APPLE VARIATION 



163 



Polycarpy in the Apple. Grimes' apple having six carpels. Slightly reduced. 



The first, a specimen of the Ben Davis, consisted of two nearly inde- 

 pendent apples united for only a short distance near the base. The 

 stem, originally single, had been split nearly to the base, while that 

 part of the fruit between the insertion of the stem and the point of 

 union of the apples had been broken apart as the apples had developed 

 at the base. The two portions, thus almost completely separated, had 

 each developed into a nearly perfect apple, though of small size. The 

 cores were perfect and the axes, which were nearly straight, extended in 

 almost opposite directions. 



The second specimen, a Jonathan, consisted of two apples of unequal 

 size joined together throughout their entire length and marked off from 

 each other only by a shallow groove. The single stem upon which the 

 fruit was borne was split for a short distance as the two portions spread 

 apart in growing. When cut open each section was found to have an 

 independent core containing perfect seeds, although in the smaller part 

 that portion of the core adjacent to the other part was undeveloped. 

 The axes of the cores, moreover, were strongly curved away from each 

 other. The specimen from Wenatchee was similar in all important 

 respects to the one just described and further account of it will not be 

 necessary. Both of the double apples grown at Pullman are shown whole 

 and in section in the accompanying illustrations. 



Double apples of this kind originate in a manner quite different 

 from the double plums mentioned above. The presence on the mature 

 apple of two separate calyx cups indicates that these apples were pro- 

 duced by distinct blossoms borne at the end of a single flower stalk. In
