LANSING, MICH. ROBERT SMITH PRINTING CO., STATE PRINTERS AND BINDERS 1904 ?o4 INTRODUCTION, The first Michigan Flora entitled a "Catalogue of the Phaenogamous and Vascular Cryptogamous Plants of Michigan, Indigenous, Naturalized and Adentive," was prepared by Charles F. Wheeler and Erwin F. Smith, and was printed in the report of the Michigan State Horticultural Society for 1880. The second Michigan Flora, based on the first, was prepared by W. J. Beal and C. F. Wheeler and was printed in the report of the Michigan State Board of Agriculture for 1892. Of the second Michigan Flora one thousand separates were printed, for distribution and the supply was exhausted in less than five years. The copies of all the former edition of this Flora were distributed chiefly among botanists of all grades from Professors in Universities and Colleges, Normal Schools, teachers in High Schools, Academies and among amateurs. It is believed that this edition notwithstanding all its defects, will encourage many to study the wild plants of Michigan not forgetting the arrivals from other countries. Besides assisting the student in becoming familiar with names of species and their distribu- tion, it should be useful in other respects. Within the past few years a delightful department of botany has attracted much attention. It is emphatically outdoor work and is known as Ecology or the relations of plants to their environment. This Flora may help the student in his investigations of plant groups or plant associations, noting those peculiar to certain kinds of soil, and others growing almost everywhere. It will aid in listing natives and exotics. Students can make many lists, such as those forming rosettes, those that climb, those that thrive in the woods in early spring, those that grow in strata or layers above each other or in zones within and without each other. It should aid in the study of plant dispersal by all sorts of methods and in the multitude of ways by which plants protect themselves. The following is a list of the chapters found in the last edition of the Flora that are omitted in this edition : Planting the Roadside and about the Home. Planting a Grove. Planting a Wild Garden. Autumn Foliage. Native Tr^es and Shrubs selected for the Color of their Leaves in Autumn. Native small Trees and Shrubs distinguished for their Flowers.

As mentioned in both editions of the Flora above referred to, so in this, the third edition, much pains has been taken to examine authentic specimens which are preserved in some herbarium. For thirty years, till he resigned his position at the Agricultural College in 1902, Professor C. F. Wheeler was a most diligent collector of plants in the State. He kept full notes, not only of his findings but sought specimens and notes from many others. In 1888, Professor L. H. Bailey, C. F. Wheeler, and the author accom- panied by two students spent two weeks in collecting on a journey across the State from Harrisville in Alcona county to Frankfort in Benzie county. In 1892, Professor Wheeler spent several weeks in the southeastern and in the southwestern counties and in the Upper Peninsula making collections for the exposition held in Chicago. In 1895, some weeks were spent collecting in Alpena and vicinity, and later he and B. O. Longyear collected in Ingham. Washtenaw, and Jackson counties. In the summer of 1900 Professor Wheeler spent about six weeks collecting at Chatham and vicinity in the Upper Peninsula. Portions of every year since 1890 were occupied by Professor Wheeler in making great numbers of short excursions in behalf of the herbarium of the Agricultural College. During these years and previously, the author collected considerable in the counties of losco, Clare, Crawford, Grand Traverse, Lake, Muskegon, Calhoun, Eaton, Lenawee, Clinton, Ingham. More particularly since 1890, numerous collections made by others have been sent to the Agricultural College for identification and for preservation in the herbarium. Notably among these collectors must be mentioned Miss Emma J. Cole BEAL ON MICHIGAN FLORA. 'and H. C. Skeels of Grand Rapids; C. D. McLouth of Muskegon; G. H. Hicks of Grayling, Owosso and the Agricultural College; C. K. Dodge of Port Huron; George M. Bradford of Bay City; W. K. Brotherton of Oakland; Geo. W. Davis of Tekonsha; J. W. Stacy of Clarksville. Col- lections have been received, by gift or purchase, from Prof. C. A. Davis formerly of Alma, now of the University; of O. A. Farwell formerly of Keweenaw county, of Ypsilanti, and later of Detroit; and Rev. Francis Daniels formerly of Alto, Kent county, Manistee and Sturgis; W. S. Cooper of Alma. After all has been said and done, the study of the flora of the state at • best can only be considered as fairly begun. By far the greater areas have not yet been seen by any systematic botanist and very few regions have been visited by one who is an expert in some one or more of the more difficult families. What species flourished in large areas will never be fully known, since man has cut off, burned over and plowed under tens of thousands of acres of the virgin wilderness ! Swamps, marshes and lakes have been drained and the land occupied by farm crops. Many native plants are rapidly shifting from one place