Ray C. Friesner

The Butler University Botanical Studies journal was published by the Botany Department of Butler University, Indianapolis, Indiana, from 1929 to 1964. The scientific journal featured original papers primarily on plant ecology, taxonomy, and microbiology. The papers contain valuable historical studies, especially floristic surveys that document Indiana’s vegetation in past decades. Authors were Butler faculty, current and former master’s degree students and undergraduates, and other Indiana botanists. The journal was started by Stanley Cain, noted conservation biologist, and edited through most of its years of production by Ray C. Friesner, Butler’s first botanist and founder of the department in 1919. The journal was distributed to learned societies and libraries through exchange. During the years of the journal’s publication, the Butler University Botany Department had an active program of research and student training. 201 bachelor’s degrees and 75 master’s degrees in Botany were conferred during this period. Thirty-five of these graduates went on to earn doctorates at other institutions. The Botany Department attracted many notable faculty members and students. Distinguished faculty, in addition to Cain and Friesner , included John E. Potzger, a forest ecologist and palynologist, Willard Nelson Clute, co-founder of the American Fern Society, Marion T. Hall, former director of the Morton Arboretum, C. Mervin Palmer, Rex Webster, and John Pelton. Some of the former undergraduate and master’s students who made active contributions to the fields of botany and ecology include Dwight. W. Billings, Fay Kenoyer Daily, William A. Daily, Rexford Daudenmire, Francis Hueber, Frank McCormick, Scott McCoy, Robert Petty, Potzger, Helene Starcs, and Theodore Sperry. Cain, Daubenmire, Potzger, and Billings served as Presidents of the Ecological Society of America. Requests for use of materials, especially figures and tables for use in ecology text books, from the Butler University Botanical Studies continue to be granted.

THE FLORA OF THE SHADES STATE PARK, IN­DIANA, AND THE GEOGRAPHICAL DISTRI­BUTION OF THE SPECIES

By ]:\CK Iv1cCoRMTCK

The great number of deeds issued in west-central Indi<lI1a within a few years 01 the completion of the original land sun'ey of 1820 justifies the supposition that the fertile till-soils of the region were an alluring inclemni fication for the hardships necessarily borne by the first colonists. The fertility of the land, however, was concomitantly to result in the decimation of the forest-covered acres of that portion of the State within half a century. Record (40) in a resume of forest conditions in 1'l'Iontgomery County, Indiana, related that. "Trees and saplings were cut and their trunks were made into corduroy roads. Regular logging bees were held and tree after tree was cut, rolled together, and burned. The best (trees) were cut into rails or hewn into sills, or used for firewood."

The dissected land bordering Sugar Creek and its tributaries, how­ever, provided little enticement to the farmer; and thus tbeir forests escaped the ruthless destruction that befell those of the sl1rrounding uplands. One such area, which was spared denudation, became known as the" Shades of Death." Its name was an illusion, not only to the deep shadows beneath the nearly unbroken canopy of the forest, but also to the crude murders which occurred in the area within a few decades of its settlement. Wbile the land was purchased with the more suitable uplands, ml1ch of it was leit idle and \'irtually untouched. The title to the land passed from family to family until several hold­ings were consolidated and a corporation, known as the Garland Dells lVI ineral Springs Association, was formed to exploit the natural mineral waters (Blatchley, 2). \\lithin a decade of the turn of the century, the resort became the property of Joseph \V. Frisz. A love of the land caused Frisz, the "pioneer conservatIonist," to reinvest much of his profit in the laIJd, until by 1942 "The Shades Scenic Park" comprised more than 2,100 acres (Roll, 41).

\Vhen Joseph Frisz died in 1939, his corporation stock was divided among his children. \Vith several stockholders, each possessing a

171

different opinion of operational procedure, the park became a liability. \Nhen the Shades was offered for sale .. "Timber companies im­mediately evinced great interest in the magnificent trees, especially the top-grade white oak. . . . Thus, the Shades seemed doomed for destruction," (Indiana Department of Conservation, 31). A campaign to "Save the Shades" was initiated immediately and found the sym­pathetic support of the school children, fraternal organizations, and other citizens of Indiana and her neighboring states. The park was thus dedicated on July 18, 1948, as the "Shades State Park;' the fifteenth such area set aside in Indiana.

