   flexuous

  when

  up 
  to 
  5 
  mm. 
  long, 
  from 
  an 
  ovate 
  

   base 
  about 
  1.5 
  mm. 
  long 
  with 
  margins 
  finely 
  serrulate 
  in 
  upper 
  

   half 
  and 
  mostly 
  entire

  narrowed 
  to 
  a 
  point 
  two 
  to 
  three 
  

   and 
  one 
  half 
  times 
  longer 
  with 
  thickened, 
  somewhat 
  doubly 
  

   serrulate 
  border 
  extending 
  from 
  basal 
  part 
  to 
  a 
  little 
  below 
  the 
  

   mostly 
  blunt 
  and 
  serrulate 
  apex; 
  leaf-surface

  highly 
  

   mamillose, 
  on 
  under 
  side 
  nearly 
  smooth

  costa 
  vanishing 
  just 
  below

   often 
  bearing

  cross-sections 
  

   near

  leaf 
  show 
  eight

  a

  band 
  of 
  six 
  to 
  nine

   enclosing 
  one

  Type 
  locality: 
  Panama 
  near 
  David. 
  

  

  Distribution: 
  known 
  only 
  from 
  the 
  type 
  locality. 
  

  

  This 
  species 
  is 
  much 
  like 
  C. 
  nicaraguense 
  but 
  has 
  rather 
  longer 
  

   leaves, 
  the 
  basal 
  margin 
  more 
  entire 
  and 
  without 
  teniolae; 
  also 
  

   the 
  thickened 
  border 
  contains 
  a 
  few 
  stereid 
  cells 
  that 
  seem 
  to 
  be 
  

   wanting 
  in 
  C. 
  nicaraguense, 
  and 
  the 
  costa 
  is 
  mostly 
  smooth 
  on 
  

   upper 
  side.
