THE FERN BULLETIN 



4 cm. in width, tapering from above the middle to the 

 base, thickish, dull green in color, nearly pinnate be- 

 low, pinnatifled in the upper portion ; divisions of the 

 blade alternate, spreading or ascending, rounded in 

 small fronds, longer and obtuse in larger ones, the 

 margins entire or wavy ; sori, heavy, elongated, 5 to 

 10 on a segment, the basal ones nearly parallel to the 

 midrib : Indusium thin, nearly disappearing in old 

 fronds, veins free, one to three times forked. 



Habitat : Under dryish shelving rocks between 

 Brown and Tanner's Canyons, Huachuca mountains, 

 Cochise County, Arizona. Collected October, 1907 by 

 James H. Ferriss, for whom I take pleasure in naming 

 the species. Type in my own herbarium. 



The locality in which the plant was found is about 

 five miles from Conservatory (Ramsey*) Canyon in the 

 direction of Fort Huachuca and six miles or more 

 from the Mexican boundary. It was growing in lo- 

 cations similar to those selected by Aspidum ju gland i- 

 folium and Polystichum aculeatum lobatum. 



The plants have a passing resemblance to Asplenium 

 ebeneum but could not be mistaken for it even by a 

 novice. The stipes and midrib are greenish, the pin- 

 nules broad and in the upper part of the frond the 

 sinuses between them are from 3 to 5 millimeters from 

 the midrib. The long and heavy sori and the spread- 

 ing habit of even the fertile fronds are especially char- 

 acteristic. Young forms of this species have undi- 

 vided elliptical fronds. About 75 specimens of this 

 plant are at present growing in cultivation in Joliet, 

 Illinois.
