Platanthera bifolia, commonly known as the lesser butterfly-orchid, [1] is a species of orchid in the genus Platanthera , having certain relations with the genus Orchis , where it was previously included and also with the genus Habenaria . It is a Palaearctic species occurring from Ireland in the west, across Europe and Asia to Korea and Japan. It is also found in North Africa. [2] [3] The name Platanthera is derived from Greek, meaning 'broad anthers', while the species name, bifolia, means 'two leaves'.
Lesser butterfly-orchids are not to be confused with the greater butterfly-orchid, which are about the same size. Lesser butterfly-orchids are distinguished by their two shining green basal leaves, especially of the hill form, which are shorter and broader and by the angle of the pollinia. The upper sepal and petals form a loose triangular hood above the pollinia, which lie parallel and close together, obscuring the opening into the spur, which is long and almost straight. There are usually around 25 white flowers tinged with yellow-green in a slim flower spike. The flowers are night-scented, but the chemical components of the scent are different from those of greater butterfly-orchid and attract different pollinators.
Hybrids of the two butterfly-orchids are rare, as are those between lesser butterfly-orchid and other species. However, hybrids have been recorded with frog orchid in South Uist (1949) and with the common spotted-orchid and the heath spotted-orchid.
The lesser butterfly-orchid occupies a wide range of habitats, being far more tolerant of acid conditions than the greater butterfly-orchid. They are found in grasslands, woodlands (especially beech woods in southern England), in hill pastures up to 400m, on heaths and moorland, and in tussocky marshy ground.
Sphingid moths are attracted by the scent of this orchid, and tend to hover in front of the flowers, resting their forelegs on the lip. As the proboscis enters the spur it pushes between the pollinia, dislodging the sticky discs which adhere to it. Pollinators include pine, small elephant and, to a lesser extent, elephant hawk-moths.
This species has suffered a serious decline, especially in central and southern England, as a result of woodland clearance. Upland populations in the north and west have suffered from overgrazing.
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.
Anacamptis pyramidalis, the pyramidal orchid, is a perennial herbaceous plant belonging to the genus Anacamptis of the family Orchidaceae. The scientific name Anacamptis derives from Greek ανακάμτειν 'anakamptein' meaning 'bend forward', while the Latin name pyramidalis refers to the pyramidal form of the inflorescence.
Dactylorhiza maculata subsp. fuchsii, the common spotted orchid, is a subspecies of flowering plant in the orchid family Orchidaceae.
Bulbophyllum is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is the largest genus in the orchid family and one of the largest genera of flowering plants with more than 2,000 species, exceeded in number only by Astragalus. These orchids are found in diverse habitats throughout most of the warmer parts of the world including Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans. Orchids in this genus have thread-like or fibrous roots that creep over the surface of trees or rocks or hang from branches. The stem is divided into a rhizome and a pseudobulb, a feature that distinguished this genus from Dendrobium. There is usually only a single leaf at the top of the pseudobulb and from one to many flowers are arranged along an unbranched flowering stem that arises from the base of the pseudobulb. Several attempts have been made to separate Bulbophyllum into smaller genera, but most have not been accepted by the World Checklist of Selected Plant Families.
Brassavola is a genus of 21 orchids. They were named in 1813 by the Scottish botanist Robert Brown. The name comes from the Italian nobleman and physician Antonio Musa Brassavola. This genus is abbreviated B. in trade journals.
Phalaenopsis, also 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.
Zoophily, or zoogamy, is a form of pollination whereby pollen is transferred by animals, usually by invertebrates but in some cases vertebrates, particularly birds and bats, but also by other animals. Zoophilous species frequently have evolved mechanisms to make themselves more appealing to the particular type of pollinator, e.g. brightly colored or scented flowers, nectar, and appealing shapes and patterns. These plant-animal relationships are often mutually beneficial because of the food source provided in exchange for pollination.
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.
Drakaea is a genus of 10 species in the plant family Orchidaceae commonly known as hammer orchids. All ten species occur only in the south-west of Western Australia. Hammer orchids are characterised by an insectoid labellum that is attached to a narrow, hinged stem, which holds it aloft. The stem can hinge only backwards, where the broadly winged column carries the pollen and stigma. Each species of hammer orchid is pollinated by a specific species of thynnid wasp. Thynnid wasps are unusual in that the female is flightless and mating occurs when the male carries a female away to a source of food. The labellum of the orchid resembles a female thynnid wasp in shape, colour and scent. Insect pollination involving sexual attraction is common in orchids but the interaction between the male thynnid wasp and the hammer orchid is unique in that it involves the insect trying to fly away with a part of the flower.
