Anchusa Arvensis
''Anchusa arvensis'' is a plant species of the genus ''Anchusa''. Its common names include small bugloss and annual bugloss. Description This is a hairy annual herb which may reach half a meter in height. It bears small blue tubular flowers, four nutlets per flower, and one seed per nutlet. Leaves are very bristly and warty-looking, which differentiates it from similar species like '' Pentaglottis sempervirens'' and ''Myosotis arvensis''. Distribution and Habitat The plant is native to Europe, and is found elsewhere. ''Anchusa arvensis'' is found in arable field margins, sandy heaths A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler a ..., disturbed ground. In the UK it is a declining species with patchy distribution, however conservation status as of 2005 is least concern. ''Anc ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné 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". 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 the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anchusa
The genus ''Anchusa'' belongs to the borage family (Boraginaceae). It includes about 35 species found growing in Europe, North Africa, South Africa and Western Asia. They are introduced in the United States. They consist of annual plants, biennial plants and perennial plants with the general characteristics of the borage family. They are commonly herbaceous. The leaves are simple or undulate, covered with stiff hairs. The small radially symmetrical flowers are sapphire blue and retain their colour a long time. The plants show numerous flowers with five sepals, united at their bases, and five petals forming a narrow tube facing upwards. The flowers grow in several axillary cymes, simple or branched, or are clustered at the end. The flowers are much frequented by bees. The genus ''Anchusa'' is commonly used in trough or rock gardens. The roots of ''Anchusa'' (just like those of ''Alkanna'' and '' Lithospermum'') contain anchusin (or alkanet-red), a red-brown resinoid colouri ...

Nutlet
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible. In general usage and in a culinary sense, a wide variety of dry seeds are called nuts, but in a botanical context "nut" implies that the shell does not open to release the seed (indehiscent). Most seeds come from fruits that naturally free themselves from the shell, but this is not the case in nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary. The general and original usage of the term is less restrictive, and many nuts (in the culinary sense), such as almonds, pecans, pistachios, walnuts, and Brazil nuts, are not nuts in a botanical sense. Common usage of the term often refers to any hard-walled, edible kernel as a nut. Nuts are an energy-dense and nutrient-rich food source. Botanical definition A seed is the mature fertilised ovule of a plant; it consists of three parts, the embryo which will develop into ...

Pentaglottis Sempervirens
''Pentaglottis'' is a monotypic genus of flowering plants in the family Boraginaceae. It is represented by a single species, ''Pentaglottis sempervirens'', commonly known as the green alkanet, evergreen bugloss or alkanet, and is a bristly, perennial plant native to Western Europe. It grows to approximately 60 cm (24") to 90 cm (36"), usually in damp or shaded places and often close to buildings. It has brilliant blue flowers, and retains its green leaves through the winter. The plant has difficulty growing in acidic soil (it is calcicolous). The name "alkanet" is also used for dyer's bugloss (''Alkanna tinctoria'') and common bugloss (''Anchusa officinalis''). Green alkanet is an introduced species in the British Isles.http://www.nhm.ac.uk/fff-pcp/glob.pl?report=Flora&Flora. loraNo236800 The word "alkanet" derives from Middle English, from Old Spanish ''alcaneta'', diminutive of ''alcana'', "henna", from Medieval Latin ''alchanna'', from Arabic ''al-ḥinnā’'', ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. 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 is commonly considered to be Boundaries between the continents of Earth#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 waterways of the Turkish Straits.

Arable Land
Arable land (from the la, arabilis, "able to be ploughed") is any land capable of being ploughed and used to grow crops.''Oxford English Dictionary'', "arable, ''adj''. and ''n.''" Oxford University Press (Oxford), 2013. Alternatively, for the purposes of agricultural statistics, the term often has a more precise definition: A more concise definition appearing in the Eurostat glossary similarly refers to actual rather than potential uses: "land worked (ploughed or tilled) regularly, generally under a system of crop rotation". In Britain, arable land has traditionally been contrasted with pasturable land such as heaths, which could be used for sheep-rearing but not as farmland. Arable land area According to the Food and Agriculture Organization of the United Nations, in 2013, the world's arable land amounted to 1.407 billion hectares, out of a total of 4.924 billion hectares of land used for agriculture.

Heaths
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations across ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Described In 1753
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...
