Tentatively identified as Northern Marsh Orchid, Dactylorhiza purpurella. Confirmation welcome. [Update: This site http://www.thewesternisles.co.uk/wildflowers/northern-marsh-orchid-x-heath-spotted-orchid.htm suggests Northern Marsh Orchid does not have spotted leaves (which these plants do) so it may be a hybrid, perhaps Northern Marsh x Heath Spotted Orchid.]
