  long 
  ; 
  calix 
  as 
  in 
  the 
  preceding 
  ; 
  segments 
  of 
  the 
  corolla 
  the 
  same 
  colour, 
  

   but 
  shorter, 
  scarcely 
  covering 
  the 
  brown 
  lepanthium, 
  of 
  which 
  the 
  seg- 
  

   ments 
  are 
  very 
  patulous 
  and 
  incurved, 
  and 
  exceed 
  the 
  antheridium 
  in 
  

   length 
  ; 
  the 
  chasms 
  of 
  the 
  antheridium 
  are 
  remarkably 
  salient, 
  angular 
  

   and 
  crustaceous 
  ; 
  with 
  the 
  follicles 
  I 
  am 
  unacquainted.

  — 
  Obs. 
  This 
  genus, 
  

   which 
  will 
  probably 
  prove 
  abundant 
  in 
  species, 
  is 
  very 
  nearly 
  allied 
  to 
  

   the 
  Calotropis 
  of 
  R. 
  Brown, 
  but 
  differs 
  essentially 
  in 
  the 
  insertion 
  of 
  

   the 
  lepanthium 
  and 
  the 
  form 
  and 
  character 
  of 
  its 
  segments.
