DUDLEY, CoRNELL UNIVERSITY LIBRARY NEW Y¢ dk K BOTANICAL ne *% PI ae Se aN . ® ioe Cp. <3: ~ - ihe ar S55 P Coe cy INTRODUCTION. This list is preparatory to the systematic work of explora- tion, of collecting and preserving specimens of the living plants of the entire region, which is contemplated by the botanists of the Lackawanna Institute. Using this as a basis, - something that approaches a complete flora of the two valleys may be gradually elaborated; but several years of active work on the part of all the botanical members must elapse before such a catalogue would be sufficiently complete for publi- cation. The writer was a guest of the members of the Institute during a part of the session of their summer class in geology under Professor BRANNER in June, 1886; and at their suggestion, but unfortunately only a short time before his departure, he planned this paper. To make it in some sense worthy of its object he extended his researches for several additional days to certain parts of the adjacent plateau known as ‘ The Pocono,’”’ and in the autumn visited many parts of the Wy- oming Valley and the lower Lackawanna Valley; he also sought to bring together all the facts possible to obtain from others. This list, therefore, incomplete though it is even in respect to common plants, is based on information from sey- eral sources :— First—A collection of herbarium specimens, chiefly from these valleys, made by Mr. R. N. Davis, of the Archbald High School, to which were added some notes of observations, which were prepared with much care, and with an evident sense of the scientific value of accuracy of statement. His collection contained over two hundred named species of flow- ering plants and ferns, beside quite a number of unnamed 32 Lackawanna Institute. but interesting species. The work of Mr. DAvis has been of great service, and I have often given his name a place on the following pages, because of the indisputable evidence his specimens afforded me. Second—Notes of observations which were generously sent me by Professor THoMAS C. PORTER, of Lafayette College, Easton, Pa., who is the best authority on the plants of his State. Besides his ‘‘Sketch of the Botany of Pennsylvania,’’ published in Gray’s Atlas, 1872, he forwarded selections from lists of plants observed on ‘‘The Pocono’”’ and elsewhere in 1881 and 1884, also other notes of much value. In return I hope the botanists of the ‘‘ Northern Anthracite Coal Valley ”’ may be able to aid him essentially in the preparation of his forthcoming Flora of Pennsylvania. Third—Lists of plants observed by Mrs. BEEBER and Mrs. BvuELL, of Scranton, and Miss BANNISTER, of the Wyoming Seminary at Kingston, were placed in my hands, although they had no collections of pressed plants. Fourth—The present Director of the Arkansas Geological Survey, Professor JOHN C. BRANNER, who is the authority on the topography of these valleys, gave me many valuable hints as to interesting localities, and accompanied me on sey- eral excursions. Fijth—I have had my own collections and observations made during a week’s stay in Scranton and on the Pocono in June, 1886; also in the exploration in the Wyoming Valley in the autumn. Quite full notes were taken down at the time, and the more interesting plants preserved in my herbarium: The plan of the catalogue is as follows :—(1) All references to localities are for the Lackawanna and Wyoming Valleys and the mountains immediately bounding them. Because of their interest and proximity those plants we know to occur on the Elk Mountain (the highest point in N. E. Pennsyl- vania), and those at Tobyhanna, Gouldsboro, Lehigh Pond (near Gouldsboro and the source of one branch of the Lehigh River), Moosic Lake and other places on the neighboring Pocono plateau are included. ‘‘Common’’ means common over the areas of the valleys. (2) If a species is apparently Proceedings and Collections. 