "wing", or "fin". A similar concept is "pectination," which is a comb-like arrangement of parts (arising from one side of an axis only). Pinnation is commonly referred to in contrast to "palmation," in which the parts or structures radiate out from a common point. The terms "pinnation" and "pennation" are cognate, and although they are sometimes used distinctly, there is no consistent difference in the meaning or usage of the two words.Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Plants Botanically, pinnation is an arrangement of dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vicia Villosa
''Vicia villosa'', known as the hairy vetch, fodder vetch or winter vetch, is a plant native to some of Europe and western Asia. It is a legume, grown as a forage crop, fodder crop, cover crop, and green manure. Although non-native, it occurs in all US states and is considered invasive by some states, such as Alaska, Florida, Georgia, Kansas, Michigan, Minnesota, Oregon, and Washington state — as well as in Japan and some parts of Europe where it is not native. It is also found in most Canadian provinces. Hairy vetch is very similar to tufted vetch (''Vicia cracca''), the most noticeable difference being that tufted vetch has a smooth stem. Several subspecies are recognized: * ''Vicia villosa'' ssp. ''ambigua'' (Guss.) Kerguelen (= ssp. ''elegantissima'', ssp. ''pseudocracca'') * ''Vicia villosa'' ssp. ''eriocarpa'' (Hausskn.) P.W.Ball * ''Vicia villosa'' ssp. ''microphylla'' (d'Urv.) P.W.Ball * ''Vicia villosa'' ssp. ''varia'' (Host) Corb. (= ssp. ''dasycarpa'') * ''Vicia vil ...

Vicia Incana
''Vicia'' is a genus of over 240 species of flowering plants that are part of the legume family (Fabaceae), and which are commonly known as vetches. Member species are native to Europe, North America, South America, Asia and Africa. Some other genera of their subfamily Faboideae also have names containing "vetch", for example the vetchlings (''Lathyrus'') or the milk-vetches ('' Astragalus''). The broad bean ('' Vicia faba'') is sometimes separated in a monotypic genus ''Faba''; although not often used today, it is of historical importance in plant taxonomy as the namesake of the order Fabales, the Fabaceae and the Faboideae. The tribe Vicieae in which the vetches are placed is named after the genus' current name. Among the closest living relatives of vetches are the lentils ('' Lens'') and the true peas ('' Pisum''). Use by humans Bitter vetch ('' V. ervilia'') was one of the first domesticated crops. It was grown in the Near East about 9,500 years ago, starting perha ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica'') and radish (genus ''Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A compou ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Papilionaceous Flower
Papilionaceous flowers (from Latin: ''papilion'', a butterfly) are flowers with the characteristic irregular and butterfly-like corolla found in many, though not all, plants of the species-rich Faboideae subfamily of legumes. Tournefort suggested that the term ''Flores papilionacei'' originated with Valerius Cordus, who applied it to the flowers of the bean. Structure Corolla The flowers have a bilateral symmetry with the corolla consisting of five petals. A single, large, upper petal is known as the banner (also vexillum or standard petal). The semi-cylindrical base of the banner embraces and compresses two equal and smaller lateral wings (or alae). The wings in turn enclose a pair of small keel petals, that are situated somewhat lower than the wings, but are interior to them. They have concave sides and correspond with the shape of the wings. The two keel petals are fused at their bases or stuck together to form a boat-shaped structure that encloses the essential flower organs ...

Bilaterally Symmetrical
Symmetry in biology refers to the symmetry observed in organisms, including plants, animals, fungi, and bacteria. External symmetry can be easily seen by just looking at an organism. For example, take the face of a human being which has a plane of symmetry down its centre, or a pine cone with a clear symmetrical spiral pattern. Internal features can also show symmetry, for example the tubes in the human body (responsible for transporting gases, nutrients, and waste products) which are cylindrical and have several planes of symmetry. Biological symmetry can be thought of as a balanced distribution of duplicate body parts or shapes within the body of an organism. Importantly, unlike in mathematics, symmetry in biology is always approximate. For example, plant leaves – while considered symmetrical – rarely match up exactly when folded in half. Symmetry is one class of patterns in nature whereby there is near-repetition of the pattern element, either by reflection or rotation. ...

Entomophilous
Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns (honey guides) leading to rewards of pollen and nectar; they may also have an attractive scent which in some cases mimics insect pheromones. Insect pollinators such as bees have adaptations for their role, such as lapping or sucking mouthparts to take in nectar, and in some species also pollen baskets on their hind legs. This required the coevolution of insects and flowering plants in the development of pollination behaviour by the insects and pollination mechanisms by the flowers, benefiting both groups. Coevolution History The early spermatophytes (seed plants) were largely dependent on the wind to carry their pollen from one plant to another. Prior to the appearance of flowering plants some gymnospe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
