Richard Sanders Rogers
Richard Sanders Rogers (2 December 1861 – 28 March 1942) was a distinguished Australian medical doctor, and world authority on Australasian orchids. He described over 80 Australian orchid species, three from New Zealand and 30 from New Guinea as well as three new genera including one from New Zealand. He was a consulting physician at the Adelaide Hospital and a member of its board. He may have been the first to practise hypnotism during surgery, allowing him to remove a cyst from a woman's breast without anaesthetics "''while she was still awake and talking to assistants and witnesses standing nearby''." Biography Rogers was the son of Joseph Rogers and his wife Ann Childers Rogers (née Williams) and was one of their nine children. He was educated at Pulteney Street School, now Pulteney Grammar School and the University of Adelaide, graduating B.A. with first class honours in 1881. He taught at Prince Alfred College, Adelaide before earning a scholarship to study medicine at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Orchids Of Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orchids Of Western Australia
Among the many wildflowers in Western Australia, there are around four hundred species of orchids. Early identifications One of the first botanists to study Western Australia was Archibald Menzies, aboard HMS ''Discovery'', who explored King George Sound in 1791. Many of the samples (including orchids) were lost in the return to England, but those that did survive were documented in ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', published by Robert Brown in 1810. The first three orchids from Western Australia to be named were ''Caladenia menziesii'' (now '' Leptoceras menziesii''), '' Caladenia flava'', and ''Diuris longifolia''. In 1802 Robert Brown himself collected 500 specimens of flora from Western Australia, including: * ''Diuris emarginata'' var. ''emarginata'' * ''Diuris emarginata'' var. ''pauciflora'' *'' Diuris setacea'' *'' Epiblema grandiflorum'' *''Microtis alba'' *'' Microtis media'' *'' Microtis pulchella'' *'' Prasophyllum gibbosum'' *''Prasoph ...

Caladenia
''Caladenia'', commonly known as spider orchids, is a genus of 350 species of plants in the orchid family, Orchidaceae. Spider orchids are terrestrial herbs with a single hairy leaf and a hairy stem. The labellum is fringed or toothed in most species and there are small projections called calli on the labellum. The flowers have adaptations to attract particular species of insects for pollination. The genus is divided into three groups on the basis of flower shape, broadly, spider orchids, zebra orchids and cowslip orchids, although other common names are often used. Although they occur in other countries, most are Australian and 136 species occur in Western Australia, making it the most species-rich orchid genus in that state. Description Orchids in the genus ''Caladenia'' are terrestrial, perennial, deciduous, sympodial herbs with a few inconspicuous, fine roots and a tuber partly surrounded by a fibrous sheath. The tuber produces two "droppers" which become daughter tubers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IBRA
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature. Based on this system, the world is also split into 14 terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89 bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape. IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mallee (biogeographic Region)
Mallee, also known as Roe Botanical District, is a biogeographic region in southern Western Australia.
