Dendrophylax lindenii (the American ghost orchid), the ghost orchid (a common name also used for Epipogium aphyllum) is a perennial epiphyte from the orchid family (Orchidaceae). It is native to Florida, Cuba and the Bahamas. Other common names include palm polly and white frog orchid. Since the roots of this orchid blend so well with the tree, the flower often seems to be floating in midair, hence its name of "Ghost Orchid".
Its specific epithet "lindenii" is derived from its discoverer, the Belgian plant collector Jean Jules Linden who saw this orchid for the first time in Cuba in 1844. Much later it was also discovered in the Everglades in Florida.
Epipogium aphyllum (the Eurasian ghost orchid), is a hardy myco-heterotrophic orchid lacking chlorophyll. (Wikipedia)
