'''''Platanthera leucophaea''''', the '''eastern prairie fringed orchid''', is a rare [[orchid]] native to [[North America]]. It is listed as a threatened species in the [[United States]], the [[IUCN]] does not recognise it as being at risk.<br />
<br />
''P. leucophaea'' arises from a fleshy [[tuber]]. The plant can grow up to three feet (91 cm) tall. The [[inflorescence]] is large and showy and may have up to 40 white flowers. The leaves are long and thin. It is distinguished from ''[[Platanthera praeclara]]'', the western prairie fringed orchid, by its smaller flowers (less than one inch (2.5 cm) long), more oval petals, and a shorter nectar spur. The eastern prairie fringed orchid is a long-lived perennial plant. Its tuber rootstalk helps it survive grass [[fire]]s. Fires and rain stimulate the plant to grow and flower. The plant emerges each year in May and flowering begins by late June. The flowers are pollinated at night by large sphinx moths. <br />
<br />
''P. leucophaea'' is found in moist to wet tallgrass [[prairie]]. In the eastern part of its range, it is found in wet sedge meadows. Historically, the eastern prairie fringed orchid occurred east of the [[Mississippi River]] and in [[Iowa]] and [[Missouri]]. Scattered populations are found in [[Illinois]], [[Indiana]], [[Iowa]], [[Maine]], [[Michigan]], [[New York]], [[Ohio]], [[Virginia]], [[Wisconsin]], and [[Ontario]], [[Canada]]. A historic record exists for [[Choctaw County, Oklahoma|Choctaw County]], [[Oklahoma]]. The plant has not been observed in Oklahoma in the past 150 years. The major factor in the decline of the eastern prairie fringed orchid has been a loss of habitat due to grazing, fire suppression, and agricultural conversion.<br />
