I do not know if a fertile cross has been tried, and I don't know the karyotype, but I suspect that it might be possible.
Plant and animal genetics are different, and so the species concept in animals may or may not apply. I will agree that if any 2 species can form fertile hybrids, then this issue has to be looked at very carefully before assigning species rank.
In Drosera, these type of plants form "complexes" and they are complex! This is where taxonomists "duke it out" and where molecular genetic analysis becomes useful to determine where in the phylogenic tree a given example is placed. Its all very interesting (and often confusing). All members of the various complexes (e.g. aliciae/natalensis, petiolaris, capillaris, peltata/auriculata) must be investigated, and field studies done before publishing a species. It's a lot of work!
I suppose we would all like the plants to behave in the same way that animals do, that would make life a lot easier!
Goldtrap,
The Lobsters and Crabs I will deal with (into the pot they go, ahhh, with some melted butter! I'll eat them before they eat me) but the scorpions are OUT. They are my greatest phobia.
(next to air flight that is!)
(and s-s-s-snakes!)
