Hi,
Just to be precise (excerpt from Small Lot Seed Permit):
7. Each packet must be limited to a maximum of 50 seeds of 1 taxon (taxonomic category such as genus, species, cultivar, etc.) per packet; or a maximum weight not to exceed 10 grams of seed of 1 taxon, per packet.
8. Each shipment must contain no more than 50 seed packets.