Lambert's Castle is an Iron Age hillfort in the county of Dorset in southwest England. Since 1981 it has been designated as a Site of Special Scientific Interest (SSSI) on account of its geology, archaeology and ecology. The hillfort is designated a scheduled monument together with a bowl barrow, the sites of a post-medieval fair and a telegraph station. The site was on the Heritage at Risk Register but was removed in 2022 as a result of the Hillforts and Habitats Project.
The genus Platanthera belongs to the subfamily Orchidoideae of the family Orchidaceae, and comprises about 150 species of orchids. The members of this genus, known as the butterfly orchids or fringed orchids, were previously included in the genus Orchis, which is a close relative. They are distributed throughout the temperate regions of the Northern Hemisphere. They are terrestrial and have tubercules.
Denge Wood is a wood located 8 miles southwest of Canterbury in Kent, England. The wood is owned by the Forestry Commission and the Woodland Trust. Part of the wood is also privately owned. Much of Denge Wood is classified as ancient semi-natural woodland suggesting it has been in existence since at least 1600AD and probably longer.
Platanthera chlorantha, commonly known as greater butterfly-orchid, is a species of orchid in the genus Platanthera. It can be found throughout Europe and Morocco. The name Platanthera is derived from Greek, meaning "broad anthers", while the species name, chlorantha, means "green-flowered".
Dactylorhiza maculata, known as the heath spotted-orchid or moorland spotted orchid, is an herbaceous perennial plant of the family Orchidaceae. It is widespread in mountainous regions across much of Europe from Portugal and Iceland east to Russia. It is also found in Algeria, Morocco, and western Siberia.
Platanthera psycodes, commonly called lesser purple fringed orchid or small purple-fringed orchid, is a species of orchid, genus Platanthera, occurring from eastern Canada to the east-central and northeastern United States. It is imperiled in Illinois, Tennessee, North Carolina, and Kentucky.
Platanthera transversa is a species of orchid known by the common names royal rein orchid and flat spurred piperia.
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 occurs in eastern Australia and one occurs in eastern Australia and New Zealand. Orchids in this genus as well as the hammer orchids (Drakaea) are pollinated by male thynnid wasps.
Monawilkin is a townland in the West Fermanagh Scarplands in the Civil Parish of Inishmacsaint, Barony of Magheraboy, Northern Ireland. The townland has an area of 85.1947 hectares and has previously been referred to as Meenwilkin (1817) and Munadh Wilkin. Monawilkin is the best example of unimproved calcareous grassland in Northern Ireland. This differs from other Sesleria-dominated grasslands in the UK in that it also includes species such as Euphrasia salisburgensis (eyebright). Monawilikin is also an important orchid site, contains the best inland site for moths and butterflies in Northern Ireland, and is the only Northern Irish site for Cupido minimus, the small blue butterfly. Consequently, this area was designated as a special area of conservation (SAC) and area of special scientific interest (ASSI). The Monawilkin SAC land cover comprises 3% water bodies, 5% bogs, marshes, and fringe water vegetation, 13% heath and scrub, 50% dry grassland, 14% humid grassland, and 15% broad-leaved woodland.
Talsi rolling hills is a nature park in the middle of Talsi Municipality. It is located in the north-western part of Vanemas pauguraine and includes the highest part, administratively belongs to Laidzes, Laucienes and Lībagu parishes. The protected area was established in 1987 to protect one of the North Kurzeme Uplands and highest part of the Elder Hill. It is most diverse areas in terms of natural conditions in the Latvia north-east, with a distinctly hilly terrain and several small but deep lakes. Scenic area. Natura 2000 territory. Many Latvia rare and protected plant and animal species. In total 24 species of flora (1) and fauna (23) are protected under EU Nature directives.
The pollination of orchids is a complex chapter in the biology of this family of plants that are distinguished by the complexity of their flowers and by intricate ecological interactions with their pollinator agents. It has captured the attention of numerous scientists over time, including Charles Darwin, father of the theory of evolution by natural selection. Darwin published in 1862 the first observations of the fundamental role of insects in orchid pollination, in his book The Fertilization of Orchids. Darwin stated that the varied stratagems orchids use to attract their pollinators transcend the imagination of any human being.
