8 TWELFTH ANISTTAL REPOBT. 



vascular cryptogams, of which 289 were collected on the northern 

 border of Minnesota, from the lake of the Woods to the Red river. 

 Twenty-three species of mosses and lichens were also collected on 

 this part of the international boundary. The rushes, sedges and 

 grasses of this list were determined by Prof. John Macoun; by 

 whom, as also by Mr. Dawson, some additional notes respecting 

 their identifications of species and more recent collections in the 

 same region and thence eastward to lake Superior, have been kindly 

 furnished. 



Another collection of plants, numbering about 300 species, was 

 made on the same survey, along its extent from the Red river to 

 the Rocky mountains, in connection with the U. S. Northern 

 Boundary Commission, by Dr. Elliott Coues, who submitted them 

 t) Prof. J. W. Chickering for determination and report. With 

 these were also incorporated the species of Mr. Dawson's list (ex- 

 cepting mosses and lichens), so far as they were not included in 

 Dr. Coues' collection, making a catalogue of 692 species, besides 

 several varieties; which was published in 1878 in the Bulletin of the 

 United States Geological Survey, vol. iv, pages 801 to 830. Ninety- 

 six species are stated to have been found at Pembina, situated on 

 the Red river, adjoining Minnesota. 



A few species of Carex, collected by Sir John Richardson at 

 Rainy lake and the lake of the Woods, and determined by Dr. 

 Pram3is Boott, are included in the botanical appendix of Richard- 

 son's Arctic Expedition in Search of Sir John Franklin; which 

 also gives much valuable information as to the geographic limits 

 northward of many of our plants. 



A list of the ferns of Minnesota, collected by Miss E. W. 

 Cathcart, comprising thirty species and three varieties, was publish- 

 ed in 1877 in the Bulletins of the Minnesota Academy of Natural 

 Sciences^ vol. i, pages 303 and 301. This list includes two especial- 

 ly interesting species, the very rare Phegopteris calcarea. Fee, and 

 Woodsia scopulina, Eaton, which here reaches its eastern limit. 



The Report of the Minnesota Horticultural Society for 1884 con- 

 tains, in pages 83 to 116, a valuable paper by Miss Sara Manning, 

 on "The Wild Flowers of the Lake Pepin Valley", including a 

 catalogue of 501 species. 



In the same report, on pages 361 to 367, are "Notes on the Flora 

 of western Dakota and eastern Montana adjacent to the Northern 

 Pacific railroad," by John B. Leiberg, in which are frequent inci- 

 dental references to Minnesota.
