Platanthera Zijinensis
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 (along with the genus '' Habenaria''). They are distributed throughout the temperate regions of the Northern Hemisphere. They are terrestrial and have tubercules. The genomes of '' Platanthera zijinensis'' and ''Platanthera guangdongensis'' have been sequenced as model species to study partial and full mycoheterotrophy. Etymology Louis Claude Richard chose the name ''Platanthera'' for this genus; it comes from the Greek and means 'broad or wide anther', referring to the separation of the base of the pollinia in the type species of the genus. Richard felt that this characteristic distinguished the genus ''Platanthera'' from both the genus ''Orchis'' and the genus '' Habenaria''. However, toda ...

Platanthera Bifolia
''Platanthera bifolia'', commonly known as the lesser butterfly-orchid, 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. The name ''Platanthera'' is derived from Greek, meaning 'broad anthers', while the species name, ''bifolia'', means 'two leaves'. Identification 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 ...

Platanthera Clavellata
''Platanthera clavellata'', commonly known as the club-spur orchid or small green wood orchid, is a terrestrial orchid of North America. Description ''Platanthera clavellata'' plants are 4-16" tall. It is one of the smallest species out of the 32 species of Platanthera common in North America. The stem has several leaves attached of which all but the bottom-most one are greatly reduced in size. There are no branches and the stem terminates in a raceme of 5-20 flowers. The flowers are small and inconspicuous and consist of 3 petals and 3 sepals which look like petals. The petals/sepals are greenish to white or yellowish. The upper two petals and upper sepal form a hood and the two lateral sepals are bent forward like two small wings. The lower petal is longer and forms a lip at the front and a nectar spur at the back. Bloom time is mid to late summer. Distribution and habitat The plant will grow in moist and acidic soil and requires partial shade. It can grow in areas like mo ...

Platanthera Colemanii
''Platanthera colemanii'' is a rare species of orchid known by the common names Coleman's piperia and Coleman's rein orchid. It is endemic to California, where it is known from scattered occurrences along the Sierra Nevada and one disjunct location in Colusa County, California. It grows in coniferous forests and chaparral in deep sandy substrates. It was differentiated from the very similar '' Platanthera unalascensis'' in 1993.Coleman, R. A. (2002)The Wild Orchids of California.Comstock Publishing Associates, Cornell University Press, Ithaca. It grows erect to about half a meter in maximum height. The basal leaves are narrow and almost grasslike, measuring up to 16 centimeters long and no more than 2 wide. Leaves higher on the stem are much reduced. The upper part of the stem is a spikelike inflorescence of up to 100 small flowers. The unscented translucent green flowers have curved sepals and sickle-shaped, curving petals a few millimeters in length. The flower can be distingu ...

Platanthera Blephariglottis
''Platanthera blephariglottis'', commonly known as the white fringed orchid or white-fringed orchis, is a species of orchid of the genus ''Platanthera''. It is considered to be an endangered species in Connecticut and Ohio, a threatened species in Florida, Maryland and Rhode Island, exploitably vulnerable in New York, and susceptible to be threatened in Québec. ''Platanthera'' is a Greek word that means "flat" and "flower". For this use it means "wide or flat anthered". ''Blephariglottis'' is from ''blepharis'' which means "eyelash" or "fringed" and ''glottis'' for "tongue."

Platanthera Aquilonis
''Platanthera aquilonis'', the northern green orchid or north wind bog orchid, is a species of self-fertilizing orchid native to the United States and Canada with a widespread distribution across the two countries. Description ''Platanthera aquilonis'' is a small plant 5–60 cm in height. Flowers emerge in May and are present until August. These flowers are not showy and are generally a yellowish green color. The leaves are alternating and replaced by lenceloate bracts higher up on the stem. This orchid can be most easily identified by its forward rotated pollinia spilling over into the stigma and its rhombic to rhombic lanceolate lip. It is very similar looking to '' Platanthera huronensis'' but can be separated by the fact that ''Platanthera huronensis'' is whitish green whereas ''Platanthera aquilonis'' is just green or yellowish green in color.Coleman, Ronald A. The Wild Orchids of Arizona and New Mexico. Cornell University Press, 2002. Platanthera aquilonis is usually ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platanthera Psycodes
''Platanthera psycodes'', commonly called lesser purple fringed orchid or small purple-fringed orchid, is a species of orchid, genus ''Platanthera'', occurring from eastern Canada (from Manitoba to Newfoundland) to the east-central and northeastern United States (Great Lakes Region, Appalachian Mountains, and New England). It is imperiled in Illinois, Tennessee, North Carolina, and Kentucky. The botanical name, specific epithet ''psycodes'' is a misspelling of ''psychodes'', which means "butterfly-like", probably alluding to the shape of the flowers. Like many other orchids it is a plant of wet habitats: sedge meadows, flatwoods, sphagnum bogs, cedar or alder swamps, on stream edges or the moist edges of coniferous forests. It is occasionally found in wet swales adjoining freshwater sandy beaches. Preferring cooler habitats, its range is being pushed northwards as global temperatures warm.

The Plant List
The Plant List was a list of botanical names of species of plants created by the Royal Botanic Gardens, Kew and the Missouri Botanical Garden and launched in 2010. It was intended to be a comprehensive record of all known names of plant species over time, and was produced in response to Target 1 of the 2002–2010 Global Strategy for Plant Conservation (GSP C), to produce "An online flora of all known plants". It has not been updated since 2013, and has been superseded by World Flora Online. World Flora Online In October 2012, the follow-up project World Flora Online was launched with the aim to publish an online flora of all known plants by 2020. This is a project of the United Nations Convention on Biological Diversity, with the aim of halting the loss of plant species worldwide by 2020. It is developed by a collaborative group of institutions around the world response to the 2011-2020 GSPC's updated Target 1. This aims to achieve an online Flora of all known plants by 2020 ...

Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...
