V-6. Reference should also be made to the extensive researches of Newberry upon the tertiary and cretaceous floras of the Western United States. See especially Prof. Newberry’s paper in the Boston Journal of Natural History, vol. vii., No. 4, describing fossil plants of Vancouver’s Island, etc.; his “Notes on the Later Extinct Floras of North America,” etc., in “Annals of the Lyceum of Natural History,” vol. ix., April, 1868; “Report on the Cretaceous and Tertiary Plants collected in Raynolds and Hayden’s Yellowstone and Missouri Exploring Expedition, 1859—1860,” published in 1869; and an interesting article entitled “The Ancient Lakes of Western America, their Deposits and Drainage,” published in The American Naturalist, January, 1871.
The only document I was able to consult was Lesquereux’s “Report on the Fossil Plants,” in Hayden’s report of 1872.
V-7. There is, at least, one instance so opportune to the present argument that it should not pass unnoticed, although I had overlooked the record until now. Onoclea sensibilis is a fern peculiar to the Atlantic United States (where it is common and wide-spread) and to Japan. Prof. Newberry identified it several years ago in a collection, obtained by Dr. Hayden, of miocene fossil plants of Dakota Territory, which is far beyond its present habitat. He moreover regards it as probably identical with a fossil specimen “described by the late Prof. E. Forbes, under the name of Filicites Hebridicus, and obtained by the Duke of Argyll from the island of Mull.”
