  one 
  is 
  indigenous 
  to 
  New 
  Zealand, 
  which, 
  however, 
  possesses 
  two 
  endemic 
  

   species, 
  one 
  representing 
  the 
  nuciimentaceons 
  section 
  of 
  the 
  order, 
  the 
  other 
  

   tlie 
  fohiculaceoiis 
  section 
  ; 
  the 
  former 
  belongs 
  to 
  Fersoonia, 
  a 
  genus 
  largely 
  

   developed 
  in 
  Australia, 
  but 
  not 
  known 
  elsewhere 
  ; 
  the 
  latter 
  to 
  Knightia, 
  of 
  

   which 
  one 
  other 
  species 
  is 
  known 
  in 
  New 
  Caledonia. 
  The 
  large 
  genus 
  

   Pimelea, 
  restricted 
  to 
  New 
  Zealand 
  and 
  Australia, 
  comprises 
  nearly 
  seventy 
  

   species 
  in 
  the 
  latter 
  country 
  and 
  ten 
  in 
  the 
  former, 
  but 
  except 
  P. 
  longifoUa, 
  

   which 
  extends 
  from 
  this 
  colony 
  to 
  Lord 
  Howe's 
  Island 
  on 
  the 
  Australian 
  

   coast, 
  no 
  species 
  is 
  common 
  to 
  both 
  floras. 
  

  

  Fagus, 
  which 
  forms 
  so 
  large 
  a 
  part 
  of 
  the 
  mountain 
  forests 
  in 
  New 
  

   Zealand, 
  is 
  represented 
  in 
  Australia 
  by 
  three 
  s^Decies, 
  all 
  of 
  which 
  are 
  

   endemic. 
  

  

  In 
  Coniferas 
  there 
  is 
  no 
  species 
  common 
  to 
  both 
  countries 
  ; 
  the 
  common 
  

   genera 
  Damviara, 
  Podocarpits, 
  Phyllocladus, 
  and 
  Dacrydium 
  ; 
  except 
  Podocar- 
  

   pus, 
  each 
  is 
  represented 
  by 
  a 
  single 
  genus 
  in 
  Australia, 
  but 
  Phyllocladus 
  and 
  

   Dacrydium 
  are 
  especially 
  characteristic 
  of 
  New 
  Zealand, 
  the 
  first 
  having 
  

   three 
  species, 
  one 
  or 
  other 
  of 
  which 
  is 
  found 
  scattered 
  throughout 
  the 
  colony 
  

   except 
  in 
  the 
  driest 
  districts 
  ; 
  the 
  other 
  contains 
  seven 
  species, 
  some 
  of 
  

   which 
  occur 
  in 
  all 
  districts. 
  In 
  this, 
  as 
  in 
  many 
  similar 
  cases, 
  the 
  Australian 
  

   flora 
  has 
  been 
  influenced 
  by 
  that 
  of 
  New 
  Zealand 
  rather 
  than 
  the 
  reverse. 
  

  

  A 
  much 
  larger 
  proportion 
  of 
  Monocotyledons 
  is 
  common 
  to 
  both 
  countries, 
  

   chiefly 
  owing 
  to 
  the 
  wide 
  distribution 
  of 
  many 
  species 
  of 
  Cyperacese 
  and 
  

   Gramine^. 
  

  

  In 
  Orchidaceffi 
  there 
  is 
  a 
  close 
  generic 
  relationship, 
  no 
  fewer 
  than 
  sixteen 
  

   genera 
  being 
  common 
  to 
  both 
  countries, 
  but 
  not 
  more 
  than 
  six 
  species, 
  two 
  

   alone 
  of 
  which 
  are 
  found 
  elsewhere 
  ; 
  the 
  restricted 
  distribution 
  of 
  the 
  species 
  

   of 
  this 
  order 
  is 
  strongly 
  marked 
  all 
  over 
  the 
  world. 
  

  

  Astelia, 
  a 
  liliaceous 
  genus 
  largely 
  developed 
  in 
  New 
  Zealand, 
  is 
  repre- 
  

   sented 
  in 
  Australia 
  by 
  a 
  single 
  endemic 
  species. 
  Juncese 
  has 
  eight 
  species 
  

   common 
  to 
  both 
  countries, 
  six 
  of 
  which 
  are 
  found 
  nowhere 
  else. 
  

  

  Twelve 
  genera 
  of 
  Cyperace^e, 
  and 
  thirty-two 
  species, 
  are 
  common 
  to 
  both 
  

   floras 
  ; 
  many 
  of 
  the 
  species 
  exhibit 
  a 
  wide 
  distribution, 
  and 
  not 
  more 
  than 
  

   twelve 
  are 
  restricted 
  to 
  Australia 
  and 
  New 
  Zealand. 
  

  

  In 
  Gramine^e 
  the 
  relationship 
  is 
  still 
  more 
  strongly 
  marked, 
  more 
  than 
  

   half 
  the 
  New 
  Zealand 
  species, 
  and 
  twenty-five 
  genera 
  out 
  of 
  twenty-seven, 
  

   being 
  common 
  to 
  both 
  countries 
  ; 
  only 
  ten 
  of 
  the 
  species 
  are 
  restricted 
  to 
  

   these 
  countries, 
  many 
  of 
  them 
  having 
  a 
  wide 
  distribution. 
  

  

  In 
  ferns 
  and 
  allied 
  plants, 
  the 
  proportion 
  of 
  species 
  common 
  to 
  both 
  

   countries 
  is 
  still 
  larger. 
  Austraha 
  exhibits 
  two 
  hundred 
  and 
  thirty-two 
  

   species, 
  comprised 
  under 
  forty-seven 
  genera; 
  New 
  Zealand 
  has 
  thu'ty- 
  

   nine 
  genera 
  and 
  one 
  hundred 
  and 
  fifty-three 
  species.
