    Drosera tokaiensis x rotundifolia?

    I purchased a plant labeled as such and was wondering if that's possible. I understand the origins of D. tokaiensis as spatulata x rotundifolia but I also read they are self fertile. Is it possible then to back cross with a rotundifolia? Or was the plant just labeled incorrectly? I seem to forget how different sundews cross with each and such, so forgive me for a rather simple question...genetics was never my strong point.

    Fertile D. tokaiensis is a hexaploid (2n=60). It should be possible to hybridize it with the diploid D. rotundifolia (2n=20). This should result in tetraploid D. ×tokaiensis (2n=40) which may or may not be fertile. Double that with Colchine and cross the octoploid (2n=80) with a tetraploid D. spatulata (2n=40) should result again in a hexaploid D. ×tokaiensis!

    See this paper by Ivan Snyder to figure out how this works:

    Note the biohazards of Colchicine
