 Hab.  Canada to the West Indies,  and Ecuador ; Cape Colony.—A.  ebenoides,  Scott,  of  
 which  a single  root was found  on  tbe  banks  of  the Schuykill above Philadelphia,  looks  
 most like this ;  but  tbe  pinnæ  are  not  out  down  to  the  rachis,  and  the frond  has an  
 elongated point which is only sinuated with a single row of sori on each  side.  Probably,  
 as  suggested  by  Professor  Eaton,  this  is  A . Hendersoni of Honlston, figured by Lowe,
