Are the inflated stems in a wheel around the inflorescence?  If so, it's
U. inflata or U. radiata.  U. inflata seems to be commonly cultivated by
CP enthusiasts, but I am told that U. radiata is an annual and is not
amenable to long-term cultivation.

The new second edition of Donald Schnell's _Carnivorous Plants of the
United States and Canada_ (Timber Press) has a nice chapter on Utricularia
with a key to the species.
