Epacris Curtisiae
''Epacris curtisiae'' is a species of flowering plant in the heath family Ericaceae and is endemic to north-western Tasmania. It is a shrub with egg-shaped to almost circular leaves and tube-shaped white flowers crowded in upper leaf axils. Description ''Epacris curtisiae'' is a shrub that typically grows to a height of and has several erect, slender stems. Its leaves are more or less flat, egg-shaped with the narrower end towards the base, to more or less circular, long and wide on a petiole long. The flowers are arranged singly in leaf axils forming clusters long at the ends of branches, each flower on a peduncle long. The five sepals are egg-shaped to elliptic, long and tinged with pink and the petals are white, joined at the base to form a white tube long. The five stamens and the style are enclosed within the petal tube. Taxonomy and naming ''Epacris curtisiae'' was first formally described in 1988 by S. Jean Jarman in the '' Papers and Proceedings of the Royal So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Tasmanian Botanical Gardens
The Royal Tasmanian Botanical Gardens (''RTBG''), which cover an area of approximately 14 hectares (34.6 acres), in Hobart located within the Queens Domain. History The gardens were established in 1818 and is the second oldest Botanical Gardens in Australia – the Sydney Botanic gardens were founded two years earlier. The land was originally occupied by the Muwinina people. Archaeological excavations have uncovered extensive shell middens and stone artifacts dating back more than 5000 years. Gardens The Gardens hold historic plant collections and a large number of significant trees, many dating back to the nineteenth century. It also has an increasing number of important conservation collections of Tasmanian plants, of which the King's Lomatia is one of the most unusual, and the world's only Subantarctic Plant House. Here, plants from subantarctic islands in high southern latitudes are displayed in a climatically-controlled environment, where chilly fogs and mists mirror the ...

Its original aim was to ‘develop the physical character of the Island and illustrate its natural history and productio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Tasmania
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] |
Ericales Of Australia
The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, and azalea. The order includes trees, bushes, lianas, and herbaceous plants. Together with ordinary autophytic plants, the Ericales include chlorophyll-deficient mycoheterotrophic plants (e.g., '' Sarcodes sanguinea'') and carnivorous plants (e.g., genus ''Sarracenia''). Many species have five petals, often grown together. Fusion of the petals as a trait was traditionally used to place the order in the subclass Sympetalae. Mycorrhizal associations are quite common among the order representatives, and three kinds of mycorrhiza are found exclusively among Ericales (namely, ericoid, arbutoid and monotropoid mycorrhiza). In addition, some families among the order are notable for their exceptional ability to accumulate aluminum. Ericales are a cosmopolitan order. Areas of distribution of fa ...

Epacris
''Epacris'' is a genus of about forty species of flowering plants in the family Ericaceae. It was formerly treated in a closely related but separate family Epacridaceae, but the various genera within Epacridaceae including ''Epacris'' have been revised in their relationships to each other and brought under the common umbrella of the Ericaceae. The genus ''Epacris'' is native to eastern and southeastern Australia (southeast Queensland south to Tasmania and west to southeast South Australia), New Caledonia and New Zealand. The species are known as heaths or Australian heaths. Description Plants in the genus ''Epacris'' are shrubs with simple leaves that are a similar colour on both surfaces and with flowers arranged singly in leaf axils near the ends of the branches, sometimes extending along the branches. Each flower is surrounded by many bracts and five, usually glabrous sepals. The petals are joined to produce a cylindrical or bell-like tube with five lobes on the end. The ...

Winifred Curtis
Winifred Mary Curtis (15 June 1905 – 14 October 2005) was a United Kingdom, British-born Australian botanist, author and a pioneer researcher in plant embryology and cell (biology), cytology who played a prominent role in the department of botany at the University of Tasmania (UTAS), where the main plant science laboratory is named in her honour. Biography Curtis was born on 15 June 1905 in London, the only child of Herbert John Curtis and Elizabeth Winifred Curtis (née Baker). Curtis lived in India for several years as a child after her father was posted there. She was a gifted student, and studied science at University College, London from 1924, winning various awards and scholarships. She graduated in 1927 and completed an honours degree in Botany the following year for research on ''Spartinia townsendii'', and ''Taraxacum'' (dandelions). This was followed by several years of travel through Europe and teaching in Manchester and Hampstead. In 1939 she emigrated to Australi ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Style (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and slen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...
