SELLARDS.] Fossil Plants, Upper Paleozoic, Kansas. 417 
tional Museum labeled by Monsieur Zeiller. The species is 
much like some specimens of O. lingulata, figured in European 
literature, but is distinguished from that species by a more 
strongly developed median fascicle of veins in the large pin- 
nules and by the greater number of dichotomies of the veins, 
the last being closer to the border. 
Formation and locality: Le Roy shales, Haverkampf farm.

Pinnules large, of. various shapes, anomalous, ovate-oblong 
or elongate, sessile by the base, often decurrent, open or 
curving back, borders entire or obtusely lobed, bordered or 
scalloped, or divided by acute sinuses into triangular pointed - 
lobes. Veins very numerous, many times branched, sinuous, 
close when near the border, often uniting for some distance, 
then separating again. Rachial veins numerous. Midvein 
of the large, long pinnules moderately strong, branching some 
distance above the middle, giving off numerous branches which 
curve and meet the border at right angles, forking four or five 
times, becoming near the border very sinuous, often running 
into each other, and remaining contiguous for a greater or less 
distance. 
Many specimens of this anomalous type have been obtained 
from the Haverkampf farm near Lawrence. There is seem- 
ingly no regularity of size or shape to the pinnules. A form 
in which the pinnule is unsymmetrical, its borders acutely 
lobed, is quite common. Others are ovate or ovate-oblong, with 
borders entire. The number of veins, the angle at which they 
fork, and especially the last dichotomy close to the border, sug- 
gest the associated plants which I have referred to O. genuina. 
The fossil plant collection of the Yale Museum contains a few 
pinnules from Mazon Creek which seem to be referable to 
this species, the shape of the pinnule and character of the 
venation being very much the same. The Mazon Creek plant 
in turn is very similar to some of the pinnules from that lo- 
cality referred by Lesquereux to N. carrit. 
Formation and locality: Le Roy shales, Haverkampf farm.
