After reading the interesting discussion on hybrids I like to add the
following : 
There are two different definitions for hybrids:

 1. The geneticist definition: A hybrid is a cross between two organisms
differing in one or more characters.
2.The taxonomist definition: A hybrid is a cross between two different

Questions: One ( of the many ) problems with hybrids in the wild is
timing. Most of our plants are of hybrid origin. The question is: how
old must the hybrid be to be given species status?  100 years- a million
Would hybrids be recognized as such as the parents no longer exist?
