HAPLOPAPPUS  BAYLAHUEN— C.  GAY* 
\_Hysterionica  Baylahuen  (Gay)  Baillon.] 
By  Harry  Kahn,  Phar.  M. 
This  plant,  which  is  indigenous  to  Chili,  has  until  recently  been 
little  known  to  science.  The  February  28,  1889,  issue  of  the 
Bulletin  General  de  Tkerapeutique,  p.  160,  contains  a  paper  by  Dr# 
G.  Baille,  and  in  the  Druggists'  Bulletin,  4,  39,  may  be  found  a 
paper,  with  an  illustration,  by  Dr.  H.  Rusby. 
Gay's  description  of  the  plant  under  consideration,  as  translated 
by  Rusby,  is  as  follows :  Stem  woody,  cylindrical,  ramose,  glutin- 
ous and  lightly  sulcate,  the  same  as  the  branches,  which  are 
elongated,  and  very  glabrous,  nearly  naked  in  the  upper  part,  all 
terminated  by  a  single  head.  Leaves  coriaceous,  thick,  with  a  base 
persistent  upon  the  stem,  much  crowded  below  the  branches, 
obovate  spatulate,  nearly  cuneiform,  narrowed  at  the  base,  half 
clasping,  slightly  wavy  above  the  middle  ;  they  are  bordered  by 
thick  teeth,  glutinous,  very  glabrous  on  both  faces,  an  inch  long  at 
the  most  and  4  to  6  lines  wide.  Involucre  campanulate,  formed  of 
some  four  rows  of  scales,  the  exterior  of  which  are  foliaceous,  ovate 
dentate,  the  interior  lance-linear,  acuminate,  entire,  scariose,  slightly 
membranous  at  the  margins,  nearly  as  large  as  the  disk  flowers, 
longer  than  the  ligules.  Akenes  very  glabrous  ;  pappus  of  a  tawny 
reddish  color. 
*  My  thanks  are  due  to  Parke,  Davis  &  Co.,  of  Detroit,  Mich.,  for  the  very 
liberal  supply  of  drug  for  this  analysis.
