" Probably there exists no other region in the State of more interest to the student 

 of ecology than this valley of the Upper Susquehanna, for it affords some striking 

 instances of northward extension in several typical southern species. It is this cir- 

 cumstance which lends a peculiar interest to all local floras whose areas fall near the 

 boundary line between two distinct life zones investing them with more than a mere 

 local value. It is pleasing to note that the nomenclature of this volume follows modern 

 lines, the equivalent of the names of Gray's Manual being cited in parenthesis for the 

 sake of convenience. ... In the introduction is given a comparison with related 

 floras, a full discussion of the geology and geography of the area and a most interesting 

 list of noteworthy sub localities." — C. L. Pollard in The Plant World. 



"In many respects it is the best we have seen; for it tells in a few brief words 

 all that is needed by a collector to know, leaving the full description to the larger 

 works which all advanced students possess. Indeed, it tells more by adding points of 

 general history. These notes are so valuable that others besides those collecting in 

 the Upper Susquehanna will find it a little book profitable to have on hand."
