I'm forwarding this message as it accidently ended up with Carolyn
Phelan (CP) in Hewlett-Packard, Bristol England.

Another reminder for the UK folks: Please do no auto-reply to CP
messages. There is a bug in the HP network that causes these messages
to get sent to Carolyn. Please use the '' address.

Thanks! - Rick

... and to David: I've got a paper kicking around at home that gives
the protocol for Pinguicula. It's basically a soak in several reagants,
a stain, a squeeze between microscope slides, and a look with a 1000x
optical microscope. I'll try to dig it up and bring it in.

Also note that many species have chromosome information in the CP database
(courtesy Jan Schlauer). You might want to focus on species that have not
yet had their chromosome counts already determined.

I'm assuming that "extracting DNA" means counting chromosomes? - are
you after a test-tube of DNA jelly?
