You are correct...exact species I don't know. The curling is ok...it's the plant type habit.
If you leave the flowers they will produce good. At least they did for me, I probably had about 20 babies pop up in my tank. I don't know what pollinated them....take a q-tip and rub it over the flowers and share the pollen!!!
Right now this is the only one that's flowering and I'm not even sure if the others I have are the same kind (the bf bought one of those mystery bulb packs) so who knows if I can even get results pollinating them. Or can I pollinate it with flowers from the same plant? *clueless*
The flowers can pollinate themselves, you can rub each flower with a q tip as suggested just to stir up the pollen on each of the little flowers, you shouldnt have to worry about cross pollinating or anything. I believe that is the flower of a hybrid aponogeton, I have one of those growing my tank that has flowers just like that and the best I could conclude from researching via google was that it is a hybrid.
Yes, it is definitely aponogeton sp. My Aponogeton ulvaceus keeps flowering similarly and I have to cut them. But don't expect them to produce useful seeds for you, at least splitting the mother plant is a quicker way...
