  1. 
  LiLiuM 
  Washingtonianum, 
  Kellogg, 
  

  

  Occurs 
  on 
  the 
  Cuyumaca 
  Mountains, 
  in 
  San 
  Diego 
  County, 
  its 
  most 
  southern 
  

   limit 
  known 
  at 
  present 
  ; 
  northward 
  along 
  the 
  western 
  slope 
  of 
  the 
  Sierra 
  Ne- 
  

   vada, 
  between 
  3,.500 
  to 
  6,000 
  feet 
  altitude 
  ; 
  in 
  Oregon 
  to 
  the 
  Columbia 
  River, 
  and 
  

   on 
  the 
  Coast 
  Ranges 
  north 
  of 
  San 
  Francisco, 
  especially 
  in 
  the 
  eastern 
  parts 
  of 
  

   Mendocino 
  and 
  Humboldt 
  Counties. 
  In 
  all 
  localities 
  named, 
  it 
  occurs 
  either 
  

   on 
  ridges 
  or 
  on 
  lightly 
  shaded 
  slopes 
  of 
  ridges, 
  having 
  a 
  porous 
  loose 
  soil, 
  resting 
  

   on 
  a 
  gravelly 
  subsoil. 
  At 
  no 
  time 
  have 
  I 
  met 
  with 
  a 
  plant 
  of 
  this 
  species 
  in 
  

   a 
  soil 
  whose 
  drainage 
  was 
  not 
  perfect 
  ; 
  and, 
  when 
  found 
  on 
  a 
  slope, 
  did 
  not 
  

   face 
  towards 
  some 
  point 
  between 
  east 
  and 
  south. 
  The 
  pale, 
  loosely-scaled, 
  

   ovoid 
  bulb 
  is 
  generally 
  found 
  at 
  a 
  depth 
  of 
  from 
  twelve 
  to 
  twenty 
  inches. 
  

   The 
  height 
  of 
  the 
  stem, 
  the 
  number 
  of 
  whorls 
  and 
  flowers 
  on 
  a 
  single 
  stem, 
  

   vary 
  very 
  much 
  according 
  to 
  soil, 
  exposition, 
  and 
  age 
  of 
  the 
  bulb. 
  

  

  Much 
  has 
  been 
  said 
  about 
  the 
  difficulty 
  of 
  cultivating 
  this 
  beautiful 
  species. 
  

   I 
  willingly 
  confess 
  that 
  I 
  have 
  also 
  met 
  with 
  many 
  reverses, 
  until 
  I 
  paid 
  proper 
  

   attention 
  to 
  its 
  habits 
  and 
  habitats. 
  If 
  the 
  bulb 
  is 
  planted 
  at 
  a 
  depth 
  of 
  from 
  

   eight 
  to 
  twelve 
  inches 
  in 
  a 
  loose, 
  somewhat 
  gravelly 
  soil, 
  having 
  perfect 
  drainage, 
  

   there 
  is 
  no 
  difficulty 
  in 
  obtaining 
  satisfactory 
  results. 
  Although 
  there 
  is 
  positively 
  

   no 
  specific 
  difference 
  between 
  bulbs 
  and 
  plants, 
  collected 
  either 
  on 
  the 
  Sierras 
  

   or 
  on 
  the 
  Coast 
  Ranges, 
  yet 
  I 
  found 
  that 
  bulbs 
  from 
  the 
  Coast 
  Ranges 
  would 
  

   always 
  bloom 
  more 
  readily 
  in 
  San 
  Francisco 
  (in 
  cool 
  houses) 
  than 
  those 
  from 
  

   the 
  Sierras. 
  The 
  reason 
  is 
  obvious 
  ; 
  but 
  it 
  would 
  be 
  interesting 
  to 
  know 
  if 
  

   the 
  same 
  holds 
  good 
  at 
  other 
  places 
  than 
  San 
  Francisco. 
  The 
  flowers 
  are 
  very 
  

   fragrant, 
  and 
  change 
  gradually 
  from 
  a 
  pure 
  white 
  to 
  various 
  shades 
  of 
  purple 
  

   or 
  lilac 
  ; 
  the 
  purplish-red 
  spots 
  are 
  rather 
  minute. 
  The 
  figure 
  given 
  in 
  Mons. 
  

   Louis 
  van 
  Houtte's 
  Flore 
  (Vol. 
  XIX.) 
  is 
  a 
  very 
  correct 
  representation 
  of 
  this 
  

   species. 
  

  

  2. 
  LiLIUM 
  HUMBOLDTII, 
  RoCzl. 
  

  

  L. 
  Bloomerianum, 
  Kellogg. 
  

   This 
  large 
  species 
  has 
  apparently 
  a 
  far 
  less 
  wider 
  range 
  than 
  the 
  preceding. 
  

   It 
  occurs 
  mainly 
  on 
  the 
  more 
  elevated 
  portions 
  of 
  the 
  foot-hills 
  of 
  the 
  Sierras, 
  

   from 
  2,500 
  to 
  nearly 
  3,500 
  feet 
  altitude, 
  evidently 
  requiring 
  a 
  greater 
  amount 
  

   of 
  heat 
  to 
  develop 
  its 
  full 
  size 
  and 
  beauty 
  than 
  the 
  first-named 
  species. 
  The 
  

   soils 
  in 
  which 
  its 
  bulb 
  is 
  found 
  are 
  of 
  a 
  rather 
  compact 
  nature, 
  consisting 
  of 
  

   clay, 
  with 
  an 
  admixture 
  of 
  broken 
  rocks, 
  and 
  a 
  small 
  portion 
  of 
  vegetable 
  

   mould. 
  Growing 
  in 
  open 
  park 
  land 
  or 
  land 
  entirely 
  cleared 
  off, 
  and 
  therefore 
  

   exposed 
  to 
  a 
  hot 
  and 
  burning 
  sun, 
  and 
  surrounded 
  by 
  a 
  dry 
  and 
  exsiccating 
  air,
