Dear Jos, Juerg, Rick, Fernando & al.,

If it does *not* have a wing or other margin rudiments it seems to be
closer to _Cephalotus_ (peltation) than to _Sarracenia_ (lateral margin
coalescence), however. Certainly the transversal zone (if present) is not a
lid in the _Pinguicula_ pitcher (but rather just the ventral, adaxial
pitcher wall), but I assume the _P._ pitcher does not have a lid, anyway.

>btw who is casper?

Prof. Dr. S.Jost CASPER from Jena, Germany, is perhaps the most famous and
certainly a most knowledgeable botanist working on _Pinguicula_. His
"Monographie der Gattung _Pinguicula_" (1966) is a milestone.

Thank you both (Jos and Juerg) for your support.

Do you (Fernando) have pictures or preserved material of these
malformations? Thanks for the information, anyway.

Kind regards
