Tricksy pitchers:
You know, if someone showed
me this plant in their collection, and asked me what I thought it
was, I think I would
be baffled. The leaf venation reminds me of
Sarracenia alabamensis subsp. alabamensis, but the broad pitcher opening looks more
like Sarracenia flava. If I were being careless, I might think
that the arched lid suggested some S. minor introgression, too.
(I'm hesitant to guess S. oreophila as being a parent of
cultivated plants since most growers do not have it.)
I'm not sure what I would guess--maybe
S. alabamensis subsp. alabamensis × oreophila, but I don't know. My point
is simply that it is dangerous to try to identify some plants in
cultivation. Even pure species can be confusing, especially if you
don't know if they are pure or hybrids.
