  at 
  as 
  an 
  immigrant 
  merely. 
  As 
  it 
  is, 
  the 
  retired 
  nature 
  of 
  the 
  locahty, 
  and 
  

   the 
  absence 
  of 
  naturahzed 
  species, 
  save 
  one 
  or 
  two 
  of 
  early 
  introduction 
  and 
  

   wide 
  diffusion, 
  are 
  altogether 
  against 
  this 
  view. 
  I 
  also 
  searched 
  in 
  vain 
  for 
  

   the 
  plant 
  in 
  the 
  immediate 
  vicinity 
  of 
  Nelson, 
  where 
  introduced 
  species 
  are 
  

   so 
  abundant. 
  A 
  further 
  argument 
  in 
  favour 
  of 
  its 
  being 
  indigenous 
  lies 
  in 
  

   the 
  fact 
  that 
  in 
  Australia 
  opposite-leaved 
  forms 
  are 
  decidedly 
  rare, 
  and 
  

   would 
  be 
  by 
  no 
  means 
  hkely 
  to 
  be 
  introduced. 
  

  

  The 
  Maitai 
  Valley 
  appears 
  to 
  be 
  well 
  worthy 
  of 
  a 
  careful 
  exploration. 
  

   Among 
  the 
  plants 
  noticed 
  were 
  Metrosideros 
  colensoi, 
  Myrtus 
  ralpJdi, 
  Myrsine 
  

   montana, 
  and 
  Phyllocladus 
  tricliovianoides. 
  I 
  have 
  been 
  unable 
  to 
  find 
  any 
  

   previous 
  record 
  of 
  the 
  occurrence 
  of 
  these 
  species 
  in 
  the 
  South 
  Island. 
  

   Olearia 
  forsteri 
  occurs 
  in 
  the 
  lower 
  part 
  of 
  the 
  valley. 
  Pittosporum 
  rigidum, 
  

   Myrtus 
  obcordata, 
  Scutellaria 
  novce-zealandice, 
  Pimelea 
  gnidia, 
  are 
  all 
  not 
  

   uncommon. 
  Among 
  ferns 
  Aspidium 
  oculatum 
  and 
  BotrycJdum 
  ternatum 
  

   var. 
  dissectum 
  deserve 
  special 
  mention.

  the

  [Read

  Institute, 
  7th 
  October, 
  1878.] 
  

  

  Since 
  the 
  publication 
  of 
  the 
  "Handbook" 
  several 
  species 
  of 
  Jiincus 
  have 
  

   been 
  added 
  to 
  the 
  New 
  Zealand 
  Flora 
  — 
  two 
  of 
  which, 
  J. 
  glaucus, 
  L., 
  and 
  J. 
  

   lamjjrocarpus, 
  Ehr. 
  — 
  are 
  well-known 
  European 
  plants. 
  I 
  have 
  now 
  to 
  

   record 
  the 
  discovery 
  of 
  Juncus 
  tenuis, 
  Willd., 
  also 
  a 
  common 
  Central 
  

   European 
  and 
  North 
  American 
  species. 
  My 
  specimens 
  were 
  collected 
  in 
  

   January, 
  1875, 
  near 
  Omano, 
  about 
  25 
  miles 
  above 
  Kaihu, 
  on 
  the 
  Northern 
  

   Wairoa 
  Eiver. 
  The 
  plant 
  was 
  abundant 
  in 
  some 
  marshy 
  ground 
  not 
  far 
  

   from 
  the 
  bank 
  of 
  the 
  river 
  ; 
  but 
  curiously 
  enough, 
  during 
  the 
  hurried 
  

   examination 
  I 
  was 
  able 
  to 
  make 
  of 
  the 
  Wairoa 
  district, 
  I 
  did 
  not 
  observe 
  it 
  

   either 
  higher 
  up 
  or 
  lower 
  down 
  the 
  river, 
  although 
  suitable 
  localities 
  are 
  

   sufficiently 
  abundant. 
  

  

  So 
  many 
  European 
  plants 
  are 
  becoming 
  naturalized 
  in 
  the 
  colony 
  that 
  

   additional 
  evidence 
  will 
  be 
  required 
  before 
  Juncus 
  tenuis 
  can 
  be 
  included 
  in 
  

   the 
  list 
  of 
  our 
  indigenous 
  species. 
  It 
  certainly 
  seems 
  improbable 
  that 
  a 
  

   plant 
  with 
  such 
  a 
  wide 
  range 
  in 
  the 
  northern 
  hemisphere 
  should 
  be 
  foimd 
  in 
  

   New 
  Zealand 
  alone 
  in 
  the 
  southern 
  ; 
  but 
  too 
  much 
  stress 
  cannot 
  be 
  placed 
  

   on 
  this 
  argument, 
  as 
  a 
  precisely 
  similar 
  case 
  exists 
  in 
  Carex 
  pyrenaica, 
  which 
  

   no 
  one 
  doubts 
  being 
  a 
  true 
  native 
  of 
  New 
  Zealand. 
  It 
  must 
  be 
  borne 
  in 
  

   mind 
  that 
  our 
  plant 
  is 
  not 
  a 
  native 
  of 
  any 
  part 
  of 
  the 
  British 
  Islands, 
  from 
  

   whence 
  the 
  majority 
  of 
  our 
  naturahzed 
  species 
  are 
  derived 
  ; 
  and 
  the 
  locality
