Narrow-Leaved Marsh-Orchid (Dactylorhiza traunsteineri) is very rare, being reported from only three sites within Northern Ireland.

This orchid is a member of the very confusing Marsh-Orchids which include the Northern and Western Marsh-Orchids.

Some botanists regard this species as merely a subspecies of the Western Marsh-Orchid (D. majalis). Like that species it has a 3-lobed lip to the flower, but the lobing is much more pronounced, something like that of the Common Spotted Orchid (D. fuchsii). (Unlike that species, the stem is usually hollow and the flowers can range from a dark purple to a pale lilac).
