The Crane-fly Orchid (''Tipularia discolor'') is a perennial terrestrial woodland orchid, a member of the Orchidaceae.〔 It is the only species of the genus ''Tipularia'' found in North America. It occurs in the southeastern United States from Texas to Florida, the range extending north into the Ohio Valley and long the Appalachians as far north as the Catskills. There are also isolated populations in Massachusetts and in the Great Lakes region.〔(Flora of North America v 26 p 624, ''Tipularia discolor'' )〕〔(Biota of North America Program, county distribution map )〕 ''Tipularia discolor'' grows a single leaf in September that disappears in the spring. The leaf is green with dark purple spots. The flower blooms in mid-July to late August. The roots are a connected series of corms. Its roots are edible. They are starchy and almost potato-like. The plant is pollinated by noctuid moths, by means of flowers which incline slightly to the right or left, so the pollinaria can attach to one of the moth's eyes.〔(【引用サイトリンク】 Tipularia discolor )〕 Image:Tdiscolorgroup.JPG|Growing in large clonal group Image:TipDiscolor26Feb03.jpg|''Tipularia discolor'' colony, with seed pods, Florida, February.
