taken from my diary of 18th July 2013 - please ignore were the red cross covers
The first photo I show will be the regular "Atrorubens" which here you can see in colour,
|40x Denticulation photo of "atrorubens" used as a supportive aid to identification (photo: Sean Cole)|
So this next photo is the Epipactis Helleborine denticulation photo:

With E. Helleborine which you can see in the above photo the teeth pattern is much more uneven with odd individual teeth or even small cluster rows appearing amidst a more regular section etc. Also you do not usually see the line of "purple" which is associated more with the atrorubens. You tend to associate the denticulation with straight transparent!
And finally I want to show a photo of what maybe a Schmalhauseneii hybrid and again a photo to help me in a supportive roll of trying to obtain identification.

And finally from the photo above you will see that it represents a more or less "in between of the previous two photos. The teeth are irregular but will get more regular rows in between the protruding teeth like we had with the atrorubens. Also if you do look very close again you should see a double row of teeth. Also sometimes but very rarely on the hybrid you can see a trace of purple colour at the bottom of the teeth (in 90% of cases they will be transparent like you get in E. Helleborine).
I am also very fortunate to have the following photos from Mike Wilcox which also show "denticulation (teeth patterns on leaf edges)" features:
|This is yet another examble of "denticulation" of the E. Helleborine (Photo: Mike Wilcox)|

This is a photo of a "green stemmed" = Helleborine parent influence, with
the obvious signs of atrorubens creeping in with the red/purple sheath to stem,
purple vertical lines, together with purple base and again the trailing
edge to basal.
