NOTES  ON  SOME  NORTH  AMERICAN  MEDICINAL 
PLANTS. 
In  a  paper  bearing  the  same  title  as  the  present  one,  which  I  pre- 
sented last  year  (see  Am.  Jour.  Pharm.  1 890,  p.  331),  some  account  of 
Colorado  cough-root  was  given,  and  it  was  suggested  that  it  was, 
probably,  derived  from  a  species  of  Ligusticum.  Shortly  after  the 
publication  of  the  paper  my  supposition  was  confirmed  by  a  letter 
from  Mr.  John  Kochan,  of  Denver,  who  stated  that  "  Mr.  Ebert  col- 
lected and  identified  the  plant  in  1888,  as  well  as  myself  in  1889, 
mention  of  which  is  made  Jn  Botanical  Gazette,  vol.  14,  p.  278 
(1889)."    The  reference  alluded  to  reads  as  follows: 
Ligusticum  filicinum,  Watson,  was  collected  in  great  abundance 
near  Lake  City,  Colorado,  by  E.  J.  Ebert,  in  1888,  and  in  the  moun- 
tains back  of  Denver,  by  John  Kochan,  in  July,  1889.  This  is  the 
"Osha"  of  the  Indians,  who  use  its  very  large  aromatic  roots.  It 
was  referred  to  L.  apiifolium  by  Rothrock  in  report  of  Wheeler's 
Expedition,  who  collected  it  about  Twin  Lakes,  Colorado. 
The  origin  of  Colorado  cough-root  being  established,  another 
interesting  question  is  opened  as  to  the  identity  of  this  Colorado 
Osha  with  the  Osha  from  New  Mexico,  described  by  Wm.  Procter 
from  specimens  received  from  Jacob  Krummeck,  Santa  Fe,  N.  M. 
(see  American  Journal  of  Pharmacy,  1867,  p.  202).  From  incom- 
plete botanical  specimens  sent  by  Krummeck,  Elias  Durand  {ibid., 
1868,  p.  106)  referred  the  probable  origin  of  this  root  to  Daucosma
