    Intergeneric Sarraceniaceae Hybrids?

    Has anyone ever attempted to cross the different genera within this family? Like Sarracenia Heliamphora, Darlingtonia Sarracenia, etc.? I've always wondered if something like D. californica S. psittacina would be possible since they resemble each other so much, but it actually turns out they are only distantly related within the family according to the DNA cladogram on this page. Rather it looks like Heliamphora is a sister taxon to Sarracenia, so those two would probably be the best candidates. Such a combination would produce some crazy plants for sure.

    I dont think it would work but it would be an interesting thing to try...


    In addition to growing plants, I design and build RC planes powered by Tesla batteries. Check out my progress at www.chargedplanes.com

    Not going to happen:

    Chromosome counts are incompatible:

    Darlingtonia (2n=30)
    Sarracenia (2n=26)
    Heliamphora (2n=116) * H. heterodoxa and H. nutans

    After meiosis the gametes would contain (n=) 15, 13 and 58 respectively. None are the same or multiples of the n count.

    True, though a horse (2n=64) and a donkey (2n=62) can still breed together and produce offspring with 63 chromosomes. It doesn't seem too far-fetched that Darlingtonia and Sarracenia might be able to produce offspring with 28 chromosomes, especially considering that plants are tolerant of chromosomal aberrancies than animals are.

    Well, if my plants ever come into flower at the same time, I'll have to give it a try! A Dionaea Drosera cross would be sweet, though their trapping mechanisms are so different it seems that IF they were to cross successfully, the resulting plant would end up with defective snap traps and cilia and not be able to catch any prey. Who knows...

    Horses and Donkeys are in the same genus Equus, species Equus caballus and Equus asinus, respectively. There's enough genetic similarity that the chromosomes can form homologous pairs and fertilization occurs. The resulting offspring is viable in the same manner as an aneuploid (2n+1 or 2n-1).

    Between genera is a different matter.

    Crossing Dionaea with Drosera

    Dionaea (2n=30 or 32)
    Drosera (2n=12,14,18,20,22,26,28,30,32,34,38,40,46,60,64, or 80)

    The most genetically similar Drosera species to Dionaea (based on chloroplast rbcL and nuclear 18S ribosomal DNA) is Drosera regia (2n=34). The similarities are not enough that you'll get fertilization.

    You aren't the first to have thought of this and tried it. You won't be the last.
