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. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is found in the tropics.
The pseudobulb is a storage organ found in many epiphytic and terrestrial sympodial orchids. It is derived from a thickening of the part of a stem between leaf nodes and may be composed of just one internode or several, termed heteroblastic and homoblastic respectively. All leaves and inflorescences usually arise from this structure. Pseudobulbs formed from a single internode produce the leaves and inflorescence from the top, while those that are formed from several internodes can possess leaves along its length. The modified sheath leaves that appear at the base of a pseudobulb and often enfold all or part of it are usually dry and papery, though in some orchids the sheaths bear leaf blades and the leaves at the pseudobulb's apex are reduced to scales.
Corm, bulbo-tuber, or bulbotuber is a short, vertical, swollen underground plant stem that serves as a storage organ that some plants use to survive winter or other adverse conditions such as summer drought and heat (perennation).
Cymbidium, commonly known as boat orchids, is a genus of evergreen flowering plants in the orchid family Orchidaceae. Orchids in this genus are epiphytic, lithophytic, terrestrial or rarely leafless saprophytic herbs usually with pseudobulbs. There are usually between three and twelve leaves arranged in two ranks on each pseudobulb or shoot and lasting for several years. From one to a large number of flowers are arranged on an unbranched flowering stem arising from the base of the pseudobulb. The sepals and petals are all free from and similar to each other. The labellum is significantly different from the other petals and the sepals and has three lobes. There are about fifty-five species and sixteen further natural hybrids occurring in the wild from tropical and subtropical Asia to Australia. Cymbidiums are well known in horticulture and many cultivars have been developed. The genome of Cymbidium mannii has been sequenced to study epiphytism and crassulacean acid metabolism.
Tipularia discolor, the crippled cranefly or crane-fly orchid, is a perennial terrestrial woodland orchid, a member of the family Orchidaceae. It is the only species of the genus Tipularia found in North America. It occurs in the southeastern United States from Texas to Florida, the range extending north into the Ohio Valley and along the Appalachians as far north as the Catskills. There are also isolated populations in Massachusetts and in the Great Lakes region. Tipularia discolor is a common early pioneer during secondary succession, readily colonizing woodland habitats during early developmental or regrowth stages.
Gastrodia, commonly known as potato orchids, is a genus of terrestrial leafless orchids in the family Orchidaceae, about ninety of which have been described. Orchids in this genus have fleshy, upright stems and small to medium-sized resupinate flowers with narrow sepals and petals. They are native to Asia, Australia, New Zealand, central Africa, and various islands of the Indian and Pacific Oceans.
Gastrodia elata is a saprophytic perennial herb in the family Orchidaceae. It is found in Nepal, Bhutan, India, Japan, Korea, Siberia, Taiwan, and China.
Didymoplexis, commonly known as crystal orchids or as 双唇兰属 , is a genus of terrestrial leafless orchids in the family Orchidaceae, about twenty species of which have been described. Orchids in this genus have swollen, fleshy rhizomes and thin, pale, upright fleshy flowering stems with resupinate, bell-shaped white or pale yellowish brown flowers. They are native to Africa, Madagascar, Southeast Asia, Australia and various islands of the Pacific.
Aphyllorchis, commonly known as pauper orchids or as 無葉蘭屬/无叶兰属 , is a genus of about twenty species of terrestrial leafless orchids in the family Orchidaceae. Orchids in this genus have fleshy, upright stems and small to medium-sized resupinate flowers with narrow sepals and petals. They are native to a region extending from India east to China and Japan, south to Indonesia, New Guinea and Queensland.
Peristeria elata is a species of orchid occurring from Central America to Panama, Venezuela, and Ecuador. It is the type species of its genus. It is commonly referred to as the Holy Ghost orchid, dove orchid, or flower of the Holy Spirit in English, and, as the flor del Espiritu Santo in Spanish.
4‑Hydroxybenzaldehyde (para‑hydroxybenzaldehyde) is an organic compound with the formula C6H4OH(CHO). Along with 2-hydroxybenzaldehyde and 3-hydroxybenzaldehyde, it is one of the three isomers of hydroxybenzaldehyde.
Gastrodin is a chemical compound which is the glucoside of gastrodigenin. It has been isolated from the orchid Gastrodia elata and from the rhizome of Galeola faberi. It can also be produced by biotransformation of 4-hydroxybenzaldehyde by Datura tatula cell cultures.
Gastrodia sesamoides, commonly known as cinnamon bells or common potato orchid in Australia and as the pot-bellied orchid or cinnamon sticks in New Zealand, is a leafless, terrestrial saprophytic orchid in the family Orchidaceae. It has a thin, fleshy brown flowering stem and up to twenty five drooping, brownish, self-pollinating flowers that are white inside. Growing in a wide range of habitats, it is native to Australia and New Zealand.
2,4-Bis(4-hydroxybenzyl)phenol is a phenolic compound produced by the saprophytic orchid Gastrodia elata and by the myco-heterotroph orchid Galeola faberi.
Gastrol is a phenolic compound produced by the saprophytic orchid Gastrodia elata.
Gastrodigenin is a phenolic compound found in the rhizome of Gastrodia elata.
Gastrodia queenslandica, commonly known as rainforest bells, is a leafless terrestrial mycotrophic orchid in the family Orchidaceae. It has one or two small, yellowish brown, tube-shaped flowers on a thin, brittle flowering stem and grows in rainforest in tropical north Queensland, Australia.
Gastrodia urceolata, commonly known as white potato orchid, is a leafless terrestrial mycotrophic orchid in the family Orchidaceae. It has a pale brown, fleshy flowering stem and up to fifty five upright, white to pale brown flowers. It is only known from a single population near Atherton in Queensland.
Gastrodia spatulata is a species of Gastrodia native to Indonesia and Malaysia. It is known from Borneo and Java.
Gastrodia agnicellus is a species of orchid in the genus Gastrodia, found in Madagascar and described in Curtis's Botanical Magazine by Johan Hermans in 2020. It has been said to be "the ugliest orchid in the world", with "brown, fleshy and grotesque" flowers. Like all species in its genus, it is leafless and mycotrophic.
