  strength 
  of 
  the 
  plant 
  and 
  the 
  degree 
  of 
  develop- 
  

   ment 
  of 
  its 
  anomaly. 
  The 
  same 
  holds 
  good 
  with 
  

   other 
  monstrosities, 
  and 
  badly 
  nourished 
  speci- 
  

   mens 
  of 
  rich 
  races 
  with 
  twisted 
  or 
  fasciated 
  

   stems 
  always 
  tend 
  to 
  reversion. 
  This 
  rever- 
  

   sion, 
  however, 
  is 
  not 
  necessarily 
  correlated 
  with 
  

   the 
  hereditary 
  percentage 
  and 
  therefore 
  does 
  

   not 
  always 
  indicate 
  a 
  lessening 
  of 
  the 
  degree 
  of 
  

   inheritance. 
  This 
  shows 
  that 
  even 
  in 
  those 
  

   cases 
  an 
  improvement 
  may 
  be 
  expected, 
  if 
  only 
  

   the 
  means 
  can 
  be 
  found 
  to 
  subject 
  the 
  twisted 
  

   and 
  the 
  fasciated 
  races 
  to 
  the 
  same 
  sharp 
  test 
  

   as 
  the 
  tricotylous 
  varieties. 
  

  

  Much 
  remains 
  to 
  be 
  done, 
  and 
  the 
  principle 
  of 
  

   the 
  selection 
  of 
  parents 
  according 
  to 
  the 
  average 
  

   constitution 
  of 
  their 
  progeny 
  seems 
  to 
  be 
  one 
  of 
  

   the 
  most 
  promising 
  in 
  the 
  whole 
  realm 
  of 
  varia- 
  

   bility. 
  

  

  Besides 
  tricotylous, 
  the 
  syncotylous 
  seed- 
  

   lings 
  may 
  be 
  used 
  in 
  the 
  same 
  way. 
  They 
  

   are 
  more 
  rarely 
  met 
  with, 
  and 
  in 
  most 
  instances 
  

   seem 
  to 
  belong 
  only 
  to 
  the 
  unpromising 
  half- 
  

   races. 
  The 
  black 
  bindweed 
  (Polygonum 
  Con- 
  

   volvulus), 
  the 
  jointed 
  charlock 
  (RapJianus 
  Rap- 
  

   hanistrum), 
  the 
  glaucous 
  evening-primrose 
  

   (Oenothera 
  glauca) 
  and 
  many 
  other 
  plants 
  seem 
  

   to 
  contain 
  such 
  half-races. 
  On 
  the 
  other 
  hand 
  

   I 
  found 
  a 
  plant 
  of 
  Centrantlms 
  macrosiplion 
  

   yielding 
  as 
  much 
  as 
  55$ 
  of 
  syncotylous 
  chil-