to another. Chiefly through the agency of man, great numbers of weeds and other plants have been introduced from other states and from foreign countries and each* has begun a vigorous warfare for all the room it can get. The sequence of natural families in former Michigan Floras followed Gray's Manual which is essentially that of Auguste Pyrame De Candolle. Most of the reasons given for that arrangement have long since been considered untenable. In the Flora, I have followed Britton's Manual of the Flora of the Northern States and Canada, published in April, 1901. In this work the sequence of families is very nearly the same as that of Engler and Prantl, which is considered the most philosophical yet pre- sented. Some of the guiding principles for the system of Engler and Prantl, as they are stated by Britton and Brown's Flora, are as follows: The more simple forms are, in general, distinguished from the more complex, (1) by fewer organs or parts; (2) by the less perfect adapta- tion of the organs to the purposes they subserve; (3) by the relative degree of development of the more important organs; (4) by the lesser degree of differentiation of the plant-body or of its organs; (5) by con- siderations of antiquity, as indicated by the geological record; (6) by a consideration of the phenomena of embryogeny. Thus, the Pteridophyta, which do not produce seeds and which appear on the earth in Silurian time, are simpler than the Spermatophyta ; the Gymnospermee in which the ovules are borne on the face of a scale, and which are known from the Devonian period onward, are simpler than the Angiospermre, whose ovules are borne in a closed cavity, and which are unknown before the Jurassic. In the Angiospermse the similar types are those whose floral structure is nearest the structure of the branch or stem from which the flower has been metamorphosed, that is to say, in which the parts of the flower (modified leaves) are more nearly separate or distinct from each other, the leaves of any^stem or branch being normally separated, while those are the most complex whose floral parts are most united. The names of genera and species are tfre same as those used in Britton's Manual and where these differ from those in the sixth edition of 6 MICHIGAN ACADEMY OF SCIENCE. Gray's Manual, the latter are also inserted in the text. The species of each genus are arranged in alphabetical order. To economize space a considerable number of sections of the Flora last prepared have been omitted or much abbreviated. , In the preparation of this Flora thanks are due to Professor C. F. Wheeler, O.

The following Herbaria have been examined: The Herbarium of the State Agricultural College is fortunate in pos- sessing the collection of Dr. D. Cooley, an excellent botanist who lived many years in Washington, Macomb county. He was a valued correspond- ent of Dr. Gray, Dr. Torrey, W. S. Sullivant and other botanists of the early part of this century. The Herbarium of Dr. D. Clark, of Flint, Mich., has lately become the property of the State Agricultural College. This collection contains sets of Bebbs' Willows, Olney's Carices and many specimens from the earlier American collectors, besides valuable collections of Michigan plants.

Michigan is peculiarly situated within the waters of the great lakes, N. latitude 41°45' to 48°20'; W. longitude 82°25' to 90°34'. It is divided into two parts, called the Upper and Lower Peninsulas. The greatest length of the northern portion from east to west is 318 miles, width 30 to 12 MICHIGAN ACADEMY OF SCIENCE. 164 miles, forming about two-fifths of the State. The greatest length of the southern portion from north to south is 277 miles and its extreme width is 259 miles. The total area is 58,915 square miles, with a coast of over 1,600 miles. The general elevation of the Upper Peninsula is 400 to 1,100 feet above Lake Superior, and that of the Lower Peninsula is 400 to 600 feet above the level of Lakes Michigan and Huron. The two parts of the State present a striking contrast in many respects. The Upper Peninsula may be divided into two sections east and west of a line drawn through Marquette which present very marked surface and geological characteristics. The eastern portion slopes northward from its southern border to a watershed and thence falls rapidly to the shores of Lake Superior. This plateau contains many lakes and marshes, also fine forests of pine intermixed with groves of hardwood. The western part is rugged and hilly, some of the hills rising 1,000 to 1,200 feet. In the extreme northwest are ranges which form the copper region; the central range extends from Keweenaw Point across to the Wisconsin line; on either side are the Porcupine mountains and the copper range proper. South and east of the copper range lies the iron range of Marquette and Iron counties. The eastern portion of this peninsula is underlaid writh stratified rocks belonging to the Silurian period, while the western part is occupied by the copper bearing rocks and those of the Huronian period. Glacial drift covers deeply a large portion of both the eastern and western sections. The Lower Peninsula is generally level or rolling, sloping up in its northern portion to a central ridge or watershed which extends