Right now, in the Mexican Ping department, I have the following
species + hybrids flowering....

P.X sethos
(and very soon) P.emarginata

Anyone have chromosome info for these, so I know if there's any point
to trying hybridization?
I do not have, nor do I care to mess with, colchicine (sp?) or other
such N-doubling agents.
