Galeola is a genus of orchids (family Orchidaceae) belonging to the subfamily Vanilloideae. [1]

Contents

All species in this genus are myco-heterotrophic, i.e. they are parasitic upon fungi. The genus is spread throughout southeast Asia (from India 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.

At present, there are 6 currently recognized species: [2]
