  buds 
  which 
  are 
  only 
  slightly 
  protected 
  by 
  scales, 
  but 
  these 
  

   buds 
  are 
  usually 
  small 
  and 
  often 
  more 
  or 
  less 
  hidden 
  under 
  

   the 
  bark, 
  as 
  in 
  the 
  sy- 
  

   ringa 
  (PMladelphus) 
  

   and 
  the 
  thorny 
  honey 
  

   locust 
  (Q-leditsia).

  Buds 
  become 
  

   shoots. 
  If 
  we 
  watch 
  

   the 
  opening 
  and 
  sub- 
  

   sequent 
  growth 
  of 
  a 
  

   bud 
  (figs. 
  76, 
  83, 
  and 
  

   84), 
  we 
  shall 
  find 
  that 
  

   sometimes 
  it 
  develops 
  

   into 
  a 
  leafy 
  shoot; 
  

   that 
  is, 
  it 
  forms 
  the 
  

   beginning 
  of 
  a 
  new 
  

   twig 
  or 
  lengthens 
  out 
  

   the 
  twig, 
  branch, 
  or 
  

   main 
  stem 
  at 
  the 
  tip 
  

   of 
  which 
  it 
  was 
  formed. 
  

   Sometimes 
  it 
  develops 
  

   into 
  a 
  flower 
  or 
  a 
  clus- 
  

   ter 
  of 
  flowers. 
  Some- 
  

   times 
  it 
  produces 
  both 
  

   leaves 
  and 
  flowers. 
  

   Buds, 
  then, 
  are 
  classi- 
  

   fied, 
  according 
  to 
  the 
  

   results 
  of 
  their 
  devel- 
  

   opment, 
  into 
  leaf 
  buds, 
  

   flower 
  buds, 
  and 
  mixed 
  

   buds. 
  And 
  since 
  a 
  flower 
  (as. 
  we 
  shall 
  see 
  

   in 
  Chapter 
  IX) 
  is 
  only 
  a 
  peculiar 
  kind 
  of 
  

   shoot 
  specialized 
  for 
  seed 
  production, 
  we 
  

   may 
  define 
  a 
  bud 
  as 
  an 
  undeveloped 
  shoot.

  Position 
  of 
  buds. 
  Buds 
  are 
  either 
  terminal 
  (growing 
  

   from 
  the 
  tip 
  of 
  the 
  stem) 
  or 
  lateral 
  (growing 
  from 
  its 
  side).
