Intergenetic/hybridization compatibility

[Uechi]

It is my understanding that all orchid species are not capable of being hybridized with every other orchid species. There are only certain species that can hybridize with Cattleyas for example. What I am trying to find out is if a book/s or written list exists that tells you what orchids can be crossed with what orchids?

I would say that most of orchid hybridization is by trial and error. The Sander's List/RHS registery should give you an ideal of which orchids easily hybridize with others by looking at their Grex or Parentage. Understanding Orchids by William cullina has a table of hybrid genera. Hope this info helps some.

and if you want to saty on the safe side, use only plant within the same tribe...

I have been curious about this too. What if you cross an Iwanagara with a Potinara?