Various widely known botanists have visited the Shades since the late 1800·s. The only known data published regarding its plant life, howe\'er, are brief notes by Deam (12) and Friesner (27). Soon after its acquisition by the Indiana Department of Conservation. it was apparent that a botanical survey was necessary to determine the types of plants present in the park, and to determine what measures might be necessary for the preservation of the less common species. This survey was initiated under the auspices of the DiYision of Lands, "Vaters and State Parks, Indiana Department of Conservation, and the Botany Department of Butler University while the author served as resident naturalist.

SIZE AND LOCATION OF THE AREA

The Shades State Park occupies an area of 1,952 acres situated in Brown Township, Montgomery County; Howard Township, Parke County; and Jackson Township, Fountain County, Indiana. (T. 17 N .. R. 6 W., Sections 2. 3, 4,5,9, 10,11 ; T. 18 N" R. 6 W" Sections 33, 34), It is approximately 5 miles north of Waveland', 50 miles west-northwest of Indianapolis, and 125 miles south-southeast of Chicago.

GEOLOGY, PHYSIOGRAPHY AND SOIL FEATl:RES

The Shades State Park lies within the Tipton Till Plain described by Malott (37), an area which was subjected to glaciation by both the Illinoian and Wisconsin (Tazewell substage) glacial stages. The soil of the uplands, primarily Miami silt loam, is derived from glacial and loessial materials. Tt is known locally as "sugar-tree land" on account of the predominance of Acer saccharum (Jones and

Orahood, 33), The soil of the ridges and ravines has been variously derived from the bedrock, glacial debris, and organic remains.

Bedrock consists of intermixed strata of shales, limestones, and sandstones of the Mississippian and Pennsylvanian eras. "The Mans­field sandstone (Pennsylvanian), being more resistant than the

strata above and below it, has weathered into . . . bold eli f fs . . ." reaching an extreme exposure of two hundred feet above deeply entrenched Sugar Creek (Jones and Orahood, 32). The tributaries of the main stream have their origin in, or are fed by, springs flowing from points where an impervious shale layer is e"-'"Posed. These streams, in their adjustment to the level of Sugar Creek, have cut ravines of various width and depth. Where the springs must flow O\'er a broad surface for any distance. beds 0 f travertine, or tufa rock, often are formed. The extreme elevation on the park property is 771 feet above mean sea level, while the minimum elevation is slig-htly less than 550 feet.

FLORA OF THE PARK

During the snmmers of 1950 and 1951, frequent excursions were made into all sections of the Park. Prudent collections were made of each species foulld in order. not to ·disturb the natural conditions. I n the course of the field work, 329 new county records, including 2 species. 6 varieties, and 10 forms new to the State, were discovered. ?vfany of these have been published, and the remainder will be pub­lished, in the Proceedings of the Indiana Academy of Science as a part of the Indiana Plant Distribution Records (23, 24).

Specimens of plants reported as State or county records werer deposited in the herbarium of Butler l!niversity. while many of the other specimens are now in the herbarium of Rutgers LT niversity, the State LT niversity of New Jersey, and the private herbarium of ·Mr. Julius Cohen, Newark, N. J.

The nomenclature followed is that employed by Fernald in Gray's 1\1anual of Botany, Eighth Edition (25). the most recent manual treating' this region. The present study of the vascular flora of the Park comprises 627 taxonomic entities (531 species, 56 varieties, 39 forms. and ·1 hybrid) including representatives of 326 genera and

173

98 fal11ilies (table JL). In addition, 23 species are known to be per­

sisting after cultivation but are not reproducing.

The major divisions of vascular plants, Pteridophyta and Sper­

matophyta. are represented by 30 and 597 entities, respectively. The

subdivision Gymnospennae has 4 representatives, while the class

]\fonocotyJedoneae has 141, and the class Dicotyledoneae has 452 representatives. In the latter class, S4 entities are of arborescent habit

and 39 are shrubs or woody climbers.

The famil~1 Compositae has the greatest number of local repre­sentatives, 86 entities. Gramineae, with 71 representatives, ranks second. Other families, in the order of the abundance of their repre­sentatives, are: Leguminosae, 33: Cyperaceae, 29: Polypocliaceae, 27 : Labiatae, 17; and Scrophulariaceae, 17.

