_Dr. regia_ has 2n=34, _Di. muscipula_ has usually 2n=32
(there is also an intriguing count of 33 by Hoshi & Kondo!)
chromosomes (cf. cp database).

They definietly are. Besides the morphological similarities, genetic
alignments place _D. regia_ (and not _D. falconeri_ or any other
Lasiocephala; Hi Ivan, I do not buy your theory - but I doubt you
believed I would, anyway!) at the very base of the genus _Drosera_,
quite close to _Dionaea_.

Good luck! The different chromosome counts and the quite different
growth form (incl. the pollen/ovary/style/stigma structure) of the
two will perhaps cause problems but it is definitely worthwhile to
give it a try. BTW, do you have _Aldrovanda_ (2n=48) handy?
Kind regards
