Delonix Edulis
''Delonix edulis'' ( Malagasy:''Tara'') is a species of edible wild plant native to southwest Madagascar. The plant grows in semi-arid tropical zones with annual rainfall less than 400 mm, from sea level up to 100 meters elevation. The plant is classified in subfamily Caesalpinioideae of family Fabaceae. The scientific synonym ''Lemuropisum edule'' means ''edible lemur's pea''. The species is currently under investigation as a potential nut crop in Western Australia. Description Unarmed, multistemmed, much branched, spreading shrub up to 4–6 m tall, crown dense, branchlets sometimes spine-like. Leaves sparse, semi-persistent, paripinnate, with 1-4 pairs of oval to suborbicular leaflets, 3.5–6 mm wide. Inflorescence a raceme; flowers bisexual, with 4 white petals and 1 tinged yellow. Flowers are night-opening, with long stamens and a nectariferous upper petal shaped as a narrow tubular claw. Fruit pendent, subcylindric, depressed between the seeds, 20–30 c ...

Malagasy Language
Malagasy ( ; ; Sorabe: ) is an Austronesian languages, Austronesian language and dialect continuum spoken in Madagascar. The standard variety, called Official Malagasy, is one of the official languages of Madagascar, alongside French language, French. Malagasy is the westernmost Austronesian language, brought to Madagascar with the settlement of Austronesian peoples, Austronesian speakers from the Sunda Islands (about 7,300 kilometres or 4,500 miles away) around the 5th century AD or perhaps between the 7th and 13th centuries. The Malagasy language is one of the Barito languages and is most closely related to the Maʼanyan language, still spoken on Borneo. Malagasy also includes numerous Malay language, Malay loanwords, from the time of the early Austronesian settlement and trading between Madagascar and the Sunda Islands. After , Malagasy incorporated numerous Bantu languages, Bantu and Arabic language, Arabic loanwords brought over by traders and new settlers. Malagasy is spok ...

Carbohydrate
A carbohydrate () is a biomolecule composed of carbon (C), hydrogen (H), and oxygen (O) atoms. The typical hydrogen-to-oxygen atomic ratio is 2:1, analogous to that of water, and is represented by the empirical formula (where ''m'' and ''n'' may differ). This formula does not imply direct covalent bonding between hydrogen and oxygen atoms; for example, in , hydrogen is covalently bonded to carbon, not oxygen. While the 2:1 hydrogen-to-oxygen ratio is characteristic of many carbohydrates, exceptions exist. For instance, uronic acids and deoxy-sugars like fucose deviate from this precise stoichiometric definition. Conversely, some compounds conforming to this definition, such as formaldehyde and acetic acid, are not classified as carbohydrates. The term is predominantly used in biochemistry, functioning as a synonym for saccharide (), a group that includes sugars, starch, and cellulose. The saccharides are divided into four chemical groups: monosaccharides, disaccharides, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Joseph Marie Henry Alfred Perrier De La Bâthie
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 The Madagascar Spiny Thickets
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was ...

Plants Described In 1938
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 other gymnosperm ...

Delonix
''Delonix'' is a genus of flowering plants in the family Fabaceae, subfamily Caesalpinioideae. It contains trees that are native to Madagascar and East Africa. By far the best known species is the Royal Poinciana ('' D. regia''). The name of the genus is derived from the Greek words δηλος (''delos''), meaning "evident," and ονυξ (''onyx''), meaning "claw," referring to the petal Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corol ...s. The common name, poinciana, comes from a former genus of the same name in which the members of the current genus ''Delonix'' were classified along with plants now placed in the genus '' Caesalpinia''. Species 12 species are accepted: Use These plants (collectively known as or ) release brown resin lumps that can be dissolved to make glue, ...

Endemic Flora Of Madagascar
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology Conservation biology is the study of the conservation of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an i ... for measuring biodiversity in a particular place and evaluating t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chymotrypsin
Chymotrypsin (, chymotrypsins A and B, alpha-chymar ophth, avazyme, chymar, chymotest, enzeon, quimar, quimotrase, alpha-chymar, alpha-chymotrypsin A, alpha-chymotrypsin) is a digestive enzyme component of pancreatic juice acting in the duodenum, where it performs proteolysis, the breakdown of proteins and polypeptides. Chymotrypsin preferentially cleaves peptide amide bonds where the side chain of the amino acid N-terminal to the scissile amide bond (the P1 position) is a large hydrophobic amino acid ( tyrosine, tryptophan, and phenylalanine). These amino acids contain an aromatic ring in their side chain that fits into a hydrophobic pocket (the S1 position) of the enzyme. It is activated in the presence of trypsin. The hydrophobic and shape complementarity between the peptide substrate P1 side chain and the enzyme S1 binding cavity accounts for the substrate specificity of this enzyme. Chymotrypsin also hydrolyzes other amide bonds in peptides at slower rates, particularly th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cordeauxia Edulis
''Cordeauxia edulis'' is a plant in the family ''Fabaceae'' and the sole species in the genus ''Cordeauxia''. Known by the common name yeheb bush, it is one of the economically most important wild plants of the Horn of Africa, but it is little known outside of its distribution area. It is a multipurpose plant, which allows the survival of nomads by providing them with seeds. Further, the bush serves forage for livestock, firewood and dye. Its wild population is currently declining. Because it is potentially valuable for other hot, dry regions as a resource for food and fodder, it is recommended to take measures against its extinction. Taxonomy ''Cordeauxia edulis'' is a leguminous plant (Fabaceae) from the genus ''Cordeauxia''. The genus ''Cordeauxia'' is in subfamily Caesalpinioideae and tribe Caesalpinieae, and is closely related to the genera ''Caesalpinia'' and '' Stuhlmannia''. There are at least two varieties of the species ''C. edulis'': Moqley and Suley. Moqley has smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pep ...

Cashew
Cashew is the common name of a tropical evergreen tree ''Anacardium occidentale'', in the family Anacardiaceae. It is native to South America and is the source of the cashew nut and the cashew apple, an accessory fruit. The tree can grow as tall as , but the dwarf cultivars, growing up to , prove more profitable, with earlier maturity and greater yields. The cashew nut is edible and is eaten on its own as a snack, used in recipes, or processed into cashew cheese or cashew butter. The nut is often simply called a 'cashew'. The cashew apple is a light reddish to yellow fruit, whose pulp and juice can be processed into a sweet, astringent fruit drink or fermented and distilled into liquor. In 2023, 3.9 million tons of cashew nuts were harvested globally, led by the Ivory Coast and India. In addition to the nut and fruit, the shell yields derivatives used in lubricants, waterproofing, and paints. Description The cashew tree is large and evergreen, growing to tall, with a s ...

Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic.
