  The 
  sorus 
  characters 
  of 
  this 
  species 
  and 
  of 
  C. 
  straminea 
  have 
  been 
  discussed 
  

   under 
  the 
  latter 
  species. 
  Since 
  C. 
  blepharodes 
  is 
  somewhat 
  intermediate 
  in 
  

   sorus 
  structure, 
  C. 
  duhia 
  may 
  best 
  be 
  regarded 
  as 
  the 
  type 
  merely 
  of 
  a 
  new 
  

   subgenus, 
  Calochlaena, 
  the 
  name 
  being 
  chosen 
  in 
  allusion 
  to 
  the 
  distinctive 
  

   character 
  of 
  the 
  delicate 
  true 
  indusium. 
  

  

  A 
  good 
  deal 
  of 
  doubt 
  exists 
  as 
  to 
  the 
  proper 
  reference 
  of 
  Balantium 
  hrown- 
  

   ianum. 
  This 
  name 
  was 
  proposed 
  in 
  1836 
  by 
  Presl, 
  who 
  cited 
  as 
  synonyms 
  

   Davallia 
  duhia 
  R. 
  Br. 
  and 
  Dicksonia 
  fallax 
  Kaulf., 
  and 
  published 
  an 
  illustra- 
  

   tion 
  (pi. 
  5, 
  /.

  ). 
  The 
  name 
  Davallia 
  fallax 
  had 
  been 
  given 
  by 
  Kaulf 
  uss 
  to 
  

   an 
  Australian 
  plant 
  distributed 
  by 
  Sieber. 
  Luerssen, 
  who 
  has 
  examined 
  this, 
  

   refers 
  it 
  to 
  Dicksonia 
  duhia; 
  but 
  the 
  highly 
  conventional 
  figure 
  shows 
  sori 
  

   like 
  those 
  of 
  C. 
  straminea, 
  as 
  Hooker 
  has 
  remarked, 
  and 
  bearing 
  very 
  little 
  

   likeness 
  to 
  those 
  of 
  C. 
  duhia, 
  whether 
  or 
  not 
  it 
  was 
  drawn 
  from 
  Australian 
  

   material. 
  Brackenridge 
  has 
  pointed 
  out 
  the 
  same 
  discrepancy, 
  and 
  until 
  

   the 
  Sieber 
  plant 
  has 
  been 
  re-examined 
  critically 
  the 
  correct 
  disposition 
  of 
  

   Balantium 
  hrovunianum 
  must 
  remain 
  doubtful.

  or 
  more, 
  the

  about 
  one-third

  long 
  

   as 
  the 
  blade, 
  sulcate, 
  ochraceous 
  from 
  a

  base 
  ; 
  blade 
  tripinnate, 
  the

  30 
  cm. 
  long, 
  5

   deltoid-oblong, 
  the 
  rachis 
  firm, 
  brownish-stramineous; 
  pinnules 
  distant, 
  

   alternate 
  to 
  subopposite, 
  oblique, 
  deltoid-oblong, 
  acuminate; 
  segments 
  

   10 
  to 
  15 
  pairs, 
  slightly 
  oblique, 
  linear 
  or 
  linear-oblong, 
  cuneate 
  at 
  the 
  inequi- 
  

   lateral 
  base, 
  abruptly 
  acuminate, 
  distant, 
  faintly 
  connected 
  along 
  the 
  ven- 
  

   tral 
  groove 
  of 
  the 
  tertiary 
  rachis, 
  deeply 
  lobed 
  throughout; 
  lobes 
  of 
  the 
  

   larger 
  segments 
  5 
  to 
  7 
  pairs, 
  mostly 
  with 
  2 
  lobules 
  or 
  crenations 
  on 
  the 
  distal 
  

   side, 
  the 
  apical 
  one 
  sterile 
  and 
  curved 
  upward, 
  the 
  other 
  broader 
  and 
  soriferous 
  ; 
  

   sorus 
  about 
  1 
  mm. 
  in

  fertile 
  lobule 
  invariably 
  concave, 
  but 
  not 
  

   saccate; 
  true 
  indusium 
  ample, 
  delicately 
  membranous, 
  long-ciliate, 
  born 
  

   upon 
  a 
  narrowly 
  oblong, 
  transverse 
  receptacle, 
  early 
  thrust 
  backward 
  against 
  

   the 
  leaf 
  surface 
  and 
  exposing 
  the 
  numerous 
  sporangia; 
  paraphyses 
  many, 
  

   slender, 
  brown;

  surface 
  of 
  blade

  ex- 
  

   tending 
  abundantly 
  to

  surface 
  slightly 
  hirsute, 
  glabrescent.

  1,094,080, 
  collected 
  at 
  "Lomo- 
  

   Lomo" 
  or 
  "Somu-Somu," 
  Fiji 
  Islands, 
  by 
  the 
  Wilkes 
  Expedition 
  (1838-42). 
  

   There 
  is 
  a 
  second, 
  smaller 
  specimen 
  of 
  the 
  same 
  collection. 
  

  

  This 
  is 
  the 
  plant 
  which 
  Brackenridge, 
  having 
  mistakenly 
  redescribed 
  the 
  

   Dicksonia 
  straminea 
  of 
  La 
  Billardiere 
  as 
  a 
  new 
  species 
  of 
  Dicksonia 
  (D. 
  

   torreyana 
  Brack.), 
  listed 
  as 
  Sitolohium 
  stramineum. 
  He 
  properly 
  compares 
  it 
  

   with 
  Sitolohium 
  duhium 
  Brack. 
  (Culcita 
  duhia) 
  and 
  notes 
  several 
  points 
  of 
  

   distinction. 
  

  

  Culcita 
  hlepharodes 
  belongs 
  to 
  the 
  subgenus 
  Calochlaena, 
  and 
  is 
  closely
