Ispahan,
Yes, those are Pinguicula 'Titan' in one tray, with good light, always distinctive. Several trays of Pinguicula esseriana, Pinguicula ehlersiae, Pinguicula jaumavensis, and Pinguicula debbertiana. Also there is, at least, an entire tray of Pinguicula gigantea that seems to have done very well.
My collection has never been entirely organized. I've had groups of various species, hybrids, unnamed clones, and cultivars mixed throughout my various shelves and trays. It has often complicated my keeping track of how many of each plant that I have, but presently I am thankful for this disorganized organization, plants that didn't fare too well under present circumstances appear to have done better in one tray or location than they have in others. For example, Pinguicula moctezumae has survived in three pots, all in the same tray. I enjoy this species very much and hope I can successfully rehabilitate these extremely weakened survivors. There are several species, hybrids, and unnamed clones that I have yet to find a surviving plant of, once I've gone through my entire collection and rehabilitated it, I will know then which plants I will need to seek to reacquire.

I will try to compile these observations into a more comprehensive format (added to the page I already created), once I have finished with all the trays.
