Oxalis Articulata
Flowers ''Oxalis articulata'', known as pink-sorrel, pink wood sorrel, windowbox wood-sorrel, Chari amilo (Nepal), sourgrass, Netho (khatta) saag (India) is a perennial plant species in the genus ''Oxalis'' native to temperate South America. It has been introduced in Europe in gardens and is now naturalized in these areas. The plant is susceptible to rust (disease due to the fungus '' Puccinia oxalidis'').

Marie Jules César Savigny
Marie Jules César Lelorgne de Savigny (; 5 April 1777 – 5 October 1851) was a French zoologist. Savigny was born at Provins. In 1798 he travelled to Egypt with the Emperor Napoleon as part of the French scientific expedition to that country, and contributed to the publication of the findings of the expedition in 1809 (''Description de l'Égypte''; published more fully in 1822). He wrote about the fauna in the Mediterranean Sea and the Red Sea. He is also known for proposing a theory that the mouth-parts of insects are homologous with locomotory organs (e.g. legs). Education and travel to Egypt At age 16, Savigny traveled from his home of Provins, in the department of Seine et Marne, to Paris to finish his studies. Being very interested in botany, he worked at the ''Muséum national d'histoire naturelle'' with Jean-Baptiste Lamarck and Georges Cuvier. Cuvier suggested to Napoleon that the 21-year-old Savigny should follow him as zoologist to Egypt. Savigny became responsible ...

Oxalis
''Oxalis'' ( (American English) or (British English)) is a large genus of flowering plants in the wood-sorrel family Oxalidaceae, comprising over 550 species. The genus occurs throughout most of the world, except for the Polar region, polar areas; species diversity is particularly rich in tropical Brazil, Mexico, and South Africa. Many of the species are known as wood sorrels (sometimes written "woodsorrels" or "wood-sorrels") as they have an acidic taste reminiscent of the sorrel proper (''Rumex acetosa''), which is only distantly related. Some species are called yellow sorrels or pink sorrels after the color of their flowers instead. Other species are colloquially known as false shamrocks, and some called sourgrasses. For the genus as a whole, the term oxalises is also used. Description and ecology These plants are annual plant, annual or perennial plant, perennial. The leaves are divided into three to ten or more obovate and top-notched leaflets, arranged palmately with all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puccinia Oxalidis
''Puccinia oxalidis'' is a fungus species in the genus ''Puccinia''. This species is a causal agent of rust on plants in the genus ''Oxalis'', such as ''Oxalis articulata''. The disease appears as yellow dots on the reverse of the leaves. The aecial An aecium (plural aecia) is a specialised reproductive structure found in some plant pathogenic rust fungi that produce aeciospores. Aecia may also be referred to as "cluster cups". The term aecidium (plural aecidia) is used interchangeably but i ... stage can be found on '' Berberis repens''.Aecial Stage of Puccinia oxalidis. W. H. Long and R. M.

Jharkhand
Jharkhand (; ; ) is a state in eastern India. The state shares its border with the states of West Bengal to the east, Chhattisgarh to the west, Uttar Pradesh to the northwest, Bihar to the north and Odisha to the south. It has an area of . It is the 15th largest state by area, and the 14th largest by population. Hindi is the official language of the state. The city of Ranchi is its capital and Dumka its sub-capital. The state is known for its waterfalls, hills and holy places; Baidyanath Dham, Parasnath, Dewri and Rajrappa are major religious sites. The state was formed on 15 November 2000, after carving out what was previously the southern half of Bihar. Jharkhand suffers from what is sometimes termed a resource curse: it accounts for more than 40% of the mineral resources of India, but 39.1% of its population is below the poverty line and 19.6% of children under five years of age are malnourished. Jharkhand is primarily rural, with about 24% of its population living in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groundcover
Groundcover or ground cover is any plant that grows over an area of ground. Groundcover provides protection of the topsoil from erosion and drought. In an ecosystem, the ground cover forms the layer of vegetation below the shrub layer known as the herbaceous layer. The most widespread ground covers are grasses of various types. In ecology, groundcover is a difficult subject to address because it is known by several different names and is classified in several different ways. The term groundcover could also be referring to “the herbaceous layer,” “regenerative layer", “ground flora” or even "step over." In agriculture, ground cover refers to anything that lies on top of the soil and protects it from erosion and inhibits weeds. It can be anything from a low layer of grasses to a plastic material. The term ''ground cover'' can also specifically refer to landscaping fabric which is like a breathable tarp that allows water and gas exchange. In gardening jargon, however, ...

Oxalis Tetraphylla
''Oxalis tetraphylla'' (often traded under its synonym ''O. deppei'') is a bulbous herbaceous perennial plant from Mexico. It is sometimes sold as lucky clover or shamrock (even if it isn't a clover). In the wild or feral state it is often called four-leaved wood-sorrel after its genus Oxalidaceae. Other English common names for this plant include Lucky Glover, Four-Leaf Sorrel, Four-Leaf Pink-Sorrel and others. It is sometimes called "the iron cross plant" or "oxalis iron cross" because the leaves loosely resemble the iron cross symbol, though this name is not a classic folk term and has fallen out of favour due to the bad political connotations associated with this symbol. It is in the same family as the common wood-sorrel (''Oxalis acetosella'') and has three wild variants: var. tetraphylla (autonym) distributed in the states of Veracruz, México, Morelos and Michoacán, var. mexicana native to Hidalgo and Guerrero regions and var. guerreroensis native to Oaxaca, Guerrero, Mic ...

Plants Described In 1798
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 ability ...

Flora Of Southern America
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. 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 first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
