Preface In accordance with the expressed wish of the late Doctor Everhart, 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 2,000 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 V^alleys, 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 O. 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 1,062. 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 1,534 species. The specimens have very largely 7 been 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. Outdoor recreation being a necessity, as well as a great pleasure, I began late in 1900 the collection of the flora over practically the same range of territory covered by Professors Dudley and Thurston, as well as amateur collectors reported in the 1892 Flora. In preparing the appended list of plants I have followed the classification and nomenclature of the seventh edition of Gray's Manual. The plants recorded in this Flora which are not represented in Gray's Manual are marked with a star and the proper authority is indicated. In the revision, preparation for publication, proof-reading and effort to have the check list as nearly correct and authoritative as possible, I have had the kindly and generous assistance of Prof. R. N. Davis, Curator of the Everhart Museum, whose love of the woods and plant life first led me to the study and collection of our local flora. Alfred Twining. INTRODUCTION A flora of 1,200 species in a limited area is considered rich ; when 334 species are added to this number there is cause for wonder to botanists not familiar with the topography of the country from which the local flora has been collected and preserved in the Herbarium in the Everhart Museum. The heart of the Northern Alleghenies, where the tributaries of the Susquehanna, Lehigh and Delaware Rivers have their rise, is a beautiful country with a variety of soil and varying altitudes. We have many lakes, creeks, tangled swamps and bogs, dry barrens, rocks, valleys, plains and mountain peaks, with drift heaps of the glacial age. This varied topography affords local characteristic types as well as the plants common throughout the Appalachian region. On Bald Mount, Elk Hills, Penobscot, Pocono and Tilbury Knobs, and the Pocono Plateau and marshes we have rare plants of the glacial age. We have Atlantic slope species whose western limits of distribution are within our border as well as Southern and Southwestern species which extend no farther north or northeast. Over fifty-five northern species, mainly heaths and sedges, are found here which do not extend south of our territory. Among the more notable species included in our flora, and represented in the "Alfred Twining Herbarium," are the Arce- uthobium pusillum, Potentilla tridentata, Linnaea borealis, Vac- cinium canadense, Opuntia vulgaris, Picea mariana, Menyanthes trifoliata, Liatris scariosa. Ledum latifolium, Rhodora canadense, Andromeda polifolia, Kalmia glauca. Rhododendron viscosum Gaylussacia frondosa, Chiogenes hispidula, Orontium aquaticum, Melanthium latifolium, Amianthium muscaetoxicum, Arenaria groenlandica, Cunila mariana, Pinus inops, Sedum roseum, Asplenium montanum, and Lycopodium selago. While the leguminous species are rare on the Pocono they are abundant in the two valleys. Quite a number of plants which predominate in the country immediately outside the Lackawanna g Valley are quite rare or entirely lacking in the valley. Among these are teasel, hepatica, dicentra, claytonia, bloodroot, barberry, walking fern and some of the violets. A number of Southern and Western species have of late years been introduced in this region through the railroads. Weeds that were rare in Lacka- wanna County are now becoming pests. Prof. C. S. Sargent, Director of the famous Arnold Arboretum, a world authority on trees and shrubs, after three botanical visits to Scranton, expressed the opinion that there are at least forty species or forms of the Crataegus (hawthorn) in the Lackawanna Valley. Professor Sargent has classified twenty-seven of these, giving the handsomest of our local species the name of Crataegus twiningi. This species, an Intricatae, is described at length in the proceedings of the Academy of Natural Sciences of Philadelphia, Vol. LXII, Part I, 1910, pages 230 and 231. Professor Sargent adds to the description: "This species is named for its discoverer, Mr. Alfred Twining of Scran- ton, who first called attention to the richness of Lackawanna County in forms of Crataegus." The following interesting points and altitudes from which the greater part of the Flora in this check list was gathered are : The beautiful double domes of the Elk Mountains (south dome 2,575 feet, north dome 2,700 feet), exceeded only a few feet by the Blue Knob, the highest mountain in the State ; Bald Mount, 2,385; Clarks Summit, 1,239; Elmhurst, 1,397; Moscow, 1,555; Gouldsboro, 1,890; Tobyhanna, 1,929; Ararat Summit, 2,023; Uniondale, 1,693; Carbondale, 1,079; Archbald, 965; Pittston, 573; Kingston, 550; Crystal Lake, 1,755; Campbell's Ledge (Dial Rock), 1,302; Penobscot Knob, 2,220; Pocono Knob, 2,225; Ararat Peak, 2,600; Sugar Loaf, 2,450; Mount Anonymous, 1,596; Scrub Oak. 2,092; Big Shiney, 2.320; Moosic Mountain Range, from 2,000 to 2,120.
