  The 
  following 
  description 
  of 
  this 
  plant 
  indicates 
  it 
  to 
  be 
  closely 
  allied 
  

   to 
  Pomaderris 
  apetala, 
  LabilL, 
  which 
  is 
  a 
  native 
  of 
  Australia 
  and 
  Tasmania; 
  

   but 
  as 
  it 
  differs 
  in 
  its 
  growing 
  to 
  a 
  much 
  larger 
  size 
  — 
  that 
  species 
  being 
  a 
  

   mere 
  shrub 
  like 
  the 
  kumera-hau 
  (P. 
  ellipticaj 
  of 
  New 
  Zealand, 
  whereas 
  

   the 
  tree 
  now 
  described 
  grows 
  to 
  a 
  height 
  of 
  20 
  feet, 
  with 
  large 
  stems 
  6 
  or 
  6 
  

   inches 
  in 
  diameter 
  — 
  I 
  have 
  thought 
  it 
  better 
  to 
  distinguish 
  it 
  by 
  a 
  specific 
  

   name, 
  and 
  have 
  adopted 
  that 
  by 
  which 
  it 
  is 
  known 
  to 
  the 
  Maoris, 
  

  

  Pomaderris 
  iaimti, 
  n.s.
