GRANATUM  (POMEGRANATE).* 
By  John  Uri  Lloyd,  Phar.M. 
Punica  granatum  has  been  found  in  cultivation  from  the  earliest 
historical  times.  It  is  now  found  in  all  warm  countries  of  the 
world,  and  frequently  as  an  ornamental  plant  in  this  country  and 
abroad,  where  it  requires  protection  during  the  winter  season, 
as  it  will  not  endure  the  cold.  It  is  recorded,  e.g.,  that  in  1838 
the  pomegranate  trees  in  the  neighborhood  of  London  were  killed 
by  the  frost.  The  form  generally  grown  as  ornament  is  the  double 
variety,  and  consequently  barren.    The  fruit  of  the  pomegranate
