SUPPLEMENT TO THE FLORA OF MINNESOTA. 



By Wasben Upham. 



The following notes, chiefly received from the botanists named 

 on pages 10 and 181 of my Flora of Minnesota, show the accessions 

 to the known flora of this state, and to knowledge of the geo- 

 graphic range of species, since the publication of that report 

 two years ago, without, however, including the plants collected 

 at Vermilion lake and vicinity by the botanical party of the 

 State Survey, during the season of 1886. Twenty-two localities 

 are added on the authority of Mr. L. R. Moyer and sister, of 

 Montevideo, who have furnished a catalogue of species growing 

 in Chippewa county. 



Descri ptions of the plants added are found either in Gray's 

 Manual or in Coulter's Manual of Rocky Mountain Botany, except- 

 ing three, of which descriptions are here given.

Accessions. 



Anemone nudicaulis, Gray. "I wish to direct the attention of any of our 

 own botanists, who ma* next summer be visiting lake Superior, to a singular 

 Anemone which grows in bogs and on banks near the water at Sand bay, 

 Minnesota, very near lat. 48°, and in or near the Canadian boundary. All I 

 know of it is from a specimen sent to me in a letter, dated August 8, 1870, 

 from Mr. Joseph C. Jones, then of the U. S. Steamer Search. He wrote 

 that the plant was found growing in mossy ground, close to the water's 

 edge, and also in bogs, and that it grows in the manner of Coptis tri folia. 

 I believe it has filiform rootstocks, like those of Anemone Richardsoni, and 

 the radical leaves are so like those of that species thst I inadvertently mis- 

 took the plant for that species. But the involucre consists of a single peti- 

 olate leaf, very like the radical, or else is wholly wanting. And the akenes 

 are tipped with rather short and hooked styles, very unlike the long ones 

 of the aforesaid Arctic species. A flowering specimen is a desideratum." — 

 Am Gray in Botanical Gazette, xi, 17, Jan., 1886.
