A SYSTEMATICAL INDEX 



OF THE NAMES OF TREES OF THE EASTERN 



UNITED STATES, 



INCLUDING THE BOTANICAL NAMES ACCORDING TO 



PROF. ASA GRAY AND PROF. C. S. SARGENT 



The letter on the right of each botanical name is the initial 

 of the common name. The botanical name according to Prof. 

 C. S. Sargent is referred to that according to Prof. Asa Gray. 

 The revised names according to the system adopted at the Inter- 

 national Botanical Congress, Vienna, June, 1905, are in the Alpha- 

 betical Supplement. 



All specific geographical names such as Americana, Canaden- 

 sis, Caroliniana, Marylandica, Pennsylvanica, and Virginiana, are 

 now, in accordance with the Vienna Code, written americana, 

 canadensis, caroliniana, etc. This is an important technical 

 change, but it is not one which carries weight in any other 

 direction, consequently on many of the preceding pages the capi- 

 tals remain unaltered.
