PREFATORY NOTE.

Office of United States Gteological and Geographical Survey of the Territories,

Washington, January 1, 187 B.

A small edition of five hundred copies of the accompanying plates of fossil plants, from the Cretaceous and Tertiary strata of the Western Territories, is issued at this time for the use of botanists in this country and innbsp;Europe. These plates, twenty-six in number and twenty-five hundrednbsp;copies of each, have now been engraved and printed for a period of sevennbsp;years, awaiting the final report by Dr. J. S. Newberry. The greater portionnbsp;of the species have been described in an article in the Annals of the Lyceumnbsp;of Natural History of New York, read April 22, 1867, and published innbsp;April, 1868, entitled “ Notes on the Later Extinct Floras of North America,nbsp;with descriptions of some new species of Fossil Plants from the Cretaceousnbsp;and Tertiary strata”, to which the attention of the reader is referred. Thenbsp;fossil plants themselves form a portion of the collections that were madenbsp;by me during the earlier years of my explorations in the Northwest,nbsp;commencing in the spring of 1854. The Cretaceous plants are mostly fromnbsp;the Rusty Sandstones of the Dakota Group in Nebraska, while the Tertiarynbsp;were obtained from the Fort Union Group along the Upper Missouri andnbsp;Yellowstone Rivers.

I will not discuss the differences of opinion in regard to the age of the Tertiary plants in this connection. It is sufficient to state that up to 1870nbsp;they were admitted to be of Miocene age without dispute.

The names' and references were prepared by Prof Lesquereux, at my request, from a comparison of the descriptions with the figures, and also bynbsp;examination of specimens of a number of the species preserved in thenbsp;Museum of the Smithsonian Institution. Should the text, which wasnbsp;intended to form Vol. VIII of the quarto series, never appear, these platesnbsp;will nevertheless not be entirely 'lost to science.
