Hi Sally, Do you know where on Flagstaff your friend found the Myriophyllum. I mentioned it to Bill Hanson of Florida Power and Light and he is very interested. I did wetland surveys on Flagstaff years ago now. The work focused on the wetlands around the lake, but I did note aquatics. I had Myriophyllum on the species list, but had not speciated it. I haven't yet had a chance to go through my notes and see where on the lake I found it, but don't remember seeing much there at that time. Is it too late now in the season to positively id it? If not, I may try to locate some this fall.
