Three hundred million years ago, ferns dominated the earth's surface, forming extensive marshes and forests with heights of over twenty-five meters. Today, ferns and their allies are still abundantly represented in the plant world, with somewhere between 10,000 and 12,000 species identified and recognized. These nonflowering, nonseeding, highly vascular plants make up a major and ancient division in the plant kingdom called Pteridophytes. In the state of Pennsylvania, one can find more than 100 species of these highly specialized plants. While ferns are by far the largest division of the Pteridophyte group in the state, horsetails, clubmosses, spikemosses, and quillworts are the lesser-known members, frequently misidentified as relatives of more modern flowering plants. With more than 190 color photographs and descriptions of 96 different plants, recognizing each Pteridophyte is a relatively easy matter. The photos of the plants show them growing in their natural settings, which helps to establish a clearer picture of the common characteristics of the families and their likely habitats. Maps illustrate the distribution of the various species throughout the counties of Pennsylvania and across the United States. Taxonomic keys are also included for each of the groups to assist in identifying the plants based on their biology. Finally, the book provides the most common local names for the plants, making it useful for both the amateur naturalist and the professional botanist.

This systematic treatment of the ferns and allied plants provides a modern classification of the Pteridophyta based on an assess ment of the wealth of new data published during the last few decades as well as on our own research. The accounts of the gen era include systematics, ecology, geography, spores and cytology and often other aspects of their biology. The scope of the work has involved all genera and the Old World species of those gen era represented in America. For a few American genera, that are especially complex in the Old World, it has been necessary to limit their treatment to the American representatives and this is specifically indicated in those cases. The eight American genera that do not occur in the tropics are treated in less detail. They are Camptosorus, Gymnocarpium, Matteuccia and Onoclea of North America, Arthropteris and Thyrsopteris of the Juan Fernandez Islands, Pleurosorus of southern South America, and the amphi tropical Cryptogramma. The complete generic nomenclature is included, except in a few specified cases where taxonomic complexities of the Old World elements have not been resolved. The synonyms and ac cepted names of subgeneric and sectional taxa are included only when pertinent to the generic nomenclature or to an infrageneric classification. Only the name of a publishing author is cited. There is no bibliographic purpose served by including the name of a person who was the source of, but did not validly publish, a name or epithet.

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.
