  reddish 
  or 
  yellowish 
  hues. 
  They 
  are 
  glandular 
  on 
  the 
  margin 
  and 
  

   in 
  some 
  species 
  on 
  the 
  surface 
  also. 
  These 
  scales 
  are 
  generally 
  

   soon 
  deciduous. 
  

  

  The 
  flowers 
  in 
  our 
  species 
  are, 
  with 
  one 
  exception, 
  Cratae-

  , 
  produced 
  in 
  clusters 
  at 
  the 
  ends 
  of 
  short 
  

   leafy 
  terminal 
  or 
  lateral 
  branches. 
  In 
  the 
  earliest 
  species 
  to 
  

   flower 
  in 
  our 
  latitude 
  they 
  appear 
  about 
  the 
  end 
  of 
  the 
  first 
  week 
  

   in 
  May, 
  in 
  the 
  latest, 
  the 
  first 
  week 
  in 
  June, 
  making 
  the 
  flowering 
  

   season 
  about 
  one 
  month 
  long. 
  In 
  nearly 
  all 
  cases 
  the 
  flowers 
  open 
  

   and 
  their 
  petals 
  fall 
  before 
  the 
  leaves 
  are 
  fully 
  developed. 
  The 
  

   flower 
  stems 
  or 
  peduncles 
  may 
  be 
  long 
  or 
  short, 
  simple 
  or 
  

   branched, 
  glabrous 
  or 
  hairy, 
  according 
  to 
  the 
  species. 
  The 
  

   branching 
  peduncles 
  frequently 
  support 
  three 
  flowers 
  each, 
  the 
  

   central 
  flower 
  opening 
  a 
  little 
  earlier 
  than 
  the 
  two 
  lateral. 
  The 
  

   calyx 
  is 
  superior 
  and 
  five 
  lobed, 
  the 
  petals 
  are 
  five, 
  the 
  stamens 
  

   vary 
  from 
  5 
  to 
  20 
  and 
  the 
  pistils 
  from 
  1 
  to 
  5. 
  The 
  stamens 
  

   are 
  normally 
  5, 
  10, 
  15 
  or 
  20 
  in 
  any 
  given 
  species, 
  but 
  by 
  the 
  sup- 
  

   pression 
  of 
  some 
  or 
  the 
  union 
  of 
  two 
  adjacent 
  filaments 
  such 
  

   definite 
  numbers 
  are 
  not 
  always 
  found. 
  Nevertheless 
  the 
  number 
  

   of 
  the 
  stamens 
  is 
  now 
  utilized 
  as 
  a 
  specific 
  character. 
  The 
  color 
  

   of 
  the 
  anthers 
  may 
  be 
  pale 
  yellow 
  or 
  whitish, 
  pink 
  or 
  rosy 
  red, 
  

   purplish 
  red 
  or 
  violaceous, 
  and 
  though 
  these 
  colors 
  are 
  very 
  fleet- 
  

   ing 
  they 
  are 
  recognized 
  as 
  having, 
  in 
  many 
  cases, 
  specific 
  value. 
  

   The 
  calyx 
  lobes 
  are 
  generally 
  tipped 
  with 
  a 
  single 
  gland, 
  their 
  

   margins 
  may 
  be 
  entire 
  or 
  furnished 
  with 
  sessile 
  or 
  stalked 
  glands. 
  

   They 
  are 
  erect 
  in 
  bud 
  but 
  spreading 
  or 
  reflexed 
  in 
  anthesis 
  and 
  in 
  

   some 
  species 
  they 
  later 
  become 
  again 
  erect 
  or 
  incurved. 
  In 
  many 
  

   species 
  they 
  also 
  become 
  red 
  on 
  the 
  inner 
  basal 
  surface 
  as 
  they 
  

   advance 
  in 
  age. 
  They 
  are. 
  sometimes 
  deciduous 
  from 
  the 
  ripe 
  

   fruit, 
  specially 
  in 
  species 
  belonging 
  to 
  the 
  section 
  Tomentosae. 
  

   The 
  petals 
  are 
  nearly 
  always 
  white 
  in 
  our 
  species. 
  In 
  one 
  or 
  two 
  

   they 
  show 
  a 
  tendency 
  to 
  become 
  rosy 
  tinted 
  when 
  they 
  begin 
  to 
  

   wither. 
  They 
  are 
  quickly 
  deciduous. 
  They 
  are 
  sometimes 
  eroded 
  

   or 
  wavy 
  on 
  the 
  edge, 
  and 
  are 
  generally 
  furnished 
  with 
  a 
  short 
  claw 
  

   at 
  the 
  base. 
  

  

  The 
  time 
  of 
  ripening 
  of 
  the 
  fruit 
  extends 
  from 
  the 
  middle 
  of 
  

   August 
  to 
  the 
  middle 
  of 
  October.
