The hybridation is possible from all the orchids of the same specie?

Interesting.
Cattleya Alliance Species and Hybrids
From now on i would like put more attention at the note about the parents of Hybrids.

Where i can find information about hybridation?
For example here said that the Brassavola nodosa transmits it to his descendants:

the compact size of the plant
the size of the flowers
the ability to bloom several times a year
the long-term flowers
the curious aspect of the leaves
and also the smell at night.
