Hi Adam and all,

Adam, I hate to burst your bubble, but Pancratium and Hymenocallis are not 
particularly closely related.

Hymenocallis is in the American Clade of Amaryllidaceae, related more 
closely to Hippeastrum, Ismene, and Griffinia than to Pancratium.

Pancratium is in the Eurasian Clade, most closely related (by DNA) to 
Sternbergia and more closely related to Narcissus, Lycoris, and  Galanthus 
than to any American amaryllid.

Be prepared to use in vitro embryo rescue to grow any seeds resulting from 
crossing Hymenocallis and Pancratium.  Or at least don't say I didn't warn you!

Best regards,
Jim Shields
