﻿REPORT 
  OF 
  THE 
  STATE 
  BOTANIST

  into 
  a 
  leaf, 
  a 
  branch 
  or 
  a 
  cluster 
  of 
  flowers 
  the 
  next 
  year. 
  In 
  

   breaking 
  a 
  spine 
  from 
  its 
  branch 
  the 
  leaf, 
  branchlet 
  or 
  flower 
  

   cluster 
  is 
  likely 
  to 
  be 
  torn 
  away 
  with 
  it 
  unless 
  care 
  is 
  taken 
  to 
  

   avoid 
  it. 
  The 
  young 
  spine 
  is 
  often 
  adorned 
  with 
  one 
  or 
  more 
  

   narrow 
  foliaceous 
  bracts 
  which 
  are 
  quickly 
  deciduous. 
  The 
  spines 
  

   of 
  the 
  hawthorn 
  are 
  sometimes 
  elongated 
  and 
  leaf 
  bearing. 
  They 
  

   then 
  appear 
  like 
  a 
  short 
  leafy 
  branch 
  terminating 
  in 
  a 
  sharp 
  leaf- 
  

   less 
  point. 
  

  

  The 
  leaves 
  are 
  alternate 
  and 
  simple 
  but 
  generally 
  more 
  or 
  less 
  

   distinctly 
  lobed 
  and 
  serrated 
  on 
  the 
  margin. 
  Those 
  of 
  young 
  and 
  

   vigorous 
  shoots 
  often 
  differ 
  from 
  others 
  on 
  the 
  same 
  tree 
  in 
  size, 
  

   shape 
  and 
  lobing. 
  The 
  teeth 
  of 
  the 
  margin 
  are 
  nearly 
  always 
  

   tipped 
  with 
  glands 
  which 
  may 
  vary 
  in 
  color 
  in 
  different 
  species. 
  

   The 
  teeth 
  themselves 
  vary 
  according 
  to 
  the 
  species. 
  They 
  may 
  be 
  

   short 
  or 
  long, 
  narrow 
  or 
  broad, 
  blunt 
  or 
  sharp 
  pointed, 
  straight 
  

   or 
  incurved. 
  The 
  surface 
  of 
  the 
  leaf 
  blades 
  may 
  be 
  smooth, 
  

   pubescent 
  or 
  scabrous. 
  In 
  many 
  species 
  the 
  upper 
  surface 
  of 
  the 
  

   vouno' 
  leaves 
  mav 
  be 
  coated 
  with 
  deciduous 
  hairs 
  which 
  soon 
  dis- 
  

   appear 
  leaving 
  the 
  surface 
  of 
  the 
  mature 
  leaves 
  glabrous. 
  The 
  

   lower 
  surface 
  is 
  generally 
  paler 
  than 
  the 
  upper. 
  In 
  some 
  species 
  

   the 
  young 
  unfolding 
  leaves 
  are 
  tinged 
  with 
  brownish 
  red 
  or 
  bronze 
  

   red 
  but 
  they 
  become 
  green 
  with 
  advancing 
  age. 
  The 
  leaves 
  are 
  

   normally 
  petiolate 
  and 
  stipulate 
  but 
  the 
  stipules 
  soon 
  disappear 
  

   and 
  in 
  some 
  species 
  the 
  petioles 
  are 
  short 
  and 
  so 
  widely 
  margined 
  

   by 
  the 
  decurrent 
  leaf 
  blades 
  that 
  the 
  leaves 
  appear 
  to 
  be 
  sessile. 
  

   The 
  petioles 
  are 
  often 
  furnished 
  with 
  a 
  few 
  glands 
  which 
  may 
  be 
  

   either 
  sessile 
  or 
  stalked. 
  They 
  are 
  often 
  more 
  highly 
  colored 
  

   when 
  old 
  than 
  when 
  young, 
  and 
  are 
  apt 
  to 
  be 
  shorter 
  on 
  vigorous 
  

   shoots 
  than 
  on 
  fruiting 
  or 
  lateral 
  branches. 
  In 
  general 
  outline 
  

   the 
  leaf 
  blades 
  may 
  vary 
  in 
  different 
  species 
  from 
  oblanceolate 
  or 
  

   spatulate 
  to 
  obovate, 
  ovate, 
  oblong 
  ovate, 
  elliptic, 
  oval 
  or 
  orbicu- 
  

   lar. 
  

  

  The 
  buds 
  are 
  compact 
  and 
  globular 
  with 
  very 
  broad 
  blunt 
  

   scales. 
  In 
  some 
  species 
  they 
  are 
  covered 
  with 
  a 
  varnish 
  which 
  

   becomes 
  sticky 
  in 
  warm 
  weather. 
  When 
  they 
  burst 
  in 
  spring 
  the 
  

   inner 
  scales 
  enlarge 
  rapidly, 
  become 
  elongated 
  and 
  assume 
  pink
