knowlton.] DESCRIPTION OF SPECIES. fil 
Among fossil species a number may be mentioned that have more or 
less resemblance to the one under consideration. Thus Cinnamomum 
polymorphum Heer 1 may be mentioned. This species lias much the 
same shape as the Coalville example, but differs in having the lower pair 
of secondaries at a sharper angle. They branch on the outside, and also 
ascend higher toward the point of the blade. Perhaps the closest 
species is C. ellipsoideum Sap. and Mar., as figured by Lesquereux- 
from the Dakota group of Fort Harker, Kansas. This leaf is very 
much like C. Stantoni, being, however, more nearly ovate in outline, 
with a thicker, much larger petiole, and with the lower pair of second- 
aries nearer the base of the blade and passing up for a longer distance. 
It is certainly very suggestive of the Montana species. 
Tbe species is named in honor of the collector of the specimen, 
Mr. T. W. Stanton. 
Habitat. — Coalville, Utah.

The only specimens ever obtained of this species are the two figured 
in the Tertiary Flora, both of which are preserved in the United States 
National Museum (Nos. 530, 531). They were well described and their 
affinities pointed out by Lesquereux, to which there is nothing to add. 
Habitat. — Point of liocks, Wyoming.

p. 514 (1878) ; Tert. FL, p. 259, PL LXII, fig. 12 (1878). 
The type of this species is not now, and according to the records has 
never been, the property of the United States National Museum. It 
appears to have been carefully described and figured, and as no addi- 
tional material has been obtained from the type locality, its present 
status must remain. 
Habitat. — Point of Kocks, Wyoming.

Leaf evidently thick in texture, broadly cordate, with rounded base 
and very deep sinuses, rounded, truncate at apex; margin undulate 
lobed, the lobes very short, obtuse, and entire or erose; nervation pal- 
mate, with about seven primary nerves of equal strength which appar-
