Holzinger: mosses of Minnesota. 281 



Dr. J. H. Sandberg and Mr. F. F. Wood collected in 1891, in 

 Northern Minnesota, for the National Herbarium, where most 

 of the material is deposited. Mr. Wood's mosses were deter- 

 mined by Mrs. Britton. Later the collector sent a little of 

 those species which the writer found he had not yet on his list. 

 And only these are embodied in this report. 



Bulletin No. 3 of the Geological and Natural History Survey of 

 Minnesota, pp. 25-26, 1887, reports a list of 33 species of 

 mosses from Minnesota. Five of these are embodied in the 

 present report, not having been found by the author. Refer- 

 ence to localities of the other species is omitted. 



It will be considered a favor if all who are interested in the 

 Minnesota Natural History Survey, and especially those who 

 collect and study mosses, will submit to the writer material 

 from different parts of the state. All such material will become 

 the property of the University Herbarium, and will be fully 

 recognized in the final report.
