This photo was taken August 2005 in South Tweedsmuir park, in the valley below Crystal Lake. THese little plants and flowers were in a dense brown mat, with small white flowers that are visible in the picture. THe unusual part of these flowers is that all of them, and the mat underneath were completely underwater, not far under the water, maybe 1-2 cm. THe water was lightly flowing over the mat. I have not been able to ID these little guys and was hoping for others help! THanks Sincerely Jen COdy
Water Crowfoot (Ranunculus subgenus Batrachium). A difficult group to identify to species, but very easy to the subgenus. Possibly R. trichophyllus or R. circinatus, if they occurs in your area.
