Email response from the biologist said: 'It's broadleaf pondweed, I'll have to check for genus and species,....I've never been able to find any for sale. Genus might be Potamogeton, but not sure off the top of my head.'
I guess the point here may be that it is difficult to find any broadleaf pondweed for sale. If we could find a source that sells any of the genus or species of the broadleaf, that may be of benefit to us.
Do you think we could start with trying to find a supplier of the broadleaf and if more detailed info is needed I'll certainly get it?
