Galeola

Galeola is a genus of orchids (family Orchidaceae) belonging to the subfamily Vanilloideae.[1]
All species in this genus are myco-heterotrophic, i.e. they are parasitic upon fungi. The genus is spread throughout southeast Asia (fromIndia to China to New Guinea) as well as Madagascar and Comoros.[2]
Galeola is of biological interest because of its exclusive myco-heterotrophic nature and its seeds. The seeds are the biggest orchid seeds in the world. They are winged, which is also extraordinary for an orchid.
