melting  point,  render  thin  layers  of  the  wax  brittle,  and  are  mostly 
soluble  in  alcohol.    The  wax  is  used  in  ointments  and  plasters. 
Cipres  comun,  Cupressus  sempervirens,  Lin.,  and  Cipres  de  Mexico, 
Cupr.  Benthami,  Gordon.  The  astringent  cones  are  incorrectly  called

tions. 
Ciruelillo,  Bunchosia  lanceolata,  B otter i ;  Malpighiacese ;  in  the 
State  of  Vera  Cruz.  The  root  bark  yields  an  astringent  extract 
resembling  kino. 
Ciruelo  agrio,  Spondias  Mombin,  Lin. ;  Terebinthaceae ;  in  hot 
regions  of  Mexico.  The  comestible  fruit  has  an  acidulous  and  resinous 
taste. 
Ciruelo  de  Mexico,  Spondias  purpurea,  Lin.  The  fruit  is  smaller 
than  the  preceding,  and  has  a  sweet,  somewhat  acidulous,  resinous  and 
balsamic  taste ;  comestible. 
Clavillo,  Juliana  caryophyllata,  La  Llave ;  Zygophyllacese ;  in 
Tlalpam  and  other  localities.    The  leaves  are  stimulant. 
Coclearia,  Cochlearia  officinalis,  Lin.;  Cruciferse.  In  its  place, 
Lepidium  latifolium,  Lin.^  is  used  in  Mexico  as  an  antiscorbutic,  the 
expressed  juice  being  given  in  doses  of  60  to  150  Gm.  a  day. 
Coco,  Cocos  nucifera,  IJn. ;  Palmse;  in  hot  districts  of  Mexico. 
The  roots  are  used  in  diarrhoeas  for  their  astringent  properties,  the 
pith  and  terminal  bud  for  food,  the  flowers  for  their  pectoral  proper- 
ties, and  the  green  fruit  as  a  hemostatic ;  the  fermented  juice  furnishes 
a  very  agreeable  liquor.  The  uses  of  the  cocoa  nut  and  of  the  oil  are 
well  known. 
Colchicum  alpinum,  De  Gaud.;  is  met  with  in  Mexico,  according 
to  Oliva,  and  appears  to  have  the  same  properties  as  Colch.  autumnale. 
Colorin,  Erythrina  coralloides,  Flor.  Mex.  ined. ;  Leguminosse ;  in 
Mexico  and  South  America.  The  seeds  are  elliptic,  smooth,  glossy, 
coral-red,  with  a  salient  longitudinal  line  on  the  back^  and  with  a 
white  hilum,  surrounded  with  a  black  border.  The  analysis  by  Rio  de 
la  Loza  showed  these  seeds  to  contain  13'35  solid  and  liquid  fat,  0'32 
resin  soluble  in  ether,  13'47  resin  soluble  in  alcohol,  1*61  erythroco- 
ralloidine,  an  alkaloid,  5*60  albumen,  0*83  gum,  1-55  sugar,  0*42 
organic  acid,  15*87  starch,  7*15  moisture  and  39*15  inorganic  matter 
(and  cellulose?).  The  seeds  are  very  poisonous.  The  flowers  are  used 
for  food  and  the  white  wood  for  bungs,  and  in  San  Luis  Potosi  for 
making  various  figures.
