  Ever-sporting 
  Varieties 
  

  

  changed 
  at 
  once, 
  the 
  stems 
  grow 
  longer 
  and 
  

   of 
  a 
  deeper 
  green. 
  Intermediates 
  occur, 
  but 
  

   notwithstanding 
  this 
  the 
  two 
  extremes 
  consti- 
  

   tute 
  clearly 
  antagonistic 
  types. 
  

  

  The 
  flora 
  of 
  the 
  deserts 
  is 
  known 
  to 
  exhibit 
  

   a 
  similar 
  divergent 
  type. 
  Or 
  rather 
  two 
  types, 
  

   one 
  adapted 
  to 
  paucity 
  of 
  water, 
  and 
  the 
  other 
  

   to 
  a 
  storage 
  of 
  fluid 
  at 
  one 
  season 
  in 
  order 
  to 
  

   make 
  use 
  of 
  it 
  at 
  other 
  times, 
  as 
  is 
  the 
  case 
  with 
  

   the 
  cactuses. 
  Limiting 
  ourselves 
  to 
  the 
  alter- 
  

   nate 
  group, 
  we 
  observe 
  a 
  rich 
  and 
  dense 
  branch- 
  

   ing, 
  small 
  and 
  compact 
  leaves 
  and 
  extraordi- 
  

   narily 
  long 
  roots. 
  Here 
  the 
  analogy 
  with 
  the 
  

   alpine 
  varieties 
  is 
  manifest, 
  and 
  the 
  dryness 
  

   of 
  the 
  soil 
  evidently 
  affects 
  the 
  plants 
  in 
  a 
  sim- 
  

   ilar 
  way, 
  as 
  do 
  the 
  conditions 
  of 
  life 
  in 
  alpine 
  

   regions. 
  The 
  question 
  at 
  once 
  comes 
  up 
  as 
  to 
  

   whether 
  here 
  too 
  we 
  have 
  only 
  instances 
  of 
  

   partial 
  variability, 
  and 
  whether 
  many 
  of 
  the 
  

   typical 
  desert-species 
  would 
  lose 
  their 
  pecu- 
  

   liar 
  character 
  by 
  cultivation 
  under 
  ordinary 
  

   conditions. 
  The 
  varieties 
  of 
  Monardella 
  ma- 
  

   crantha, 
  described 
  by 
  Hall, 
  from 
  the 
  San 
  Ja- 
  

   cinto 
  Mountain, 
  CaL, 
  are 
  suggestive 
  of 
  such 
  

   an 
  intimate 
  analogy 
  with 
  the 
  cases 
  studied 
  by 
  

   Bonnier, 
  that 
  it 
  seems 
  probable 
  that 
  they 
  might 
  

   yield 
  similar 
  results, 
  if 
  tested 
  by 
  the 
  same 
  

   method. 
  

  

  Leaving 
  now 
  the 
  description 
  of 
  these 
  special
