state. It is following a policy of public education already in 

 force in neighboring states, many of which have tree bulletins. 

 Trees play a large part in the economic and recreational life of 

 the state and a better understanding and appreciation of them 

 is bound to lead to ultimate good. In the treatment of the sub- 

 ject in hand it has seemed wise to include in these pages not only 

 those trees which are conceded to be native to the state but also 

 those which have become naturalized within our boundaries and 

 propagate themselves in the wild condition. Listed among these 

 are such foreign trees as the White Willow, the European Crack 

 Willow, Paulownia, etc., or trees introduced from other parts of 

 the United States, as Osage Orange and the Catalpas. Orna- 

 mental trees which are never found as "escapes" are omitted 

 as are those species such as Witch Hazel or Cordate Willow w^hich 

 are shrubby within the state but arborescent elsewhere. In some 

 cases the author has been in doubt as to just where to draw the 

 Ijne. The treatment throughout must be considered conservative. 



There are within the borders of the state one hundred and 

 thirtj^-three kinds of trees exclusive of Crataegus. Of these one 

 hundred and nine may be considered as native and twenty-four 

 as naturalized. Over two hundred species of Crataegus have 

 been described for New York State alone but these exhibit such 

 a multitude of bewildering forms as to be beyond the scope of 

 the bulletin. The inclusion of Crataegus brings the total num- 

 ber of native arborescent species well over three hundred and 

 ranks New York State as one of the richest in the Union in its 

 arborescent flora. No attempt has been made to include the 

 shrubby plants of the state in this publication. 



The descriptions accompanying the plates are based in part on 

 fresh and herbariiun material available at the College of For- 

 estry or in the herbarium of the Department of Botany, Syracuse 

 University, in part from descriptions checked with living mate- 

 rial from Sargent's Silva, Britton's North American Trees, 

 Hough's Handbook of the Trees of the Northeastern States and 

 Canada, Gray's Manual, and Bailey's Cyclopaedia of Horticul- 

 ture. I am especially indebted to Prof. W. C. Coker of the 

 University of North Carolina, to Prof. J. S. Illick, of the Penn- 

 sylvania State Forest Academy, to Mr. Henry Hicks of West- 

 bury, Long Island, and to Mr. C. Leo Macy of Princeton, New 

 Jersey, for assistance in collecting specimens of trees which grow 

 along the southern border of the state.
