to  4  layers  of  stone  cells  having  thick  walls  that  are  pierced  by 
numerous  pore  canals.  In  surface  view  these  cells  are  elongated 
and  show  wavy  walls  which  are  perforated  by  distinct  pores  of  an 
angular  to  rounded  outline  (Fig.  12). 
Fig.  9.  Transverse  section  through  representative  portions  of  the  pericarp  of  the  Honey 
Dew  Melon.  Epicarp  (ep) ;  outer  region  of  mesocarp  showing  parenchyma  cells  of 
ripened  receptacle  (mes1) ;  inner  region  of  mesocarp,  composed  of  parenchyma  cells  of 
ripened  ovarian  wall  (mes2) ;  sieve  tubes  (s)  and  spiral  tracheae  (t)  of  a  bi-collateral

cells  are  surrounded  by  7  irregular  shaped  neighboring  cells.  The  regular  epidermal 
cells  are  outside  of  these  (highly  magnified).
