I think I see two stigmas per flower/fruit which would make this Sparganium eurycarpum.

    You're welcome! Range maps don't show this species as occurring in Georgia but I haven't checked any Georgia databases to see how off they might be. Posted 5 years ago

      Oh, now that I'm looking, I'm not so sure:
      You can see the most current range map on Weakley's key here (I did a CTRL-F for "Sparganium" once it loaded):

The Broadfruit Bur-reed, Giant Bur-reed

'Sparganium eurycarpum' is a species of bur-reed known by the common names broadfruit bur-reed and giant bur-reed. It is native to wetlands in Eurasia and North America. It is a clonal perennial, spreading by below-ground rhizomes. The common name, bur-reed, arises from the distinctive round clusters of fruits that take the form of a mace. It can be distinguished from all other species of bur-reed by the presence of two stigmas.
