Cheilanthes viscida, n. sp.—Roots tufted; stipes 2’ to 4’ long, 
very dark brown, densely clothed at the base with light brown, nar- 
rowly lanceolate or linear, long-pointed, entire scales, and with a few 
scattered, small, thin scales, or none, above, glandularly rough ; 
fronds light green, 3’ to 5’ long, #’ to 1’ broad, lanceolate, 2 to 3 pin- 
nate, covered, especially beneath, on the rachis and upper part of 
main stalk, with distinct, sticky, resinous glands ; pinne deltoid, short- 
stalked, lowest pair distant; pinnules ovate-lanceolate or oblong, basal 
one sub-sessile, lower series longest and sub-pinnate or deeply pinna- 
tifid, upper series pinnatifid, cut down into narrow oblanceolate 
divisions, decurrent on the broadly-winged rachis, the segments again 
cut into 3 to 5 lobes, the recurved tips forming distinct involucres, 
Hab. California, clefts of rocks ? 
First collected by Mr. J. G. Lemmon on the White Water Canyon 
in the Colorado Desert, afterward at Downieville Buttes (Mr. 
Lemmon), and later, April, 1876, on the eastern (desert) slope of the 
Sierra Nevada, near San Gorgorio Pass, by Dr. Parry and Mr. 
Lemmon (No. 427, Flora Southern California). 
The species appears intermediate between C. vestita, Swartz, and 
C. Coopere, Eaton, but the former differs from it in its larger size, 
its hairiness, and the total absence of glands; while the latter may 
be readily distinguished by the darker scales at the base of the stipes, 
its broader, less divided fronds, more obtuse divisions, and especially 
by its very distinct glandular-tipped hairs. The species will be fig- 
ured in an early number of the ///ustrations of the Ferns of North 
America, noticed in the August No. of the BULLETIN, p. 169.

§ coz. Publications.—1. Mores on Botrychium simplex, Hitch., 
by Geo. E. Davenport: This monograph will delight all who enjoy 
a work thoroughly well done, both in the treatment of the subject 
and the typographical investment. Prof. John Robinson, of Salem, 
Mass., has had printed but a very small private edition, at the low 
price of one dollar, including postage, and we advise all lovers of 
ferns to apply for it without delay, as we confidently predict that in_ 
a short time it will only be procurable for its weight in silver at_ 
least. Size, rox12 inches; pages, 22; elegantly printed on heavy plate © 
paper. It is now clear from Mr. Davenport’s investigations that _ 
Prof. Hitchcock’s original drawing represents a distinct species, but 
that his description was made partly from immature specimens of 
this or perhaps some allied species. The object of Mr. Davenport 
was to determine “some external character by which the species 
may be distinguished from the other small Botrychiums.”” He finds 
_ this in “the presence of two stalked divisions, approximate to the 
rhizoma, in precisely the same manner as in B. ternatum.” In two 
plates, drawn by Emerton after tracings made by Mr. Davenport 
from the specimens themselves and engraved by the heliotype pro- 
cess, he has illustrated the forms from nearly every known locality. 
The first plate, with the exception of three of -Hitchcock’s dubious © 
specimens, represents the true B. simplex; the second, the forms 
which have been mistaken for it. There are in all about 50 figures,
