Flatwoods, pineywoods, pine savannas and longleaf pine-wiregrass ecosystem are terms that refer to an ecological community in the Southeastern coastal plain of North America. Flatwoods are an ecosystem maintained by wildfire or prescribed fire and are dominated by longleaf pine, and slash pine in the tree canopy and saw palmetto, gallberry and other flammable evergreen shrubs in the understory, along with a high diversity of herb species. It was once one of the dominant ecosystem types of southeastern North America. Although grasses and pines are characteristic of this system, the precise composition changes from west to east, that is, from Texas to Florida. In Louisiana, savannas even differ between the east and west side of the Mississippi River. The key factor maintaining this habitat type is recurring fire. Without fire, the habitat is eventually invaded by other species of woody plants.
Platanthera praeclara, known as the western prairie fringed orchid and the Great Plains white fringed orchid, is a rare and threatened species of orchid native to North America.
Platanthera leucophaea, commonly known as the prairie white fringed orchid or eastern prairie fringed orchid, is a rare species of orchid native to North America. It is listed as a threatened species in the United States on September 28, 1989. The IUCN does not currently recognize it as being at risk.
Coeloglossum is a genus of flowering plants in the orchid family Orchidaceae. It has long been considered to have only one species, Coeloglossum viride, the frog orchid. Some recent classifications regard Coeloglossum as part of the larger genus, Dactylorhiza, so that C. viride becomes Dactylorhiza viridis. Other sources continue to keep Coeloglossum viride separate.
Cephalanthus occidentalis is a species of flowering plant in the family Rubiaceae, that is native to eastern and southern North America. Common names include buttonbush, common buttonbush, button-willow and honey-bells.
Platanthera ciliaris, commonly known as the yellow fringed orchid, yellow-fringed orchid, or orange-fringed orchid, is a large and showy species of orchid. It grows in "acid soil of hillside seepage bogs" in the longleaf pine landscapes of the Gulf Coast of the United States. Like many species in these habitats, including flatwoods, it is dependent upon recurring fire to create open conditions. Further north it is found in bogs, but even here it may be dependent upon fire to create open conditions.
The genus Platanthera belongs to the subfamily Orchidoideae of the family Orchidaceae, and comprises about 100 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.
Eurybia radula, commonly known as the low rough aster or rough wood aster, is an herbaceous perennial in the aster family. It is native to eastern North America where it is present from Newfoundland and Labrador in the far northeast of Canada, west to Ontario and south to Kentucky and Virginia in the United States. The low rough aster is also present on the French overseas territory of St. Pierre and Miquelon just south of Newfoundland. It typically grows in wet soils in a wide variety of habitats from bogs and fens to creek shores to ditches. Although it is not considered threatened over most of its distribution, it is imperiled or possibly extirpated over much of its range in the United States. Its flower heads emerge in the late summer to early fall and show pale blue-violet rays with yellow centres.
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.
Solidago rugosa, commonly called the wrinkleleaf goldenrod or rough-stemmed goldenrod, is a species of flowering plant in the sunflower family (Asteraceae). It is native to North America, where it is widespread across eastern and central Canada and the eastern and central United States. It is usually found in wet to mesic habitats.
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.
Pogonia ophioglossoides, the snakemouth orchid or rose pogonia, is a species of orchid occurring from central Canada to the east-central and eastern United States. It is the type species of the genus Pogonia. It is pollinated by bees. This species occurs in wet habitats. In the north, the habitat is typically fens but sometimes also bogs. Further south, along the Gulf Coast, it is a species of wet pine savannas and flatwoods.
Platanthera cooperi is an uncommon species of orchid known by the common names Cooper's rein orchid and chaparral rein orchid.
Bayshore Blufflands State Natural Area is a Wisconsin Department of Natural Resources-designated State Natural Area of significant note for its grand scenery, unusual geology, rare plant and animal species. Containing more than 7 miles (11 km) of the Niagara Escarpment, the Bayshore Blufflands is an ecologically complex site with a diversity of plant communities both above and below the escarpment and a series of seeps and springs at the base of the bluff's talus slopes.
Platanthera obtusata, common name blunt-leaved orchid or small northern bog orchid, is a small species of orchid in the genus Platanthera. It widespread across much of the colder regions of the Northern Hemisphere, though rare in some parts of its range. Two subspecies are recognized:
Styrax americanus, the American snowbell or mock-orange, is a plant species native to the southeastern United States and the Ohio Valley. It has been reported from Texas and Florida to Virginia and Missouri. It generally grows in swamps and on floodplains and in other wet locations.
Quercus sinuata is a North American species of oak comprising two distinct varieties, Quercus sinuata var. sinuata and Quercus sinuata var. breviloba. Morphologically intermediate forms may occur where range overlap brings the two taxa together. Quercus sinuata var. breviloba is native to central and north central Texas, south central and southwest Oklahoma, and to Coahuila, Nuevo León, and Tamaulipas in northern Mexico. Quercus sinuata var. sinuata is native to the south-central and southeastern United States from central Texas and southwestern Arkansas to the Carolinas. Their respective ranges intersect in the Hill Country of central Texas, where streams flowing through dry, brushy limestone hills create a mosaic of wet and well drained habitats.
Hypericum canadense, known as Canadian St. Johns-wort, lesser St. John's wort, and lesser Canadian St. Johnswort, is a flowering plant in the genus Hypericum. It is a yellow-flowering annual or perennial herb native to North America and introduced to Ireland and The Netherlands. The specific epithet canadense means "Canadian".
Platanthera dilatata, known as tall white bog orchid, bog candle, or boreal bog orchid is a species of orchid, a flowering plant in the family Orchidaceae, native to North America. It was first formally described in 1813 by Frederick Traugott Pursh as Orchis dilatata.
Platanthera integrilabia, commonly called white fringeless orchid, is a species of flowering plant in the orchid family (Orchidaceae). It is native to the Southeastern United States. Its natural habitat is in boggy acidic seeps and flats, usually in partial open sunlight.
