  So 
  far 
  as 
  I 
  know 
  the 
  Lilium 
  candidum 
  is 
  exempt 
  from 
  the 
  

   disease 
  in 
  Bermuda, 
  but 
  this 
  species 
  is 
  only 
  occasionally 
  

   grown 
  there, 
  and 
  then 
  with 
  only 
  a 
  few 
  together. 
  Under 
  sim- 
  

   ilar 
  circumstances 
  the 
  longiflorum 
  also 
  is 
  generally 
  exempt 
  

   the 
  plants 
  in 
  the 
  fields 
  alone 
  suffering. 
  The 
  true 
  loncriflorum 
  

   IS 
  not 
  considered 
  to 
  be 
  as 
  susceptible 
  to 
  the 
  disease 
  as 
  the 
  

   Harnsii. 
  Since 
  Marshall 
  Ward 
  has 
  described 
  the 
  Botrytis 
  

   and 
  Its 
  method 
  of 
  growth 
  in 
  so 
  complete 
  a 
  manner, 
  it 
  would 
  

   be 
  superfluous 
  for 
  me 
  to 
  enter 
  upon 
  a 
  detailed 
  description 
  of 
  

   It. 
  I 
  shall 
  therefore, 
  give 
  but 
  a 
  brief 
  summary 
  of 
  the 
  main 
  

   tacts 
  in 
  Its 
  life 
  history, 
  as 
  I 
  have 
  observed 
  them'.
