  • Question

    Hello, I would love your help with this one, please. It has stumped the Native Plants of New England Facebook group, which is a rare thing. It's rooted in my pebbly, 4-seasons brook in Windsor NH. It was completely submerged. These photos taken with submersible camera on May 31, 2020 No flowers or fruits observed. Photos attached Thank you, Laura Costello ljcost@gmail.com

    Answer

    Dear ljcost, good morning. I can't be certain--but if you get back to this area, unearth a little of the soil around the underground storage organ. This plant likely has a large rhizome that would confirm it as a species of Nuphar (pond-lily). The leaves do appear like the submersed ones of this genus. Without the rhizome, I won't be able to be certain.
