Here are a few Utricularia flowers from my collection. Not all were in flower at once. The U. fulva, U. calycifida, and U. asplundii are in flower (or working on being in flower) right now.
My Utricularia collection is a pretty big mess right now. Most have pot hopped into other pots.
This one is labeled as U. dichotoma, but it's lacking the skirt?
