Distribution records of Southern Indiana vascular plants II.ABSTRACT. Ongoing collecting and review of existing collections has resulted in additions to the collection in the Indiana University Southeast History The Indiana University Falls City Area Center was established by Floyd McMurray in 1941 as an extension center of Indiana University in New Albany, Indiana and Jeffersonville, Indiana. Herbarium herbarium, collection of dried and mounted plant specimens used in systematic botany. To preserve their form and color, plants collected in the field are spread flat in sheets of newsprint and dried, usually in a plant press, between blotters or absorbent paper. . New and old collections yielded about 160 new vascular plant vascular plant or tracheophyte Any plant that has a specialized conducting system consisting mostly of phloem (food-conducting tissue) and xylem (water-conducting tissue), collectively called vascular tissue. county records for Clark, Crawford, Floyd, Harrison, and Jefferson counties in southern Indiana Southern Indiana, in the United States, is notable because it is culturally distinct from the rest of the state. The area's geography has led to a blend of Northern and Southern culture that is not found in the rest of Indiana. . The Indiana vascular species that are listed as state extirpated, endangered, threatened, or rare are noted. Other species that may become listed, or are otherwise noteworthy, are briefly discussed. Keywords: Vascular plants (Bot.) plants composed in part of vascular tissue, as all flowering plants and the higher cryptogamous plants, or those of the class See also: Vascular , 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 Perry, Scott, and Washington counties. This area of southern Indiana includes the lowermost parts of the following regions: the Mitchell Karst Karst (kärst), Ital. Carso, Slovenian Kras, limestone plateau, W Slovenia, N of Istria and extending c.50 mi (80 km) SE from the lower Isonzo (Soča) valley between the Bay of Trieste and the Julian Alps. Plain and Knobstone Escarpment The Knobstone Escarpment is a rugged geologic region in Southern Indiana. Physically, the Knobstone Escarpment is the most rugged terrain in Indiana. The highest hill in the area is Weed Patch Hill, with an elevation of 1,056 feet above sea level. sections of the Highland Rim The Highland Rim is a geographic term for the area in Tennessee surrounding the Central Basin. Nashville is largely surrounded by higher terrain in all directions. Geologicially, the Central Basin is actually opposite, being a dome. Natural Region and the Shawnee Hills The Shawnee Hills is a region of Western Kentucky and Southern Illinois. The Kentucky part consists of many low, rolling hills, primarily underlain by rocks of Pennsylvanian age, including coal. Natural Region (Homoya et al. 1985). Ongoing collecting and review of existing collections in the herbarium have yielded about 160 new vascular plant county records since the publication of our last distribution list (Maxwell & Thomas 2003). Possible state records and noteworthy collections are listed alphabetically by their scientific names and briefly discussed, followed by state extirpated, endangered, threatened, rare, and watch list species. Table 1 includes distribution records, with their collection vouchers, mainly for Clark, Crawford, Floyd, Harrison, and Jefferson counties. Nomenclature conforms primarily to the Field Guide to Indiana Wildflowers (Yatskievych 2000), with authors of plant names, following Brummitt & Powell (1992). Some nomenclature, primarily for ferns, grasses, and common names, is from Mohlenbrock (1986), Gleason & Cronquist (1991), or Yatskievych (2000). Determination of species status follows the Indiana Natural Heritage Data Center's Endangered, Threatened, and Rare Vascular Plants list, from the Indiana Department of Natural Resources The Indiana Department of Natural Resources is the agency of the U.S. state of Indiana charged with maintaining natural areas such as state parks, state forests, recreation areas, etc. (DNR See dynamic noise reduction and domain name resolver. ), Nature Preserves (10 April 1996). Former and present collectors include Indiana University Southeast students, the authors, and several volunteers. METHODS Sites of listed species are reported to the Indiana Department of Natural Resources, Division of Nature Preserves. Vouchers are currently held at the Indiana University Southeast Herbarium. Some collections are sent to Michael A. Homoya, a botanist with the Indiana Department of Natural Resources. Specimens are sent to Dr. George and Kay Yatskievych at the Missouri Botanical Garden The Missouri Botanical Garden is a botanical garden located in St. Louis, Missouri, and is also known informally as "Shaw's Garden" (named for founder Henry Shaw, a botanist and philanthropist). as well. Methods and criteria for listing Indiana's extirpated, endangered, threatened, and rare vascular plant species have been discussed by Aldrich et al. (1986).
