TEHON: FIELDBOOK OF NATIVE ILLINOIS SHRUBS 13 



other page, knowledge of the shrubs that grow in Illinois is by 

 no means perfect. The catalog of species occurring in the state 

 undoubtedly is very nearly complete, but too little is known of 

 the exact distribution of individual species. To one interested in 

 shrubs, a survey of the township or county in which he resides 

 and the making of a local collection for the region in which he 

 lives will yield results of real scientific value, especially if pub- 

 lication of a species list and habitat notes can be achieved.
