Among many items of interest encountered during the past year in routine work in the Herbarium of the State University of Iowa, the following seem worthy of record. The discovery, in Muscatine County, of n fine colony of Glyceria in the fluitans complex, led to a review of this section of the genus. All of our specimens collected over the past half century had been filed as G. fluitans. The differences between this species and G. septentrionalis Hitchc. seem rather slight yet if we follow actual measurements we must refer all of our eastern Iowa specimens to the latter species, as Conard has done. Two specimens of Cratty's, from Emmett County seem to be the closely related, but more distinct, G. borealis (Nash) Bachelder.
