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 and Western Texas, Charles Wright. This Fern is peculiar among our species of the 
genus in having a harsh scabrous surface. Hooker noticed that the margins of the fertile pinns are 
transversely waved, and that the ofcen 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. 
++ Frond bi—tri—quadripinnate, ultimate segments oval or cordate. 
Pellza andromedzfolia, Fée. 
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 pinnze 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 
andromedefolia, Kaulfuss, Enumeratio Filicum, p. 188. Allosorus androme-

California, mostly in the Coast Ranges, but collected in the “ mountains near Live Oak Creek” 
and one or two other places (in Arizona?) by the Botanists of the Mexican Boundary Commission. Mex- 
ico? Also in Chile, but the Chilian plant has been described as a distinct species (P. myrtillifolia, Met- 
tenius & Kuhn) upon insufficient grounds. Kunze also reports a station in Cape Colony. The stalks 
are commonly very straight, the rachis rarely alittle flexuose, 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. 
Peliza pulchella, Fée. 
Rootstock very short, stout, nearly erect; stalks densely clustered, 3-8 
inches long, chaffy at the base with narrow crisped scales, nearly 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.—
