PLANTS OF SOUTHEASTERN ALASKA. 



J. P. ANDERSON. 



The following list of species is based on collection and observa- 

 tions by the writer except in the case of a few grasses and 

 sedges from Sitka of which specimens are in the herbarium of 

 the U. S. Agricnltural Experiment Station at that place. 



Proper facilities for the determination of all the species not 

 being- at hand, setsi were sent away for determination. The Sitka 

 collections were sent to the U. S. National Herbarium while the 

 plants from Juneau were sent to the New Yorlc Botanical Garden 

 where they were determined by Dr. P. A. Rydberg. 



In regard to the localities mentioned the following notes may 

 prove helpful. 



Sitka is situated on the west or seaw^ard side of Baranoff 

 island in latitude 75° 3' N. and longitude 135° 20' "W. The 

 winters are mild and wdth but little snow. The summers are 

 cold. Numerous small islands abound. Large bogs occur near 

 the town. 



Sanitarium, generally known as Sitka Hot Springs, is located 

 16 miles south of Sitka on Baranoff island. It is a health re- 

 sort. Here are several hot springs of mineral water. 



Juneau is located on the mainland in latitude 58° 18' N. and 

 longitude 134° 24' W. The winters are several degrees colder 

 than at Sitka and generallj^ with considerable snow. The sum- 

 mers are slightly warmer. 



Mendenhall is a small settlement about 11 miles northwest of 

 Juneau. As used in this list it comprises a glacial plain about 

 five miles long extending from the sea to the present foot of 

 Mendenhall glacier. The flora here differs somewhat from 

 that of the surrounding country and some strictly alpine plants 

 occur. 



One trip was made up the Taku river in Septemiber, 1917. 

 The collections were made about three miles from the mouth of 

 the stream.
