Total = 20 genera (including Serapias but excluding Epipogium);
50 unequivocal species + 2 prospecies + 2 extirpated species + 2 species found
only in the Channel Isles
Note
that several of the species have recently been, or are, the subject of
nomenclatural debates focused on the rules of priority (e.g. Epipactis
purpurata, Pseudorchis albida, Platanthera
chlorantha, Gymnadenia densiflora,
Dactylorhiza viridis (also the
Continental D. majalis), Neotinea
maculata, Ophrys fuciflora).
