Ewartia Planchonii
''Ewartia planchonii'', commonly known as creeping cushionherb, is an endemic herb to alpine areas of Tasmania. ''E. planchonii'' is commonly found in the western highlands of Tasmania. The ''Ewartia'' genus is described as cushion plants/herbs due to the characteristic growth habits of low growing, highly compact mats which are made up of highly packed stems. These mats are slow-growing and are often located in soils that contain low nutrients. Description ''Ewartia planchonii'' is a sprawling herb which forms mat-like ground coverage over rocky alpine landscapes. Leaves are densely tufted, overlapping along the stem, obovately shaped and 3-6mm long. The leaves are also covered by soft hairs which whiten with age. Flowerheads are ovoid in shape and open up flat to 7-8mm long, brownish/ yellow and lack the usual petal-like bracts. Flowering occurs over the summer months to increase chances of pollination.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Alfred James Ewart
Alfred James Ewart, FRS (12 February 1872 – 12 September 1937) was an English-Australian botanist. Early life and education Ewart was born in Toxteth Park, Liverpool, England, second son of Edmund Brown Ewart, B.A. and his wife, Martha ''née'' Williams. He was educated at the Liverpool Institute and University College, Liverpool, then graduated with a Ph.D. from Leipzig University and D.Sc. from Oxford. Career Ewart was a demonstrator of botany at Liverpool, and subsequently Science Master at King Edward's School, Birmingham, and lecturer on botany at Birmingham University, where he was for a time deputy professor. In 1905 Ewart was appointed Professor of Botany at the University of Melbourne. He had already completed a laborious and useful piece of work, his translation of Wilhelm Pfeffer's treatise on ''The Physiology of Plants'', the first volume of which was published in 1900, the second in 1903, and the third in 1906. He had also published ''First Stage Botany'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ewartia Meredithiae
''Ewartia meredithiae'', commonly known as the rusty cushion plant, is a Tasmanian endemic cushion plant species. Out of the four species in Australia from this small genus, Tasmania has three, all of which are low growing, alpine species. Description The close branching of shoots, short internodes and tightly packed stems cause the characteristic hemispherical shape of a cushion plant species. It can spread approximately 1 metre in diameter with its adventitious roots forming at various points along the prostrate branches. The leaves are silver grey in colour with rust-coloured hairs. In shape, the leaves are broadly oval and approximately 10mm long. At the ends of the branches, small, white, papery flower heads occur in summer. This morphology allows this species to be very frost tolerant. Distribution and habitat This species is endemic to Tasmania, meaning it is not found anywhere else. It exists in montane vegetation and bolster heath communities throughout the alpin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
