THE FERN BULLETIN 



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

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

 low, pinnatified 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; son", 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 juglandi- 

 folium and Polystichum aculeatum lobatum. 



The plants have a passing resemblance to Asplenium 

 cbeneum 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. '
