Vol. VI, No, 5.] BULLETIN of THE ToRREY BOTANICAL Cuus. [New York, May, 1875, 
§ 26. New or Little-known Ferns of the United States.—No. 3. 
7. Cheilanthes myriophylla, Desvy.—A well-known Mexican and 
South American Fern, but very rare in the United States. It much 
resembles Ch, Fendleri, Hook, but is rather larger, and has the under 
surface matted with a fine tomentum under the scales, while C. 
Fendleri has the scales only, and these mostly confined to the mid- 
ribs and divisions of the rachis. It was collected several years ago 
in “South California” by Dr. Arthur Schott, in Arizona in 1866 by 
Mr. Clarence King, and in the same territory in 1870 by Dr. E. 
Palmer, 
8. Cheilanthes Clevelandii, sp. nov.—Fronds (4-10 inches high) 
ovate-oblong, tripinnate with closely set minute roundish seg- 
ments, smooth above, beneath densely covered with minute imbric- 
ating, cinnamon-brown, ovate, ciliated and laciniated scales, growing 
on the segments as well as on the midribs; segments flattish, the 
margin narrowly recurved and unchanged in texture.—Growing on 
a mountain about forty miles from San Diego, California, at an ele- 
vation of about 2,500 feet, Mr. Daniel Cleveland. While closely. 
related to C. myriophy/la and C. Fendleri this Fern is easily dis- 
tinguished by the deep fulvous color of the scales, which are elegant- 
ly ciliated,the cilia recurved and visible from the upper surface of 
the frond. The rootstock is apparently rather short, and scaly as 
in the related species. The stipes from two to six inches long, 
dark brown, and, like the rachis, beset with narrow rigid scales. 
9. Cheilanthes Cooper, sp. nov.—Fronds (4—8 inches high) 
ovate-lanceolate, hairy, like the brownish fragile stipes, with en- 
tangled or straightish, nearly white, articulated, mostly gland-tipped 
hairs, twice pinnate; the rather distant pinne oblong-ovate, pin- 
nules roundish-ovate, crenate and incised, the ends of the lobules re- 
flexed and forming herbaceous involucres, segments at length flat. 
—California ; near Santa Barbara, Mrs. Ellwood Cooper; Sierra 
Valley, Mr. J. G. Lemmon —This has much the appearance of the 
Eastern C. vestita, which ranges from New York to Kansas, but has 
never been found west of the Rocky Mountains. In C. vestita the 
hairs are always very acute, while in C. Coopere they are usually 
tipped with glandular and, I think, viscid enlargement. I take great 
pleasure in giving for the first time to an American Fern the name 
of a lady botanist. : : 
10. Cheilanthes microphylla, Swartz.—This species was collected 
by the Botanists of the Mexican Boundary Survey, many years ago, 
together with C. Alabamensis, Kze. The latter has just been sent 
again from Austin, Texas, but the former has not been received a 
second time from anywhere within our limits. i 0. Ree
