FLORA OF THE CHEYENNE SANDSTONE OF KANSAS, 
form and consist of about 22 .scales spirally 
arranged, as compared with about 30 in the 
cones of the modern redwood. The axis is 
stout and fusiform. The scales have a thin 
rounded peduncle. expanding distad into a 
rhomboidal peltate tip only slightly wider than 
high, with a wrinkled marginal face surround- 
ing a central laterally elongated umbilicus. 
Length of cone (maximum), 2.4 centimeters; 
diameter (maximum), 1.8 centimeters. Aver- 
age size somewhat smaller. Length of scale 
(maximum), 8 millimeters; width, 6.5 milli- 
meters; height, 4.5 millimeters. These cones 
are remarkably like those of the existing red- 
wood (Sequoia sempervirens) in every respect— 
size of axis, shape of scales, etc.—except that 
the scales are less numerous in the fossils and 
the maximum size of the scales is about six- 
sevenths that of the average redwood scale. 
The average size of the fossil cones is from 
two-thirds to five-sevenths that of the modern 
cones. . 
The condition of preservation of these cones 
is a strong argument in favor of the eolian 
character of the sandstone. All have the 
scales somewhat shriveled and widely separ- 
ated and are exactly comparable to thoroughly 
dried redwood cones. They are exceedingly 
abundant in the sandy phases of the Cheyenne 
sandstone, as if they had been blown about by 
winds and accumulated in hollows. I have not 
encountered them in the clays, although the 
clays contain specimens of the foliage. 
Whether or not Sequoia condita occurs at any 
other horizons or localities is problematic and 
can be determined only by the best of evidence, 
for, as I have alréady stated, the foliage is 
duplicated more or less closely by a variety of 
unrelated conifers. In particular the Upper 
Cretaceous conifer. known as Widdringtonites 
subtilis, a form that I have not mentioned 
above, has foliage very like the more slender 
twigs of Sequoia condita, and in the absence of 
cones I doubt if the two could be distinguished. 
However, a single specimen of. Widdringtonttes 
subtilis found in the Tuscaloosa formation of 
Alabama had small four-valved cones entirely 
unlike those of Sequoia condita. 
The Cheyenne sandstone localities are as| ter 
follows: Cones and foliage, black hills near 
Belvidere (773); 14 miles northwest of Belvi- 
dere (2218); Champion (Wildcat) Draw, three- 
fourths mile south of Belvidere (2222); near 
211 
Medicine Lodge Creek, 2 miles west of Belvi- 
dere (2224); left bank of middle branch of 
Champion (Wildcat) Draw, half a mile south of 
Belvidere — (2224); right bank of same draw 
(2281) ; Osage Rock, near Belvidere (7406). 
Foliage only, Stokes Hill, 100 yards south of 
National Corral (2219); “Lanphier shales” in 
Champion (Wildcat) Draw, three-fourths mile 
south of Belvidere (2223); “Lanphier | shales” 
in a draw 1 mile southwest of Belvidere (2225) ; 
hills between Spring Creek and Soldier, 4 miles 
northeast of Belvidere (2227) ; Champion (Wild- 
cat) Draw, right (east) branch, half a mile 
south of Belvidere, in “Lanphier shales” 
(2228) ; first draw west of Champion (Wildcat) 
Draw, half a mile south of Belvidere (2233).

Leaves narrow, needlelike, 10 to 15 centime- 
ters in length, aggregated in bundles. Bundles 
apparently borne on short shoots, with many 
leaves in each bundle. No satisfactory vena- 
tion can be made out. Fontaine described a 
number of veins in these forms, but as nearly 
as can be determined these are simply folds 
due to compression or the angles of the leaf. 
This species has a considerable geologic as 
well as geographic range, having been recorded 
from the Kootenai formation of British Co- 
lumbia, the Fuson formation of the Black 
Hills, and the Potomac group in Maryland and 
Virginia. In the Potomac group it is of fre- 
quent occurrence and individually abundant, 
being found in the oldest as well as the young- 
est beds, but much more commonly in the lat- 
er. The remains are always poorly preserved 
and were evidently much macerated before 
fossilization. Théy are closely comparable 
with Pinites solmsi Seward, of the Wealden, 
and with Pinus peterseni Heer, from the Kome
