ID for Crypt

I was in the aquarium store and spied a new Crypt specimen that I didn't
have and I was wondering if anyone can help ID it. The leaf structure is
very typical for Crypt wendtii but the leaf stem is about twice as thick
and very white. The roots had a thickened rhizome that was cut to propagate
the plant. Perhaps this is not a Crypt at all... ??
