  Mutations 
  

  

  from 
  the 
  Adirondacks. 
  Through 
  the 
  kindness 
  

   of 
  Dr. 
  MacDougal, 
  of 
  the 
  New 
  York 
  Botanical 
  

   Garden, 
  I 
  received 
  seeds 
  from 
  Sandy 
  Hill 
  near 
  

   Lake 
  George. 
  When 
  the 
  plants, 
  grown 
  from 
  

   these 
  seeds, 
  flowered, 
  they 
  were 
  not 
  a 
  uniform 
  

   lot, 
  but 
  exhibited 
  two 
  distinct 
  types. 
  Some 
  had 
  

   linear 
  petals 
  and 
  thin 
  flower-buds, 
  and 
  in 
  

   others 
  the 
  petals 
  were 
  a 
  little 
  broader 
  and 
  the 
  

   buds 
  more 
  swollen. 
  The 
  difference 
  was 
  small, 
  

   but 
  constant 
  on 
  all 
  the 
  flowers, 
  each 
  single 
  plant 
  

   clearly 
  belonging 
  to 
  one 
  or 
  the 
  other 
  of 
  the 
  two 
  

   types. 
  Probably 
  two 
  elementary 
  species 
  were 
  

   intermixed 
  here, 
  but 
  whether 
  one 
  is 
  the 
  sys- 
  

   tematic 
  type 
  and 
  the 
  other 
  a 
  mutation, 
  remains 
  

   to 
  be 
  seen. 
  

  

  Nor 
  seem 
  these 
  two 
  types 
  to 
  exhaust 
  the 
  range 
  

   of 
  variability 
  of 
  Oenothera 
  cruciata. 
  Dr. 
  B. 
  L. 
  

   Robinson 
  of 
  Cambridge, 
  Mass., 
  had 
  the 
  kind- 
  

   ness 
  to 
  send 
  me 
  seeds 
  from 
  another 
  locality 
  in 
  

   the 
  same 
  region. 
  The 
  seeds 
  were 
  collected 
  in 
  

   New 
  Hampshire 
  and 
  in 
  my 
  garden 
  produced 
  a 
  

   true 
  and 
  constant 
  cruciata, 
  but 
  with 
  quite 
  differ- 
  

   ent 
  secondary 
  characters 
  from 
  both 
  the 
  afore- 
  

   said 
  varieties. 
  The 
  stems 
  and 
  flower-spikes 
  and 
  

   even 
  the 
  whole 
  foliage 
  were 
  much 
  more 
  slender, 
  

   and 
  the 
  calyx-tubes 
  of 
  the 
  flowers 
  were 
  notice- 
  

   ably 
  more 
  elongated. 
  It 
  seems 
  not 
  improbable 
  

   that 
  Oenothera 
  cruciata 
  includes 
  a 
  group 
  of 
  

   lesser 
  unities, 
  and 
  may 
  prove 
  to 
  comprise 
  a
