I admit that at work I do not have my references near, so I don't know
the meaning of "pleiochasial". But you are suggesting that in this genus,
what is widely regarded as the peduncle (the inflorescence from rosette
to calyx lobes) is actually the pedicel? And that the peduncle is
reduced or absent? You didn't nest parentheses properly above, so I don't
know what you do with "(enlarged) subtending bracts"...

This is an interesting idea... With _Pinguicula_, the absence of visible
bracts indicates the peduncle is actually a pedicel. Meanwhile, in something
like _Sarracenia_ with three bracts in a whorl, right by the five sepals,
the peduncle is truely a peduncle. Am I making sense?

Tom:

I've never bothered to store pollen because I've usually had enough plants
at hand in flower. How are you cold storing the pollen? Is the pollen
dry or moist. Some talk about drying the pollen using silica gel as a
dessicating agent, but I don't know how much abuse pollen can take.
