At  this  point  of  the  Vegetable  Kingdom  we  find  a  most  curious  assem-
blage, which,  with  many  of  the  peculiarities  of  Endogens,  seems  to  be  an
intermediate  form  of  organisation  between  them  and  Thallogens.  They
have  no  relation  to  Acrogens,  although  they  follow  at  this  place,  but  they
agree  with  Endogens  in  the  presence  of  sexes,  and  sometimes  in  the  ternary
structure  of  their  flower  ;  they  have,  however,  scarcely  any  spiral  vessels,
and  their  seeds  appear,  as  far  as  they  have  been  examined,  either,  as  some
say,  to  want  the  cotyledons  and  axis  of  other  flowering  plants,  or  to  lose
themselves  in  a  mass  of  pulp,  from  which  they  are  almost  undistinguishable.
In  their  amorphous  succulent  texture,  in  their  colour,  often  in  their  putrid
odour  when  decaying,  in  the  formation  of  a  mycelium  or  spawn,  which  is
evident  in  Helosis,  and  is  with  good  reason  suspected  to  exist  in  others,
and  in  their  parasitical  habits,  these  plants  resemble  Fungals,  while  in  their
flowers  and  sexes  they  accord  with  Arumworts,  or  similar  Endogens.
