  following  arrangement  recognizes  four  classes:  --  I. 
  {{Pteridophyta},  or  {Vascular  Acrogens}.}  These  include 
  Ferns,  {Equiseta}  or  Scouring  rushes,  {Lycopodiace[ae]} 
  or  Club  mosses,  {Selaginelle[ae]},  and  several  other 
  smaller  orders  Here  belonged  also  the  extinct  coal 
  plants  called  {Lepidodendron},  {Sigillaria},  and 
  {Calamites}.  II  {{Bryophita},  or  {Cellular  Acrogens}}. 
  These  include  {Musci},  or  Mosses,  {Hepatic[ae]},  or 
  Scale  mosses  and  Liverworts,  and  possibly 
  {Charace[ae]},  the  Stoneworts.  III.  {{Alg[ae]}},  which 
  are  divided  into  {Floride[ae]},  the  Red  Seaweeds,  and 
  the  orders  {Dictyote[ae]},  {O["o]spore[ae]}, 
  {Zo["o]spore[ae]},  {Conjugat[ae]},  {Diatomace[ae]},  and 
  {Cryptophyce[ae]}.  IV  {{Fungi}}.  The  molds,  mildews, 
  mushrooms,  puffballs,  etc.,  which  are  variously  grouped 
  into  several  subclasses  and  many  orders  The  {Lichenes} 
  or  Lichens  are  now  considered  to  be  of  a  mixed  nature, 
  each  plant  partly  a  Fungus  and  partly  an  Alga.
