As  in  all  the  species  of  Rubus,  cells  with  crystal  clusters  are  com- 
mon, particularly  near  the  base  of  the  style.  Reticulated  cells  occur 
in  the  inner  layers  adjoining  the  endocarp.

wrinkles  the  thickness  of  this  coat  is  exceedingly  variable.    As  in

the  strawberry,  the  sclerenchyma  fibers  are  longitudinally  arranged 
and  cross  those  of  the  inner  endocarp  at  right  angles.  The  fibers 
are  a  little  narrower  than  in  the  latter  fruit,  and  in  cross  sections  are 
usually  elliptical-polygonal,  with  the  longer  diameters  in  radial 
directions.
