Triumfetta Rhomboidea
''Triumfetta rhomboidea'', commonly known as diamond burbark or Chinese bur, is a shrub that is extensively naturalised in tropical regions. It is thought that to have come to Australia from China. Its bark—sometimes called burbark--makes a kind of jute Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. It is produced from flowering plants in the genus ''Corchorus'', which is in the mallow family Malvaceae. The primary source of the fiber is ''Corchorus olit .... The taxon was first formally described in 1760 by botanist Nikolaus von Jacquin. Description Various sources give the number of stamens as being between 8 and 15. The fruit is round to slightly ovoid and about in diameter with smooth spines which are about long. The stems are covered in star-shaped ( stellate) hairs. Its embryology was described by Venkata Rao in 1952. References {{Taxonbar, from=Q10898699 Grewioideae Flora naturalised in Australia Taxa named by N ...

Kerala
Kerala ( ; ) is a state on the Malabar Coast of India. It was formed on 1 November 1956, following the passage of the States Reorganisation Act, by combining Malayalam-speaking regions of the erstwhile regions of Cochin, Malabar, South Canara, and Thiruvithamkoor. Spread over , Kerala is the 21st largest Indian state by area. It is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Lakshadweep Sea to the west. With 33 million inhabitants as per the 2011 census, Kerala is the 13th-largest Indian state by population. It is divided into 14 districts with the capital being Thiruvananthapuram. Malayalam is the most widely spoken language and is also the official language of the state. The Chera dynasty was the first prominent kingdom based in Kerala. The Ay kingdom in the deep south and the Ezhimala kingdom in the north formed the other kingdoms in the early years of the Common Era (CE). The region had been a prominent spic ...

Jute
Jute is a long, soft, shiny bast fiber that can be spun into coarse, strong threads. It is produced from flowering plants in the genus ''Corchorus'', which is in the mallow family Malvaceae. The primary source of the fiber is ''Corchorus olitorius'', but such fiber is considered inferior to that derived from ''Corchorus capsularis''. "Jute" is the name of the plant or fiber used to make burlap, hessian, or gunny cloth. Jute is one of the most affordable natural fibers and second only to cotton in the amount produced and variety of uses. Jute fibers are composed primarily of plant materials cellulose and lignin. Jute fiber falls into the bast fiber category (fiber collected from bast, the phloem of the plant, sometimes called the "skin") along with kenaf, industrial hemp, flax ( linen), ramie, etc. The industrial term for jute fiber is ''raw jute''. The fibers are off-white to brown and 1–4 meters (3–13 feet) long. Jute is also called the "golden fiber" for its color an ...

Nikolaus Joseph Von Jacquin
Nikolaus Joseph Freiherr von Jacquin (16 February 172726 October 1817) was a scientist who studied medicine, chemistry and botany. Biography Born in Leiden in the Netherlands, he studied medicine at Leiden University, then moved first to Paris and afterward to Vienna. In 1752, he studied under Gerard van Swieten in Vienna. Between 1755 and 1759, Jacquin was sent to the West Indies, Central America, Venezuela and New Granada by Francis I to collect plants for the Schönbrunn Palace, and amassed a large collection of animal, plant and mineral samples. In 1797, Alexander von Humboldt profited from studying these collections and conversing with Jacquin in preparation of his own journey to the Americas. In 1763, Jacquin became professor of chemistry and mineralogy at the Bergakademie Schemnitz (now Banská Štiavnica in Slovakia). In 1768, he was appointed Professor of Botany and Chemistry and became director of the botanical gardens of the University of Vienna. For his work ...

Australian Plant Name Index
The Australian Plant Name Index (APNI) is an online database of all published names of Australian vascular plants. It covers all names, whether current names, synonyms or invalid names. It includes bibliographic and typification details, information from the Australian Plant Census including distribution by state, links to other resources such as specimen collection maps and plant photographs, and the facility for notes and comments on other aspects. History Originally the brainchild of Nancy Tyson Burbidge, it began as a four-volume printed work consisting of 3,055 pages, and containing over 60,000 plant names. Compiled by Arthur Chapman, it was part of the Australian Biological Resources Study (ABRS). In 1991 it was made available as an online database, and handed over to the Australian National Botanic Gardens. Two years later, responsibility for its maintenance was given to the newly formed Centre for Plant Biodiversity Research. Scope Recognised by Australian herbaria as the ...

Trichomes
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chellapilla Venkata Rao
Chellapilla Venkata Rao (1910–1971) was an Indian botanist. Education He was awarded his PhD from the University of Tasmania in 1957 with a thesis entitled ''Cytotaxonomic studies in the Proteaceae''. Academic appointments He worked in the Department of Botany, Andhra University, Waltair, from 1948 to 1967. During this period he worked for three years on the Palmaceae as a senior post-doctoral fellow of the National Institute of Science of India.

Grewioideae
Grewioideae is a subfamily of the family Malvaceae and was first described by Hochreutiner. The group is named after its type genus, ''Grewia'', which is named for the English scientist Nehemiah Grew (1641-1712). It contains a number of genera that were previously placed in the defunct family Tiliaceae. Description Within the Malvaceae, this subfamily has its inflorescences opposite the leaves, the corollas are usually clawed, and there is a nectar-bearing hair carpet at the base of the petals and there are numerous dithecal stamens. The fruit is fleshy or capsular with spines, and the seeds are winged. The group is thought to have originated about 42 (± 15) million years ago. Taxonomy Ulrike Brunken & Alexandra Muellner divide the Grewioideae into two clades, the Grewia clade, Grewieae Endl. and the Apeiba clade, Apeibeae Benth., on the basis of morphological and molecular evidence. Tribes and genera The subfamily includes the following genera - accepted by Bayer & K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Naturalised In Australia
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
