Mr. L. F. Ward on Mesozoic Dicotyledons. 387 
In 1866 appeared the somewhat famous “ Phyllites créta- 
cées du Nebraska” of Capelliniand Heer*, the latter of whom 
determined the fossil plants which the former had himself 
helped to collect at Blackbird Hill, Nebraska, in the now 
well-known Dakota group. The Cretaceous character of these 
fossils was here rather grudgingly conceded, and has never 
since been seriously doubted. 
While America had been thus coming forward Europe had 
remained in the background for about ten years, or since 
Stiehler’s monograph of the Harz in 1857. It was not till 
1867 that Ettingshausen ft published in the ‘ Sitzungsberichte’ 
of the Vienna Academy his valuable paper on the fossil flora 
of Niederschéna in Saxony. The horizon of this place is con- 
siderably lower than that of Blankenburg, and belongs at the 
base of the Quadersandstein formation of Germany. Never- 
theless, the species nearly all belong to living genera 
Quercus, Fagus, Ficus, Laurus, Protea, &c. ‘Twenty-eight 
species are enumerated. 
In the same volume Unger f{ described and figured four 
Dicotyledons, thus far unknown, from the Gosau (Upper 
Senonian) of Austria, at St. Wolfgang and Neue Welt. 
Though contenting himself with calling them all Phyllites, he 
yet ventured to assign two of them to the Magnoliacez and two 
to the Proteacez. 
Returning to America, we find in 1868 the two most 
important contributions yet made in this country to the Cre- 
taceous flora of the west. ‘These were Dr. Newberry’s “ Notes 
on the later extinct floras of North America,’ published in 
the ‘ Annals of the New York Lyceum of Natural History’ 
(April) §, and Mr. Lesquereux’s paper in this Journal || for 
July of the same year. Though prepared quite independently 
of each other, these two papers followed the same method and: 
reached the same results. Both authors give lists of the 
American Cretaceous species known up to that date, Dr. New- 
berry enumerating 20 and Mr. Lesquereux 21 Dicotyledons.
