  The 
  same 
  holds 
  good 
  for 
  albida, 
  which 
  ap- 
  

   peared 
  in 
  15 
  specimens, 
  or 
  in 
  0.1$, 
  of 
  the 
  whole 
  

   culture. 
  By 
  careful 
  cultivation 
  these 
  plants 
  

   proved 
  not 
  to 
  be 
  sickly, 
  but 
  to 
  belong 
  to 
  a 
  new, 
  

   though 
  weak 
  type. 
  It 
  was 
  evident 
  that 
  I 
  had 
  

   already 
  seen 
  them 
  in 
  former 
  years, 
  but 
  having 
  

   failed 
  to 
  recognize 
  them 
  had 
  allowed 
  them 
  to 
  be 
  

   destroyed 
  at 
  an 
  early 
  age, 
  not 
  knowing 
  how 
  to 
  

   protect 
  them 
  against 
  adverse 
  circumstances. 
  

   Even 
  this 
  time 
  I 
  did 
  not 
  succeed 
  in 
  getting 
  them 
  

   strong 
  enough 
  to 
  keep 
  through 
  the 
  winter. 
  

  

  Besides 
  these, 
  two 
  new 
  types 
  were 
  observed, 
  

   completing 
  the 
  range 
  of 
  all 
  that 
  have 
  since 
  been 
  

   recorded 
  to 
  regularly 
  occur 
  in 
  this 
  family. 
  

   They 
  were 
  scintillans 
  and 
  gigas. 
  The 
  first 
  

   was 
  obtained 
  in 
  the 
  way 
  just 
  described. 
  The 
  

   other 
  hardly 
  escaped 
  being 
  destroyed, 
  not 
  hav- 
  

   ing 
  showed 
  itself 
  early 
  enough, 
  and 
  being 
  left 
  in 
  

   the 
  bed 
  after 
  the 
  end 
  of 
  the 
  selection. 
  But 
  as 
  

   it 
  was 
  necessary 
  to 
  keep 
  some 
  rosettes 
  through 
  

   the 
  winter 
  in 
  order 
  to 
  have 
  biennial 
  flowering 
  

   plants 
  to 
  furnish 
  seeds, 
  I 
  selected 
  in 
  August 
  

   about 
  30 
  of 
  the 
  most 
  vigorous 
  plants, 
  planted 
  

   them 
  on 
  another 
  bed 
  and 
  gave 
  them 
  sufficient 
  

   room 
  for 
  their 
  stems 
  and 
  branches 
  in 
  the 
  follow- 
  

   ing 
  summer. 
  Most 
  of 
  them 
  sent 
  up 
  robust 
  

   shoots, 
  but 
  no 
  difference 
  was 
  noted 
  till 
  the 
  first 
  

   flowers 
  opened. 
  One 
  plant 
  had 
  a 
  much 
  larger 
  

   crown 
  of 
  bright 
  blossoms 
  than 
  any 
  of 
  the 
  others.