nearly northeast and southwest, the highest part .of which, in Otsego county, is 1,100 feet above the lake level. The shores along the west side of this peninsula are generally bold bluffs which are constantly wearing away, while on the Huron shore they are low and extending by additions of earth cast up by the waves. The rivers are small but their number is great, and these, with the 5,000 lakes scattered along the watersheds of the State abundantly water all parts of it. Dr. C. Kominger, a former State Geologist, writes of the geology of the Lower Peninsula as follows : "It forms the center-point of an oceanic bay which seems to have existed without any important alteration* in its limits, from the beginning of the Silurian period to the end of the Carbon- iferous time. We find within the space supposed to have been the bay an uninterrupted series of marine deposits, following each other in the great- est regularity of superposition, which represent all the known formations deposited on this continent from the Silurian period on to the coal forma- tion." The entire surface of the peninsula is covered deeply with glacial drift, consisting of sand, gravels and clays variously intermixed. The topographical outlines of the Lower Peninsula are due to the joint action of moving ice and flowing water during and following the glacial period. Beginning in Presque Isle county the lateral moraine of the Huron glacier passes southwest near the line between Montmorency and Alpena counties, thence south by west through Oscoda, Koscommon and Clare, meeting in Mecosta county, the east lateral moraine of Lake Michigan. These join and pass in a southwest direction through Kent, Barry, Kala- BEAL ON MICHIGAN FLORA. 13 mazoo and St. Joseph counties. The Saginaw bay branch of the Huron glacier unites with the Huron glacier proper, and forms a lateral moraine beginning in Huron county, passing through Sanilac, Lapeer, Oakland, Livingston and portions of Jackson, Washtenaw and Hillsdale counties. This peninsula is divided by these moraines into certain more or less clearly marked floral regions. CLIMATE AND DISTRIBUTION. "The sinuosities of the several isothermal lines will demonstrate at a glance the peculiar character of the climate of Michigan, and the fact that both in summer and winter, it is better adapted to the interests of agri- culture and horticulture, and probably also to the comfort and health of its citizens, than the climate of any other northwestern state. The marked peculiarity of the climate of Michigan in these respects is attributable to the influence of the great lakes by which the state is nearly surrounded. It has long been known that considerable bodies of water exert a local influence in modifying climate and especially in averting frosts, but it has never been expected that Lake Michigan, for instance, impresses upon the climatic character of a broad region an influence truly comparable with that exerted by the great ocean." — ALEXANDER WINCHELL. The following general notes on Climate and Distribution are from the preface to the first edition by E. F. Smith : "The influence of climate on vegetation may be summed up in a few words. The climate of the Lower Peninsula is not as severe as that of the Upper, nor so even, but is subject to frequent, sudden, and extreme changes of temperature — as great a variation during the winter season as 53° Fahr. in less than 24 hours having been recorded. Such rapid changes more or less affect vegetation, especially the tender branches of cultivated trees, which are sometimes seriously injured. In one or two instances a like effect on our forest trees has been noticed. The annual range of temperature is about 116°, and the annual mean 46°. Of rain- fall, including what falls in form of snow, we have, yearly, about thirty inches. Our snowfall is much less, for the same latitude, than that of New York and New England. In the center of the peninsula, wre seldom have more than a few inches at a time. "The proximity of the Great Lakes exerts a marked influence in equal- izing the temperature and the effects are marked upon our flora. "Trees, like Liriodendron Tulipifera, Asimina triloba, Ccrcis Cauaden- sis, Gleditsia tria'canthos, Cornus florida, Nyssa multiflora, and Morus rubra, which belong to Ohio and Central Illinois, have crept north ward, favored by the mild -influence of the lake winds, through the central and western- part of the Lower Peninsula, often beyond the middle, and the same is true of smaller and less noticeable plants. "As might be expected from the uniform surface of the peninsula, the flora is much alike throughout. Probably three-fourths of our species are common to all sections, though by no means equally distributed; some being very abundant in one district and rare in another at no great dis- tance. In most cases such change is due to soil rather than to difference in elevation, temperature, or atmospheric moisture. "The Lower Peninsula is covered with a deep drift of alternating sands, clays, and gravels, and the flora of any section depends chiefly on which of these happens to lie uppermost. With reference to its flora, the pen in- 14 MICHIGAN ACADEMY OF SCIENCE. sula may roughly be divided into two great divisions — the hardwood and the softwood lands; one representing the Appalachian flora, and the other, the Canadian. "The hardwood country lies south of latitude 43 °, and consists of very fertile sand, clay, or loam, mostly cleared of the original forest, and largely cultivated. "The sandy or stony drift of many river valleys in this section supports a heavy growth of oak, frequently interspersed with walnut and hickory, while the margins of the streams, and the neighboring swamps, abound in sioft maples, swamp and chestnut oak, white and black ash, elm, hack- berry, sycamore, butternut, and similar trees. Willows, dogwoods, vibur- nums, and buttonbush, are common shrubs in the swamps; and hazel, hawthorn, wild cherry and plum, June berry, witch-hazel, etc., are abund- ant on the dryer ground. "On the uplands, and away from streams, clay, loam, and a peculiar black muck soil supersede the sands and gravels of the valleys. The pre- vailing timber here is beech and maple and oak forest in about equal pro- portions. Beech and maple generally grow together, forming magnificent forests of great extent. The best wheat farms are usually found on uplands near streams, where the oak timber gradually shades into beech and maple. Plains of fertile sand covered with a low, or scattering growth of oak (oak openings) are frequent, and always very desirable for farming purposes. "Marshes densely covered with tamarack are common in this part of the State, and nourish in their thick shade such plants as Drosera rotundifolia, Sarracenia purpurea, Rhus venenata, Ribcs rubnun, Ohio- genes liispidula, Salix Candida, Smilacina trifolia, Pogonia ophiogtos- soides and Calopogon pulchellus. Arbor-vitae, red cedar and black spruce are comparatively rare. "A similar tract of soil and timber occurs in the upper end of the pen- insula, north of a line drawn from Thunder bay west to the head of Grand Traverse bay. This is commonly known as the "Traverse region," and has a flora much like that we have just described, with the exception that some of the southern species disappear, and northern ones begin to take their place, or if found growing further south, here first become frequent. Deep forests of hemlock and -yellow birch (B. lutca) mixed with a fine, tall growth of striped maple (A. Pennsylvamcum) are frequent, having underneath a tangled growth of Taxus baccata, var. Canadensis, and under all a carpet of Lycopodium annotinum. Alternating with these are sandy plains covered with a dense growth of Vacciniums, yielding a great abun- dance of fruit. Sugar maples and basswood are also abundant in this region, and reach an immense size. In fact, it would be difficult to find finer groves of maple in any part of the State. "The pine country proper lies between the two tracts we have described, and embraces about 15,000 square miles. It is composed largely of sand hills and plains, either scantily furnished with vegetation, or densely cov- ered with pine forest. Argillaceous tracts wooded with beech and maple also occur, like oases in a desert ; and swamps abound, with the usual low- land timber. Forests of hemlock spruce are frequent, and there are occa- sional ridges of oak. Birch (B. lutca} also begins to be a common forest tree, and attains a large size. The usual timber of the barrens is Jjick Pine (P. Banksiana). Climatic and other influences have combined to produce groves composed entirely of this species of large size and of great BEAL ON MICHIGAN FLORA. 15 beauty, for, instead of being 'a straggling shrub, or low tree' (Gray)? it rises, often 50-60 feet, straight and symmetrical. All through this region Pinus Strobus is the prevailing species and furnishes most of the lumber, but P. resinosa is frequent as far south as Clare county, and occurs sp.ir- ingly in the northern part of Isabella county, which appears to be its southern limit. "Such is the general character of the sylva down to about latitude 415°. but in the western part of the State, owing perhaps to moister climate, or to favorable soil, hemlock spruce is more abundant, and reaches much farther south, nearly or quite to the Indiana line, and the same is true of white pine. "The flora of the deep pine woods is interesting, though rather monot- onous. Very little undergrowth is found, and their gloomy recesses nourish only such plants as love thick shade. Here the club-mosses (Lycopodiums) find a congenial home, and flourish luxuriantly, while Clintonia borealis covers the ground. The great round-leaved orchid (Habenaria orbiculata) , with its tall, greenish spike and twin leaves close to the earth, is also frequent and striking. We shall also meet MitchcUa repenSj Maianthemum Canadense, Trillium grandiflorum, perhaps, and a few ferns, particularly Asplenium Filix-fcemina and Phegopteris Dryop- teris. Other species occur, of course, but not so abundantly. In more open places, and on ridges, we meet Rhus aromatica and Comptonia along with wintergreen (Gaultheria) and trailing arbutus (Epigcva), and are often fortunate enough to find the wax- white, fragrant flower of Monescs uniflora, or Polygala paucifolia, hiding its shining leaves under a wealth of showy pink blossoms. "The floral treasures of the pine region lie, however, in its swamps and lake