 affections,  but  unsafe  as  a  medicine.  Its  acrid  quality produces  
 very  unpleasant  sensations  in  the  mouth.  Bigelow’s  £t Medical  
 Botany.” 
 Calla.  L.  19.  12. 
 Spathe  flattish  ;  spadix  covered  with  flowers ;  berry  many-  
 seeded.  Pliny named  some plant  Calla,  perhaps  of  this  family,  
 probably from  its  beauty. 
 C.  palustris.  L.  Water  Arum.  A  singular  and  rather  
 beautiful  plant.  Its  creeping  roots,  scarcely  passing  under  the  
 surface  of  the  sphagnous  swamps  in  which  it  delights,  send  up  
 foot-stalks  bearing  a single mass  of white  flowers,  which  are  surrounded  
 in  their  rudimentary  state  with  a  strong  envelope  or  
 spathe^of  a fine  white  color,  and  soft  texture  on the  inside,  and  
 forming a protection to the young flowers.  Roots  acrid ;  but they  
 lose  this  property  by  drying  or  boiling,  so  that  they were  used,  
 according to  Linnaeus,  by the  Laplanders  to form  a sort of bread.  
 Indigenous  also  to  the  northern parts  of Europe. 
 C.  JEthiopica.  W.  A  larger and taller plant, with its  glossy  
 and  shining  deep-green  leaves,  raised with  great  care  in  greenhouses  
 and parlours,  will  recall  the  thoughts  to  the  other humble  
 native  of  our  country,  and  of  Europe.  The  exotic  is  from  the  
 Cape  of  Good Hope. 
 A corus.  L.  6.  1. 
 Supposed  to  relieve  diseases  of  the  eye,  and  hence its name  
 from the Greek.  Spadix  cylindric,  covered with  flowers  ;  perianth  
 6-petalled,  naked ;  ovary  1. 
 A.  calamus.  L.  Sweet Flag.  The  meaning  of  Calamus  is  
 a reed, and the name  is  given to  this  plant from its  resemblance to  
 the genus Calamus.  Common  beside  slow  streams  and  in  wet  
 grounds:  Its  sword-shaped  leaves  ;  its  solitary  flower-stem  or 
 spadix, projecting from a leaf, and aromatic and pleasant to the taste  
 when  young ;  its  zigzag roots  with their numerous fibres, aromatic 
 and  stimulant,  are  well  known.  The  root is  often  used  as  a stomachic, 
   and  as  a remedy  for the  cholic.  The  flavor is  improved  
 by  drying.  Indigenous  to  Europe  and  Asia  as  well  as  North  
 America.  It  was  said  by  Linnaeus  to  be  the  “ only  aromatic  
 plant  of  northern  climates.” 
 ORDER  258.  FLUV IA LE S. 
 Stamens  and  pistils  in the  same  or  different  flowers ;  perianth  
 of  2  or 4  divisions,  sometimes  falls  off  early  in  the  flowering  ;  
 ovary  superior, with the  stamens  rising  from  under i t ;  fruit  dry,  
 4-celled,  1-seeded;  aquatics, with  flowers  small  and  unattractive ;  
 more  resemble  flowerless  plants  than  any yet  mentioned ;  leaves'  
 very  cellular,  with  parallel veins.  The  order  is  named  from the  
 habitation  of  the plants. 
 Najas.  L.  19.  1.  Fluvialis,  Persoon. 
 Perianth wanting ;  flowers  with  stamens, and  others  with pistils  
 on the same plant;  style  1. 
 JST.  Canadensis.  Mx.  Water  Nymph.  The  popular  name  
 might lead  one  to  expect a plant  of some  beauty.  It is  a slender,  
 flexible,  rather  erect,  and  immersed  aquatic,  filiform  or  threadlike, 
   not  very  common;  in  stagnant  waters  ;  Amherst,  Stock-  
 bridge.  Caulinia Jlexilis, W. 
 Z ostera.  L.,  19.  1. 
 Z.  marina.  L.  Grass  Wrack.  Stem  round  and  flexuous,  
 with  roots  at the  joints,  and  with long linear leaves  ;  grows  in  the  
 muddy waters of the  sea-coast,  sometimes called  Eel-grass.  “  A  
 common material for packing, and for stuffing cottagers’  cushions.”  
 Lind. 
 Chara.  L .  19.  l. 
 Origin  of  this  name  unknown,  as  well  as  the  plant  to  which  
 Caesar  applied  it.  Loudon.  The  plants  have  a  rather  beautiful  
 appearance  as  they wave  about under water. 
 Perianth none, flowers  very minute ;  anther sessile and  globose,
