Waltheria Virgata
''Waltheria virgata'' is a species of flowering plant in the mallow family, Malvaceae, that is found in the north of Western Australia, and in the Northern Territory. Description ''Waltheria virgata'' is an erect, much branched shrub growing from a height of 0.3 m to 1 m high, and up to 1 m wide. Its leaves and stems are thinly to densely covered in stellate (star-shaped) hairs. Its pink-purple flowers may be seen from April to May or July to October. Habitat It grows on red sand and stony soils, on plains, on rocky hills, and in stony creeks. Taxonomy and naming It was first described in 1917 by Alfred James Ewart & Isabel Clifton Cookson. There are no synonyms. The specific epithet, ''virgata'', derives from the Latin word, ''virga'', "a rod for beating", to give a Botanical Latin adjective describing the plant as having "straight slender not very flexible twigs". The genus name, ''Waltheria'', honours the German botanist Augustin Friedrich Walther. References Extern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malva
''Malva'' is a genus of herbaceous annual, biennial, and perennial plants in the family Malvaceae. It is one of several closely related genera in the family to bear the common English name mallow. The genus is widespread throughout the temperate, subtropical and tropical regions of Africa, Asia and Europe. The leaves are alternate, palmately lobed. The flowers are from 0.5–5 cm diameter, with five pink, lilac, purple or white petals. Etymology The word "mallow" is derived from Old English "mealwe", which was imported from Latin "malva", cognate with Ancient Greek μαλάχη (malakhē) meaning "mallow", both perhaps reflecting a Mediterranean term. The colour mauve was in 1859 named after the French name for this plant. Uses Ornamental plant Several species are widely grown as garden flowers. Very easily grown, short-lived perennials are often grown as ornamental plants. Food Many species are edible as leaf vegetables and commonly foraged in the West. Known ...

Malvaceae
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as '' Alcea'' (hollyhock), '' Malva'' (mallow), and ''Tilia'' (lime or linden tree). The largest genera in terms of number of species include ''Hibiscus'' (300 species), '' Sterculia'' (250 species), '' Dombeya'' (250 species), '' Pavonia'' (200 species) and '' Sida'' (200 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae ''sensu stricto'' comprise a very homogeneous and cladistically monophyletic group. Another major circumscription, Malvaceae '' sensu lato'', has been more recently defined on the basis that genetics studies have shown the commonly recognised families Bombacaceae, Tiliaceae, and Sterculiaceae, which have always been considered closely a ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616.

Northern Territory
The Northern Territory (commonly abbreviated as NT; formally the Northern Territory of Australia) is an Australian territory in the central and central northern regions of Australia. The Northern Territory shares its borders with Western Australia to the west ( 129th meridian east), South Australia to the south ( 26th parallel south), and Queensland to the east ( 138th meridian east). To the north, the territory looks out to the Timor Sea, the Arafura Sea and the Gulf of Carpentaria, including Western New Guinea and other islands of the Indonesian archipelago. The NT covers , making it the third-largest Australian federal division, and the 11th-largest country subdivision in the world. It is sparsely populated, with a population of only 249,000 – fewer than half as many people as in Tasmania. The largest population center is the capital city of Darwin. The archaeological history of the Northern Territory may have begun more than 60,000 years ago when humans first se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Latin
Botanical Latin is a technical language based on New Latin, used for descriptions of botanical taxa. Until 2012, International Code of Botanical Nomenclature mandated Botanical Latin to be used for the descriptions of most new taxa. It is still the only language other than English accepted for descriptions. The names of organisms governed by the Code also have forms based on Latin. Botanical Latin is primarily a written language. It includes taxon names derived from any language or even arbitrarily derived, and consequently there is no single consistent pronunciation system. When speakers of different languages use Botanical Latin in speech, they use pronunciations influenced by their own languages, or, notably in French, there may be variant spellings based on the Latin. There are at least two pronunciation systems used for Latin by English speakers. Neither system, however, works across the full spectrum of botanical names, because many non-Latin words, such as people's names, h ...

Augustin Friedrich Walther
Augustin Friedrich Walther (26 October 1688 – 12 October 1746) was a German anatomist, botanist and physician who was a native of Wittenberg. He was the son of theologian Michael Walther the Younger (1638–1692). In 1712 he earned his degree of philosophy from the University of Wittenberg, and in the following year received his medical doctorate from the University of Leipzig. At Leipzig he became a professor of anatomy (1728), pathology (1732) and therapy (1737). In 1730 he became director of the Leipzig Botanical Gardens, and in 1737 was rector at the university. Among his numerous writings was a 1735 botanical treatise called ''Designatio plantarum quas hortus AF Waltheri complectitur'', in which he provides descriptions of thousands of plant species from his private botanical garden. As a physician he made contributions in the fields of myology and angiology, and has several medical and anatomical terms named after him, including: * "Walther's dilator": An instrument u ...

Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen reco ...

Eudicots Of Western Australia
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non- magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.
