Pentaglottis
''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’'', ...

Boraginaceae
Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees and herbs in 146, to 156 genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system it was included in Lamiales, but it is now clear that it is no more similar to the other families in this order than they are to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae in eleven distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petiol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boraginoideae
Boraginoideae is a subfamily of the plant family Boraginaceae ', with about 42 genera. That family is defined in a much broader sense (Boraginaceae ') in the Angiosperm Phylogeny Group (APG) system of classification for flowering plants. The APG has not specified any subfamilial structure within Boraginaceae ''s.l.'' Taxonomy Some taxonomists placed the genera ''Codon'' and '' Wellstedia'' in Boraginoideae. Others place one or both of these in separate, monogeneric subfamilies. ''Codon'' was long regarded as an odd member of Hydrophylloideae, but in 1998, a molecular phylogenetic study suggested that it is closer to Boraginoideae. Neither is included n more modern classifications. Some authors proposed a revision of earlier APG systems, in which Boraginaceae had been included as an unplaced family (i.e. not included in a specified order) within the lamiid clade of eudicots. In that system. Boraginaceae was defined broadly (Boraginaceae ''sensu lato'' or ''s.l.''). Instead the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcicole
A calcicole, calciphyte or calciphile is a plant that thrives in lime rich soil. The word is derived from the Latin 'to dwell on chalk'. Under acidic conditions, aluminium becomes more soluble and phosphate less. As a consequence, calcicoles grown on acidic soils often develop the symptoms of aluminium toxicity, i.e. necrosis, and phosphate deficiency, i.e. anthocyanosis (reddening of the leaves) and stunting. A plant that thrives in acid soils is known as a calcifuge. A plant thriving on sand (which may be acidic or calcic) is termed psammophilic or arenaceous (see also arenite). Examples of calcicole plants * Ash trees (''Fraxinus'' spp.) * Honeysuckle (''Lonicera'') * ''Buddleja'' * Lilac (''Syringa'') * Beet * ''Clematis'' * ''Sanguisorba minor'' * Some European orchids * Some succulent plants genera ''Sansevieria'' and ''Titanopsis'' or cacti genus ''Thelocactus ''Thelocactus'' is a genus of flowering plants in the cactus family Cactaceae.

Alkanna Tinctoria
''Alkanna tinctoria'', the dyer's alkanet or simply alkanet, is a herbaceous flowering plant in the borage family Boraginaceae. Its roots are used to produce a red dye. The plant is also known as dyers' bugloss, orchanet, Spanish bugloss, or Languedoc bugloss. It is native to the Mediterranean region. ''A. tinctoria'' has 30 chromosomes and is regarded as a dysploid at the tetraploid level (4x + 2). ''A. tinctoria'' has a bright blue flower. The plant has a root of blackish appearance externally, but blue-red inside, with a whitish core. The root produces a fine red colouring material, which has been used as a dye in the Mediterranean region since antiquity. The dyestuff in its roots is soluble in alcohol, ether, and the oils, but is insoluble in water. It is used to give colour to wines and alcoholic tinctures, to vegetable oils, and to varnishes. Powdered and mixed with oil, the alkanet root is used as a wood stain. When mixed into an oily environment, it imparts a crimson ...

Anchusa Officinalis
''Anchusa officinalis'', commonly known as the common bugloss or alkanet, is a plant species in the genus ''Anchusa''. The plant provides a great deal of nectar for pollinators. It was rated in the top 10 for most nectar production (nectar per unit cover per year) in a UK plants survey conducted by the AgriLand project which is supported by the UK Insect Pollinators Initiative.

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] |
British Isles
The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles, and over six thousand smaller islands."British Isles", ''Encyclopædia Britannica''. They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though they do not form part of the archipelago. The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the northwest of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The ...

Middle English
Middle English (abbreviated to ME) is a form of the English language that was spoken after the Norman conquest of 1066, until the late 15th century. The English language underwent distinct variations and developments following the Old English period. Scholarly opinion varies, but the ''Oxford English Dictionary'' specifies the period when Middle English was spoken as being from 1150 to 1500. This stage of the development of the English language roughly followed the High to the Late Middle Ages. Middle English saw significant changes to its vocabulary, grammar, pronunciation, and orthography. Writing conventions during the Middle English period varied widely. Examples of writing from this period that have survived show extensive regional variation. The more standardized Old English language became fragmented, localized, and was, for the most part, being improvised. By the end of the period (about 1470) and aided by the invention of the printing press by Johannes Gutenberg in 14 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Spanish
Old Spanish, also known as Old Castilian ( es, castellano antiguo; osp, romance castellano ), or Medieval Spanish ( es, español medieval), was originally a dialect of Vulgar Latin spoken in the former provinces of the Roman Empire that provided the root for the early form of the Spanish language that was spoken on the Iberian Peninsula from the 10th century until roughly the beginning of the 15th century, before a ''consonantal readjustment'' gave rise to the evolution of modern Spanish. The poem ('The Poem of the Cid'), published around 1200, is the best known and most extensive work of literature in Old Spanish. Phonology The phonological system of Old Spanish was quite similar to that of other medieval Romance languages. Sibilants Among the consonants, there were seven sibilants, including three sets of voiceless/voiced pairs: *Voiceless alveolar affricate : represented by before , , , and by before or *Voiced alveolar affricate : represented by *Voiceless apicoa ...

Henna
Henna is a dye prepared from the plant ''Lawsonia inermis'', also known as the henna tree, the mignonette tree, and the Egyptian privet, the sole species of the genus ''Lawsonia''. ''Henna'' can also refer to the temporary body art resulting from the staining of the skin from the dyes. After henna stains reach their peak color, they hold for a few days, then gradually wear off by way of exfoliation, typically within one to three weeks. Henna has been used since antiquity in ancient Egypt and Indian subcontinent to dye skin, hair and fingernails, as well as fabrics including silk, wool, and leather. Historically, henna was used in West Asia including the Arabian Peninsula and in Carthage, other parts of North Africa, West Africa, Central Africa, the Horn of Africa and the Indian subcontinent. The name "henna" is used in other skin and hair dyes, such as ''black henna'' and ''neutral henna'', neither of which is derived from the henna plant. Etymology The English name "henna ...
