I'm probably over analyzing this, but I have a developing pitcher on my N. ventricosa (it's inflating) and the lid doesn't seem to be growing with the pitcher body. It is already detached from the future peristome.
I can post pics...if necessary but I was really just curious.
I haven't posted on here in a while, but I'm at UCLA now and I only brought two n. ventricosa, two d. capensis, and a flytrap (which is almost dead because of a light issue I believe). My window is not sunny at all, so I supplement with a compact flourescent in my desk lamp...ha.
