 calities are remarkably uniform. The names oi Aspidia uniliim, jirojnnquum, 

 gongylodes, and Serra, have been long familiar ; but it has never been in our power 

 to distinguish them at all satisfactorily. The first and last of them {A. unitum and 

 A. Serra), as regards the plants of Schknhr, are figured by that author on the same 

 plate of his Filices, Tab. 33 b, and so like each other that I had considered them 

 one and the same ; but A. Serra is referred by Presl and Moore to Lastrea, and 

 if that is correct, as I believe it to be, it needs not be considered here. In the 

 matter of A. unitum, I follow Mettenius's views, and consider Sieber's plant so 

 called as the authority. A. gongylodes I fear must be united with propinquum ; 

 but propinquum itself has been a puzzle to many. In this I am willing to take 

 the accurate Drown for my guide, and I presume that Swartz, in his ' Adnota- 

 tiones' (published in 182'J), has adopted Brown's propinquum (i)ublished in
