Epi (Radicans?) cutting in spike

[Beginning-lie]

Not really at all familiar with these. This was a pair of cuttings I received around November, poked them into bark, and they seem happy enough. I'm given to understand this cane won't bloom again, but should set new canes and/or keikis. The parent plant was growing terrestrial and froze December. What insects pollen are these? Just wondering if I could get some seed to volunteer, as I understand that they are wont to do.
