CATALOaUE OF TREES AND SHRUBS. 
In the following catalogue we have omitted the localities given 
by Fitzpatrick, Shimek and Macbride. They are not generally 
recorded in this list because the localities appear in a separate 
table. 
We have generally used the initials of the collectors as fol- 
lows : LHP — L. H. Pammel, Rose Schuster Taylor — RST, 
HBC— H. B. Clark, LHP and HBC— L. H. Pammel and H. B. 
Clark. 
The species listed are generally represented by specimens. We 
are indebted to Professor C. S. Sargent for verification of some 
species and to Mr. C. R. Ball for the verification of some of the 
willows.