33 rare, or if it has not been observed in more than two or three stations, the stations are recorded. Otherwise ‘‘com- mon,’ ‘‘frequent’’ or other expressions to indicate abundance are used. (8) All statements of localities, for a species or of its abundance, not followed by any name of a person, are based on the writer’s own observations or collections. (4) If the name of a person follows any statement in the same sentence with it, it indicates that such person alone is au- thority for the statement. (5) References are frequently made to specimens in collections because such evidence is of the first importance. I would strongly urge every botanist of the valley to hereafter press all plants collected (certainly all those which are supposed to be at all rare), and place dupli- eates of them in the general herbarium of the Institute, for the use of future workers on the geographical distribution of species. Geologically the Lackawanna and Wyoming form one long, closed valley, and its mountain-walls gradnally coalesce at each end to become a single range. Because of the south- eastern curvature of both of these ranges,—the Moosic on the southeast and the Lackawanna on the northwest,—it presents, on the map, almost the form of a crescent. Through the walls of Lackawanna Mountain the Susquehanna River has broken, and passes into the valley at Campbell’s Ledge; then out of it, skirting the precipitous base of the River Mountain; then quite across the valley at Mocanaqua, and out again. This affords bold cliffs near a river, always favor- ite haunts of rare plants. Campbell’s Ledge, above Pittston, at the upper gateway of the Susquehanna, rises abruptly 750 feet above the river, and over 1300 feet above tide. We find the Walking Leaf Fern and the Cliff Brake (Pellea atropur- purea) on its summit, together with a rare flax (Linum sul- catum), and a still rarer grass (Keleria cristata). The latter also occurs on the River Mountains. Several miles northeast- ward from Campbell’s Ledge occurs the highest point of the Lackawanna range—Bald Mountain. It is easily reached by a good mountain-road from Scranton, and has an elevation of 2385 feet above tide. On its bold parapets of conglomerate Lr 5 34 Lackawanna Institute. grow the rare fern Asplenium montanum and one plant known nowhere else in the State, viz.: Potentilla tridentata. East and southeast of Scranton the Moosic range rises grad- ually into and partly coalesces with the broad plateau—the Pocono Mountain, which sweeps away to the east, northeast and southeast with a general elevation in this region of from 1800 to 2100 feet. This is naturally a wilderness area, much of it rocky or barren, and in it occur numerous swamps, peat- bogs and cold mountain ponds, which are sources of the brooks which feed the Delaware, the Lehigh, the Lack- awanna and the Susquehanna. Here occur occasional tracts— all too few at the present day—of the primeval forest, their dark, cool shades lighted up by the torches of Rhododendron flowers in June and July. I have particularly in mind Le- high Pond, surrounded by a sphagnum bog, and a large tract of the virgin forest. In the cold sphagnum are the heaths, orchids and sedges of Labrador and Northern Europe, here almost on their southern limit. Such are: Kalmia glauca, Ledum latifoliwum, Andromeda polifolia, Carex limosa, Carex Magellanica and Eriophorum vaginatum. In the half-light of the forest bordering, on the crumbling trunks of fallen trees, under tall pines, spruces and fragrant balsams, spring the pink Oxalis, the odd Indian-cucumber, the Pappoose-Flower (Trillium erectum) and dusky orchids like Habenaria orbicu- lata, Habenaria Hookeri, the Coral-root and the pink Moc- easin-flower (Cyprepedium acaule). All of this is in delight- ful contrast with the areas outside, desolated by the axe and the saw, and now exhibiting only ghastly dead trunks, oc- easionally left standing, the bare rocks and intervening wastes covered chiefly by Red Raspberry and Blackberry bushes, the Wild Red Cherry and the Bristly Elder. In sev- eral localities in the ponds on the Moosic and Pocono, as well as in the valley, occurs Orontium aquaticum in abund- ance, supposed to be a coast plant, but extending, according to Professor PORTER, far into the Alleghenies, even 300 miles from the sea. At the head of Little Roaring Brook on the Moosic Mountain, near Tobyhanna on the Pocono, and prob- ably elsewhere, occurs perhaps the most interesting species of a Proceedings and Collections. 