26 FLORA OF THE MONTANA FORMATION. 
I am familiar, I have preferred to retain it under that genus until more 
perfectly preserved material may possibly clear up its relationship. 
It is also very similar to 8. Berthoudi, from which, however, it differs 
in having apparently two-ranked foliage leaves. It can hardly belong 
to any fern type of vegetation, as Lesquereux has suggested, nor can 
it be a conifer. 
Lesquereux has also referred to this species a single specimen (cf. 
Tert. Fl., PI. LXIV, figs. 13,13«), with a thick stem closely covered with 
leaves of the same shape as those of the typical form of 8. falcata, with 
the remark that it probably represented a primary stem of the species. 
As above noted, this has been referred to Lycopodium, under the name 
of L. Lesquereuxiana. 
Habitat. — Point of Rocks, Wyoming. Originally collected by F. V. 
Hayden and William Cleburn, and later by Lester F. Ward. 
Pinus Quenstedti Heer. 
PI. Ill, fig. 10. 
Pinus Quenstedti Heer, Fl. v. Moletein : Neue Deukschr. Schw. Gesel. Naturwiss., Vol. 
XXIII, mem. 2, p. 13, PI. II, figs. 5-9; III, figs. 1-2 (1869) ; Lesquereux, Bull. U. S. 
Geol. and Geog. Surv. Terr.', Vol. I, p. 392 (1875) ; Cret. and Tert. Fl., p. 33, PI. I, 
figs. 3, 4 (1883 [1884]). 
The specimens which Lesquereux referred to this species were 
obtained from the Dakota sandstones of Fort Haiker and Clay Center, 
Kansas. While they much resemble the specimens described and 
figured by Heer, there are certain differences which render the 
identification more or less doubtful. The cone in the Moravian 
examples is always straight, while in the Kansas specimens, according 
to Lesquereux, they are always curved. The scales in Heer's specimens 
are rhomboidal, being scarcely wider than they are high, while in the 
American specimens they are decidedly wider than high. The spines 
or tubercles also differ. These are, perhaps, minor differences, but they 
are such as may be observed in closely allied living species. 
The single fragment figured is the only one found in the Wyoming 
material. It obviously comes from near the middle of a large cone, but 
there is hardly a sufficient length of it to show whether or not it was 
curved. The form of the scales and, as nearly as can be made out, the 
tubercles or spines, are also the same. There is, therefore, not much 
doubt that it is the same as the American specimens referred to this 
species. It is more than likely, however, that when sufficient material 
is obtained it can be shown beyond reasonable question that the 
American material is not identical with the European. 
The specimen figured has been kindly loaned by Prof. W. C. Knight, 
of the University of Wyoming. 
Habitat. — Near Fort Harker and Clay Center, Kansas. Dunn's 
ranch, 6 miles east of Harpers Station, Wyoming.
