10 THE PALEONTOLOGY OF MINNESOTA. 
DESCRIPTION OF SPECIES OF CRETACEOUS FOSSIL PLANTS 
OF MINNESOTA. 
1. Pinus species. 
Leaf comparatively very long, narrow, linear, medial nerve broad; borders flat, irregu- 
larly very thinly striate lengthwise. 
The fragment of a leaf 11 cm. long, 24mm. broad, is as far as ean be seen that ot 
a simple leaf of a Pinus, much like Pinus hayesiana Heer, of the Tertiary of Green- 
land. The medial nerve is obsolete in some parts of the leaves, very distinct in 
others. 
Hab. North side of the Big Cottonwood river near New Ulm. 
Mus. Reg. No. 5160. 
2. SEQUOIA WINCHELLI, sp. nov. 
PLATE A, FIG. 1. 
First An. Rep. Minn. Sur., p. 114. Final Rep., Vol. I, p. 354. 
Branches slender, leaves linear-oblong, obtuse, gradually narrowed to a linear decurring 
base, disconnected from the branches, at least in the upper part; medial nerve thin, sometimes 
obsolete; surface transversely rugulose under the thin epidermis. 
A beautiful species with slender pinnately divided branches; leaves and 
branchlets subdistichous and sub-opposite, half open; leaves 8 mm. long or a little 
less, 14 to 2 mm. broad at the middle, equally narrowed upward to an obtuse apex, 
and downward to a narrow linear prolongation, decurring upon the branches, but 
disconnected from them in the upper part or under the point of union to the 
leaves. 
The only relative known to the species is Sequoia brevifolia Heer, abundantly 
found near the base of the Laramie group formation at Point of Rocks, Wyoming, 
and also in the Miocene of the Baltic in Germany. The leaves of the Cretaceous 
species are narrower, their base more distinctly decurrent and detached from the 
stems. 
Hab. Austin, Minnesota. 
Mus. Reg. No. 115.
