 Arum.  Raii Syn.  266. 
 A t   the  first approach of spring the verdant  shining leaves  of  
 the Arum are seen  shooting up abundantly wherever any brushwood  
 protects  them  from  the tread of men or of  cattle.  In  
 May the very extraordinary flowers  appear.  In autumn,  after  
 both flowers  and leaves have vanished,  a spike of scarlet berries,  
 on  a  simple stalk,  are  all  that  remains,  and  few  persons,  as  
 Mr.  Curtis  observes,  are aware of the plant to which they owe  
 their origin. 
 The  root is perennial, tuberous,  abounding with  a  mucilage  
 which  affords  starch,  and with a peculiar hot acrimony, lost in  
 drying;  so  that  the  powder  of  Arum  kept  in  the  shops can  
 only be of  use in consequence of what is compounded with it.  
 Leaves  radical,  erect,  halberd-shaped,  entire,  mostly  spotted  
 with black.  Stalk radical,  simple.  Sheath erect,  large,  acute,  
 hollow,  pale  green,  sometimes  spotted,  enfolding  the  spadix  
 or pillar of fructification,  whose summit is cylindrical, obtuse,  
 purplish,  spongy  within,  supposed  to  perform  the  functions  
 of  a  corolla,  or • something  analogous  to  respiration  :  below  
 this,  after a naked  contracted  space,  are several  rows of glands  
 tipped with  filaments;  then  a dense band  of  purple sessile an-  
 therce,  below which  stand  numerous germens.  This  position  
 of  the flowers,  exactly analogous  to  that  of  the  most genuine  
 monoecious plants,  has  induced  us  to  remove  this  genus  to  
 Monoecia.  No  principle can  reconcile  it  to the Gynandria.
