About this species

Dactylorhiza purpurella is difficult to distinguish from other marsh orchids, such as D. praetermissa, and was not described as a separate species until 1920. Northern marsh orchid can be recognised by its lip marked with dark spots and lines that do not usually form loops, as well as by its vivid purple-violet flower colour.

Dactylorhiza is one of the most complex orchid genera. It comprises about 50 often poorly defined species. Most occur in Eurasia, but two species are also found in North America.

The name Dactylorhiza derives from the Greek words daktylos meaning finger and rhiza meaning roots, referring to the finger-shaped underground tuber typical of members of this genus.

Genus: 
Dactylorhiza
