INTRODUCTION.

The first Michigan Flora entitled a “Catalogue of the Phenogamous 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 Golleges, 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 as 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 soi]. 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 pr are themselves.

The following is a list of the chapters found in the last edition of fhe Flora that are omitted in this edition:

. Planting the Roadside and about the Home. Planting a Grove.

-- Planting a Wild Garden.

Native Trees and Shrubs selected for the Color of their Leaves in Autumn. Native small Trees and Shrubs distinguished for their Fiowers.

Native Shrubs or Trees distinguished for their beautiful Fruit.

A list of native Trees and Shrubs distinguished for their showy or brilliant

colored Bark.

HERBARIA CONSULTED.

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. ue

- TOPOGRAPHY.

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 with 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. Rominger, 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 an 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, Roscommon 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 chafacter 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 bas 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, we 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, Cercis Canaden- sis, Gleditsia triacanthos, Cornus florida, Nyssa multiflora, and Morus rubra, which belong to Ohio and Central Illinois, have crept northward, favored by the mild influence of the lake winds, through the central aud 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 penin-

/

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 soft 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, Ribes rubrum, Chio- genes hispidula, Salia candida, Smilacina trifolia, Pogonia ophiogbos- soides and Calopogon pulchellus. Arbor-vitee, 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. lutea) mixed with a fine, tall growth of striped maple (A. Pennsylvanicum) 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 Vacciniwms, 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. lutea) also begins to be a common forest tree, and attains a large size. The usual timber of the barrens is Jack

-

Pine (P. Banksiana). Climatic and other influences have combined to _

produce groves composed entirely of this species of large size and of great

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 spar- 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 43°. 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 oy quite to the Indiana line, and the same is true of

white pine. ot “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 Mitchella repens, Maianthemum Canadense, Trillium grandiflorwm, perhaps, and a few ferns, particularly Asplenium Filix-femina and Phegopteris Dryop- teris. Other species occur, of course, but not so abundantly. In iore open places, and on ridges, we meet Rhus aromatica and Comptonia along with wintergreen (Gaultheria) and trailing arbutus (Hpigwa), and are often fortunate enough to find the wax-white, fragrant flower of Moneses 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 Linnea 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 Poli- folia, Kalmia glauca, Lonicera oblongifolia, Cardamine pratensis, Ger- ardia aspera, Mitella nuda, Eriophorum .vaginatum, etc. On lake mar- gins we shall find Lysimachia and the blue Pontederia and more rarely, Nesea and Eleocharis quadrangulata. The lake itself, most likely, will be full of Nymphaea, Nuphar, Utricularias, and a world of Potamoge- tons and similar water weeds. Shrubby Vacciniwms line the bluffs, and here and there gleam the white trunks of paper birches against the dark background of pines. a

“In the thick-pine country, where the lumberman’s ax has let in the sunlight, new plants spring up freely. Here, Prunus Pennsylwanica 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

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.

“Tn 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:

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 Rasacew by six species, Composite by thirteen species, Graminee by nine species, Vacciniacee by four.

The following large and prominent families of the State are not repre-

sented in the list given above: Ranunculacee, Crucifere, Caryophyllacee,

Saxifragacee, Umbellifere, Orchidacee.

\ 18 MICHIGAN ACADEMY OF SCIENCE.

Most remarkable of all is the absence of any Papilionticee though the family is second in size only to the Composite. - The Papilionacee 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 Be has burned over the ground and killed the tops of the plants.

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. NorTHERN PLANTS FOUND ON THE EAST SIDE OF THE STATE AND NOT ON THE WEST.

Botrychium Lunaria (L.) Swartz. Moonwort.

* Botrychium simplex Hitchcock. Moonwort. Carex capillaris L. Sedge. . Carex durifolia Bailey. Back’s Sedge. (Carex Backii Boott.) Carex Houghtonii Torr. Sedge. Dracocephalum parviflorum Nutt. Dragon-head. Kalmia angustifolia L. Sheep Laurel. Lambkill. Kalmia glauca Ait. Swamp Laurel. Pale Laurel. Picea Canadensis (Mill) B. S. P. White Spruce. (Picea alba Link.) Ribes lacustre (Pers.) Poir. Swamp Gooseberry. Sparganium simplex Huds. 3

B. SoutHERN PLANTS FOUND ON THE WEST SIDE OF THE STATE AND NOT ON THE EAST.

Adiantum pedatum L. Maiden Hair Fern. Acer saccharinum L. Silver Maple. (Acer dasycarpum Ebrh.)

Rubus occidentalis L. Black Raspberry. Sambucus Canadensis L. Common Elder. Sassafras Sassafras (L.). Karst.

(Sassafras officinale Nees.)

Ulmus fulva Michx. Red Elm.

Ulmus racemosa Thomas. Rock Elm.

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.
