These three plant types were noted to occur in a ground water fed stream. One of them is for sure watercress and I am wondering if the second plant may be a similar species to watercress. The third plant was more like a pond lily floating on the surface. All these plants were found in an agricultural drain. The two watercress like plants had advantageous roots while the pond lily had one root. Thanks for any help you can provide in the id of these plants.
