sources  of  the  Missouri  to  the  falls  of  the  Columbia,  and  from  the 
380  to  the  480  of  N.  latitude."  (Douglas.) 
Between  the  thin  and  membranous  epidermis  of  the  seed  and  the 
opaque  yellowish  inner  coat  is  a  granulated  resinous  pulp,  half  a  line 
thick,  deep  purple  in  color,  and  intensely  and  persistently  bitter, 
which  deserves  attention  either  as  a  coloring  or  medicinal  substance. 
It  imparts  its  bitterness  to  water  and  alcohol  without  discoloring 
either  menstruum,  one  seed  being  sufficient  to  render  a  tumblerful 
of  water  undrinkable.  The  bitter  principle  is  apparently  distinct 
from  the  coloring  matter. 
Note. — The  small  amount  of  material  sent  with  the  above  descrip- 
tion precluded  a  satisfactory  examination.  Alcohol  removed  the 
bitter  principle  with  some  fat,  and  in  attempting  to  separate  the 
latter  by  agitating  the  aqueous  acidified  solution  with  ether  the  bitter 
principle  was  also  removed;  this  would  almost  exclude  itfrom  being 
an  alkaloid,  but  further  tests  could  not  be  tried  to  decide  this.  It 
gave  no  reactions  indicating  a  glucoside.  It  is  hoped  that  more  of 
the  material  will  be  sent,  on  which  to  make  a  further  examination.

This  like  the  preceding  food  plants  described  in  this  Journal  was 
received  from  Dr.  V.  Havard,  U.  S.  Army  Surgeon,  at  Fort  Russell, 
Wyoming.    He  furnished  with  the  material  the  following  report : 
"  Carum  Gairdneri,  Benth.  and  Hook.  (Yamp  or  Yampah,  Yep 
or  Yepah)  of  the  Parsley  Family  (Umbelliferae).  Tall,  erect,  bien- 
nial herb,  1  to  4  feet  high,  rather  smooth,  with  few  pinnate  leaves 
of  3  to  7  entire  leaflets,  and  white  flowers;  the  involucre  of  a  single 
leaflet  and  the  involucels  of  several  bracts. 
"  Found  mostly  on  low  timbered  bottoms  from  the  western  fork 
of  Laramie  River,  Wyo.,  apparently  its  most  eastern  habitat, 
through  the  Rocky  Mountains  to  Oregon  and  Washington  ;  south- 
ward it  extends  to  Utah,  Nevada  and  South  California.    It  gives
