Orchid Observers Talk
The notes suggest that these are hybrids between D.fuchsii and O.maculata, I have entered as O.fuchsii as on the label
Not chalk, Breconshire, so going for Marsh Fragrant.
White form of D.praetermissa is a bit of a guess. Could also be fuchsii with faded spots on leaves, or a hybrid!
Have guessed Greater Butterfly but could be Lesser.
Think Common Spotted as lip quite indented.
