Without breeding the plant or chromosomal identification,there is no way to be sure. H. Striatum looks very similar. If it is Striatum, The babies dont grow from the mother bulb,but from underground runners as much as a foot away from the mother bulb.

Thanks Del for the link and the info. You are so helpful :-)

The blooms and the scape show similar characteristics to the the third picture of your first link ... so I think I will, for the time being, tag mine as Hippeastrum Puniceum :-)
