I would not be quick to reach this conclusion. In the past many growers
have reported difficulty with getting Dionaea to produce good pollen. This
occurred in plants that were known to produce pollen and did so at later
times once again. I think these failures were attributed to weak lighting
and/or not so great temperatures.
Perhaps, since yours is the first to even get this far (Congratulations!!!),
and it appears that much closer to Dionaea, it suffers from the same
malaise.
