CHAPTER X. 
FOSSIL PLANTS OF THE UPPER PALEOZOIC/OF KANSAS. 
BY E. H. SELLARDS. 
HE Upper Paleozoic of Kansas, from which the plants de- 
scribed in this paper were obtained, includes a continu- 
ously deposited series of formations extending through a 
stratigraphic interval of some 3500 feet. For a detailed geo- 
logic scheme of the formations, names, and order of succession, 
reference should be made to the earlier chapters of this volume. 
Loealities and Collections, 
The collections forming the basis of this study are contained 
in the museum of the University of Kansas. They consist, first, 
of large collections from a few favorable localities, made many 
years ago by Judge E. P. West under the direction of Dr. F. H. 
Snow; and second, of collections from a number of localities, 
made more recently under the direction of the present Geo- 
logical Survey. Certain plants supplementing the University 
collection were kindy lent by the U. S. National Museum 
through Mr. David White. In addition an extensive collection 
of plants from the Lansing mines were also lent by Mr. J. M. 
Gilman. 
Plants have been obtained from the following formations 
and localities: 
- CHEROKEE STAGE. 
Leavenworth, near Lansing, Kan.—In addition to the collec- 
tions from this locality contained in the University of Kansas 
museum, Mr. J. M. Gilman, of Leavenworth, very kindly lent 
for study his collection from the State Penitentiary mine at 
Lansing. 
POTTAWATOMIE STAGE. 
Bethany Falls Limestone.—Two small collections of plants 
have been made from the Bethany Falls limestone along the 
bluffs on the south side of the river at Kansas City, Kan., just 
within the state line, and near the base of the Bethany Falls 
group.
