Mrs. Peterson's How to Know Wild Fruits 



A GUIDE TO PLANTS WHEN NOT IN FLOWER BY FRUIT ANDJLEAF. 



By MAUDE G. PETERSON. 



IT is a comparatively easy matter to identify 

 with the help of modern field books any 

 unfamiliar wild flower, but there is an utter lack 

 of similiar reference books serviceable to those 

 whose drives and walks are taken when it is no 

 longer the brilliance of flowers that demand the 

 attention but the attractive coloring and contour 

 of the masses of fruits. Analysis can not be of 

 any avail and in existing botanies the descrip- 

 tions of fruits are tantalizingly meagre. This 

 guide based on the kind and structure of the 

 fruit will aid in determining the family to which 

 a plant belongs and under each family the 

 species are grouped by colors. 



Fully illustrated, cloth ISmo, fl.50 net (postage 13c. ).
