Ever since I first heard about "winter" leaves on Mexican Pings being non-carnivorous and without trapping glands I have been searching for these elusive leaves.
Below is a recent image of a Pinguicula 'Titan' with winter growth as an example. It seems easy to see that the leaves are still glandular. All of my Mexican Pings appear to maintain some degree of glandular trapping even in their "winter" leaves, the exception being the ones that go "underground".
