Orchidoideae
The Orchidoideae, or the orchidoid orchids, are a subfamily of the orchid family (Orchidaceae) that contains around 3630 species. Species typically have a single (monandrous), fertile anther which is erect and basitonic. Description The subfamily Orchidoideae and the previously recognized subfamily Spiranthoideae are considered the closest allies in the natural group of the monandrous orchids because of several generally shared characters: * a shared terrestrial habit * sectile (capable of being severed) or granular pollinia *erect anthers. Taxonomy Phylogeny of the Orchidoideae is volatile and still subject to change. Historically, the Orchidoideae have been partitioned into up to 6 tribes, including Orchideae, Diseae, Cranichideae, Chloraeeae, Diurideae, and Codonorchideae. However, the most recent molecular phylogenetics analysis led by Chase et al. in 2015 and subsequently by Chen et al. in 2017 indicates that the Orchidoideae should be split into 4 tribes: the Orchide ...

Cryptostylis
''Cryptostylis'', commonly known as tongue orchids, is a genus of flowering plants from the orchid family. Tongue orchids are terrestrial herbs with one to a few stalked leaves at the base of the flowering stem, or leafless. One to a few dull coloured flowers are borne on an erect flowering stem. The most conspicuous part of the flower is the labellum, compared to the much reduced sepals and petals. At least some species are pollinated by wasps when they attempt to mate with the flower. There are about twenty five species found in South Asia, Southeast Asia and the South Pacific. Description Orchids in the genus ''Cryptostylis'' are terrestrial, perennial herbs with a thick, branching underground rhizome with vertical shoots forming at nodes. The plant has thick, fleshy roots but lacks a tuber. There are one to a few erect leaves, each with a distinct petiole and often purple on the lower surface, although '' C. hunteriana'' is saprophytic and leafless. New leaves are produced ...

Corybas (plant)
''Corybas'', commonly known as helmet orchids, is a genus of about 120 species of plants in the orchid family, Orchidaceae. Helmet orchids are small, perennial, deciduous herbs and are nearly always terrestrial. They have a single leaf at their base and a single flower on a short stalk, the flower dominated by its large dorsal sepal and labellum. Species of ''Corybas'' are found in Australia, New Zealand, New Guinea, Southeast Asia, the Himalayas, southern China, many Pacific islands and a few sub-Antarctic islands. Description Orchids in the genus ''Corybas'' are perennial, deciduous, sympodial, usually terrestrial herbs, lacking roots. (A few sometimes grow as epiphytes on the fibrous bark of tree ferns or on the mossy branches of trees.) They have an underground tuber which is more or less spherical and fleshy. New tubers form at the end of root-like stolons. There is a single, heart-shaped, kidney-shaped or almost round leaf, usually at ground level and a short erect ...

Rhizanthellinae
''Rhizanthella'', commonly known as underground orchids, is a genus of flowering plants in the orchid family, Orchidaceae and is endemic to Australia. All are leafless, living underground in symbiosis with mycorrhizal fungi. The inflorescence is a head of flowers held at, or just above the ground but mostly covered by soil or leaf litter and little is known about the mechanism of pollination. Description Orchids in the genus ''Rhizanthella'' are mostly underground, perennial, sympodial, mycotrophic herbs with fleshy underground stems which produce new shoots at nodes where there are colourless leaf-like cataphylls. There are no roots and new tubers form at the end of short stems. The leaves are reduced to scale-like structures lacking chlorophyll, pressed against and sheathing the stems. The inflorescence is a head containing many flowers and is held at, or just above ground level but the head is usually covered with leaf litter or soil. The head is surrounded by a large n ...

Caleana
''Caleana'', commonly known as duck orchids, is a genus of flowering plants in the orchid family, Orchidaceae that is found in Australia and New Zealand. The Australian species are found in all states but have not been recorded in the Northern Territory. Duck orchids have a single leaf and one or a few, dull-coloured, inconspicuous flowers. Most species are found in Western Australia but one species ('' C. major'') occurs in eastern Australia and one ('' C. minor'') occurs in eastern Australia and New Zealand. Orchids in this genus as well as the hammer orchids (''Drakaea'') are pollinated by male thynnid wasps. Description Orchids in the genus ''Caleana'' are terrestrial, perennial, deciduous, sympodial herbs usually with a few inconspicuous, fine roots and a dark red, oval-shaped, tuber. Replacement tubers called "droppers" form at the end of long root-like stolons. A single linear to egg-shaped leaf long develops near the base of the plant during the growing season and w ...

Adenochilus
''Adenochilus'', commonly known as gnome orchids is a genus of two species of flowering plants in the orchid family Orchidaceae, one endemic to New Zealand and the other to Australia. Both species have a long, horizontal, underground rhizome with a single leaf on the flowering stem and a single resupinate flower with its dorsal sepal forming a hood over the labellum and column. Description Orchids in the genus ''Adenochilus'' are terrestrial, perennial, deciduous, sympodial herbs with a long, thin, horizontal underground rhizome and a single leaf either on a long stalk or attached to the flowering stem. When present, there is a single resupinate flower on the end of the flowering stem. The dorsal sepal is free and forms a hood over the labellum and column. The lateral sepals and petals are free from each other, longer and narrower than the dorsal sepal, and spread widely apart. The labellum is also free, attached at the base of the column by a short stalk or "claw". The labell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiloglottis
''Chiloglottis'', commonly known as wasp orchids, ant orchids or bird orchids, is a genus of about 25 species of flowering plants in the orchid family, Orchidaceae and is found in eastern Australia and New Zealand. Wasp orchids are terrestrial herbs which grow in colonies of genetically identical plants. They usually have two leaves at the base of the plant and a single resupinate ("upside-down") flower. The labellum is more or less diamond-shaped and has calli resembling the body of a wingless female wasp. Taxonomy and naming The genus ''Chiloglottis'' was first formally described in 1810 by Robert Brown. Brown described '' Chiloglottis diphylla'' at the same time, making it the type species. David Jones has transferred some species, especially those commonly known as "bird orchids" (''Simpliglottis'') and "ant orchids" (''Myrmechila'') to other genera, but the change has not been widely accepted.

Calochilus
''Calochilus'', commonly known as beard orchids, is a genus of about 30 species of plants in the orchid family, Orchidaceae. Beard orchids are terrestrial herbs with a single leaf at the base of the plant, or no leaves. Their most striking feature is a densely hairy labellum, giving rise to their common name. Beard orchids, unlike some other Australian orchids, do not reproduce using daughter tubers, but self-pollinate when cross-pollination has not occurred. Most species occur in Australia but some are found in New Zealand, New Guinea and New Caledonia. Description Orchids in the genus ''Calochilus'' are terrestrial, perennial, deciduous, sympodial herbs with a few inconspicuous, fine roots and a pair of egg-shaped tubers lacking a protective fibrous sheath. The tubers produce replacement tubers on the end of a short, root-like stolons. There is either a single, linear, fleshy, convolute leaf, usually channelled, sometimes triangular in cross section, or there is no leaf. ...

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] |
