Abstract
A new species of Achnanthes, A. scotica, is described from Lochnagar in the Cairngorm Mountains, Scotland. Three new varieties, A. altaica v. minor, A. austriaca v. minor, and A. austriaca v. alpina and one new form, A. marginulata f. major, are also described from sites in the Cairngorms and elsewhere. Modern and fossil distributions of these taxa in acid upland oligotrophic UK lakes are evaluated.
