a single blossom or a cluster; there will be no rigorous 
adherence to an exact classification; no attempt made to 
distinguish between fruits formed from a simple pistil 
and those from a compound one; nor generally between 
those formed from a single and those formed from a clus- 
ter of flowers. The fruit and its general classification, 
determined by the parts easily seen, is all that will be 
attempted. 
As stated before, it is hoped that this volume will not

objects, but that the amount of information here given 
will lead to the desire for much more.

The dry drupe is like the Cherry drupe except that the 
flesh is much harder. The fruit of the Walnut, Hickory, 
and Sumac. 
The inner hard-coated parts of

part of the fruit has a regular 
place for splitting open, it is de-
