Discussion

Subspecies eucosma is known from limestone barrens in western Newfoundland and Anticosti Island (K. M. Urbanska 1983). It is morphologically similar to subsp. pulcherrima; the two are separated mainly by the presence of prominent flags on cauline leaves in subsp. pulcherrima and their absence in subsp. eucosma.
