deltoid-lanceolate or oblong, pinnules next the main rachis often lobed ; all 

 of them very rough on both surfaces, with short harsh simple or forked 

 whitish hairs ; involucres continuous, the edges crenate. — Syn. Fil. p. 148.

New Mexico ami Western Texas, Charles JViight. This Fern is peculiar among our species of tbe 

 genus in having a harsh scabrous surface. Hooker noticed that the margins of the fertile piuna3 are 

 transversely waved, and that the often forked or tripartite hairs are most abundant on the top of these 

 undulations. One specimen shows a rootstock as thick as a crow's quill, an inch or so in length, and 

 branched near the growing end. 



-t--i- Frond hi — tri — quadripinnate, ultimate segments oval or cordate. 



Pellaea aiiflroiucdrefolia, Fee. 



Rootstock slender, creeping, covered with narrow glossy scales ; 

 stalks scattered, erect, wiry, pale-brown, smooth and naked, except for the 

 narrow chaff at the base, 2-12 inches long, about equalling the ovate 

 usually tripinnate but sometimes 2-4-pinnate fronds ; primary piunas rather 

 distant, spreading ; ultimate pinnules 2-5 lines long, petiolulate or sessile, 

 oval, slightly cordate and emarginate, fleshy-coriaceous, the fertile ones 

 often with the edges revolute to the midrib ; veins numerous, parallel, and 

 sometimes producing narrow ridges on the upper surface ; involucres her- 

 baceous, with a narrow whitish edge. — Genera Filicum, p. 129. Pteris

California, mostly iu the Coast Ranges, but collected in the " mountaius near Live Oak Creek " 

 and one or two other places (iu Arizona?) by the Botanist i of the Mexican Boundary Commission. Mex- 

 ico? Also iu Chile, but the Ohiliau plant has beeu described as a distinct species (P. myrtillifolia, Met- 

 teuius & Kuhu) upou insufficient grounds. Kunze also reports a station iu Cape Colouy. The stalks 

 are commouly very straight, the rachis rarely a little rlexuose, and their color is said to be reddish-brown 

 with a delicate bloom when fresh, though dried plants show a nearly straw-colored rachis. A pubescent 

 form was noticed by Nuttall. 



Pel!a?a pulchella, Fee. 



Rootstock very short, stout, nearly erect ; stalks densely clustered, 3-8 

 inches long, chaffy at the base with narrow crisped scales, nearty black 

 and polished, as are the rachis and all its divisions ; frond as long as the 

 stalk, or longer, triangular-ovate in outline, quadripinnate below, less com- 

 pound upwards ; ultimate pinnules numerous, very small, 1-3 lines long, 

 oval or commonly cordate-ovate, obtuse, distinctly stalked, coriaceous, 

 smooth, the edges often very much rolled in ; involucre herbaceous. —
