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.
