Halogeton Sativus
''Halogeton sativus'' is a species of flowering plant in the family Amaranthaceae. It is native to Spain, Morocco and Algeria. Rich in salt, in the past it was cultivated to produce soda ash Sodium carbonate, , (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na2CO3 and its various hydrates.

Lepidoptera
Lepidoptera ( ) is an order (biology), order of insects that includes butterfly, butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 Family (biology), families and 46 Taxonomic rank, superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most wikt:speciose, speciose orders, along with the Hymenoptera, fly, Diptera, and beetle, Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halophytes
A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs and seashores. The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'. Halophytes have different anatomy, physiology and biochemistry than glycophytes.Physiology of halophytes, T. J. FLOWERS, Plant and Soil 89, 41-56 (1985) An example of a halophyte is the salt marsh grass ''Spartina alterniflora'' (smooth cordgrass). Relatively few plant species are halophytes—perhaps only 2% of all plant species. Information about many of the earth's halophytes can be found in thehalophdatabase. The large majority of plant species are glycophytes, which are not salt-tolerant and are damaged fairly easily by high salinity. Classification Halophytes can be classified in many ways. According to Stocker (1933), it is mainly of 3 kind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coleophora
''Coleophora'' is a very large genus of moths of the family Coleophoridae. It contains some 1,350 described species. The genus is represented on all continents, but the majority are found in the Nearctic and Palaearctic regions. Many authors have tried splitting the genus into numerous smaller ones, but most of these have not become widely accepted. As with most members of the family, the larvae initially feed on the seeds, flowers or leaves of the host plant, but when larger, they feed externally and construct distinctive protective silken cases, often incorporating plant material. Many species have specific host plants; discarded larval cases are often scattered thickly on affected plants. Technical description For terms see External morphology of Lepidoptera Antennae 4/5, porrected in repose, often thickened with scales towards base, in male simple, basal joint long, usually with rough scales or projecting tuft.

Nutmeg (moth)
The nutmeg (''Hadula trifolii'' or ''Anarta trifolii''), also known as the clover cutworm, is a moth of the family Noctuidae. Distribution It is found in the Western Palearctic (western Europe, Tunisia, Iran), Niger, and Quebec in North America. In the north of its European range it is a summer Insect migration, migrant, not being able to survive the cold winters. Description This is a small to medium (wingspan 33–39 mm) species with cryptically coloured forewings, varying from light to dark brown, sometimes with a reddish tinge. The most characteristic feature is a distinctively "W"-shaped, white subterminal line. This feature is seen on some other noctuids, but usually much larger species. The hindwings are grey or buff, darker towards the Glossary of entomology terms, termen, and marked with dark veins.

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Carl Anton Von Meyer
Carl Anton von Meyer (in Russian: Карл Анто́нович фон Ме́йер, ''Karl Antonovich von Meyer'') (1 April 1795 – 24 February 1855) was a German, Russified botanist and explorer. Meyer was born in Vitebsk. He received his education at the University of Dorpat (1813-14) as a student of Karl Friedrich von Ledebour, with whom he later embarked on a scientific journey to the Crimea (1818). In 1826, with Ledebour and Alexander G. von Bunge, he took part in an expedition to the Altay Mountains and the Kirghiz Steppe (Kazakhstan). Plants collected on the trip formed the basis of "Flora Altaica" (four volumes issued between 1829 and 1833).JSTOR Global Plants JSTOR Global Plants] (biography) In 1835 he began work as a botanist for the [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium Oxalate
Sodium oxalate, or disodium oxalate, is the sodium salt of oxalic acid with the formula Na2C2O4. It is a white, crystalline, odorless solid, that decomposes above 290 °C. Disodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate (KMnO4) solutions. The mineral form of sodium oxalate is natroxalate. It is only very rarely found and restricted to extremely sodic conditions of ultra-alkaline pegmatites. Preparation Sodium oxalate can be prepared through the neutralization of oxalic acid with sodium hydroxide (NaOH) in a 1:2 acid-to-base molar ratio. Evaporation yields the anhydrous oxalateH. W.
