In the following pages the scientific name is printed 

 in parenthesis, in italics, under the common name. It is 

 hoped that those who really wish to know our trees by 

 the names now accepted for them everywhere will famili- 

 arize themselves with these names in particular. 



THE TREES OF THE STATE.* 



TREE DEFINED. 



Woody plants which continue to grow for some years 

 are known either as shrubs or trees. Size is usually made 

 the line of separation between the two but the form of 

 growth is quite as characteristic. The following quoted 

 definition seems to express the commonly accepted idea 

 of a tree: "Trees are such woody plants as produce in 

 nature a single trunk, branching more or less above the 

 ground. "t Accepting this definition, there are included 

 in the following list a few that are comparatively small, 

 such as the Buffalo Berry and the Choke Cherry. But 

 even these have the true tree habit and may properly be 

 included. 



^Special attention is called to Bulletin No. 38 by Prof. B. C. 

 Buffum, recently issued by this Station. That bulletin bears the 

 title " The Cultivated Shade and Forest Trees," and considers in 

 detail the characteristics and relative value of the various trees 

 that are used on home and public grounds. Methods of trans- 

 planting and cultivating are also considered. 



Since native trees must be so largely used for decorative 

 purposes both on the home and public grounds it seems probable 

 that a bulletin on how to recognize them may be welcome. For 

 this reason this bulletin is made to follow so closely, in order 

 that the two may supplement each other.
