lapponica (synonym Dactylorhiza lapponica), the Lapland marsh-orchid, is an orchid native to parts of Europe and Siberia, including the Pyrenees, Alps, and Carpathians and across middle Europe, Scandinavia, and European Russia [1][2][3][4] The subspecies grows on calcareous soils, including fens and areas with mobile groundwater.

[5] It was originally published and described by Lars Levi Laestadius and Carl Johan Hartman as Orchis angustifolia var.

Fl., edition 4 on page 281 in 1843,[6] but it was then re-named as Dactylorhiza lapponica in Nom.

[7] The naming of species and subspecies in genus Dactylorhiza has gone through many revisions over the decades,[5] and D. majalis subsp.

Plants identified as D. traunsteineri in Britain and Ireland are now considered to be Dactylorhiza majalis subsp.
