estern America, from Mexico to Chile, and reported from India also, Arizona, Mr. Clarence 
King. California, Monte Diablo Range, Prof. Brewer and Dr, Gibbons. Rocks, near the Gould and 
Curry Mill, Nevada, H. G. Bloomer. San Diego, Mr. Cleveland. The specimens which I refer to this 
specics I had formerly supposed to belong to C. Fendleri, but a closer examination shows that the scales 
of the frond are narrower, and not entire, and that the whole plant is more or less tomentose as well as 
chaffy. She Californian specimens and those from Nevada are much smaller than those commonly sent 
rom Mexico and South America. C. elegans, Desy., was founded on a Chilian plant with more obovate- 
pert ultimate segments. It is maintained as ‘distinct by Fourcier, and specimens agreeing pretty 
well with its characters have been collected, since this report was prepared, at Cajon Pass, California, by 
Mr. William Stout. But they seem to be also nearly inseparable from C. Fendleri. 
Cheilanthes Lindheimeri, Hooker. 
Rootstock slender, elongated, creeping, branched, chaffy with thinnish 
ovate rusty scales; stalks scattered, 4-7 inches high, blackish-brown, 
polished, wiry, at first bearing narrowly lanceolate delicate scales inter- 
mixed with woolly hairs; frond 3-5 inches long, ovate-lanceolate, 3—4-pin- 
nate; pinnz mostly close-set; ultimate segments roundish-pyriform, about 
4a line long, very much crowded, the unchanged margin much incurved ; 
upper surface of frond white-tomentose, lower surface very chaffy with pale 
or ferruginous scales, those of the midribs ciliate at the base, those of the 
ultimate segments more and more ciliate and passing into entangled tomen- 
tum.—Sp. Fil. ii, p. 101, t. 107, A. 
Western Texas to New Mexico and Arizona, Lindheimer, No. 744; Wright, No. 817 ; King, Rothrock, 
Palmer, etc. Plant with a long and slender rootstock, by which, and by the white-tomentose upper 
surface of the frond, it is to be distinguished from C. myriophylla. The ultimate segments are much 
smaller than in that species, and are also much more compactly arranged. 
CHEILANTHES VESTITA, Swartz, and C. ARGENTEA, Kunze, are the only other species of the 
genus attributed to the United States. The former ranges from New York to Northern Alabama, and 
westward to Kansas. The latter is a species of Northern Asia, which is said to have been collected in 
Alaska by Steller. C. aspera, Hooker, will be found described in the genas Pellwa, to which Mr. Baker 
has very properly referred it.
