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.

Further north it is found in bogs, but even here it may be dependent upon fire to create open conditions.

Platanthera hyperborea, the northern green orchid, is small orchid found only in Greenland, Iceland, and Akimiski Island in Canada. Numerous authors cite the species as widespread in other parts of Canada and also in the United States; such populations are more correctly referred to as Platanthera aquilonis.
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:

Platanthera azorica, commonly known as Hochstetter's butterfly orchid, is a species of orchid in the genus Platanthera. It was "rediscovered" in 2013 on a single volcanic ridge on the central Azores island of São Jorge, and "is arguably Europe's rarest bona fide orchid species." While P. azorica was previously considered by some sources to be the same as Platanthera micrantha, the 2013 discovery triggered a thorough analysis of historic and current data and specimens, resulting in three species identified.
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.
