XXXI. DETERMINATIONS OF PLANTS COL- 

 LECTED BY DR. J. H. SANDBERG, IN 

 NORTHERN MINNESOTA, 

 DURING 1891. 



J. M. HOLZINGER. 



[The plants listed below were collected by Dr. J. H. Sandberg, under 

 commission from the U. S. Dept. of Agriculture. The determination of 

 them was carried on by Mr. J. M. Holzinger while assistant botanist in 

 the National Herbarium. Dr. George Vasey, at that time Chief of the 

 Division of Botany at Washington, expressed a willingness to have the 

 report printed by the Minnesota Survey, and Mr. F. V. Coville, present 

 Chief of the Division of Botany, has ratified the wish of Dr. Vasey by 

 turning the MS. over to Mr. Holzinger for publication in Minnesota 

 Botanical Studies. The collections here listed were made over that 

 part of the state extending between the western end of Lake Superior 

 and the lake Itasca region, covering the southern portions of the counties 

 of Lake, St. Louis and Itasca, and portions of the counties of Carlton, 

 Aitkin, Cass, Crow Wing and Morrison. Smaller collections made in the 

 counties of Hennepin, Ramsey, Goodhue and Chisago are also included. 

 The list as a whole is highly valuable as giving a good idea of the plant 

 population established around the head waters of the Mississippi. By the 

 purchase during the present year of Dr. J. H. Sandberg's entire collection 

 the duplicates of most of the plants listed here have been added to the 

 Minnesota collections of the Survey. The rest are on file in the cases of 

 the National Herbarium.— .Editor.]
