Rosendahl and Butters: reputed Minnesota plants 467 



' Sagittaria subulata (L.) Buchenau. 



Reported in Lapham's Catalogue, but does not occur. 

 Echinodprus tcncllus (Aiartius) Buchenau. 



Reported in Upham's Catalogue but does not occur. The report is 



probably based on some small specimen of Sagittaria. 

 Leptoloma cognatum (Schultes) Chase. 



Reported in Upham's Catalogue ; no specimens; occurrence very 



doubtful. 



Panicuni agrostoides Spreng. 



Reported in Upham's Catalogue ; no specimens. 

 Panicuni depauperatum Muhl. 



Various reports, but does not appear to occur ; reports based on 



wrong determination of P. perlonguni Nash, and P. lincarifolium 



Scribn. 



Panicum IVerneri Scribn. 



Reported in Wheeler's Catalog, but does not occur; report based on 

 incorrect determinations. 



Panicum dichotomuvi L. 



Several reports, but does not occur ; reports based on wrong de- 

 terminations of other species. 



Panicum implicatum Scribn. 



Reported in Wheeler's -Catalog; apparently confused with P. villosis- 

 simum Nash. 



Panicum clandestinum L. 



Assumed in Upham's Catalogue to occur ; no specimens. 



Panicum Boscii Poir. 



Reported from Minnesota but all specimens originally so labelled are 

 placed by Hitchcock and Chase in P. latifolimn L. Several speci- 

 »nens, however, show the pubescence character of P. Boscii as given 

 in recent descriptions, but most of the Minnesota plants have small 

 spikelets and in this respect agree with P. latifolimn. The two 

 species do not appear to be sufficiently distinct. 



Echiuochloa W alter i (Pursh) Nash. 



Doubtful whether it occurs ; specimens in the University collection 

 so determined are E. Crusgalli (L.) Beauv. 



Setaria verticillata (L.) Beauv. 



Reported in Upham's Catalogue ; no specimens; it probably does not 

 occur. 



Antho.vanthum odoratum L. 



Reported in Wheeler's Catalog. The report is based on incorrect 

 determination of a single specimen of A. Puellii Lecoq. & Lamotte. 



Stipa canadensis Poir. 



Reported in Upham's Catalogue ; no specimens ; probably does not 

 occur.
