knowlton.] DESCRIPTION OF SPECIES. 4-3 
National Museum and their location is unknown, unless possibly they 
are in the Museum of Princeton College, New Jersey. I found there 
a small slab on which six or eight fine leaves are preserved, the back 
of the slab bearing the label " La. South Park, Col." The matrix is 
the same as that of the Golden specimens mentioned above, and they 
may all belong together. In any case much uncertainty exists as to 
the actual type locality of this species. 
Professor Ward obtained some very fine material from Black Buttes, 
Wyoming, which he referred to C. affine. The specimens agree per- 
fectly with the fig. 5 mentioned above, except that they are somewhat 
larger; they are quite unlike what may be called typical C. affine as 
depicted in figs. 1-4, 7. 
I have long been of the opinion that there were two well-marked 
species included under Cinnamomum affine as figured in the Tertiary 
Flora, PI. XXXVII. The joining of the secondaries to the midrib at 
some distance above the base is distinctly a character of Cinnamo- 
mum, and all known species })Ossess it. The form represented in fig. 5, 
together with those of Professor Ward already mentioned, do not possess 
this character. The secondaries pass to extreme base of the blade and 
arise with and at the same point as the midrib. 
In a letter to Professor Ward, commenting on his Types of the Lara- 
mie Flora, Lesquereux distinctly objects to the reference of the Black 
Buttes leaves to his Cinnamomum affine^ saying that they could not 
belong to the genus Cinnamomum as above characterized, but should 
probably be allied to Ficus of the type of F. planicostata. 
The National Museum contains several rather poor specimens (Xos. 
312a, b, c) of what is apparently this species from Point of Rocks, 
Wyoming.

The first American specimens referred to this species were men- 
tioned by Lesquereux in Hayden's Annual Report for 1871 (p. 300), 
having probably been collected the previous year. He wrote as fol- 
lows of the collection of which they form a part : u Hard, shaly, fine- 
grained whitish sandstone. About the same consistence and color as 
the specimens from Carbon Station. The precise locality is unknown, the 
labels having been lost or forgotten." They are thus shown to be from 
an unknown locality, yet in all subsequent mention of the species they 
are said to have come from the Green River group. The nature of the 
matrix entirely precludes the probability of this, and this view is fur- 
ther confirmed by the accompanying species, none of which are Green 
River group species.
