Voyria, commonly known as ghostplants,[1] is a genus of 20 species[2] of herbaceous perennial plants, belonging to the family Gentianaceae.

Their roots are thick and densely clustered, forming a "birds nest" that house their fungus host.

The flowers can vary in colour, with white or yellow predominating, and blue and pink also occurring.

Like all myco-heterotrophs, they are capable of living in very dark conditions, such as the floor of deep forests, because they no longer derive energy from sunlight.

The latter, which contains a majority of the species, is characterized by highly reduced features, lacking both stomates and a continuous vascular cylinder.
