FLORA OF THE GREEN RIVER GROUP
ROSA, Linn.
Rosa Hilliæ, sp. nov.
Plate XL, Figs. 16, 17.

Leaves small; leaflets oval, obtuse or short-pointed, serrate; stipules large, lancelolate, acuminate; nervation camptodrome.
These beautiful small leaves represent this genus more distinctly than any of the other fossil leaves which as yet have been referred to it. The leaflets are rather obtuse, the lateral much smaller, 5 to 15 millimeters long, 3 to 7 millimeters broad — all short-pediceled like the terminal ones; the nervation is camptodrome, the figure shows it mostly craspedodrome, a mistake evidently, for as seen on the left side of the largest pinnule, fig. 16, the veins are curved. The nervation near the borders is not quite distinct on the specimens.
