It is famous for its unpredictable appearance; in many localities it has been seen just once. It is found in beech, oak, pine and spruce forests on base-rich soils. It is a rare and critically endangered plant in habitat, and is believed to be extinct throughout much of its former range, although it has been recently confirmed in the United Kingdom (2009), an area where the plants were believed to have gone extinct.
The plants are protected in many locales, and removing the plants from habitat or disturbing the plants, even for scientific study, can be a very serious matter in many jurisdictions. These plants are exceptionally rare and should never be removed from habitat or disturbed.
In 1926 the Welsh botanist Eleanor Vachell was asked by the British Museum to investigate a report of the Ghost Orchid in England. For many years the Welsh National Herbarium at Amgueddfa Cymru (National Museum of Wales) had only a small rhizome that had been gathered by Vachell on 29 May 1926.

Satyrium epipogium L.
Once thought to be saprophytic, these hardy plants are actually obligate mycoheterotrophs (or epiparasites) that obtain nutrients from mycorrhizal networks involving basidomycete fungi that are in turn associated with the roots of various species of coniferous trees. They grow from an underground, burrowing stem which lacks chlorophyll and possesses ephemeral leaves that are small scales. The plants only emerge above ground to flower, especially during very wet summers in Western Europe.
The plants have an extremely wide range of distribution. The species is widespread across much of Europe and northern Asia from Spain to Kamchatka and south the Himalayas. It is, however, exceptionally rare in habitat. The plants are all found in areas which typically experience cold winters. The plant's rhizomes are densely colonized by fungi bearing clamp-connections and dolipores, all basidiomycetes, gill or pore-forming mushroom species that are normally found growing in mycorrhizal association with the roots of coniferous trees.
These plants harness an array of fungal symbionts across several families, often simultaneously. Analysis of these plants have identified Inocybe species as exclusive symbionts for 75% of the plants in habitat, as well as others (Hebeloma, Xerocomus, Lactarius and Thelephora). The plants also host ascomycete endophytes, which appear to assist the plant in parasitizing some of the plant's basidiomycete symbionts.
The plants defy cultivation outside of laboratory conditions, as they require not only specific fungal symbionts, but also specific host trees with which these mushroom species form mycorrhizal relationships. Large plants of this species can produce a rather stunning woodland display with up to a dozen flower stalks at once bearing 3–4 flowers each growing out of coniferous leaf litter.
Dendrophylax lindenii, the ghost orchid (a common name also used for Epipogium aphyllum) is a perennial epiphyte from the orchid family (Orchidaceae). It is native to Florida and Cuba. Other common names include palm polly and white frog orchid.Eleanor Vachell
Eleanor Vachell (1879–1948) was a Welsh botanist who is remembered especially for her work identifying and studying the flora of Glamorgan and her connection with the National Museum of Wales where she was the first woman to be a member of its Council and Court of Governors. The museum now holds her botanical diary, notes, books, records and specimens.Epipogium
Epipogium, commonly known as ghost orchids or as 虎舌兰属 (hu she lan shu), is a genus of four species of terrestrial leafless orchids in the family Orchidaceae. Orchids in this genus have a fleshy, underground rhizome and a fleshy, hollow flowering stem with small, pale coloured, drooping, short-lived flowers with narrow sepals and petals. They are native to a region extending from tropical Africa to Europe, temperate and tropical Asia, Australia and some Pacific Islands.Fiddler's Elbow National Nature Reserve
Fiddler’s Elbow National Nature Reserve is a steep sided, woodland national nature reserve of 45 hectares in the Upper Wye Valley to the north of Monmouth in Wales, close to the Wales–England border. It is designated as a Site of Special Scientific Interest (SSSI) for its biological characteristics, containing a wide variety of flora.Ghost orchid
Ghost orchid, is a common name for several orchids, and may refer to:
Dendrophylax lindenii, the American ghost orchid
Epipogium aphyllum, the Eurasian ghost orchidLeningrad Oblast
Leningrad Oblast (Russian: Ленингра́дская о́бласть, tr. Leningradskaya oblast’, IPA: [lʲɪnʲɪnˈgratskəjə ˈobləsʲtʲ]) is a federal subject of Russia (an oblast). It was established on August 1, 1927, although it was not until 1946 that the oblast's borders had been mostly settled in their present position. The oblast was named after the city of Leningrad (now Saint Petersburg). Unlike the city, the oblast retains the name of Leningrad.
The oblast overlaps the historic region of Ingria and is bordered by Finland (Kymenlaakso and South Karelia) in the northwest and Estonia (Ida-Viru County) in the west, as well as five federal subjects of Russia: the Republic of Karelia in the northeast, Vologda Oblast in the east, Novgorod Oblast in the south, Pskov Oblast in the southwest, and the federal city of Saint Petersburg in the west.
The first governor of Leningrad Oblast was Vadim Gustov (in 1996–1998). The current governor, since 2012, is Aleksandr Drozdenko.
The oblast has an area of 84,500 square kilometers (32,600 sq mi) and a population of 1,716,868 (2010 Census); up from 1,669,205 recorded in the 2002 Census. The most populous town of the oblast is Gatchina, with 88,659 inhabitants (as of the 2002 Census). Leningrad Oblast is highly industrialized.List of extinct and endangered species of Lithuania

The flowering plant families appearing most frequently in the list are the Asteraceae and the Orchidaceae. Commonly cited reasons for plant extinctions in the UK include habitat loss, drainage, changes to farming systems and overgrazing. The most threatened habitats in the UK include meadows, peat bogs and marshes. The United Kingdom and Ireland both have a relatively small proportion of forest cover compared to other countries. In 2017 the UK was 13% forested In 2019 Ireland was just 11% forested. Charities involved in plant conservation in the UK include The Wildlife Trusts, Plantlife, The Botanical Society of Britain and Ireland, Back From The Brink and Chester Zoo. Sightings of any of these species should be reported to the Botanical Society of Britain and Ireland, or the British Bryological Society in the case of mosses.List of sequenced plastomes
A plastome is the genome of a plastid, a type of organelle found in plants and in a variety of protoctists. The number of known plastid genome sequences grew rapidly in the first decade of the twenty-first century. For example, 25 chloroplast genomes were sequenced for one molecular phylogenetic study.The flowering plants are especially well represented in complete chloroplast genomes. As of January, 2017, all of their orders are represented except Commelinales, Picramniales, Huerteales, Escalloniales, Bruniales, and Paracryphiales.
A compilation of all available complete plastid genomes is maintained by the NCBI in a public repository.List of the vascular plants in the Red Data Book of Russia

This is a comprehensive list of the vascular plants of the Karelian Isthmus, a land mass in Russia connected to Finland on one side and otherwise surrounded by three bodies of water: the Gulf of Finland, the Neva River, and Lake Ladoga.Orchid of the Year
The Orchid of the Year is a yearly honor given since 1989 to an orchid species native to Germany by the Arbeitskreis Heimische Orchideen (Native Orchid Research Group, AHO), a German orchid conservation federation. The choice of orchids follows the endangerment of the species or its habitat due to human pressure.
