MEDICINAL  PLANTS  WHICH  ARE  CULTIVATED. 
The  following  are  some  of  the  plants  that  have  been  grown  suc- 
cessfully in  this  country,  both  on  a  small  and  a  large  scale  :  Mr. 
Henry  N.  Rittenhouse,  Philadelphia,  has  grown  licorice  for  years 
in  an  ordinary  city  yard.  In  this  connection  it  is  interesting  to 
remember  that  a  species  of  glycyrrhiza  {G.  lepidota)  is  quite  common 
in  certain  parts  of  the  West,  from  Minnesota  to  California,  and  it 
is  not  unlikely  that  Glycyrrhiza  glabra  would  be  easily  naturalized. 
Mr.  C.  B.  Allaire  has  successfully  raised  colocynth  in  New  Mexico 
from  Trieste  seed. 
Spanish  saffron  has  been  grown  successfully  according  to  letters
