Mini catts Looking for infos

[Intruder]

Dear All;
At the time of our Orchidays exibition in May 2008, I will wish to do a presentation on the mini-cattleyas, those which one cultivates on the windowsills. I thus seek informations on the selection criteria of the parents used by the hybriders to create those. Any remarks or references on this subject will be very apprecied. Many thanks in advance.
