 O u r  figure No.  1  was drawn from  a  specimen  received  by  
 Mr. Woodward frorp Devonshire.  The leafy  bottom  part of  
 a younger plant f .  2, is the Mediterranean  specimen, mentioned  
 inTr.  of  L. Soc.  v.  3,  127 ;  and f .   3  is  the fructification  
 in a very  perfect  state,  sent by Mr. W. Borrer from  Sussex in  
 June  1804.  There can be no  doubt of the Linnsean specimen,  
 gathered  by Loefling  in  the  British  seas,  being  tbe  same,  
 though  it wants  the  bottom leaves,  nor  do  we  perceive why  
 our learned  friends Mr. Turner and Mr. Wigg  found  any uncertainty  
 about  i t ;  but however that may be,  it is  the original  
 and only certain  authority for this  species.  It is impossible to  
 account for Linnaeus’s  subsequent  misquotation  of  Gmelin’s  
 capensis,  Mant.  2.  508,  which  is  totally  different.—The  
 present  belongs  to the same  tribe with  F.  fibrosus,  t.  1909,  
 and'agrees with  that in  colour,  Frond  12 or  18  inches  long,  
 slender,  compressed, often  rough  like  a  file  at  the  base,  and  
 furnished in  that  part when young, with  opposite or  alternate,  
 two-ranked,  deeply  pinnatifid,  flat,  entire  leaflets,  (for  so, if  
 the whole be  a frond, as analogy shows,  we must  call  them):  
 doubly  pinnate upwards,  the  pinnae repeatedly and  alternately  
 forked,  thread-shaped,  spreading;  the  upper  ones  bearing  
 small, elliptical,  solitary,  innate  vesicles,  each  crowned  with  
 several  cloven  leaflets,  in the blunter and more dilated  of which  
 numerous  seeds  are  lodged  in  oblong clefts.  We  refer the  
 reader  to F.  discors,  t,  2131,  for  further  remarks  relative  to  
 be plant before us.
