    In the paragraph about P. agnata, it says that it doesn't form a true winter succulent. The only thing that happens is the leaves get smaller, but it's still carnivorous.

    Even SG is wrong now and again .

    Every P. agnata form I had went into succulent phase. Every Mexi-Ping I have had went succulent in some capacity.

    Pyro is correct. Every Mexican ping will change its leaf form throughout the course if its life. Whether or not it actually produces true succulent, non-carnivorous leaves or just much smaller leaves with carnivorous glands depends mostly on individual growing conditions. As a rule, the dryer they are kept the more likely the leaves will be succulent and non-carnivorous. There are some forms which, if kept consistently damp, will merely produce smaller, carnivorous leaves. However, even those forms which still produce small carnivorous leaves no longer seem to actively capture prey (they do occasionally, but it is a relatively rare occurence).

    The only Mexican form in which I have never observed a change in leaf form is Pinguicula emarginata. I am not saying that P. emarginata does not change leaf form, just that I have never seen it.

    I have a P. agnata in a terrarium and it has not had a suculent stage so far. I keep it on a constant 14 hour light schedule. My P. esseriana does though. The plant posted here looks a lot like my P. agnata also so it my be that as well.

    Here is my P. agnata with a photo of Summer and Winter foliage. If you zoom in, you can see that the Summer foliage is very sticky while the Winter foliage has no sticky glands, just hairs. The Winter rosette is also a little tighter and smaller. The black specs on the Winter photo are not prey; it is incapable of catching prey at the moment.
