  catkins 
  are 
  closely 
  appressecl, 
  and 
  ascending, 
  but 
  when 
  the 
  sporangia 
  dis- 
  

   charge 
  their 
  contents 
  the 
  tips 
  of 
  the 
  scales 
  become 
  patent 
  or 
  even 
  reflesed. 
  

   The 
  points 
  of 
  the 
  young 
  shoots 
  are 
  often 
  of 
  a 
  reddish 
  colour, 
  and 
  when 
  

   growing 
  in 
  exposed 
  situations 
  the 
  leaves 
  become 
  harsh 
  and 
  pungent. 
  

  

  Not 
  unfrequently 
  two 
  spikes 
  are 
  produced 
  from 
  the 
  apex 
  of 
  a 
  branch, 
  

   and 
  rarely 
  the 
  fertile 
  branch 
  is 
  overtopped 
  by 
  a 
  luxuriant 
  " 
  usurping 
  shoot," 
  

   so 
  that 
  the 
  spike 
  appears 
  to 
  be 
  lateral, 
  showing 
  its 
  close 
  af&nity 
  with 
  

   L. 
  laterale, 
  which 
  is 
  still 
  further 
  strengthened 
  by 
  the 
  fact 
  that 
  in 
  that 
  species 
  

   the 
  spikes 
  are 
  not 
  invariably 
  sessile, 
  but 
  occasionally 
  are 
  developed 
  on 
  very 
  

   short 
  leafy 
  peduncles. 
  

  

  It 
  is 
  worthy 
  of 
  note 
  that 
  in.L. 
  laterale 
  the 
  spikes 
  are 
  frequently 
  confined 
  

   to 
  one 
  side 
  of 
  the 
  stem.

  Our 
  ]3lant 
  has 
  affinities 
  also 
  with 
  L. 
  clavatum, 
  <p 
  magellanicum. 
  

  

  L. 
  laterale 
  and 
  L. 
  divulsum 
  are 
  considered 
  distinct 
  by 
  Bentham, 
  in 
  Flora 
  

   Australiensis 
  [Vol. 
  VII., 
  p. 
  675.] 
  In 
  New 
  Zealand 
  the 
  latter 
  form 
  is 
  not 
  

   confined 
  to 
  alpine 
  districts, 
  but 
  occasionally 
  occurs 
  in 
  peaty 
  bogs, 
  from 
  the 
  

   sea 
  level 
  upwards, 
  and 
  notwithstanding 
  its 
  rigid 
  appearance 
  passes 
  by 
  

   insensible 
  gradations 
  into 
  the 
  typical 
  form 
  of 
  L. 
  laterale.
