Nephrodium Floridanum Hook, makes a new record 

 in appearing at Thomasville. Hitherto it seems to have 

 been reported only from Florida,. Alabama and Louisiana ; 

 but at Thomasville it grows in great luxuriance in shade 

 on the hammocks, and is the most noticeable species of 

 the region. 



Adiantum hispidulum Sw. Mrs. Taylor's specimens 

 of this fern differ from typical specimens from New 

 Zealand, Ceylon and other East Indian islands. While 

 the fronds are abundant and of normal size, the fruit, 

 which it usually produces so prolifically, is very sparse 

 on these specimens, the venation is more strongly striated, 

 the upper and outer edges more deeply serrated, the 

 pinnules falcate, and instead of standing at right angles 

 to the rachis, or nearly so, they stand at an angle of about 

 60 degrees to it. as they do in A. pe datum rangifcriiutm. 

 These features give it a peculiar character, induced per- 

 haps by its environment, as it. grows in a hanging posi- 

 tion in the red clay walls of old wells and under the edges 

 of verandas. In fact, it is so distinct that it seems 

 worthy of a formal name, and I have designated it 

 Adiantum hispidulum f. strictum f.u.

A CHECK LIST OF THE NORTH AMERICAN 

 FERNWORTS. 



By Willard N. Clute. 



The making of fern lists began in America somewhat 

 earlier than the making of fern books themselves, and 

 has continued with increasing interest to the present. The 

 grace and beauty of the ferns, the ease with which they 

 may be preserved and the great variety of species found 

 in our part of the world have all fostered the collecting 

 spirit which is at the very foundation of fern study, while 

 the fern lists have afforded a convenient means of check-
