Lathyrus Cicera
''Lathyrus cicera'' is a species of wild pea known by the common names red pea, red vetchling and flatpod peavine. It is native to Europe, North Africa, and the Middle East, and it is known from other places as an introduced species. This is a hairless annual herb producing a slightly winged stem. The leaves are each made up of two leaflike linear leaflets long. They also bear branched, curling tendrils. The inflorescence holds a single pea flower wide which is a varying shade of red. The fruit is a hairless dehiscent legume pod. This is one pea species known to cause lathyrism Lathyrism is a condition caused by eating certain legumes of the genus ''Lathyrus''. There are three types of lathyrism: ''neurolathyrism'', ''osteolathyrism'', and ''angiolathyrism'', all of which are incurable, differing in their symptoms and ...; nevertheless, as ''cicerchia'' it figured among the comestibles enjoyed by the fortunate Milanese, listed at length by Bonvesin de la Riva in his "Marv ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist 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 the son of a curate and was born in Råshult, in the countryside of Småland, 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 the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lathyrus
''Lathyrus'' is a genus of flowering plants in the legume family Fabaceae, and contains approximately 160 species. Commonly known as peavines or vetchlings, they are native to temperate areas, with a breakdown of 52 species in Europe, 30 species in North America, 78 in Asia, 24 in tropical East Africa, and 24 in temperate South America. There are annual and perennial species which may be climbing or bushy. This genus has numerous sections, including ''Orobus'', which was once a separate genus. The genus has numerous synonyms, including ''Pisum'', the ancient Latin name for the pea.Gledhill, David (2008). "The Names of Plants". Cambridge University Press.

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 ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tendril
In botany, a tendril is a specialized Plant stem, stem, leaf or Petiole (botany), petiole with a thread-like shape used by climbing plants for support and attachment, as well as cellular invasion by parasitic plants such as ''Cuscuta''. There are many plants that have tendrils; including sweet peas, passionflower, grapes and the Chilean glory-flower. Tendrils respond to touch and to chemical factors by curling, twining, or adhering to suitable structures or hosts. Tendrils vary greatly in size from a few centimeters up to 27 inches (69 centimeters) for ''Nepenthes harryana''. The chestnut vine (''Tetrastigma voinierianum'') can have tendrils up to 20.5 inches (52 centimeters) in length. Normally there is only one simple or branched tendril at each node (see plant stem), but the aardvark cucumber (''Cucumis humifructus'') can have as many as eight. History The earliest and most comprehensive study of tendrils was Charles Darwin's monograph ''On the Movements and Habits of Climb ...

Inflorescence
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's Plant stem, stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis (Peduncle (botany), peduncle) and by the timing of its flowering (determinate and indeterminate). Morphology (biology), Morphologically, an inflorescence is the modified part of the Shoot (botany), shoot of spermatophyte, seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internode (botany), internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dehiscence (botany)
Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part. Structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay, digestion by herbivores, or predation to release the contents. A similar process to dehiscence occurs in some flower buds (e.g., '' Platycodon'', '' Fuchsia''), but this is rarely referred to as dehiscence unless circumscissile dehiscence is involved; anthesis is the usual term for the opening of flowers. Dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be caducous. Association with crop breeding Manipulation of dehiscence can improve crop yield since a trait that causes seed dispersal is a disadvantage for fa ...

Lathyrism
Lathyrism is a condition caused by eating certain legumes of the genus ''Lathyrus''. There are three types of lathyrism: ''neurolathyrism'', ''osteolathyrism'', and ''angiolathyrism'', all of which are incurable, differing in their symptoms and in the body tissues affected. Neurolathyrism is the type associated with the consumption of legumes in the genus ''Lathyrus'' that contain the toxin oxalyldiaminopropionic acid (ODAP). ODAP ingestion results in motor neuron death. The result is paralysis and muscle atrophy of the lower limbs. Osteolathyrism, a different type of lathyrism, affects the connective tissues, not the motor neurons. Osteolathyrism results from the ingestion of ''Lathyrus odoratus'' seeds (sweet peas), and is often referred to as odoratism. It is caused by a different toxin, beta-aminopropionitrile, which affects the linking of the subunits of collagen, a major structural protein found in connective tissue. A third type of lathyrism is angiolathyrism, which is sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonvesin De La Riva
Bonvesin da la Riva (; sometimes Italianized in spelling Bonvesino or Buonvicino; ) was an Italian Medieval writer and poet. Bonvesin was a notable Lombard poet and writer, giving one of the first known examples of the written Lombard language. He is often described as the "father" of the Lombard language. Biography A well-to-do Milanese lay member of the Ordine degli Umiliati (literally, "Order of the Humble Ones") Bonvesin was a teacher of (Latin) grammar in Legnano and in Milan. In 1291, he bought a house in the suburb of Porta Ticinese. There he dwelt and prospered, surviving two wives (Benghedice and Floramonte) and dying without issue between 1313 and 1315. In the interim, he had accumulated and preserved a comfortable capital, as we know from his two wills (of 1304 and 1313, respectively). In 1290, he loaned 200 lire (a denomination of much greater weight 700 years ago) to the Ospedale della Colombetta at a rate of 6 percent per annum to be received as an annuity by him ...

Plants Described In 1753
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants ( hornworts, liverworts, mosses, lycophytes, ferns, conifers and o ...

Taxa Named By Carl Linnaeus
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be Boundaries between the continents#Asia and Europe, separated from Asia by the Drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the waterway of the Bosporus, Bosporus Strait.
