I always though crosses were limited to the same alliance, though Ramon says it's within the same tribe. Alliance= highly related genera within a single tribe, that usually can be crossed

So for instance, I consider crosses between Phals and Vandaceous plants to be an exception, while by Ramon's definition it's normal.

Actually, crossing within the same alliance is an almost 100% success warranty (not always, tough!). These genera are always very closely related and therefore you have less genetic incompatibility.... Crossing within the same Subtribe gives also a high percentage of success, but less than wihin the same alliance... Within the same tribe, the rate of success is reduced once again... The difficult (impossible in many cases) is when you try to cross between tribes
