Jan,

I'm glad I could be of help in this fantastic study of yours Jan!
I just wish I'd preserved some of those G.violacea pitchered leaves when I
saw them. In fact, the first I saw were in plants cultivated by Ivan
Snyder in L.A. So if you're out there, Ed Read, tell Ivan to preserve in
alcohol the next pitchered leaves he sees on his plants and send them to
Jan!! That also goes for everybody out there cultivating Genlisea!
Congratulations Jan!!!
