Jaearanda  proeera,  Sprengel. — The  dry  leaves,  examined  by  Dr.  J. 
Different  forms  of  the  leaflets  of  Caroba,  natural  size. 
Moeller,  are  of  various  shades  of 
light  green  and  brown,  and  variable 
in  size  and  shape ;  but  there  are  in- 
termediate forms,  agreeing  in  all 
other  characters,  which  renders  it 
probable  that  the  drug  is  derived 
from  one  species  only.  They  are 
assymetric,  particularly  near  the 
base,  are  somewhat  leathery,  slightly 
revolute,  the  upper  surface  glossy, 
apparently  smooth,  the  lower  surface 
on  the  veins  and  near  the  margin 
velvety  hairy ;  the  petioles  are  oc- 
casionally short,  and  the  secondary 
nerves  anastomosing  near  the  mar- 
gin. The  cuticle  of  the  upper  sur- 
face is  thicker  than  upon  the  lower 
surface,  the  palissade  layer  is  simple, 
the  mesophyll  rather  dense.  The 
epidermis  consists  of  sinuate  cells
