Dactylorhiza praetermissa, the southern marsh orchid or leopard marsh orchid, is a commonly occurring species of European orchid.
Dactylorhiza praetermissa grows to 70 cm (28 in) tall, with leaves generally unspotted. The flowers, appearing from May to July, are various shades of pink with variable markings. The basal lip of the flower is rounded.[2]
This species is able to form hybrids with other Dactylorhiza species, and crosses with Dactylorhiza fuchsii occur especially often.[3]
It is native to northern and central Europe (Britain, Denmark, Norway, Sweden, Germany, Netherlands, Belgium, France, Estonia and Latvia). It is also reportedly naturalized in Italy and in parts of Canada (Ontario and Newfoundland).[1][4]
This species is found close to water, in damp alkaline meadows, by ponds, lakes or reservoirs and in dune slacks.
The flowers of this species are pollinated by insects including the cuckoo bee and skipper butterfly.[5]
Dactylorhiza are known to be mycorrhizal generalists.[6] D. praetermissa has been shown to benefit from association with fungal species in the genus Rhizoctonia and others in the Tulasnellaceae family.[7][8]
