[gobotany.nativeplanttrust.org] Morphological Variation: Potamogeton natans, like many other species of pondweed, is capable of tremendous morphological variation. In still water its leaf blades are broad and subcordate at the base. ?In flowing or tidal water, the leaf blades become narrower and the bases tapered. (link added by Mary Ann Machi)
