  Artocarpus 
  dubia, 
  «. 
  5/>., 
  Plate 
  38, 
  fig. 
  3. 
  

  

  Leaf 
  irregularly 
  three-lobed, 
  lower 
  lobes 
  short, 
  obtuse, 
  ascending, 
  middle 
  

   lobe 
  broadest 
  near 
  the 
  middle 
  and 
  tapering 
  to 
  a 
  pointed 
  apex, 
  base 
  wedge- 
  

   shaped 
  ; 
  secondary 
  nervation 
  pinnate 
  throughout 
  and 
  camptodrome. 
  

  

  It 
  is 
  possible 
  that 
  this 
  may 
  be 
  merely 
  a 
  young 
  or 
  small 
  leaf 
  of 
  

   A. 
  lessigiayia 
  (I^esq.) 
  Ku., 
  but 
  it 
  appears 
  to 
  be 
  so 
  distinct 
  and 
  is 
  

   so 
  well 
  defined 
  that 
  I 
  have 
  thought 
  it 
  best 
  to 
  describe 
  it 
  as 
  a 
  new 
  

   species.

   Our 
  specimen 
  is 
  too 
  imperfect 
  for 
  satisfactory^ 
  identification 
  

  

  and 
  I 
  have 
  therefore 
  only 
  referred 
  it 
  provisionally 
  to 
  this 
  species. 
  

  

  It 
  agrees 
  very 
  closely 
  with 
  Lesquereux,

  quoted.

  Ficus

  Leaf 
  about 
  3^ 
  in. 
  long 
  by 
  3^^ 
  in. 
  broad 
  across 
  the 
  middle; 
  constricted 
  

   to 
  a 
  blunt 
  (?) 
  apex 
  and 
  wedge-shaped 
  at 
  the 
  base 
  ; 
  margin 
  entire 
  and 
  wavy 
  ; 
  

   three-nerved 
  from 
  the 
  base 
  and 
  with 
  two 
  pairs 
  of 
  prominent 
  sub-opposite 
  

   secondaries 
  above 
  ; 
  midrib 
  strongest, 
  basal 
  nerves 
  branched 
  from 
  the 
  lower 
  

   side 
  ; 
  all 
  nervation 
  finally 
  thinning 
  out 
  and 
  inosculating 
  near 
  the 
  margin, 
  

   tertiary 
  nervation 
  mainly 
  at 
  right 
  angles 
  to 
  the 
  primaries, 
  secondaries, 
  and 
  

   sub-secondaries, 
  but 
  broken 
  in 
  places 
  by 
  finer 
  cross 
  reticulations. 
  

  

  It 
  is 
  with 
  hesitation 
  that 
  I 
  have 
  finally 
  decided 
  to 
  place 
  this 
  

   leaf 
  in 
  the 
  genus 
  Ficus. 
  In 
  some 
  respects 
  it 
  suggests 
  Aralia, 
  

   and 
  in 
  others 
  Hedera 
  and 
  in 
  general 
  appearance 
  is 
  not 
  unlike