DISTRIBl.:TION A~D STATUS IN INDIANA

The range of 613 species known to occur in the Shades was deter­mined from the maps presented by Deam (12) and from the sub­sequently published records of the State Flora Committee of the Indiana Academy of Science (13-24). Forty-five per cent (276) of the species of known distribution are found to be common to all six Indiana floral areas. As a rest)lt of the location of the Park, all the species which appear in its flora are recorded as occurring in the Tip­ton Till Plain; 93% occur in the Illinois Drift plain, 92% in the Unglaciated area, 88% in the Lakes area, 64% in the Lower Wabash Valley, and 61 % in the Prairie area.

The status of plants, whether native or introduced, was determined by reference to Deam (12) and Fernald (IS). Five hundred and twenty species (83 %) are considered native to Indiana; the remaining 107 species have been variously introduced.

DISTRIBCTIO)J IN THE UNITED STATES

The national distribution of 604 species was ascertained fr0111 the accounts gi\'en in Gray's tllanual of Botany, Eighth Edition (Fernald,

(Cowles, 10). One hundred and ninety-one species are extraneous,

i.e .. not recorded from one or more of the eight directions. \Vell over half of the extraneous species (118) are recorded as occurring in all hnt one of the eight directions.

Forty species reach their northern limit, 24 reach the southern limit, 7 reach the eastern limit, and 3 reach the western limit of theit­

range in Indiana. Limits of distribution in the intermediate directions can be ascertained with less certainty because of the limited detail

of the data available. It may be concluded, however, that the affinity of the flora of the Shades is least with the southwestern and north­western regions.

DISCUSSIONS

The vascular flora of the Shades State Park includes a larger number and variety of species than had been anticipated at the inaugu­

ration of the study. \\lhile the survey was as intensive and extensive as the prevailing circl1mstances permitted, several portions of the Park remain to be investigated. There is little doubt that other species, especially members of the Cyperaceae. do occur within the bOlll1daries of the Shades.

Extraneous species have been estimated to comprise from 40 to 45% of the total flora of Indiana (Deam, 11 ; Friesner. 27). 40% of the ferns and fern allies (Clevenger, 6), 62% of the grasses (Cook, 7), 56% of the shrubs (Trefz, 47), anc141% of the trees (Lindsey, 36). The extraneous element in the flora of the Shades is a consistently smaller portion of each gral1p. The difference between the figures presented for the Park and those cited for the State ranges from 8 to 40%. Extraneous species comprise 32% of the total number of species, 237'0 of the ferns and fern allies, 22% of the grasses, 44% of the shrubs, and 33% of the trees found in the Shades.

175

These variations may be attributed to several factors: I) Over 60% of the extraneous species in the flora of the State fail to reach the Tipton Till Plain. the region in which the Shades State Park is situated (Friesner, 27). 2) The majority of the previous estimates was made from 15 to 30 years ago. Range extensions of a number of species have been published since that time. The two most com­prehensive compilations of specific ranges to appear for some time have been published within the past two years: Gray's Manual of Botany, Eighth Edition (25), and the Manual of Grasses of the l.'nited States, Second Edition (Hitchcock, 29). 3) The Shades has no natural pond or lake in which hydrophytic species, several of which are extraneous, could establish. The Park's two artificial lakes, created by raising small dams, apparently are either un fa vorable habitats for those species, due, perhaps. to signi ficant fluctuations in their water Inels which may occur several times a year, or ha\'e not been in existence long enough to allow for the migration and ecesis of a sufficient number of hydrophytes to initiate hydrach succession. (4) The known flora of the Shades is composed of only about one­fourth of the total number of entities known to occur in the State (Deam, 12). As other species are discovered, the percentage of extraneotls species in some groups may be altered significantly.

I\'early one-half of the species found in the Shades are present in every botanical area in Indiana. This number will no doubt be in­creased as our knowledge of the flora of the State becomes more complete. It is notable that the flora of the Shades has more species in common with the Illinoian Drift Area an~ the Unglaciated Area than the other floral regions (excepting the Tipton Till Plain). This situation might be expected, since the topography and geology of those areas resembles that of the Park to a degree. Outcrops of Mans field sandstone occur in both the Areas. Roll (41) observed that the "deep ravines and picturesque Sugar Creek, ,(are) reminiscent of , , , the cliffs of the Muscatatuck River ... " in the "l' nglaciated Area.

