A new station for Hemlock in Minnesota 



E. I. Roe and P. O. Rudolf 



A new location for eastern hemlock {Tsuga canadensis (L). 

 Carr.) in Minnesota, probably representing the westernmost 

 occurrence of this species in North America, was recently called 

 to the writers' attention by officers^ of the Division of Forestry 

 of the State Conservation Department. The fourth station for 

 this species definitely known to exist within the State at the 

 present time, it consists of a group of three trees (Figures 1 and 

 2) about 400 feet south of State Highway Number 27 (from 

 which they are plainly visible) in the northeast \ of the north- 

 east I of Section 14, Township 43 North, Range 25 West, Mille 

 Lacs County. 



The area was visited by the authors in early November, 1935 

 and the measurements taken which appear in the accompany- 

 ing table. Total height was obtained by means of an Abney
