The Apples of New York. 



the calyx tube where the stamens are inserted, though sometimes appar- 

 ently below the insertion of the stamens. See plates of Ribston and 

 Sharpe. The iibrovascular bundles which niaj^ be most easily followed 

 in tracing the core lines are normally ten in number, as shown in Figs. 

 8 and 9. They occur one opposite each outer angle and alternately one 

 opposite each inner angle of the seed cells. Consequently a longitudinal 

 section through either the outer or the inner angle of a seed cell brings 

 out the core line most clearly. 



Clasping core lines is a term which indicates that the core lines appear to 

 join the calyx tube along the side somewhat above the base of tbe tube, 

 as shown in the plates of Admirable, Ribston and Green Sweet.

Core lines meeting is the term used when the core lines appear to join the 

 calyx tube at or near its base, as seen in the plates of Bullock and York 

 Imperial. 



The point at which the core lines meet the calj^x tube does not vary 

 materially in the same variety although different descriptions of it may vary 

 when in the same variety some of the apples show a funnel-form extension 

 of the calyx tube towards the core and others do not, as stated below in 

 discussing the calyx tube. 



In some cases before the fibrovascular bundle reaches the caly.x tube 

 it sends ofif a distinct branch to the calyx lobes as seen in the plates of 

 Fallawater, Green Sweet and Newman. 



Calyx tube. The hollow just under the calyx lobes is called the calyx 

 tube, Fig. 3, d. This may be cone-shaped, as in Dickinson and Salome, or 

 when it is extended below in a nearly cylindrical narrow tube it is funnel- 

 form, as in English Russet. If instead of assuming either of these forms
