I've read about apomictic tendencies with L pumilum and it appears true as my pod appears fertilized with none going on. Rick also mentioned it with martagon seed. What species and or situations could produce apomictic seed?

Lilium regale is renowned for it, but I have no personal experience.

At the NALS convention, Darm Crook told me that he has found that both Lilium michiganense and L. canadense can produce seed apomicticly. Moreover, he thinks that even if a flower is cross pollinated (within the species), these species will still produce a small percentage of apomictic seed. Darm has actually scientifically tested these species. Fyi, for other species that are known to be self-fertile, do we really know if they are self-fertile or rather, apomictic?

Good points Rick! I knew you'd come back with your thinking cap on. The other interesting question is, does the application of pollen on the stigma on "self-fertile" species cause a trigger to make apomictic seed as opposed to an unpollinated bloom?

Don't know about that, but what about its corollary:
---- does the application of pollen on the stigma on "self-infertile" species cause a trigger to make apomictic seed as opposed to an unpollinated bloom?

I may be getting close to an answer to that:
Since I only have one blooming clone of L. leichtlinii, I seldom get seed set, but occasionally my L. leichtlinii will produce normal pods, and I've always assumed cross pollination with some other asiatic. (I have purposely produced interspecific hybrids before.) In 2014, I did two protected self pollination tests on L. leichtlinii. One did not yield a pod at all, as expected. The other did, a small pod (but normally shaped) that contained mostly chaff. However, three seeds were found. Unfortunately, I then "proceeded" to lose them until their rediscovery this winter. They had been sitting at room temperature for more than a year, and have just come out of their 2 week freeze period, ready for their planting (today). I hope they make it, and I should be able to verify that they are not hybrids early on before flowering.
Whether they are apomictic seed or selfed is still up for grabs, but this might suggest that self pollination may help to induce seed production of some sort. Now I will need to do more testing....
