  derris

  is, 
  perhaps, 
  tlio 
  most 
  abundant 
  ; 
  Bracophyllnm 
  squar- 
  

   rosum, 
  Lencopnrjon 
  fasciciilatam, 
  L. 
  frazeri, 
  Cyathodcs 
  acerosa, 
  GauUherla 
  

   antipoda, 
  Coriarla 
  ruscifoUa, 
  etc., 
  are 
  common. 
  The 
  more 
  frequent 
  grasses 
  

   and 
  herbaceous 
  plants 
  are 
  Sporobolns 
  clongatus, 
  Agrostis 
  ainula, 
  A. 
  quadriset/i, 
  

   Triticain 
  nuiltifloruin, 
  Poa

  Dlchelachne 
  crinita, 
  Microlama 
  stlpoides. 
  

   Glyceria

  was 
  collected 
  in 
  a 
  single 
  locality 
  on 
  the 
  coast. 
  Geranium

   etc. 
  In 
  most 
  places 
  Cladium, 
  sinclairii, 
  C. 
  gunnii, 
  Schuenus 
  tendo, 
  S. 
  tcnax, 
  

   etc., 
  with 
  a 
  few 
  orchids, 
  of 
  which 
  the 
  most 
  frequent 
  were 
  Microtis 
  porrifulia, 
  

   Thelgmitra 
  longifolia, 
  and 
  Orthoccras 
  solandri. 
  Phormium 
  tcnax, 
  with 
  several 
  

   species 
  of 
  Juncus, 
  Carex, 
  Gahnia 
  and 
  other 
  sedges, 
  occurred 
  in 
  marshy 
  

   places, 
  especially 
  on 
  the 
  borders 
  of 
  forests, 
  but, 
  as 
  a 
  rule, 
  paludal 
  plants 
  

   were 
  poorly 
  represented. 
  

  

  Arborescent 
  ferns 
  are 
  represented 
  by 
  Cyathea 
  medullaris, 
  C. 
  dealbata, 
  

   Dicksonia 
  squarrosa, 
  and 
  verj' 
  rarely 
  by 
  Hemitelia 
  smithii 
  ; 
  none 
  of 
  the 
  rarer 
  

   kinds 
  were 
  observed. 
  The 
  ferns 
  and 
  allied 
  plants 
  generally 
  were 
  remark- 
  

   ably 
  few 
  in 
  number 
  ; 
  besides 
  the 
  tree 
  ferns, 
  the 
  most 
  striking 
  are 
  Lomaria 
  

   fraseri, 
  and 
  Lygodium 
  arliculatuni: 
  

  

  I 
  have 
  already 
  mentioned 
  the 
  general 
  resemblance 
  between 
  the 
  chief 
  

   physical 
  features 
  of 
  the 
  Kawau 
  and 
  Waiheke. 
  Although 
  the 
  total 
  number 
  

   of 
  ferns 
  on 
  the 
  latter 
  island 
  is 
  greatly 
  below 
  that 
  of 
  the 
  Kawau, 
  the 
  resem- 
  

   blance 
  between 
  the 
  Phtenogamic 
  portion 
  of 
  the 
  flora''' 
  of 
  both 
  is 
  remarkably 
  

   close. 
  I 
  can 
  only 
  enumerate 
  three 
  plants 
  as 
  occurring 
  on 
  Waiheke, 
  which 
  

   are 
  not 
  also 
  found 
  on 
  Kawau 
  : 
  they 
  are 
  Hymenanthera 
  tasmanica, 
  Pimelca 
  

   arenaria, 
  and 
  Melicytus 
  micranthus 
  ; 
  the 
  first 
  and 
  second 
  of 
  these 
  are 
  

   extremely 
  rare, 
  the 
  third 
  occurs 
  in 
  several 
  localities, 
  and 
  in 
  all 
  probability 
  

   is 
  to 
  be 
  found 
  on 
  Kawau, 
  although 
  not 
  observed 
  either 
  by 
  Mr. 
  Buchanan 
  or 
  

   myself. 
  

  

  The 
  kauri 
  and 
  tooth-leaved 
  beech, 
  both 
  of 
  which 
  are 
  rare 
  on 
  Kawau, 
  

   occur 
  or 
  rather 
  have 
  occurred 
  on 
  Waiheke 
  in 
  considerable 
  quantity. 
  

   Coprosma 
  arborea 
  is 
  also 
  more 
  plentiful 
  on 
  the 
  latter 
  island 
  than 
  the 
  former, 
  

   and 
  the 
  same 
  remark 
  applies 
  to 
  Mctrosideros 
  robusta, 
  of 
  which 
  only 
  a 
  single 
  

   specimen 
  is 
  known 
  in 
  Kawau. 
  The 
  large 
  tea-tree, 
  although 
  plentiful 
  on 
  

   that 
  island, 
  never 
  occurred 
  in 
  such 
  great 
  abundance 
  as 
  on 
  Waiheke. 
  On 
  

   the 
  other 
  hand, 
  one 
  of 
  the 
  most 
  characteristic 
  plants 
  of 
  the 
  Kawau 
  flora, 
  

  

  * 
  Of 
  course 
  excludiug 
  numerous 
  sioecies, 
  such 
  as 
  Gnaphuliuiii 
  filicaule, 
  Juncus 
  novm- 
  

   zealandia, 
  Uncinia 
  rubra, 
  Eryvgium 
  vesicidosum, 
  etc., 
  etc., 
  erroneously 
  recorded 
  as 
  

   indigenous 
  on 
  Kawau.
