Discussion

The corolla lobes of subsp. detonsa and subsp. yukonensis are proportionately narrower than those of the other Gentianopsis taxa in the flora area and taper to a more nearly acute apex than those of any other taxa except G. macrantha.

Plants from arctic Canada and Greenland do not ap­pear to be separable from those from Iceland, the prov­enance of the type, nor from plants from Norway. If representatives of Gentianopsis detonsa in any other part of continental Europe are considered taxonomi­cally separable, subsp. detonsa in the flora area is appro­priately retained in the autonymic subspecies.
