  Ever-sporting 
  Varieties 
  

  

  to 
  poor 
  races, 
  but 
  the 
  magnolias 
  and 
  lime-trees 
  

   are 
  often 
  so 
  productive 
  of 
  ascidia 
  as 
  to 
  suggest 
  

   the 
  idea 
  of 
  ever-sporting 
  varieties. 
  I 
  have 
  

   seen 
  many 
  hundred 
  ascidia 
  on 
  one 
  lime-tree, 
  and 
  

   far 
  above 
  a 
  hundred 
  on 
  the 
  magnolia. 
  They 
  dif- 
  

   fer 
  widely 
  in 
  size 
  and 
  shape, 
  including 
  in 
  some 
  

   cases 
  two 
  leaves 
  instead 
  of 
  one, 
  or 
  are 
  composed 
  

   of 
  only 
  half 
  a 
  leaf 
  or 
  of 
  even 
  still 
  a 
  smaller 
  part 
  

   of 
  the 
  summit. 
  Eich 
  ascidia-bearing 
  varieties 
  

   seem 
  to 
  offer 
  notable 
  opportunities 
  for 
  scientific 
  

   pedigree-cultures. 
  

  

  Union 
  of 
  the 
  neighboring 
  fruits 
  and 
  flowers 
  on 
  

   flower-heads, 
  of 
  the 
  rays 
  of 
  the 
  umbellifers 
  or 
  

   of 
  the 
  successive 
  flowers 
  of 
  the 
  racemes 
  of 
  cab- 
  

   bages 
  and 
  allied 
  genera, 
  seem 
  to 
  be 
  rare. 
  

   The 
  same 
  holds 
  good 
  for 
  the 
  adhesion 
  of 
  foliar 
  

   to 
  axial 
  organs, 
  of 
  branches 
  to 
  stems 
  and 
  

   other 
  cases 
  of 
  union. 
  Many 
  of 
  these 
  cases 
  re- 
  

   turn 
  regularly 
  in 
  each 
  generation, 
  or 
  may 
  at 
  

   least 
  be 
  seen 
  from 
  time 
  to 
  time 
  in 
  the 
  same 
  

   strains. 
  Proliferation 
  of 
  the 
  inflorescence 
  is 
  

   very 
  common 
  and 
  changes 
  in 
  the 
  position 
  of 
  

   staminate 
  and 
  pistillate 
  flowers 
  are 
  not 
  rare. 
  

   We 
  find 
  starting 
  points 
  for 
  new 
  investigations 
  

   in 
  almost 
  any 
  teratological 
  structure. 
  Half- 
  

   races 
  and 
  double-races 
  are 
  to 
  be 
  distinguished 
  

   and 
  isolated 
  in 
  all 
  cases, 
  and 
  their 
  hereditary 
  

   qualities, 
  the 
  periodicity 
  of 
  the 
  recurrence 
  of 
  

   the 
  anomaly, 
  the 
  dependency 
  on 
  external 
  circum-
