FLORA OF THE CHEYENNE SANDSTONE OF KANSAS. 
records all represent the same species, it was 
evidently a wide-ranging type in the earliest 
stage of the Upper Cretaceous, which spread 
from the Arctic region southward into North 
America, Europe, and Asia. There are five 
specimens in the Cheyenne sandstone that 
appear to be identical with Heer’s Greenland 
forms, but as they are preserved in a coarse 
sandstone their detailed characteristics are 
obliterated. The pinnules are coriaceous, long, 
and narrow and somewhat resemble what 
Heer ” called Gleichenia rigida. 
Although details of frond habit and fructifi- 
cation are lacking I have ventured to transfer 
this form from Pecopteris to Gleichenia, as it. 
appears to be congeneric with the numerous 
Cretaceous forms of that genus. 
It was found in the Cheyenne sandstone on 
the left bank of the middle branch of Cham- | 
pion (Wildcat) Draw, half a mile south of 
Belvidere (2229).

Hill ? states that there is some doubt as to 
the occurrence of this specimen at this horizon. 
Lester F. Ward, who subsequently visited the 
locality, states that he was satisfied that, it 
could not have come from the Cheyenne sand- 
stone but may have weathered out from the 
overlying ‘‘Reeder sandstone.”” The material, 
which is only a fragment, has never been 
studied by a competent person, although 
Ward states that it is surely a fragment of a 
cycad trunk. 
Whatever its true horizon it is of interest as 
one of the latest authentic occurrences of this 
type of plant. 
’ Genus CYCADEOSPERMUM Saporta. 
Cycadeospermum lineatum Lesquereux.

Mon. 17, p. 30, pl. 1, fig. 14, 1891 [1892]. 
This seed, which was found 10 miles north- 
east of Delphos, Kans., was described by 
Lesquereux as follows:

Seed oblong-ovate, slightly falcate, rounded at the 
lower end, short acuminate at the other; testa smooth, 
transversely lineate, the lines distant, parallel; carena 
clearly marked longitudinally on both sides, the inner 
concave, the outer rounded. 
“Length 1 to 1.5 centimeters; width about 
6 millimeters, somewhat compressed. Testa 
thick, shining, and ligneous. 
Cycadophyte seeds are not so inequilateral, 
and the present form is probably angiosperm- 
ous. This genus was proposed for Jurassic 
forms, of which many have been described. 
A few have been described from both Lower and 
Upper Cretaceous material. The Cheyenne 
form is certainly identical with Lesquereux’s 
type. Whether or not it is congeneric with 
the other species referred to Cycadeospermum, 
or whether indeed it represents the seed of a 
cycadophyte and not an angiosperm, can not 
be determined. My impression is that it 
belongs to the latter rather than the former. 
Material identical with Lesquereux’s type is. 
found in the Cheyenne sandstone 14 miles 
northwest of Belvidere (2218) and near Medi- 
cine Lodge Creek, 2 miles west of Belvidere 
(2224).

The inextricable confusion that results from 
the identification of detached fragments of conif- 
erous foliage when they can not be checked 
by fruits or in some other way is well illustrated 
by the forms that are variously referred to 
Glyptostrobus gracillimus Lesquereux, Sequoia 
gracillima Newberry, Widdringtonites reichii 
Heer, etc. In volume 6 of the final reports of 
the United States Geological Survey of the 
Territories Lesquereux gave figures of a plant 
which he had named some years earlier Glypto- 
strobus gracillimus and which he compared with 
Frenelites reichia of Ettingshausen. When
