For quick identification purposes in the Western Isles there are two main orchid species with rich colour like this, the Early Marsh-orchid and the Northern Marsh-orchid.

The Early Marsh Orchid only likes non-acid soil (basic) preferably the lime-rich sandy soil of the machair, like Riof or Northton. Northern marsh orchid will grow in soils which are quite acid as well as the lime ones, and is often found in damp grassland and at roadsides.

Neither Early Marsh-orchid or Northern Marsh-orchid have spotted leaves (unless they have crossed with another species)

Early Marsh-orchid

In the Early Marsh-orchids the bottom part of the florets are narrow-looking with the sides pulled back

.Those of the Northern Marsh orchid are not "pulled back" and the bottom part of the floret appears diamond-shaped
