Ismene seedling -- is this the ture narcissiflora?

Until Alan Meerow comments, I'll hazard some guesses.

I agree that the Ismene (Hymenocallis no longer includes Ismene) shown is 

Lots of amaryllid genera produce fleshy seeds, while most of the rest 
produce flat, dry, papery seeds.  There are a few apparent exceptions.  The 
fleshy seeds in Crinum, Brunsvigia, Nerine, Hymenocallis, Clivia, 
Haemanthus, Scadoxus, and probably some more genera  that have slipped my 
mind, are true seeds most of the time.  Self-pollination in Crinum tends to 
produce huge lumpy seeds while pollination from a different individual 
often produces much smaller, round seeds.

However, I don't know what the Ismene x-Festalis flowers are producing!  I 
always thought that they were completely sterile.  Since this is obviously 
not the case, they could be either apomictic or true (sexual) seeds.  Let 
us know what the offspring's flowers look like when they eventually bloom,