borders rather than in the deep woods. Therein grows Linncea borealis in all its delicate beauty, carpeting the ground, and close at hand, the odd, brown-purple flower of Cypripedium acaule and the small yellow blossom of its water-loving relative C. parviflorum. In such swamps, or within a stone's throw of them, may be found many other plants of equal interest, such as Medeola Virginica, Ledum latifolium , Andromeda Poll- folia f Kalmia glauca, Lonicera oblongifolia, Cardamine pratensis, Ger- ardia aspera, Mitella nuda, Eriophorum vaginatum, etc. On lake mar- gins we shall find Lysimachia and ttie blue Pontederia and more rarely, Nesoea and Eleoclwris quadrangulata. The lake itself, most likely, will be full of Nymphaea, Nuphar, Utricularias, and a world of Potamoge- tons and similar water weeds. Shrubby Vacciniums line the bluffs, and here and there gleam the white trunks of paper birches against the dark background of pines. "In the thick-pine country, where the lumberman's ax has let in the sunlight, new plants spring up freely. Here, Primus Pennsylvania and poplars are frequent, and the blackberry is omnipresent. Aralia hispida and Physalis lanceolata are also peculiar to such land, and in August Gnaphalium decurrens may be seen whitening thousands of acres. "One seldom beholds a drearier sight than a dead and deserted lumber region. The valuable trees were all felled years ago, and the lum- berman moved on to fresh spoils, leaving behind an inextricably confused mass of tree tops, broken logs, and uprooted trunks. Blackberry canes spring up everywhere, forming a tangled thicket, and a few scattering poplars, birches, and cherries serve for arboreal life, above which tower the dead pines, bleached in the weather and blackened by fire, destitute of 16 MICHIGAN ACADEMY OF SCIENCE. limbs, and looking at a distance not unlike the masts of some great harbor. Thousands of such acres, repellant alike to botanist and settler, can be seen in any of our northern counties. "In certain districts considerable beech is found associated with the pine. The soil of such tracts is usually of better quality, and can be rendered productive without much labor. It may be noted that in such cases the pine also grows thriftier and makes better lumber." FLORA OF THE JACK-PINE PLAINS. The plants of this region are all found in one or more of the regions previously enumerated. The soil of these plains is mainly sand of considerable depth which dries out quickly after a rain, and is then especially liable to be burned over, the burning often destroying every living plant above the surface of the soil. In this way, by repeated burning, much of the vegetable matter is removed, leaving the surface soil thin. The following seventy species of plants are almost certain to be found in considerable quantity on any extended area of Jack-pine plains : a. THOSE MOST COMMON. Amelanchier Botryapium (L. f.) DC.

The above list consists of representatives of thirty families, of fifty- four genera, and of seventy species. The families of plants best repre- sented on the plains are the Rosacece by six species, Compositce by thirteen species, Graminece by nine species, Vacciniacece by four. The following large and prominent families of the State are not repre- sented in the list given above : Ranunculacece, Cruciferce, Caryophyllacew, Umbelliferce, Orchidacece. 18 MICHIGAN ACADEMY OF SCIENCE. Most remarkable of all is the absence of any Papilionacece though the family is second in size only to the Composite. The Papilionacece is represented in the State by 43 native species and varieties. The number of biennials given in this list is remarkably small, only two, and there are no annuals in it. Sixty-eight out of seventy are perennials and most persistent plants well adapted by long, deep roots and root- stocks to live in poor soil which is subject to severe droughts. Most of them are admirably adapted to survival after a severe fire has burned over the ground and killed the tops of the plants. PLANTS INDICATING A FERTILE SOIL. Acer Saccharum Marsh.

COMPARISON OF THE FLORA OF THE EASTERN AND THE WESTERN SIDES OF THE STATE IN THE LATITUDE OF 44°40'. On the east side, the latitude in question is near Harrisville in Alcona county. On the west side it is near Frankfort in Benzie county. It has long been known that the climate -of the west shore where the wind sweeps across Lake Michigan was milder in winter, and throughout the year less variable than it is on the east side of the State. So far as observed, the plants of the State which are only found in the vicinity of the great lakes are more abundant in individuals on the west shore. A.

This list is doubtless incomplete, but so far as it goes it sustains the pre- vailing notion that the west side of the State has the milder climate. We might be able to see why silver maple, sassafras, black raspberry, red elm and rock elm thrive on the west shore and not on the east, but we are unable to see why the northern plants found on the east shore should not be found on the west shore. Perhaps there is some other reason than the difference of climate of the present day. PLANTS SUPPOSED TO HAVE IMMIGRATED FROM THE NORTHEAST. Calypso bulbosa (L.) Oakes. (Calypso borealis Salisb.)

