 Comments
       
  Comment: Stoermer, E. G., R. G. Kreis, Jr. and N. A. Andresen in J. Great Lakes Res. 25(3):515-566: Melosira crenulata (Ehrenb.) Kütz. and Melosira crenulata var. tenuis Kütz. present problems of interpretation. These are old names which by contemporary standards were dumping grounds for Melosira specimens. Records at the Academy of Natural Science of Phildelphia Diatom Herbarium demonstrate the problem. Each of the Academy's records have samples associated with them so that verification can be made. Among the many records for Melosira crenulata there are seven different Melosira taxa listed in synonomy for various collections. Until we are able to examine the Great Lakes collections on which the M. crenulata records were based it would be most prudent to leave the names as they stand without attempts to suggest synonyms.
