  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Endogenous  \En*dog"e*nous\,  a. 
  1.  (Bot.)  Increasing  by  internal  growth  and  elongation  at  the 
  summit,  instead  of  externally,  and  having  no  distinction 
  of  pith,  wood,  and  bark,  as  the  rattan,  the  palm,  the 
  cornstalk. 
 
  2.  (Biol.)  Originating  from  within;  increasing  by  internal 
  growth. 
 
  {Endogenous  multiplication}  (Biol.),  a  method  of  cell 
  formation,  seen  in  cells  having  a  cell  wall.  The  nucleus 
  and  protoplasm  divide  into  two  distinct  masses;  these  in 
  turn  become  divided  and  subdivided,  each  division  becoming 
  a  new  cell,  until  finally  the  original  cell  wall  is 
  ruptured  and  the  new  cells  are  liberated  (see 
  {Segmentation},  and  Illust.  of  {Cell  Division},  under 
  {Division}).  This  mode  of  growth  is  characteristic  of  many 
  forms  of  cells,  both  animal  and  vegetable.
