with  the  stylar  cushion  and  both  styles,  very  slightly  cleft.  The  ribs 
are  somewhat  broad,  the  grooves  strongly  crowded  together.  These 
are  pervaded  through  their  entire  length  by  dark-brown  oil  passages, 
which  are  especialy  prominent  in  the  dorsal  region  and  extend  in 
arcuate  fashion. 
As  examined  with  a  hand  lens,  cross  sections  show  the  fruit  wall 
to  be  oval,  only  nearly  straight  on  the  partition  surface.  The  ribs 
are  broad  and  very  strongly  projected;  both  the  marginal  costal  are, 
moreover,  slightly  winged.  In  the  middle  of  the  inter-rib  regions  is 
an  oil  reservoir  with  reddish-brown  contents ;  on  the  commissural 
surface  are  two  such  secretory  passages.  The  endosperm  is  rounded 
dorsally  and  slightly  concave  in  the  region  of  the  raphe. 
Under  the  microscope,  the  outer  epidermal  cells  are  slightly  tan- 
gentially  elongated,  over  the  ribs  quadratic.  Especially  here  the 
outer  membrane  shows  small  warts,  owing  to  the  parallel  cuticular 
striae  as  observed  in  surface  section.  The  endocarp  shows  tan- 
gentially  elongated  cells.  The  inner  layer  of  the  mesocarp  (6o,u 
broad  and  up  to  15  cell  rows  thick)  is  built  of  tangentially  elongated, 
strongly  compressed  cells.  The  outermost  are  finely  reticulately 
thickened  and  surround  the  fruit  like  a  closed  band.  The  outer 
broader  zone  of  the  middle  region  is  filled  up  with  loose,  very  thin 
walled  parenchyma  tissue.  The  broad  ribs  are  almost  completely 
filled  up  with  finely  reticulately  thickened  tissue  which  exhibits  a 
rounded  form;  its  cells  are  almost  regularly  polygonal,  only  those 
lying  along  the  margin  being  peripherally  elongated.  At  the  site 
adjacent  to  the  rib  ends  lies  the  vascular  bundle  with  a  few  narrow 
spiral  tracheae  which  are  only  distinctly  noticeable  in  longitudinal 
section.  They  are  accompanied  by  narrow-lumened,  obliquely  punc- 
tated and  long  taper-ended  bast  fibers.  All  the  thickened  elements 
are  lignified.  Outside  of  the  fibrovascular  strand  in  each  rib  lies  a 
small  secondary  oil  reservoir  and  at  times  there  is  found  another 
similar  one  alongside  of  the  thickened  tissue.  In  the  middle  of  the 
inter-rib  region,  bounding  the  inner  thickened  mesocarp  zone  lies  a 
rounded  oval  secretory  channel  with  reddish-brown  contents  and 
from  1 10^  long  to  75^  broad.  Both  of  the  vittse  in  the  com- 
missural region  are  somewhat  larger.  The  seed  coat  is  brown- 
walled  and  strongly  collapsed;  only  in  the  raphe  portion  is  it  some- 
what broader  developed  and  shows  a  bending  in  of  the  endosperm. 
The  endosperm  is  uniformly  thickened,  contains  fixed  oil,  aleurone 
and  rosettes  of  calcium  oxalate  from  2—5  /.t  in  diameter.    In  the
