Distribution records of Southern Indiana vascular plants.

ABSTRACT. Collections in the Indiana University Southeast Herbarium were reexamined and entered into a database. New and old collections yielded over 100 new vascular plant county records for Clark, Crawford, Floyd, and Harrison Counties in southern Indiana. Indiana vascular species listed as extirpated (SX), endangered (SE), threatened (ST), or rare (SR) are noted. Others species which may become listed, or are otherwise noteworthy, are briefly discussed.

Keywords: Vascular plants, Indiana, distribution records

The Indiana University Southeast Herbarium serves as an educational and community resource as well as a research exchange facility. The herbarium contains vascular plant collections primarily from Clark, Crawford, Floyd, Harrison, and Jefferson Counties, with occasional collections from Washington, Scott, and Perry Counties. This area of southern Indiana includes the lowermost parts of the following regions: the Mitchell Karst Plain and Knobstone Escarpment Sections of the Highland Rim Natural Region, the Scottsburg Lowland and Muscatatuck Flats and Canyon Sections of the Bluegrass Natural Region, and the Shawnee Hills Natural Region (Homoya et al. 1985). The Indiana University Southeast Herbarium is in the process of creating an online database of its vascular plant collection at www.ius.edu/ biology/herbarium/homepage.stm.

Ongoing collecting and review of existing collections in the herbarium have yielded over 100 new vascular plant county records since the publication of the last distribution list from the Indiana University Southeast Herbarium (Maxwell & Emmert 1995). Possible state records and noteworthy collections are listed alphabetically by their scientific names and briefly discussed, followed by a listing of state endangered, threatened, and rare species. Table 1 includes distribution records for Clark, Crawford, Floyd, and Harrison Counties with their collection vouchers. Nomenclature conforms primarily to the Field Guide to Indiana Wildflowers (Yatskievych 2000), with authors of plant names, following Brummitt & Powell (1992). Some nomenclature, primarily ferns, grasses, and common names cited, is from Mohlenbrock (1986), Gleason & Cronquist (1991), Homoya (1993) and Yatskievych (2000).

Determination of species status follows the Indiana Natural Heritage Data Center Endangered, Threatened and Rare Vascular Plants list, Indiana, from the Department of Natural Resources (DNR), Nature Preserves (27 January 1998). County status was also determined from the DNR, Nature Preserves web site, www.in.gov/dnr/naturepr (16 November 1999).

Former and present collectors include Indiana University Southeast students, the authors, several volunteers, Ray Weatherholt and several of his biology students from Floyd Central High School.

METHODS

Sites of listed species are reported to Indiana DNR, Nature Preserves. Vouchers are currently held at the Indiana University Southeast Herbarium. Some collections are sent to the DNR, Nature Preserves for confirmation by Michael A. Homoya, DNR Botanist, as well as by George and Kay Yatskievych at the Missouri Botanical Garden. Methods and criteria for listing Indiana's extirpated, endangered, threatened, and rare vascular plant species have been discussed by Aldrich et al. (1986).

POSSIBLE STATE RECORDS AND NOTEWORTHY COLLECTIONS

Achyranthes japonica (Miq.) Nakai (Amaranthaceae). Japanese Chaff Flower. A native of Asia which was introduced into Kentucky (Gleason & Cronquist 1991). Small, shrubby plants, common along the upper floodplain slopes and banks of the Ohio River in the Indiana counties across from Louisville, Kentucky. Colonies extend back from the river and down river to the west. We consider "W.E. Thomas 470" from Crawford County the state record voucher.

Egeria densa Planch. (Hydrocharitaceae). Brazilian Water-weed. The state record, "W.E. Thomas 294," was collected in shallow water from Wyandotte Lake in the Harrison-Crawford State forest. An aquarium plant "that has become naturalized in various localities in the United States, primarily in the southeast" (Beal & Thieret 1986).

Clematis terniflora DC. (= C. dioscoreifolia Levi. & Vaniot) (Ranunculaceae). A native of Japan which appears occasionally with other vines along the Ohio River.

Fatoua villosa (Thunb.) Nakai (Moraceae). Hairy Crabweed, Mulberry Weed. Reported in Flora of North America (3):390.1997, but neither the voucher nor the author of the Indiana report was identified (K. Yatskievych pers. commun.). The Floyd County record, "Maxwell s.n., 9/20/1995" validates the FNA report and can be listed as the state record voucher. A native of tropical Asia, two plants were collected in a New Albany yard in 1995. We know of no other reports in Indiana.

Humulus japonicus Siebold & Zucc. (Moraceae). Japanese Hops. An introduced native of East Asia. The vine is fairly common along roadsides next to the Ohio River.

Lespedeza bicolor Turcz. (Fabaceae). Bicolor Lezpedeza. Two small shrubs were found in the open field northeast of the old black powder plant at Charlestown State Park. Reported for Indiana in the Proceedings of the Indiana Academy of Science, 1953. The state record voucher collected by "Buser & Ahles s.n." in Fountain County is probably in the University of Illinois Herbarium at UrbanaChampaign.

