I was camping last week in the Lake Tahoe area and while wading in a stream came across some utric growing in the water. (Boy was I surprised!

It was not flowering but in some areas the traps had turned a deep purple (as describe in other recent posts). The only free-floating aquatic utric the SG described which fit the description and comes from this area was u. macrorhiza. Are there any others that might be growing here?