35 the fora. It is Arcenthobium pussillum, a little plant allied to the true Mistletoe, and hitherto not discovered outside of the State of New York. It is parasitic on the branches of the Black Spruce of the mountain swamps. It is a curious fact that it was not even known to science until 1871, when it was discovered by Miss L. A. MILLINGTON in Warren County, New York. Since then stations have been discov- ered in Essex, Renssalaer, Saratoga, Herkimer, Oswego, and Sullivan Counties of New York, last year by myself in Seneca County, New York, and Lackawanna and Monroe Counties in Pennsylvania. It may be looked for farther south, as the Black Spruce extends into North Carolina, and there is no reason to suppose it affects the North like so many of the plants about it. Nevertheless this plateau, in its un- disturbed tracts, is remarkable for the predominance of north- ern plants, some of which find here their southern limits, some extend along the Alleghenies in a narrowing belt to their southern termination in North Carolina. In striking contrast to what has been mentioned above are the low, nar- row valleys, 500 to 700 feet above tide, such as the lower part of the Lackawanna and the more alluvial Wyoming. The richer soil, the sheltered areas and the shores of a river afford an entirely different series of plants. The Cottonwood, the Silver Maple, the American Elm are frequent here, with oc- easional Black Walnuts. Here also, along the river banks, is a characteristic and picturesque tree, with a rich, salmon- colored bark—the River Birch (Betula nigra). It forms groves along the Susquehanna, and Everhart’s Island, on the lower Lackawanna, is nearly covered with a fine growth of them. They have been noticed above Scranton to Peckville, but prob- ably disappear with the changed character of the valley above Archbald. The Wild Yam is occasional in the Lackawanna and Wyoming Valleys, and where the Susquehanna breaks across at Mocanaqua, occurs Dianthera, a plant of the larger river and lake shores, conspicuous on the lower Susquehanna and the lower Juniata, but not known on the Delaware or its branches, or hitherto on the upper Susquehanna. Here also is Physostegia Virginiana, a handsome flowered western plant, ee ce sD 36 Lackawanna Institute. this station apparently being on its northeastern limit. It is rare in Pennsylvania, Professor PoRTER reporting it on the Schuylkill below Norristown (its extreme eastern limit), and as sparingly on the Jower Susquehanna. Near Moca- naqua occurs Hrysimum cheiranthoides, hitherto regarded as peculiar to the Susquehanna below Harrisburg. Outside the valley proper are localities of presumable in- terest to the botanist, because of their height and exposure; and they are near enough to be readily visited from Scranton, but it is doubtful whether they will yield as much that is of interest as the places already mentioned. Elk Mountain, ten miles northwest of Carbondale, has two peaks, the South Knob, 2575 feet, the North Knob, 2700 feet above tide. A single visit to this mountain in June revealed but few rare plants. Panicum xanthophysum, between the knobs, may be justly called so. It is not reported south of Luzerne County, and occurs but sparingly from Massachusetts to Minnesota. Sixteen miles north of Carbondale are Ararat Peak, 2600 feet, and Sugar Loaf, 2450 feet above tide. These have not been visited by myself. The illustrations given indicate that our limits include many rare plants and a very great variety of soil and hab- itat; and yet it will be seen that explorations have been both hasty and incomplete. The promise is clearly great for the discovery of as interesting forms as any yet found, and there is, therefore, every incentive to this fascinating work for those who can carry it forward. Let everyone interested make it a point to press the plants secured, even the common ~ ones; and let duplicates of each species, accompanied by a label giving exact date and locality,—even if the name be omitted,—be placed in the hands of a curator appointed by the Institute. From these labels a slip catalogue could be easily made and kept by the curator, and he could direct future searches for plants which ought to occur within limits, but which have not been secured. In doing this it would be wise to assign particular orders of plants to individuals and make each responsible for work done in collecting the species belonging to such orders. Let each specimen pressed be as j : : ‘ 1 § 1 ( lt i i a 4 mr va Thi be r i. dy oti i, ae * ms : RAP ARE foe rete may H ' a re } a vat ¢ uel oe ee an - : an yeh ae we! ’ | Proceedings and Collections. 37 ve oti in the case of herbs, as it is possible &é disk’ oes let the specimen be cared for while in press so that lors shall comie out as bright and as natural as it is ie to make them.

With such CO- oper rat ion and care results can be accomplished which may of much use to science. | ike sa -/, = ‘ANICAL LABORATORY, Cor l University, June 1, 1837.
