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?
