Comments: These floating-leaved aquatics were found within the Magnuson Park reconstructed wetland areas but not in adjacent Lake Washington. The hairs/trichomes on the upper leaf lobes appeared unicellular at 20x magnification. I did not find any sporocarps attached to the individuals I observed. Identification confirmed by Ben Ledgler.
