The genus Dactylorhiza Necker ex Nevski in general, and the allopolyploids of the D. majalis (Rchb.) P.F. Hunt & Summerh. aggregate in particular, have long been an exceptional focus for both taxonomic and nomenclatural controversy within Orchidaceae subtribe Orchidinae; indeed, D. majalis itself was the subject of a recent successful proposal to conserve against three earlier, but less well-known, species names (Pedersen & al. in Taxon 52: 633–634. 2003). The many epithets generated within the D. majalis aggregate represent entities that are at best only subtly morphologically distinct (e.g., Bateman & Denholm in Watsonia 14: 347–376. 1983; Pedersen in Nordic J. Bot. 18: 289–310. 1998), reflecting their shared origins from hybrids between diploid ovule-parents of the D. maculata aggregate and pollen-parents of the D. incarnata aggregate (e.g., Heslop-Harrison in Jahresber. Naturwiss. Vereins Wuppertal 21–22: 20–27. 1968; Hedrén in Pl. Syst. Evol. 201: 31–55. 1996; Hedrén & al. in Amer. J. Bot. 88: 1868–1880. 2001).
