    Seriously, I think if it were physically possible to hybridize our SE USA pings with Mexican pings, it would have been done already. I think the genetics prevent it.

    That's another "can of worms"! Why are supposedly separate and distinct species within a genus able to be crossed and produce viable offspring?

    2n is the chromosome count. n is the number of chromosome pairs. In humans 2n=46. When the cells divide through meiosis to form sex cells (ova and sperm) the 2n count is halved (13 in humans). When fertilization occurs the chromosomes again become pairs with a 2n=46.

    Hybridization is more likely to occur if the 2n counts are equal. Fertilization will only occur if there is enough genetic similarity between the species.

    Intergenic hybridization (between different genus) is even less likely due to even less genetic similarity.

    See this article for more information. Although the subject are Drosera the same principles apply:

    Because two species being able to breed with one another successfully is not what determines them also being within the same genus. Really, the concept of Nepenthes gets us (well me anyway) spoiled because they so readily hybridize with one another. There are many Drosera and Pinguicula that cannot hybridize together, a lot of that has to do with the fact that members of those two genus are very widespread. Whereas Sarracenia and Nepenthes are native to basically one distinct region, Drosera and Pinguicula are found throughout the world and in their own separate regions have had a long time to evolve independently of one another. There's no reason to put them in a separate genus, though.

    what about subgenus are there any ping subgenra (subgenuses?)

    So much for Ontogeny recapitulating Phylogeny!