Liparis loeselii (L.) Rich. (Orchidaceae). Loesel's Twayblade. Found by Homoya in Jackson County on the Muscatatuck National Wildlife Refuge (1990). Thomas discovered a population of about 14 plants distributed in the lower end of a seep in Charlestown State Park off Trail 1. This Clark County population represents a further southern extension as suggested by Homoya (1993).

Melothria pendula L. (Cucurbitaceae). Creeping Cucumber. This vine was considered state extirpated (SX) until three sites were discovered by Thomas in Charlestown State Park in 2000. The vines seemed to be thriving in spite of being in competitive habitats: a roadside ditch, an open disturbed area, and the edge of the escarpment over Fourteen Mile Creek. Since 2000 the Creeping Cucumber has been found in numerous sites throughout Charlestown State Park. It has also been found in roadside ditches in Floyd County along the lower edges of the knobs beside the Ohio River floodplain.

Mentha x rotundifolia (L.) Huds. (Lamiaceae). Apple Mint. A possible hybrid for southern Indiana. Several other collections have been made of this mint (Yatskievych 2000). Its occurrence in the state may be more common than the current reports indicate.

Orthodon dianthera (Buch.-Ham.) Hand. Mazz. (= Mosla dianthera (Buch.-Ham. ex Roxb.) Maxim) (Lamiaceae). A native of East Asia, established in moist places in the southeast (Gleason & Cronquist 1991). Recorded for Indiana in Kartesz & Meachan's 1999 Synthesis without a reference (K. Yatskievych pers. commun.). Homoya was aware of a site in the Harrison-Crawford State Forest and made a collection 26 September 1997 in Harrison County. The Homoya collection is the state record and "W.E. Thomas 36," a second collection. Thomas reports the population expanding in open areas left by logging at two different sites in Harrison-Crawford State Forest. This may be another species moving up from Kentucky and becoming common in southern Indiana.

Packera anonyma (A.W. Wood) W.A. Weber & A. Love (= Senecio anonymous A. Wood, S. smallii Britt.) (Asteraceae). Occasional on thin soil over a limestone ledge in Charlestown State Park. Perhaps a recent range expansion phenomenon (Homoya & Hedge 1990). Indiana Watch List (Yatskievych 2000).

Papaver dubium L. (Papaveraceae). Garden Poppy. The collection "Maxwell 3166," is the second report of the Garden Poppy along a different railroad track in Clark County. About 15 plants were noted along the tracks about 2 1/2 km. north of highway I-265 along State Road 62 in 1998, but this second colony did not persist probably because of herbicide spraying along the right-of-way. The collection "W.E. Thomas 271," along State Road 31 north of Speed, indicates the initial Clark County colony is persisting and perhaps expanding in the much wider strip between State Road 31 and the railroad track. Its occurrence in the state may be more common than reports indicate.

Platanthera lacera (Michx.) G. Don. (Orchidaceae). Green Fringed Orchid. This orchid is the most common Platanthera in Indiana (Homoya 1993), but is primarily found in the northern part of the state. A single plant was discovered by Thomas in the edge of a wet depression off Jersey Avenue east of the current Charlestown State Park boundary in an area expected to become annexed to the park. A photo voucher was taken 6 July 2002. This report indicates a range extension to the south as predicted by Homoya (1993). Indiana Watch List (Yatskievych 2000).

Pycnanthemum muticum (Michx.) Pers. (Lamiaceae). Mountain Mint. The state record collector, K.F. Duffy, reports colonies in full sun, in poor clay soil next to a pond in a Harrison County hardwood forest. Deam (1940) excludes the species, citing reports, but no specimens. Schneck's report (Deam 1940) for the Lower Wabash Valley is probably correct. Mohlenbrock & Ladd (1978) show distribution in Wabash County, Illinois, next to the Wabash River.

Duffy sent a collection, "K.F. Duffy s.n., 21 September 2002," to Kay Yatskievych at the Missouri Botanical Garden for verification; and this becomes the Indiana voucher specimen for the species and the county record. Our specimen, "K.F. Duffy 1," is a later collection from the same population.

Selaginella eclipes Buck (Sellaginellaceae). Small Spikemoss. First thought to be S. apoda (L.) Fern.(SE), later determined by Homoya as S. eclipes, and also confirmed by G. Yatskievych. Occasional to locally common in Charlestown State Park.

Solanum sarachoides Sendter (Solanaceae). Hairy Nightshade. A Gastony collection, "Gastony s.n., 17 July 1985, Fee Lane and Highway 46 Bypass, Monroe County, Bloomington, was discovered in the Indiana University Herbarium. This may be the state record. The Gastony collection ... "was apparently an escape to a roadside that was some distance from the experimental field" (K. Yatskievych pers. commun.). The experimental field refers to where Dr. Charles B. Heiser, Jr., of Indiana University carried out some of his well-known hybridization work with sunflowers, nightshades and domestic plants. Heiser (1969) refers to using Solanum sarachoides in his crosses to rediscover the "wonderberry."

