Help Identifying Seeds

Hi Guys,
Was wondering if any old schoolers were out there that could possibly help me. I ordered seeds way back from dr chronic and gypsy nirvana, this was back in 2007. I recieved some freebies that no one can identify. It just says N.S. x Millen ?!?! Any ideas? Any help would be greatly appreciated.

"N.S. x Millen" = "Niagara / Shiva x millennium" if my memory serves me, if not any other ideas?