The fact that one-sixth of the flora of a tract set aside as "a part of original Indiana" (Cougill, 8) is made up of species which are not native to the State, and in a majority of the cases are not native to North :\merica, bears striking evidence to the rapidity and thorough­ness with which such plants are invading our land.

duced plant probably entered the area occupied by the Park less than 120 years ago. The proportion of non-native species in the flora of the Shades is slightly greater than the 14% cited by Deam (12) for the State. The rapidity of introduction may be somewhat excelled in an area visited by thousands of persons from all parts of the T.)nited States each year. -'"'.ny peculiarity due to such a condition is compen­sated by the distance of the Park from heavily traveled highways. The major portion of the introduced species is found in disturbed areas which have been created either by agricultural activities or by the construction of roads, clearings, or other facilities.

Tbe new county records discovered during the course of this investi­gation may be grouped into three categories: those which merely

.0 fill in" the previously known distribution of a species in the State; those which represent a minor western, southern, or northern exten­sion of the known range of a species in central Indiana: and those which represent significant extension of the range of a species within the State. The first of these groups is by far the largest and requiries little discussion. It is exemplified by such species as Daucus carota, PlIr)'ma leptostachya, Plalltago rugeJi.i, and Aster piloslts. The second category is nearly as large as the first. The records of Dennsta.edtia punctilobula, Tsuga eanadensl:s, and Bidens comosa from Fountain County: Pi111.(S strobus, Atriple.r patula, and Rammculus see/emt·us from Park County: and Botr}'ehiU'lu disseetum, Oxalis curopaea var. bushii f. sub-glabrata. and []upatori!o1t eoelest·inu1·J1, from ::\lontgomery

.. County are to he considered here. The third section is the smallest and perhaps the most interesting. In it may be classed the report of Crota./lar·ia sagitallis, formerly recorded only from the extreme sonth­ern portion of Indiana. Here, too, may be classified the records of Linden/ia allagall-idea and Gratiola virginira. These species had not been reported previously from the Tipton Till Plain.

The apple of Pem, Xica1'ldra ph)'salodrs. previously reported from only 10 connties, is apparently becoming a frequent weed ill cornfields in and about the Park. Its close resemblance to Datura stra11'laniwm has caused it to be overlooked by the landowners and possibly by other botanists.

The entities added to the state floral catalog are primarily varieties and forms which have only recently come to the attention of taxo­

177

nomists in the State. Two species added, howeYer, desen'e particldar

mention:

Lcspcdesa CU1'lcata (Dumont) G. Don, a native of eastern Asia,

was disco\'ered almost simnltaneonsly in ~Vrontgomery and Parke

Counties as a part of this study, and in Crawford County. It has

apparently been introduced as a soil improving legume: but in neither instance had the site been seeded to the species. I ts source is not

known to the local residents.

H oUslo-nia ·m.£l1ima Beck, a species native from western Illinois to

Iowa and Kansas and southward to A rkansas and Texas, grows in an unde\-eloped section of the Park in an intensively pastured field

now dominated by poverty-grass. Dan/honi.a spica/a. This new eastern station may possibly herald a natural migration of the species. [f this

species is migTating eastward, it should have been intercepted pre­

viously in sites much nearer its native range. Apparently, no obsen'a­tion of this occurrence has been made. It may be more plausible to

suppose. therefore, that the species has been introduced by humans or other animals. The inconspicuous habit of the plant and the situation

in which it occurs, well removed from the recreational areas and dwellings, eliminates the possibility that it was formerly cultivated. The chance that it has been introduced in stock rations is very sl ight, since the feed has been produced on the farm for a number of years. The size 0 f the plant is also a factor weighing against the latter possibility since most harvesting machinery would not intercept a plant 50 low In addition, its fruiting period is early, not occurring at the time of harvest. 1t is highly improbahle that wild or domesti­cated animals could retain the seeds in thei r digestive s)'stems long enough to a1Jow them to be transported to the farm f rom the area in which the species is native. Seeds may have been introduced in dung-glO\'es on the hoofs of newly acquired fann animals purchased in Illinois.

The compilation of a catalog of the higher plants of the Shades State Park and the attempt to relate the flora to that of the State LInd the \:ation is not intended as an end in itself. This work. it is hoped, will sen'e as the foundation for a thorough study of the vegetation of the Parle As Tansley and Chipp (46) have postulated, 'Tloristic study nll\~t necessarily precede and condition vegetational study.