The "Maxwell 3367, 25 August 2000," collection from Charlestown State Park would be a second report. This introduced weed was found in a disturbed area of the park and is persisting. However, it does not show the invasive capacity of other introduced species in the park.

INDIANA STATE ENDANGERED (SE)

Asplenium bradleyi D.C. Eaton (Aspleniaceae). Bradley's Spleenwort. Noted in Dubois County, 23 October 1984, by Homoya & Abrell (1986). "W.E. Thomas 159" was collected from a population of 13-15 plants scattered on several sandstone boulders in an open area near Wyandotte Cave in the Harrison-Crawford State Forest.

Gentiana villosa L. (Gentianaceae). Striped Gentian. Deam (1940) reports two collections from southeast Harrison County in black and white oak woods. A Harrison County site was located during a DNR conducted survey for the Indiana Natural Heritage Program. A fragment, "W.E. Thomas 37," was collected in the Harrison County part of the Harrison-Crawford State Forest in a cedar woods along Cold Friday Road. Thomas reports a scattered population of about 30 40 plants in the woods. These sites are in Harrison County, but we cannot be sure they are the same.

INDIANA STATE THREATENED (ST)

Acalypha deamii (Weath.) Ahles. (= A. virginica L. var. deamii Weath.) (Euphorbiaceae). Mercury. Michael Homoya identified this species in October 1994, in the Jenny Lind Run area of the Indiana Army Ammunition Plant. A few plants were also found on the south bank of Fourteen Mile Creek near the Ohio River. Over the last few years sizable populations were found by Thomas in Floyd County, along the Ohio River in New Albany, and Harrison and Crawford Counties. Maxwell ("Maxwell 3409, 10/19/2000") found a population of about 100 plants on a Fourteen Mile Creek sand bank near the north bridge in what is now Charlestown State Park. Additional plants have turned up in the park along Trails 1, 2 and 3. It now appears so common in our area new sites are not reported to DNR, Nature Preserves.

Diodia virginiana L. (Rubiaceae). Buttonweed. Collected from large colonies along the Ohio River in Floyd and Crawford Counties, and also found along the wet perimeter of Deam Lake in Clark County. See Homoya et al. (1995) for additional locations. Now believed common along the Ohio River.

INDIANA STATE RARE (SR)

Gentiana flavida A. Gray (G. alba Muhl.) (Gentianaceae). Yellowish Gentian, Pale Gentian. An Indiana University Southeast Herbarium collection, "C.W. Henson 43, 19 Sept. 1975," from the Harrison-Crawford State Forest in a dry, oak woods clearing, was determined Gentiana villosa. Reexamination, as suggested by Homoya, showed it to be Gentiana flavida. The exact county distribution is unknown.

Northoscordum bivalve (L.) Britton (Liliaceae). Crow Poison. A colony of perhaps 60 plants was found on a low rock bluff along State Road 62 within Harrison-Crawford State Forest, west of Wyandotte Lake.

Oxalis illinoensis Schwegman (Oxalidaceae). Illinois Woodsorrel. Two large Clark County populations were pointed out by Homoya about 1994 on the wooded floor of Lick Creek Ravine, in what is now Charlestown State Park. At that time, one population contained about 100 individuals and the other 500-1000. Since then several additional clusters have been found in the park along with a population of about 2000 individuals spreading down from the upper bluff on the east side of Lick Creek towards Fourteen Mile Creek. Two colonies, one with perhaps 100 plants, the other smaller with perhaps 20 plants, were found by Thomas in Crawford County. Both these sites were within the Harrison-Crawford State Forest along the upper tributaries of Dry Run Creek.

The Illinois Woodsorrel has leaflets shallowly lobed with green margins; the Big Yellow Woodsorrel (Oxalis grandis Small) has leaflets deeply lobed with purplish-brown margins (Yatskievych 2000). Other characteristics are similar except the Illinois Woodsorrel has a small tuberous root (Homoya pers. commun.). We believe the Illinois Woodsorrel is more common than the Big Yellow Woodsorrel in our south central Indiana area.

Spiranthes vernalis Engelm. & A. Gray (Orchidaceae). Spring Ladies' Tresses, Grassleaved Ladies' tresses. Observed by Thomas & Howell Curtis, Charlestown State Park in a disturbed area north of Trail 1 parking. "W.E. Thomas 332" serves as a Clark County voucher.

Tragia cordata Michx. (Euphorbiaceae). Heart-leaved Noseburn. Homoya identified this vine in the rocky woods, north of the west little bluestem glade in Charlestown State Park.
