A NEW FERN FROM THE UNITED STATES. 



By Willard N. Clute. 



Collectors of the ferns have so carefully explored 

 every easily accessible part of the United States, that 

 a new fern is a rarity, indeed, and only to be found by 

 penetrating beyond the bounds of even frontier civili- 

 zation. The opinion has often been expressed in 

 these pages, however, that the southern parts of our 

 territory would still yield several more ferns that were 

 either new to science or new to the United States, and 

 this opinion has recently been substantiated by the 

 finding in southern Florida of various species new to 

 our flora. It is probable that other species will eventu- 

 ally come to light in that state, as the exploration of 

 unsettled parts continues. 



A second region from which we may expect addi- 

 tional species from time to time is that part of the 

 United States which borders Mexico. In the past 

 several unique species have been reported from the 

 canyons of New Mexico and Arizona and the recent 

 trip to that region made by Mr. James H. Ferriss, has 

 resulted in the discovery of various new forms. One 

 of these is so unlike anything I have been able to find 

 described, that I venture to name it a new species as 

 follows : 



ASPLENIUM FERRISSI Sp. 110V. 



Rootstock small, erect ; fronds oblong-lanceolate, 

 short-stalked, spreading, 8 to 15 cm. in length; 2 to