TREES OF MICHIGAN COMPARED WITH THOSE OF EUROPE. Michigan is very rich in trees. If we have counted correctly there are 90 species of indigenous trees and three exotics which have escaped from cultivation. To comprehend the relative importance of our trees, let us glance at the forests of Great Britain. Great Britain and Ireland contain 121,260 square miles of land, Michigan 60,000, a little less than one-half as much as Great Britain. She has one species of basswood not so good as ours ; one maple not over twenty feet high ; one cherry from ten to twenty feet high; one small ash, two elms, two poplars, one beech, which grows very large but not very high; one small white birch, one species of pine, by no means a match for our white pine; a species of oak which sometimes grows to a great size. Great Britain has about ten species of trees native to her soil. Michigan, with half the territory, has eighty-five species. Great Britain has no whitewood^ no white or red cedar, no walnuts or hickories. Michigan has six species of maple pf tree size, a basswood, a whitewood, honey locust, Kentucky coffee tree, three cherries, a pepperidge, five species of ash, a MICHIGAN ACADEMY OP SCIENCE. sassafras, three elms, a hackberry, a mulberry, a buttonwood, black wal- nut, butternut, eight hickories, thirteen oaks, a chestnut, a beech, four tree birches, three willows of tree size, five poplars, three pines, three spruces, one hemlock, a balsam fir, one larch, one arbor-vitae and a red cedar. In all Europe there are only 85 species of trees. WHY HAS MICHIGAN SO MANY TREES AND GREAT BRITAIN SO FEW. This question now very naturally arises : Why has the Atlantic region, including Michigan, so many species of trees and why has Europe so few? Certainly we cannot attribute this difference to a defective soil and climate of Europe, as they now exist, for Europe can grow all sorts of trees now found in the temperate zone, while "Great Britain alone can grow double or treble the number of trees that the Atlantic States can." The former geological conditions of their continents help to explain all this difference in the distribution of trees to the entire satisfaction of scientists. Away back in the Tertiary Period the trees of the regions now possess- ing an arctic climate were such as now thrive in a warm temperate zone like that of Georgia and California. This is well illustrated by the abundant fossil remains of trees. Following this, came a long time when extreme cold prevailed, known as the Glacial Epoch, when snow and ice for most or all of the year extended to the Ohio river. At the approach of cold, the trees slowly retreated southward, as generation followed genera- tion. The plants such as now thrive in southern Michigan, perhaps then extended to what now forms the State of Alabama, while the arctic plants reached Ohio. As the climate again gradually grew warmer, the trees and other plants slowly migrated northward. Some arctic plants were stranded on the White mountains and in Labrador, where they still remain; others went farther north. Plants of the cool temperate zone reached Michigan. In a similar man- ner, during the Glacial Epoch the plants of Europe were driven south- ward. The Alps, the Pyrenees, the Appenines, the Caucasus, still contain some of these arctic plants which retreated there at the close of the Glacial Epoch. Most of the plants of the warm temperate region had perished and therefore were unable to retreat when the continent became warmer. I quote the words of Dr. A. Gray, from whom other hints are taken, as found in the American Journal of Science, page 194, 1878. "I conceive that three things have conspired to this loss. First, Europe hardly ex- tending south of latitude 40°, is all within the limits generally assigned to severe glacial action. Second, its mountains trend east and west, from the Pyrenees to the Carpathians and the Caucasus beyond, near its southern border; and they had glaciers of their own, which must have begun operations, and poured down the northward flanks, while the plains were still covered with forest on the retreat from the great ice wave coming from the north. Attacked both on front and rear, much of the forest must have perished then and there. Third, across the line of re- treat of those which may have flanked the mountain ranges, or were stationed south of them, stretched the Mediterranean, an impassable barrier. • "Greenland may be referred to, by way of comparison, as a country BEAL ON MICHIGAN FLORA. 23 which, having undergone extreme glaciation, bears the marks of it in the extreme poverty of its flora, and in the absence of the plants to which its southern portion, extending six degrees below the arctic circle, might be entitled. It ought to have trees, and might support them. But since destruction by glaciation, no way has been open for their return. "In the American continent the mountains run north and south. The trees, when touched on the north by the on-coming refrigeration, had only to move their southern border southward, along an open way, and there was no impediment to their due return. So our lines have been cast in pleasant places, and the goodly heritage of forest trees is one of the consequences." NATIVE FORAGE PLANTS. The native grasses while young, from early spring to winter, without exception, furnish a tender