312 BOTANY. 
bipinnate; pinne very numerous, closely placed, ovate-lanceolate, 3-13 
inches long; the lowest pair not enlarged, but usually smaller than those 
next following; pinnules mostly triangular-oblong, rather acute, oftenest 
auriculate on the upper side at the base, or in larger fronds having several 
teeth or lobes on each side; texture rather firm, surfaces green and glabrous; 
involucres pale, membranaceous, interrupted only by the incising of the 
pinnules—Amer. Jour. Sci. July, 1848, p. 87; Hook. Sp. Fil. ii, p. 89, t. 
103; Fil. Exot. t. 90 (admirable). Pteris Alabamensis, Buckley, Am. Jour.

Mouth of Rio Pecos, Dr. Bigelow. Lower Rio Grande, Schott. Alabama avd Tennessee to the 
borders of Virginia. This pretty little Fern is more slender than C. microphylla, and has narrower and 
more acute pinnules and paler involucres, but is nevertheless so closely related to it that Sir William 
Hooker had grave doubts of its tintin In removing it to the genus Pella, Mr. Baker hs certainly 
separated it from its nearest allie 
** Frond somewhat hairy and glandular, but not tomentose. 
Cheilanthes leucopoda, Link. 
Stalks 3-4 inches long, pale straw-color, stout for the size of the frond, 
chaffy at the base with soft narrow rusty scales; frond about 3 inches 
long, deltoid-ovate, at the base 4-pinnate, gradually simpler upwards, every- 
where glandular-puberulent ; lowest pair of pinnee unequally deltoid-ovate; 
upper ones oblong; secondary ones oblong, short-stalked; ultimate ones 
divided into minute rounded lobules, which when fertile are strongly revo- 
lute, concealing the sporangia.—Fil. Sp. Hort. Berol. p. 66; Mettentus, tiber

valde Cafion, Rio Nueces, Texas, Mrs. M. J. Young, 1876. Also found in Mexico. Though not 
yet discovered within the limits assigned to the present work, I have thought best to include this species, 
as it is a very recent addition to the Ferns of the United States, and will, with very little doubt, be found 
before long in New Mexico or Aricona. From C. viscosa, Kaulf., under which it is mentioned in Species 
Filicum, it differs by havi and very much paler stalk (nearly black in the other), and a rather 
smaller and more rigid frond. Its general shape and composition are much the same as in C. Californica, 
but the plant bears a lax glandular pubescence, and has rounded very obtuss ultimate segments. C. 
viscosa is attributed to New Mexico in Species Filicum, but I have never,seeu any specimens from that 
Territory. The above notes will serve to distinguish it, if collected. 
Cheilanthes Cooperz, D. ©. Eaton. 
Stalks densely tufted, variable in length, brownish, fragile, hairy, 
like the frond, with entangled or straightish nearly white articulated often 
gland-tipped hairs; frond 3-8 inches long, ovate-lanceolate, bipinnate; the
