[A 1998 Nfld. report of Dryopteris ×uliginosa auct. non (A.Braun ex Döll) Kuntze ex Druce from TNNP, Brouillet & Charest (MT), is referred to an unnamed hybrid of D. carthusiana × D. cristata, originally reported as D. ×uliginosa, rare in boreal eNA (Cody & Britton, 1989).  However, the name Dryopteris ×uliginosa was described from European specimens as a hybrid of D. cristata × D. spinulosa, thus it is not considered synonymous with the North American hybrid of D. carthusiana × D. cristata.]
