Well, I'm super happy to report that I've got two potential sources of pollen now: some spathulata x spectabilis from a user on here that is ready and waiting (yay!) and I also nabbed a cheap spathulata x petiolata male in spike. It seems to have kept it's flower through shipping so hopefully it will be a good backup just in case the first batch was damaged in the mail.
A cursory google search doesn't show any results for either of those grexes, and it would be neat to see the results. I have some N. robycantleyi and some mixed hybrid seeds in microprop right now for my first test batch, so if it is successful some of this seed will go straight into agar also. Our sterile process is confirmned successful, and I am just waiting to see if I've murdered the seeds along the way or not. Such a wait involved with these silly things.
