Once it was called a 'albiflora'
and today it's called a hybrid'
There are two train of thoughts!
It is thought that back in 2016 perhaps there had been some sort of interference with the plants rhyzome to take on this "white" effect which may have later corrected itself to how it should have been.
Or the only other explanation I can think of is that the 2016 plant died off and a new plant has grown in its place. This could well be the more likely because in 2017 all I had to show was a seedling (without inflorescence) which is shown in the photo lower down, and in 2018 the same plant was still maturing and again never produced inflorescence, although I had started to notice it was very dark (purple) at the base of the stem.

And this is as good as it got!
(2019 Update) And would you ever believe what was the Albiflora in 2016 has come through this year as a hybrid (Epipactis schmalhauseneii) and shown here in the next photo......
from the 55 populations - This is how the albiflora came through this year
The plant came through but yet again had reverted back to a seedling state which never achieved inflorescence
