SELLARDS.| Fossil Plants, Upper Paleozoic, Kansas. 453 
specimens are 17 to 23 mm. wide, probably not less than 20 cm. 
long; the West Virginia specimens are 23/4, cm. wide, and have 
an estimated length of 20 cm. 
Fontaine and White compare the species to 7. coriacea. It 
differs from specimens of that species from the same locality 
in a larger and much thinner frond, finer and more numerous 
veins, more nearly at right angles to the rachis. The two 
species are usually easily separated on these characters, but 
between the larger fronds of T. coriacea and the smaller of T. 
newberriana, aS represented in the Kansas Permian, the di- 
viding line is sometimes by no means clear. 
The species may be compared in venation to T. jejunata 
Grand’ Eury, but this latter species is described as having a 
pinnate frond, of which the ultimate pinne have a somewhat 
cordate base. JT. newberriana has a simple frond gradually re- 
duced to a petiolate base, as shown both by the West Virginia 
and Kansas specimens. Professor Potonié, Die Flora des Roth- 
liegenden von Thuringen, page 145, includes in the synonomy 
of T. jejunata, “T. newberriana Font. and White ex parte,” and 
cites plate XX XIV, figures 9, 9a, of the Permian Flora, but the 
figures referred to are not of T. newberriana, but of T. lescur- 
ana F. and I. C. W. 
The horizon from which the types of T. newberriana were de- 
scribed have been variously regarded as Permian and Permo- 
Carboniferous. Professors Fontaine and White in their treat- 
ment of the flora argue strongly for its Permian age. 
Formation and locality: Wellington shales, Banner City, 
Dickinson county. 
Tzniopteris sp. 
The apical part of a frond found in the Wellington shales 
probably indicates a third species of Txniopteria. The vena- 
tion has much the same character as that of T. coriacea, but 
the frond is evidently much larger. On the other hand the 
veins are very much more oblique than those of T. newberriana. 
The veins are thin and close, and the dots between the veins 
small and numerous. 
Formation and locality: Wellington shales, Banner City, 
Dickinson county.
