SUPPLEMENTAL LIST OF PLANTS FROM SOUTHEAST- 

 ERN ALASKA 



J. P. ANDERSON 



The following list comprises plants that have been collected or 

 determined during the past year. The larger portion of the species 

 here enumerated is the result of a trip to Haines and Skagway at 

 the head of Lynn canal on August 19 to 21, 1918. Elevaticns are 

 only approximate. The writer was told by well-informed resi- 

 dents of Skagway that the elevation of upper Lake Dewey was 

 about 4,000 feet. All species for which this elevation is given were 

 collected in the vicinity of the lake. 



Most of the determinations were made by Dr. P. A. Rydberg, of 

 the New York Botanical Garden. 



In addition to the list here given there is a small amount of unde- 

 termined material and what appears to be undescribed species of 

 the following genera : Alsine, Epilobium, Solidago, Aster, Arnica.
