ON - Algonquin Park, Grassy Bay

Found these on a canoe trip in August. They were everywhere in Grassy Bay. Growing with Sarracenia purpurea and well as an Utricularia sp. Was very excited to have see carnivorous plants out in the wild, and in such large numbers as well. We were expecting to see S. purpurea, and the Drosera intermedia was a nice surprise. Photos taken with an Olympus tough camera, with the macro setting. No enhancements done except for what the camera does automatically. Also, please correct me if this is actually D. rotundifolia. I didn't key the flowers out, I'm going based on the leaf morphology.

This is D.intermedia for sure.
Looking at this pic below I can see also some leaves of D.rotundifolia in the top left corner.
The small "leaves" growing among the peat and algae could well be U.cornuta.
There is some Utricularia visible in the lower right corner. It could be U.intermedia (or U.minor) or some related species. Impossible to tell without looking at the flower or some material under the microscope.
Many CPs share the roughly the same habitat so it is not unusual to find many different species at the same site. In fact on this picture I can't see any higher plant that is not carnivorous.

Amazing! I see that now. Thank you. I did see some Utricularia flowering there as well (photos below). Would the Utricularia "leaves" growing in the peat be attached to the same individuals as the the ones growing in the water?

Based on what I've observed in the park, U. cornuta is the most likely choice for the terrestrial leaves growing in the peat, it's extremely abundant in these types of marginal bogs (some of the largest flowerings of this species I've ever seen have been in Algonquin in July). The aquatic species you posted isn't U. cornuta, Eric may know what it is (I'm not great with the yellow flowered Utrics).

I can't tell exactly what species it is from the flower on your picture. It is maybe some form of U.gibba if it is small or it could be U.intermedia if it is about 1cm wide. Not sure. I would need to see the spur and other details better.
It is not unusual to find 3 or more Utric species growing intermingled. So the stolons and flowers at one spot don't necessarily belong to the same species. The aquatic species are usually free floating, the semi-aquatic species (like U.minor and U.intermedia) usually have some dimorphism: Whitish stolons with many traps that grow into the detritus and green stolons with few or no traps growing near the water surface. Terrestrial species like U.cornuta stick to the peat/sand, but you may see some thin stolons growing a bit into the water.

This cannot be intermedia because intermedia is much bigger in the stem structure and the bladders are underground while some flat leafed stem is on the surface. Also not Utricularia minor because the flower is completely different. Also not cornuta because the flowers on that has a very long spur which is not present on this picture.