bite which is very acceptable to all sorts of horses, cattle, sheep, and even swine and poultry. Most of the native grasses (about 120 in number) grow in isolated bunches, more or less fre- quent, and furnish but little food, while a considerable portion soon become unpalatable as the summer approaches. The most important native grasses for pasture or meadow are found in open places, and are : June grass (not native), fowl meadow-grass, and several other species of Poo, which have no well-known common name; several manna-grasses (Panicularia) ; a few small fescues, two or three Eatonias ; blue-joint, two or three small redtops, and several species of Muhlenberg's grass, two or three kinds of mountain rice, reed-grass, two beard-grasses, and several panic grasses. The following, though quickly and thoroughly dissemi- nated, are not native to our State : Barn-yard grass, crab-grass, foxtail or pigeon-grass, sweet vernal-grass, Timothy, meadow foxtail, the larger red- top so popular for lowlands, tall oat-grass, orchard grass, tall fescue, perennial rye-grass, quick-grass. Besides the true grasses, there are about one hundred and eighty species of grass-like plants mostly found on marshes, which are called sedges. They are mostly confounded with the grasses except by the botanist. In addition to these are some twenty-five other narrow-leaved and grass- like plants known as rushes which furnish more or less herbage. Many of the sedges and rushes make hay of fair quality when cut early before they become harsh and woody. On the Jack-pine plains and in many other portions of the sandy stump- lands in the northern counties are two species of sedges found abundantly on dry land. These are Carex Pennsylvania Lam., and C. umbellata mcina Dewey ; they are popularly called grasses by the residents of those counties. Inquiries have frequently been made concerning the name, and statements made to the effect that they were very nutritious and that cattle got fat on them early in the spring. So far as I have observed, cattle prefer something else as it starts in spring, thus leaving the sedges untouched to grow all summer and remain green under the snow till the following spring. In spring the cattle eagerly devour the last year's growth of the sedges and thrive on it. This is but another evidence that the quality of the fodder is not of so great importance, provided animals can get enough of it. and can be induced to eat it. Besides the native grasses, sedges and rushes, there are great numbers of other herbaceous plants, usually one here and there which are eaten by 2± MICHIGAN ACADEMY OF SCIENCE. hungry stock. Leaves and the tender growth of shrubs and young trees are often eaten in great quantities, and in times of scarcity cattle get astride of young trees bending down the tops so as to reach the leaves and twigs. Sheep eat the greatest variety of plants and thus where they feed closely are valuable aids in the clearing of a new country. They eat briars, elders and sprouts of stumps, but will leave some things which they do not like. The weeds that are thus left have an excellent chance to spread and in time occupy much of the ground once covered by the nutritious and edible plants which have been removed. Here we see one of the most ex- cellent reasons for the interference of man in removing the weeds and in encouraging the introduction of the more valuable fodder plants. While these early native pastures and meadows are of incalculable value to the pioneer, without some care they soon deteriorate. In times of great scarcity of feed in a new country, farmers used to fell trees that cattle might eat the twigs, or "browse," which contain much starch and protoplasm stored away by the trees ready to be used in giving the young growth a start on the approach of warm weather. Michigan has no native species of clover. NATIVE BEE PLANTS. In Michigan there is a very large number of plants which furnish a good quality of honey. If the species is abundant in any region, it usually becomes known to the apiarist as a good bee plant ; if not abundant it very likely fails to attract attention. A plant may be rare or important in one region and abundant in another. In autumn, asters and golden rods are known as excellent bee plants, because some few of the many species in the State are plentiful in nearly every neighborhood, but the same sorts of 'asters or golden rods do not everywhere throughout the State furnish a great amount of the honey. As a rule those plants which produce odor- ous or showy flowers afford honey and will be visited by honey bees unless the flower is of a shape which makes it impossible for the bee to reach the food. * Probably in the State there are of native plants, introduced weeds and field crops, a thousand species which furnish excellent food for bees. This is nearly one hundred times as many as the bee keeper has in mind, unless he has given unusual attention to the subject. Our open low lands furnish a large proportion of the bee pasture ; the forest some; the weeds and some of the field, garden and orchard crops a fair amount. Extremely dry or very wet weather are both unfavorable to the yield of honey. Drainage of the swamps and the clearing of waste places are unfavorable to the interests of the bee keeper. As the botanist now looks at the subject, colors and odors are mere advertisements to call the attention of insects to the rich supplies of food in store for them. It may be said that the honey is there for the bees, but primarily it is there for the good of the plant, secondarily for the good of the insect. Had good old Dr. Watts lived in our day, he would have no doubt written his familiar verse in this way : How doth the little busy bee Improve each shining hour! By carrying pollen day by day To fertilize each flower. BEAL ON MICHIGAN FLORA. 