LIST OF, AND NOTES UPON. THE LICHENS COLLECTED BY 



DR. T. H. BEAN IN ALASKA AND THE ADJACENT REGIOI7 IN 



1880. 



By Dr. J. T. BOTUBOCK.' 



Many ne^ species of lichens from a boreal region were hardly to be 

 expected, inasmuch as the similarity of the northern flora is great in all 

 longitudes. It is not surprising, however, that we do find in this col- 

 lection quite a number of interesting forms, which illustrate the laws of 

 variation inside specific limits in connection with geographical distribu- 

 tion. One new Biatora. however, from Eastern Siberia, rewarded Dr. 

 Bean's active search. 



For whatever accuracy in names this list may have I am indebted to 

 my friend Mr. Henry Wniey, who has kindly gone over the collection. 



It wiU be observed that there are no notes given in this list (save of 

 locality, &.c.) until the genus BcEomyces is reached. This is because 

 the recent publication of Professor Tuckerman's invaluable "Xorth 

 American Lichens" includes all the species before this genus, and hence 

 renders anything more unnecessary. 



Considering how inconspicuous the lichens usually are. and also how 

 varied Dr. Bean's duties were, it is a matter of surprise that he has 

 been able to obtain so satisfactory a collection.

* It is due to Mr. Willey to say that it T%-as his desire to correct the proof. This, 

 however, has been prevented by want of time in the printing. It ia hoped that no 

 errors of importance will be found. — J. T. E.
