As usual your input is invaluable.

I've got Casper's monograph but my German is too poor to understand it all.

However, a question arises.

As you may recall, I'm part of a UK (now World Wide) scheme to build
National Collections of specific genera; I hold the Pinguicula
Collection. I'm happy to name all P. moranensis "forms/sub-species"
under the moranensis name but it seems that data is then lost. The
plants arrive with an associated "form/sub-species" name. So what is
the recommended or scientific (or best non-scientific) way to retain
the "form" when labelling the plant - or does one just drop the
form/sub-species and not care?
