Hi Sue-- I already have one friend (wo is not in the least botanically inclined, but who is a great salt-water fisheries biologist) who found this at Flagstaff Lake(M. heterophyllum, I believe) She is sending me some for the herbarium next spring when it is absolutely IDable (someone from the "lakes survey"{?} tentatively ID it--but I thought it was great that she observed it to be something that she had never seen before and so took action. Hope you are alive and well!
