Flora Of Tasmania
The biodiversity of Tasmania is of Biology, biological and Paleoecology, paleoecological interest. A state of Australia, it is a large Australasia, South Pacific archipelago of one large main island and a range of smaller islands. The terrain includes a variety of reefs, atolls, small islands, and a variety of Topography, topographical and Edaphology, edaphic regions on the largest island, all of which promote the development of concentrated biodiversity. During long periods geographically and genetically isolated, it is known for its unique flora and fauna. The region's Oceanic climate, climate is oceanic. Evolution The marine fauna of the period, separate from that of the southwest Pacific, was distinguished as the "Maori province". Gondwana began its fragmentation in the middle and upper Jurassic, and the arrival of benthic invertebrate fauna is visible in fossil deposits.

William Archer (architect)
William Archer (1820–1874) was an Australian architect, naturalist, grazier, politician and member of the prominent Archer family. He was the second son of Thomas Archer, a prominent pastoralist and politician himself. A keen interest in architecture led to him going to London to study architecture when he finished school, where he studied under William Rogers and Robert Stephenson. During his life he built many colonial buildings across Tasmania, served as a member of both the Tasmanian House of Assembly and Tasmanian Legislative Council and made significant contributions to botany, with several native Tasmanian plants named after him. Despite this he died penniless at his brothers house Fairfield on 15 October 1874. Life Archer was born in Launceston, Van Diemen's Land (now Tasmania) into the influential local Archer family, owners of the Brickendon Estate and Woolmers Estate, a closely knit and pious Anglican family to Thomas (1780–1850), a banker and landholder, an ...

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 cultivar group, 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, Fungus, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), Chytridiomycota, chytrids, oomycetes, slime moulds and Photosynthesis, 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 variou ...

Eaglehawk Neck
Eaglehawk Neck, officially Teralina / Eaglehawk Neck, is a narrow isthmus that connects the Tasman Peninsula with the Forestier Peninsula and hence to the rest of Tasmania, Australia. It is about north-east of the town of Nubeena in the local government area of Tasman in the South-east region of Tasmania. At the , the locality had a population of 385. Location and features The isthmus is around long and less than wide at its narrowest point. The location features rugged terrain and several unusual geological formations including the Tessellated Pavement. Clyde Island, at the northern entry to Pirates Bay, is accessible for crossings at low tide and is the site of two graves, and a rumbling blow hole that cleaves the island. Eaglehawk Neck is a holiday destination. On the eastern side, a beach that stretches around Pirates' Bay is a popular surfing area. In summer the population rises as people return to their holiday homes. European history Eaglehawk Neck was gazet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muelleria (journal)
''Muelleria'' is a peer-reviewed scientific journal on botany published by the Royal Botanic Gardens Melbourne. It focuses on topics relating to plants, algae, and fungi in the southern hemisphere and Australia in particular. The journal was named in honour of Victorian Government botanist Ferdinand von Mueller. ''Muelleria'' commenced publication in 1955 with funding from the Maud Gibson Trust. The trust was initiated in 1945 following the donation of £20,000 by Maud Gibson, a daughter of William Gibson, founder of the Foy & Gibson department store chain. ''Muelleria'' was one of a number of botanical journals initiated by Australian herbaria after World War II, reflecting the increased level of botanical research undertaken at this time. James Hamlyn Willis was the editor of the three initial issues. ''Muelleria'' is available via the Biodiversity Heritage Library.

Pappus (botany)
In Asteraceae, the pappus is the modified calyx_(botany), calyx, the part of an individual floret, that surrounds the base of the petal, corolla tube in flower. It functions as a dispersal mechanism for the achenes that contain the seeds. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. In genera such as ''Bidens'' the pappus has hooks that function in mechanical dispersal. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the Taraxacum, dandelion plays a vital role in the wind-aided dispersal of its seeds. By cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple fruit, simple dry fruits, dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and Dehiscence (botany), indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encom ...

Pseudanthium
A pseudanthium (; : pseudanthia) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (biology), family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla (flower), corolla is fused into a tube. Flowers on th ...
