The  microscopical  characters,  however,  have  not  been  so  fully 
investigated.  But,  at  the  beginning  of  this  article,  the  author 
wishes  to  call  attention  to  a  slight  difference  which  was  observed  in 
the  fruit  (or  berry,  as  it  is  called),  obtained  from  two  sections  of  the 
country.  In  the  specimens  obtained  from  the  South,  mainly 
Georgia  and  Florida,  the  calyx,  though  adherent,  was  recurved, 
while  the  berries  gathered  near  Philadelphia  had  the  calyx  adhering 
to  the  fruit. 
A  transverse  section  of  the  root  {Fig.  4)  shows  it  to  have  a  con- 
centric structure  caused  by  irregular,  alternating  zones  of  wood-

parenchyma  and  vascular  tissues.  The  cork  tissue  replacing  the  epi- 
dermis is  composed  of  about  three  layers  of  cells,  with  the  rough 
fissured  remains  of  older  cork  cells  exterior.  The  cork  meristem  in 
the  root,  as  well  as  in  the  stem,  shows  quite  plainly.  The  paren- 
chyma cells  of  the  cortex  are  larger  in  the  middle  -bark  than  near 
the  epidermis,  becoming  very  much  smaller  and  elongated  longi- 
tudinally near  the  cambium  zone,  while  in  the  outer  and  inner  por- 
tions of  the  cortex  they  are,  from  mutual  pressure,  much  distorted 
and  elongated  tangentially.    The  ducts  of  the  xylem  are  large  and