25 WEEDS, NATIVE AND INTRODUCED. A new country is comparatively free from weeds, but as the years pass by, one after another, weeds are introduced. Some of them are natives of the neighborhoods in which they are found, but most of them have been introduced from other portions of our own country or from foreign coun- tries. The farmer is not inclined to adopt Emerson's notion of a weed as "a plant whose virtues have not yet been discovered/' at least he doesn't purpose trying to find a use for them. The seeds of most weeds find their way onto a farm nicely mixed with seeds of grasses, grains and clovers, which are drilled in or sowed broadcast on fertile soil, where they are afforded an excellent opportunity to grow and multiply. In some in- stances weeds are introduced as a part of the packing or straw employed to protect castings, marble, crockery or fruit trees. Such foreign packing should always be burned at once. By these processes the older the country the more troublesome weeds it will have, as every new intruder usually conies to stay. In most cases a weed becomes well established before it is discovered and the inquiry comes : "What is it, and how can I get rid of it?" Weeds' are likely to become most troublesome, where farmers are slovenly and where they are not thorough in cultivating throughout the season the so-called "hoed crops." In regions where "hoed crops" are seldom raised or only raised in small quantity, certain weeds are likely to prove very annoying. The majority of our weeds have been introduced from Europe, as will be seen by a comparison of the two lists which follow : LIST OF WEEDS INTRODUCED FROM EUROPE AND ASIA.

Kuntze, there are only two species of native plants which are of any prominence as poisonous to the touch, and often these two are not poisonous to all persons. The latter plants or shrubs, are known as poison sumach or poison dogwood (Rhus Vernicc L.), and poison ivy, or poison oak (Rhus radicans L.). The last named plant is the most troublesome, as it is often common on dry land, while the one previously noticed is confined to swamps which are not so often fre- quented. Poison ivy has three leaflets to each leaf, while the handsome Virginian Creeper, often confounded with it. usually ha.s five leaflets to the leaf, and is harmless. The roots, leaves or flowers of many of the MICHIGAN ACADEMY OP SCIENCE. medicinal plants are more or less poisonous when eaten in sufficient quantity, but fortunately, in nearly all such cases, there is something repulsive to the taste or to the smell. Unless one is a botanist or takes the advice of a good botanist, it is safest to let strange plants alone. NATIVE PLANTS PAST DISAPPEARING. The fathers and grandfathers of many of us spent a considerable por- tion of their energies in clearing away trees, shrubs, and breaking up the land that they might have fertile fields. The newer portions of our State are still rapidly undergoing this same transition. As the country becomes older and more thickly settled almost every- thing seems to conspire against the trees and smaller plants. Proprietors are still making extensions to their clearings. The "tidy" farmer ditches the cat-holes and marshes, clears out the elders and viburnums to make more room for turnips and better grasses. He turns stock into the wood lot and the flowers of spring and summer retreat to the brush-heaps and a few places inaccessible to the cattle. Fire burns out the dried-up swamps. The officers of the railroad see that the strips alongside the track are often mowed. The highways are attacked and the larger vegetation removed. In places, nurserymen or their agents collect large numbers of the choicer wild plants, as prairie roses and lady's slippers. Near high schools and colleges, the student collectors exterminate many choice plants, root and branch. Many wild plants vigorously protest against these attempts to- ward their extermination, and start again and again to recover the lost ground, but with the hand of a thorough farmer against them, sooner or later they succumb, the scattered remnants only surviving in the few re- maining swamps, along railroads, on a few ragged hills and out of the way places. Let me utter a vigorous protest against the practice of collecting great quantities of flowers, just to carry home and throw away. And may I hope that every teacher who chances to read this paragraph will also utter a protest against this practice? LIST OF TREES INDIGENOUS TO MICHIGAN. The distinction between a tree and a shrub is a purely arbitrary one. If the trunk attains a diameter of one foot the species ranks as a tree, if less than a foot it ranks as a shrub. The papaw and the witch-hazel rank as trees in some regions of the country, but in Michigan I have not in- cluded them in the list of trees of the State. I enumerate ninety trees for Michigan.
