In  fresh  Lupulin  more  light  yellow  colored  secretion  hairs  than  in 
old.  In  latter  there  are,  browner  or  grayish-brown  resinous  masses 
replacing  the  light  yellow  oil.  The  amount  of  Hamulus  fragments 
should  not  be  too  large  in  good  quality.    See  No.  537, 
377.  Santonica. — See  No.  350. 
B.     SECRETION  CELLS  OR  RESERVOIRS. 
378.  Aurantii  Amari  Cortex. — See  No.  206,  crystals  of  calcium 
oxalate. 
379.  Aurantii  Dulcis  Cortex. — See  No.  207,  crystals  of  calcium 
oxalate. 
380.  Inula. — See  No.  368,  Inulin  masses  or  crystals, 
381.  Limonis  Cortex. — See  No.  208,  crystals  of  calcium  oxalate. 
382.  Macis. — A  peculiar  starch  (becomes  red  with  iodine  and 
called  "  dextrin  starch  ")  in  small  irregular  particles  ;  yellowish  (oil) 
and  reddish  (resin)  secretion  cells  (75  ;  few  ducts;  H2S04  stains 
contents  of  secretion  cells  bright  red ;  KOH  stains  contents  of 
secretion  cells  a  yellow.  Bombay  mace  gives  with  H2SQ4  a  yellow- 
ish reaction  ;  the  oil  secretion  cells  and  "  dextrin  starch  "  grains 
are  possibly  larger;  the  epidermal  cells  are  radially  elongated  and 
the  collenchymatic  layer  underneath  may  be  wanting  in  Bombay 
mace.

386.  Cocoa  Shells. — Little  or  no  starch;  oil  globules;  character- 
istic brownish  adhesive  fragments,  possessing  more  or  less  hexag- 
onal epidermal  cells ;  peculiar  small  tabular  mucilage  cells  and  a 
layer  of  nearly  isodiametric  stone  cells  (10  x  10  /x)  the  walls  of 
which  are  4  ^  thick. 
387.  Canella  alba. — Crystals,  starch,  secretion  reservoirs.  See  No. 
244. 
388.  Capsicum. — Small  starch  grains  might  not  be  observed  ;
