Which orchid species is commonly called the ghost orchid?

Dendrophylax lindenii is the orchid species commonly called the ghost orchid.

The ghost orchid is an epiphytic orchid native to Florida and Cuba. It usually grows attached to tree trunks and branches rather than in soil. Its reduced leaves and pale roots make the plant difficult to see, while its white flowers appear to float against the dark forest background.

The species has a long, narrow floral spur and is pollinated in Florida primarily by the giant sphinx moth, Cocytius antaeus. The orchid’s specialized habitat and difficult cultivation have contributed to its reputation as a mysterious and elusive plant.

The name “ghost orchid” can be applied informally to other orchids in different places, so the common name alone is not always taxonomically precise. Dendrophylax lindenii is the species most strongly associated with the name in North America.
