Yes, I occasionally get an intermediate between the carniverous and
non-carniverous leaves. I was referring here to intermediates between
juvenile carniverous leaves and adult carniverous leaves, in which the
"jump" is made immediately, unlike sarracenia which just gradually
develops leaves more and more like the adult leaves until the transition
is complete. (Darlingtonia also makes a "sudden switch" like this).
