Elythranthera
''Elythranthera'', commonly known as enamel orchids, was a previously accepted genus of flowering plants in the orchid family, Orchidaceae. It contained two species and a named hybrid, all endemic to the south-west of Western Australia. The genus was first formally described in 1963 by the Australian botanist Alex George who published his description in ''Western Australian Naturalist''. Orchids in the genus ''Elythranthera'' had previously been included in ''Glossodia'' section ''Elythranthera''. Two species were recognised: *''Elythranthera brunonis'' (Endl.) A.S.George now known as '' Caladenia brunonis'' (Endl.) Rchb.f. - purple enamel orchid; *''Elythranthera emarginata'' (Lindl.) A.S.George now known as '' Caladenia emarginata'' (Lindl.) Rchb.f. - pink enamel orchid. A hybrid between the two species was known as ''Elythranthera x intermedia''. ( Fitzg.) M.A.Clem In 2015, as a result of studies of molecular phylogenetics, Mark Clements transferred the two ''Elythrant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caladenia Brunonis
''Caladenia brunonis'', commonly known as the purple enamel orchid, is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It is a ground orchid with a single flattened, hairy leaf and up to three glossy purple flowers. It has recently been known as ''Elythranthera brunonis'' since 1963 but recent discoveries suggest its inclusion in the genus ''Caladenia''. Description ''Caladenia brunonis'' is a terrestrial, perennial, deciduous, sympodial herb with a few inconspicuous, fine roots and a tuber partly surrounded by a fibrous, multi-layered protective sheath. It has a single flattened, dark green, hairy leaf, long and about wide with a reddish-purple underside. Up to three glossy purple flowers long and wide are borne on a spike tall. The sepals and petals spread apart from each other, have blackish tips and are blotched with red or purple on their backs. The dorsal sepal is erect, long and wide. The lateral sepals and petals a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caladenia Emarginata
''Caladenia emarginata'', commonly known as the pink enamel orchid, is a plant in the orchid family Orchidaceae and is endemic to the south-west of Western Australia. It is a ground orchid with a single flattened, hairy leaf and up to four glossy pink flowers. It is similar to ''Caladenia brunonis'' but is usually a shorter plant but with larger, pink flowers. It has been known as ''Elythranthera emarginata'' since 1963 but recent discoveries suggest its inclusion in the genus ''Caladenia''. Description ''Caladenia emarginata'' is a terrestrial, perennial, deciduous, sympodial herb with a few inconspicuous, fine roots and a tuber partly surrounded by a fibrous, multi-layered protective sheath and often forms colonies. It has a single flattened, dark green, hairy leaf, long and about wide with a reddish base. Up to four glossy pink flowers long and wide are borne on a spike tall. The sepals and petals spread apart from each other and are blotched with red or purple on their b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Orchids Of Australia
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are '' Bulbophyllum'' (2,000 species), '' Epidendrum'' (1,500 species), '' Dendrobium'' (1,400 species) and '' Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australian Herbarium
The Western Australian Herbarium is the State Herbarium in Perth, Western Australia. It is part of the State government's Department of Parks and Wildlife, and has responsibility for the description and documentation of the flora of Western Australia. It has the Index Herbariorum code of PERTH. The Hebarium forms part of the Australasian Virtual Herbarium.

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

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 ...
