Book excerpt: Excerpt from Flora of Northeastern Pennsylvania In accordance with the expressed wish of the late Doctor Ever'hart, as a supplement to the collection of woods and seeds of Lackawanna County, which he was making at the time he was stricken with his last illness, labeled and now on exhibition in the Museum, I presented my Herbarium of over specimens to the institution which bears its founder's name. Incorporated in the Herbarium is a practically complete collection of the Flora of this part of the state, particularly of Lackawanna and Luzerne Counties. In further carrying out the wishes of Doctor Everhart I have prepared this check list of the Flora of the above region for publication. A preliminary list of the plants in the Lackawanna and Wyoming Valleys, of which Prof. W. R. Dudley, then of Cornell University, was the author, was published under the auspices of the Lackawanna Institute of History and Science, in 1887. This volume named 769 species as reported and classified. In 1892, Professor Dudley, then connected with the Leland Stanford Uni versity of California, and Prof. Charles 0. Thurston of the Wyoming Seminary Scientific Department combined their per sonal notes, observations and collections with those of other students of local botanical research and issued a very complete catalog of The Flowering Plants and vascular Cryptogams found in and near the Lackawanna and Wyoming Valleys. This volume contained the names of 107 orders and 974 species, to which there were later addenda of 88 species, - a total of Of this number several have since been considered doubtful, while others have become exterminated through forest fires or advance of cultivated areas and are not represented in this check list. The check list herewith presented contains the names of 115 orders and species. The specimens have very largelybeen collected by myself, mounted and preserved in the Alfred Twining Herbarium in the Everhart Museum. With few exceptions every plant named in this Flora is represented in the above Herbarium. There is also in this Herbarium a col lection of Filices and fern allies, - an almost complete representa tion of the ferns of the United States, and many foreign ferns with rare and odd varieties and forms. The Orchidaceae, Liliaceae and Violaceae of the eastern half of the United States are largely represented as well as the Cyperaceae and Gramineae. The classifications of the more important genera have been veri fied by such expert authority as Prof. Charles S. Sargent, the late Dr. Thomas C. Porter, the late Dr. Thomas Morong, the late Prof. James A. Graves, and Prof. E. Brainerd. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
