The kind only counts 2 species inhabiting the temperate and cool zone of the Northern Hemisphere. One species in Europe – green tongue (Coeloglossum viride), which grows almost all over the continent, except the Mediterranean basin. Most North American researchers include tongues in the type of knee-length (Platanthera).

Information about the pollination of this inconspicuous orchid is very scarce. Wasps have been observed on its flowers (Cryptus sp. i Ichneumon sp.), beetles (Cantharis sp.) and planters (Tenthredopsis sp.) with pollinia stuck to the body. Presumably, these insects can act as pollen carriers. Perhaps butterflies also occasionally smell their tongue, what are the reasons for hybrids with species pollinated by this group of insects, e.g.. with a roll.
