Dendrophylax lindenii
 
Mounted on pine bark.
 
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 and Cuba.
Other common names include palm polly and white frog orchid.
 
The 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. The genus Dendrophylax was formerly known as Polyrrhiza.
