I've managed to identify a Drosera Binata seedling and quite possibly some Drosera Spatulata seedlings as free loaders from a pot of Sarracenia that I bought a few months ago. There is just one plant however that I have not been able to identify. It looks like small grass.
Could it be some kind of Utricularia. I haven't seen it flower yet so I can't identify it as well.
