Londinensis,  apud  vicum  Chelsea,  cultarum,  published  by  James  Lowe 
Wheeler  in  1830,  affords  evidence  that  these  instructions  were 
carried  into  effect.  The  author  in  that  work  adopted  the  system  of 
Linne  in  the  main  text,  but  this  was  supplemented  by  a  Synopsis 
Plantarum  Medicinalium>  secundum  Systema,  D.  Jussieu,  dispdsi- 
tarum,  and  the  class  and  order  of  Jussieu's  Genera  Plantarum ,  as 
well  as  Linne 's  Ordo  Naturalis,  were,  moreover,  mentioned  under 
each  genus  in  the  portion  classified  according  to  the  "  sexual "  sys- 
tem. The  arrangement  of  the  plants  in  the  garden,  however,  seems 
to  have  undergone  no  change  until  the  advent  of  Lindley,  for  Ander- 
son, the  gardener,  was  stubbornly  attached  to  the  Linnean  creed, 
and  refused  to  adopt  any  other.  But  when  Lindley  came  upon  the 
scene  Anderson  was  forced  to  give  way,  and  Lindley's  system  was 
gradually  introduced.  It  is,  nevertheless,  interesting  to  note  that 
Lindley  himself  realized  that  his  system  left  much  to  be  desired,  and 
he  ultimately  almost  abandoned  it  in  his  lectures.  He  saw  clearly 
that  all  attempts  to  arrange  a  natural  system  in  a  consecutive  series 
of  natural  orders  must  result  in  a  series  of  compromises,  and  he 
therefore  preferred  to  deal  with  the  orders  in  natural  groups  which 
he  termed  Nixus  or  Tendencies,  and  Cohorts  or  Alliances.  This 
attitude  is  curiously  reflected  in  his  Flora  Medicat  published  in  1838. 
In  the  preface  to  that  work  he  says:  "  In  the  present  state  of  sys- 
tematical Botany  no  two  writers  upon  classification  can  agree 
respecting  the  exact  sequence  in  which  the  natural  orders  of  plants 
should  follow  each  other.  By  some  the  plan  of  Jussieu  is  adopted, 
by  others  that  of  De  Candolle,  and  by  many  the  systems  of  End- 
licher,  of  the  author  of  this  work,  of  Von  Martius,  ot  Schultz,  or 
even  of  Reichenbach,  may  be  preferred.  This  can  only  be  accounted 
for  upon  the  supposition  that  the  systems  of  all  these  authors  are 
equally  false."  As  a  result,  and  in  order  "  to  enable  the  reader  of 
this  book  to  suit  his  own  convenience  in  the  arrangement  of  the 
matter,  the  work  is  so  printed  that  the  different  natural  orders  may 
be  cut  asunder  and  re-arranged  at  the  pleasure  of  the  possessor." 
The  rearrangement  of  the  plants  in  the  garden  was  considerably 
delayed  owing  to  the  persistent  hostility  of  Anderson  to  Lindley's 
wishes,  but  the  Professor  of  Botany  was  equally  insistent  on  having 
these  complied  with,  so  that  pressure  was  brought  to  bear  on 
Anderson  with  the  result  that  a  new  arrangement  of  the  medicinal 
plants  was,  so  far  as  possible,  completed  in  1839,  and,  in  1847,  tne
