    FOr your interest, here are some ploidy counts for other members of the genus. Matching karyotypes are all possible candidates for hybridization. Thanks to the CP Listserve for this data, used completely without permission because stealing and sharing data is a learning experience!

    Drosera ploidy counts

    Subgen.Thelocalyx - D.burmanni (20)
    Subgen.Stelogyne - D.hamiltonii (28)

    Oh no, you can't get me going on genetics, not one of my strong points. You need Dr. Frankensnyder, errrr....Ivan Snyder. Google Ploidy Ivan Snyder, read and learn! Almost anything I say is as likely to be wrong as it is right;-)
