Hmmm, not sure what went wrong there. All fixed now!

For the moment, this has to be recorded as Myriophyllum sp, as there are no characteristics evident to confirm it to species.
A photograph later in the year, when flowering (or bud etc0 would help, also a count of how many leaves are in a whorl below water and how many in the truly emergent part of plant. Plus any other details you can capture in a photo.
