OK Back to my problem. I went out this morning and got a sample of the evil weed. It has a small white flower when emerged. the leaves are smooth to the touch with 4-5 leaves in a whorl. It seems to grow in patches that are getting bigger and more widespread each year. What do you think. It really did not fit the description of Elodia or Hydrilla but the long stems of it growing in a mass looked like it. It must be something closely related. Chuck
