CORNUS, Linn. 
Cornus ovalis, sp. noy. 
Pov tie TS 
Leaves smail, entire, oval, obtuse, rounded to a short petiole, penninerve ; secondary 
nerves closer toward the base, the upper ones distant, simple, acrodome. 
We have only the two fragments figured, representing leaves five to 
six centimeters long, and three centimeters broad in the middle. They 
are nearly exactly oval, the base joing the short petiole by an imward 
curve. The three lower pairs of secondary veins are close to each other, 
half a centimeter distant, while the fourth pair is more than double that 
distance from the third. They are all simple or without branches, either 
alternate or opposite on the same angle of divergence of 40°, joined 
by thin nervilles in right angle, and following the borders in simple 
curves. 
The characters of nervation are the same as in the species of Cornus 
of the North American flora. By considering them only, we could refer 
these leaves to C. alternifolia, L., common over the eastern slope of the 
United States. Its leaves, generally acuminate, are sometimes rounded 
at the summit, like that of Fig. 1, by the splitting of the lamina and the 
incurving of the sides. There is, however, a difference in the base of the 
leaves which in the living species is generally narrowed and slightly 
tapering to the petiole. The rounded base is observable upon the leaves 
of @. Mas, U., of Europe, and @. sessilis, Torr., of California, both of the 
same section as the fossil ones.

Cornus Kelloggii, sp. nov. 
Pl. VI. Fig. 8. 
Leaves large, entire, broadly oval or nearly round, contracted upwards into a short 
acumen, narrowed by a curve to the base; secondary veins few, opposite, campto- 
drome ; nervilles strong, simple, distant, continuous. 
This fine leaf, about fourteen centimeters long (the lower part is broken), 
ten and a half centimeters broad, has characters very similar to those 
of Cornus Nuttall’, Audub., of California. In the living species the lateral
