Rhizanthella omissa is a species of flowering plant in the orchid family and is found in the Lamington National Park in Queensland. It is a subterranean herb that grows in casuarina forest and flowers underground. [2] It was first formally described in 2006 by David Jones and Mark Clements in the journal The Orchadian. [3] The species is listed as "endangered" under the Queensland Government Nature Conservation Act 1992 . [4]
The Orchidaceae are a diverse and widespread family of flowering plants, with blooms that are often colourful and fragrant, commonly known as the orchid family.
The Lamington National Park is a national park, lying on the Lamington Plateau of the McPherson Range on the Queensland/New South Wales border in Australia. From Southport on the Gold Coast the park is 85 kilometres (53 mi) to the southwest and Brisbane is 110 kilometres (68 mi) north. The 20,600 hectares Lamington National Park is known for its natural environment, rainforests, birdlife, ancient trees, waterfalls, walking tracks and mountain views.
Dendrobium is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is a very large genus, containing more than 1,800 species that are found in diverse habitats throughout much of south, east and southeast Asia, including China, Japan, India, the Philippines, Indonesia, Australia, New Guinea, Vietnam and many of the islands of the Pacific. Orchids in this genus have roots that creep over the surface of trees or rocks, rarely having their roots in soil. Up to six leaves develop in a tuft at the tip of a shoot and from one to a large number of flowers are arranged along an unbranched flowering stem. Several attempts have been made to separate Dendrobium into smaller genera, but most have not been accepted by the World Checklist of Selected Plant Families.
PhalaenopsisBlume (1825), commonly known as moth orchids, is a genus of about seventy species of plants in the family Orchidaceae. Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end. Orchids in this genus are native to India, Taiwan, China, Southeast Asia, New Guinea and Australia with the majority in Indonesia and the Philippines.
Rhizanthella slateri, commonly known as the eastern underground orchid, is a species of flowering plant in the orchid family and is endemic to New South Wales. It is a mycoheterotrophic herb that spends most of its life under the soil surface, its flowers only sometimes appearing a few millimetres about ground level.
Acianthus, commonly known as mosquito orchids, is a genus of about 25 species of plants in the orchid family, Orchidaceae. Mosquito orchids are terrestrial herbs with a single, heart-shaped, usually ground-hugging leaf and one to many small, green, pinkish or purplish flowers on a fleshy stalk. They are found in New Caledonia, Australia and New Zealand.
Babakin is a small town located in the Wheatbelt region of Western Australia between the towns of Bruce Rock and Corrigin. At the 2016 census the population of Babakin was approximately 54. Facilities in the town include a school, shop, hall and sporting facilities.
Apostasia, commonly known as grass orchids, is a genus of eight species of primitive orchids in the family Orchidaceae. They are terrestrial, evergreen, grass-like plants, barely recognisable as orchids and are distributed in humid areas of the Himalayan region, China, India, Sri Lanka, Southeast Asia, New Guinea, and Queensland. They have many narrow leaves and small yellow or white, non-resupinate, star-like flowers usually arranged on a branched flowering stem.
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.
Dipodium, commonly known as hyacinth orchids, is a genus of about forty species of orchids native to tropical, subtropical and temperate regions of south-east Asia, New Guinea, the Pacific Islands and Australia. It includes both terrestrial and climbing species, some with leaves and some leafless, but all with large, often colourful flowers on tall flowering stems. It is the only genus of its alliance, Dipodium.
Dendrobium bigibbum, commonly known as the Cooktown orchid or mauve butterfly orchid, is an epiphytic or lithophytic orchid in the family Orchidaceae. It has cylindrical pseudobulbs, each with between three and five green or purplish leaves and arching flowering stems with up to twenty, usually lilac-purple flowers. It occurs in tropical North Queensland, Australia and New Guinea.
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.
Peristeranthus hillii, commonly known as the beetle orchid or brown fairy-chain orchid is the only species in the genus Peristeranthus from the orchid family, Orchidaceae. It is an epiphytic or lithophytic orchid with more or less pendulous stems, between three and ten widely spaced, leathery leaves and a large number of pale green, often spotted flowers. It mainly grows on tree trunks and thick vines in rainforest and is found between the Bloomfield River in Queensland and Port Macquarie in New South Wales.
Phaius tankervilleae, commonly known as the greater swamp-orchid, swamp lily, swamp orchid, nun's-hood orchid, nun's orchid, veiled orchid, Lady Tankerville's swamp orchid or 鹤顶兰 , is a species of orchid native to areas from Asia to islands in the Pacific Ocean. It has large, pleated leaves and tall flowering stems bearing up to twenty five white, brown, mauve and yellow flowers. It was named for Lady Tankerville who owned the greenhouse where the first orchid flowered. It was the first tropical orchid to flower in England.
Rhomboda polygonoides , commonly known as the velvet jewel orchid, is a species of terrestrial orchid that is native to New Guinea, New Caledonia, the Solomon Islands and north-eastern Queensland. It has between five and nine narrow egg-shaped, purplish green leaves with a central white stripe and up to fourteen green and white resupinate flowers with the lateral sepals held nearly horizontally.
Melaleuca uncinata, commonly known as broombush, broom honeymyrtle or brushwood, is a plant in the paperbark family native to southern Australia. It is harvested from the wild, and grown in plantations, for broombush fencing. The Noongar names for the plant are kwytyat and yilbarra.

Diurideae is a tribe of orchid in the subfamily Orchidoideae. It contains about 40 accepted genera. As of April 2018, its division into subtribes remained unclear.
Rhizanthella speciosa is a species of flowering plant in the orchid family and is endemic to Barrington Tops in New South Wales. It is a mycoheterotrophic herb that spends its entire life cycle, including flowering, at or below the soil surface. As at September 2020, R. speciosa has not yet been accepted as a valid name by the World Checklist of Selected Plant Families or the Australian Plant Census.
Rhizanthella johnstonii, commonly known as south coast underground orchid, is a species of flowering plant in the orchid family and is endemic to the southwest of Western Australia. It is a subterranean herb that has a horizontal rhizome and a head of up to sixty small white flowers with a pink tinge, surrounded by relatively large, cream-coloured to pale pinkish cream bracts.
