n 2fJ I Mr. Brown {Prodr, p. 152) suggested that this plant might probably 



be referred to Lomaria (his Stegania)^ with which indeed it entirely 

 agrees in habit, and other botanists have unhesitatingly placed it there. 

 But if the young fertile fronds be examined, it will be evident that the 



involucre is by no means marginal; for there is a considerable space 

 of tig of frond between it and the margin.
