and were thought by Dr. N. L. Britton to be portions of grass 
leaves, allied to or identical with Zizanza.* Some of these are de- 
picted in figs. 1, 2 and 3, plate 313. 
A yet smaller fragment, represented by fig. 6, plate 311, was 
submitted to Prof. Leo Lesquereux, who identified it as “Cyperites, 
spetr tf ; 
Material subsequently collected by the late Dr. J. I. Northrop, 
by the Geological Survey of New Jersey and by me personally 
indicates that the fragments are not parts of single blade-like 
leaves, but dismembered portions of palmate leaves, like those of 
a fan palm, connected toward the petiole and separated into free 
_ divisions toward the margin. 
Basal portions I consider to be represented by figs. 2-5, pl. 313, 
which are narrow and strongly plicated or folded; median portions 
by figs. 1-4, pl. 312, and figs. 1,6 and 7,pl. 313. In figures 1 
and 6 of the latter plate the place of separation of the free divi- 
sions is indicated atthe summits. Portions of the free divisions are 
apparently represented by figs. 1-3, pl. 311, and portions of the peti- 
oles by figs. 4 and 5, pl. 311. Leaves of U/mus plurinervia Ung. 
and Quercus Klipsteinit Etts., included respectively in figs. 1 and 5, | 
pl. 311, have no special significance, except as an indication of the 
accompanying vegetation, which, it is hoped, will be described in 
full at some future time. The almost total absence of surface stri- 
ations I believe may be accounted for by the character of the me- 
dium in which the fragments are preserved—a rather coarse, fri- 
able sandstone. 
Upon examining the literature of tertiary palaeobotany many 
fragments similar to ours may be found described and figured by 
Gaudin, Heer, Watelet and others, under the genera Cyferites,t 
Flabellaria,§ Phoenicites,|| Anomalophyllites,§ etc.—the first one sup- 
posed to represent the sedges, the others palms.
