46  The  Apocynacece  in  Materia  Medica.  {^aiuaJyS"1, 
In  the  appendix  to  the  Pharmacopoeia  of  India,  by  Waring,  Wight 
has  established  the  distinctive  characters  of  these  three  trees  in  which 
the  size  is  the  same,  the  barks  latex  bearing  and  scaling  off  in  strips ; 
the  flowers  are  white,  and  the  inflorescences  identical,  the  follicles  long 
and  slender  and  united  in  twos,  the  seeds  garnished  by  tufts  of  white 
hairs.  In  Holarrhena  and  in  Wrightia  the  leaves  are  opposite,  oval, 
rounded  at  the  base  and  attenuated  at  the  apex,  while  in  the 
Alstonia  the  leaves  are  verticillate,  attenuated  at  the  base  and 
rounded  at  the  summit.  In  Holarrhena  the  tube  of  the  corolla  is 
two  or  three  times  longer  than  the  calyx,  twisted  to  the  left  in 
aestivation,  with  naked  throat,  without  appendages,  stamens  included 
and  inserted  in  the  dilated  part  of  the  tube.  In  the  Wrightia  tinc- 
toria  the  tube  is  relatively  shorter,  prefloration  twisted  to  the  right, 
the  sagittate  stamens  exserted,  forming  a  cone  about  the  stigma, 
and  a  crown  of  filamentous  glands  laciniate,  velvety.  The  dispo- 
sition of  the  hairs  borne  by  the  seed  is  likewise  quite  characteristic  ; 
in  the  Holarrhena  the  tuft  of  delicate  silky  white  hairs  is  borne  at 
the  upper  extremity  of  the  seed ;  in  the  Wrightia  it  is  the  lower 
extremity,  and  in  Alstonia  both  extremities  are  ornamented. 
Holarrhena  antidysenterica,  Rob.  Br.  (Nerium  antidys  enteric  a  y 
L.  (in  part).  Echites  antidysenterica,  Roxb.  Chonemorpha  anti- 
dysenterica, G.  Don.  Holarrhena  pubescens,  Wall.  H  Codaga, 
G.  Don.  H.  malaccensis,  Wight).  This  is  a  shrub,  or  at  most  a 
small  tree,  of  which  certain  forms  are  glabrous  and  others  tomen- 
tose,  abundant  in  the  mountains  and  dry  forest  regions  of  India.  It 
is  known  in  the  various  regions  under  a  multitude  of  vernacular 
names.1
