To Mr. John C. Nimmo, Publisher, London, the Author is in- 
debted for the use of the Illustrations, and for which he offers his 
thanks.* 
* The Author is aware that some of the varieties are not sufficiently distinct to 
be retained ; this, however, can be more satisfactorily discussed by the Fern 
Conference from a careful examination of fronds. A few additional varieties 
will be found in an Addendum.
