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.


At present, there are 6 currently recognized species:[2]
  1. Galeola cathcarthii Hook.f. (ThailandMyanmarIndiaAssamBhutanSikkim)
  2. Galeola faberi Rolfe (ChinaAssamNepalVietnamSumatra)
  3. Galeola falconeri Hook.f. (IndiaTaiwanAssamBhutanNepalThailandVietnamChina)
  4. Galeola humblotii H.G.Reichb. (MadagascarComoros)
  5. Galeola lindleyana (Hook.f. & J.W.Thomson) H.G.Reichb. ( BhutanChinaIndiaSumatraVietnamAssamNepalTaiwan)
  6. Galeola nudifolia Lour. (1790) (ChinaIndiaIndonesiaMalaysiaPhilippinesThailandVietnamAssamLaosCambodiaBurmaNew Guinea)
