It is uncertain what specific name this Cyperus should bear, and until all the species 

 have been properly defined and their synonymy reduced, many of the names in use can 

 only be regarded as provisional. The Bermudan species has been referred to Cyperus 

 phymatodes, Muhl., to Cyperus esculentus, Linn., and to Cyperus flexuosus, Vahl.
