The University of Southern Mississippi Checklist of the vascular flora, restoration plans, and educational interpretive signs for a remnant prairie at the Lakewood Memorial Cemetery, Hinds County, Mississippi by Olivia Shelton A Thesis Submitted to the Honors College of The University of Southern Mississippi in Partial Fulfillment of Honors Requirements May 2019 ii Approved by _________________________________ Dr. Mac H. Alford, Ph.D. Thesis Adviser Professor of Biological Sciences _________________________________ Dr. Jake Schaefer, Ph.D., Director School of Biological, Environmental, and Earth Sciences _________________________________ Dr. Ellen Weinauer, Ph.D., Dean Honors College iii Abstract A floristic survey was conducted on the eastern margin of the Lakewood Memorial Park Cemetery, located between Jackson and Clinton, Mississippi, near the western edge of the Jackson Prairie ecoregion. From soil map data and preliminary observations of the landform and flora, the eastern part of the cemetery was hypothesized to be remnant prairie now mostly covered by exotic grasses (pasture) and woodland. Plant specimens were collected, identified, and preserved in the herbarium of The University of Southern Mississippi (USMS). The survey yielded 119 species of vascular plants, of which 98 (82%) were native and 21 (18%) were non- native. Indicative prairie plants included Anemone caroliniana (carolina anemone), Asclepias virdiflora (green milkweed), Echinacea purpurea (purple coneflower), Rudbeckia hirta (black- eyed susan), and Sorghastrum nutans (indian grass), and some of the associated woodland had rare species such as Carya myristiciformis (nutmeg hickory). Plants with a historical medical significance were also noted. Due to the scarcity of prairies in Mississippi, the landowners were petitioned to restore the prairie by burning and removal of non-native shrubs and trees and to place an educational interpretive sign about the prairies and the Jackson Prairie, in particular. Key Words: grasslands, Jackson Prairie, medicinal plants, prairie, prairie restoration iv Dedication This thesis is dedicated to Velda O. Moore. v Acknowledgments Thanks to Dr. Mac Alford for his constant support and encouragement and assistance with identification. Thanks to Bobby Harrell and the staff at Lakewood Memorial Cemetery for allowing us to study part of their property and to collect voucher specimens of plants found there.

Surveys of floras, or compiling a list of species in an area, are conducted for a variety of reasons, ranging from the search for a specific species, to the desire to better understand co-occurring species in plant communities, to the intention to provide a client with a list of the species present and gain a sense of a locality’s biodiversity. Mississippi has one of the least adequately known floras in the United States (Duncan, 1953; Bryson & Carter, 1996; Sorrie & Leonard, 1999; Majure, 2008), but a grant recently funded by the U.S. National Science Foundation to each of Mississippi’s plant collections (herbaria) has given the state an opportunity to revisit a draft checklist of plant species and to put images and data online for easier study (Mississippi Herbarium Consortium 2013; NSF 2018). A floristic survey was undertaken to gain insight into an area recently

Holmes [email protected] Department of Biology Baylor University Waco, Texas Identification of Milkweeds (Asclepias, Family Apocynaceae) in Texas Created in partnership with the Lady Bird Johnson Wildflower Center Design and layout by Elishea Smith Compiled by Jason Singhurst and Ben Hutchins [email protected] [email protected] Texas Parks and Wildlife Department Austin, Texas and Walter C. Holmes [email protected] Department of Biology Baylor University Waco, Texas Introduction This document has been produced to serve as a quick guide to the identification of milkweeds (Asclepias spp.) in Texas. For the species listed in Table 1 below, basic information such as range (in this case county distribution), habitat, and key identification characteristics accompany a photograph of each species. This information comes from a variety of sources that includes the Manual of the Vascular Flora of Texas, Biota of North America Project, knowledge of the authors, and various other publications (cited in the text). All photographs are used with permission and are fully credited to the copyright holder and/or originator. Other items, but in particular scientific publications, traditionally do not require permissions, but only citations to the author(s) if used for scientific and/or nonprofit purposes. Names, both common and scientific, follow those in USDA NRCS (2015). When identifying milkweeds in the field, attention should be focused on the distinguishing characteristics listed for each species.

In tracking populations of plant species of conservation concern (Missouri Natural Heritage Program, 2007), there are sometimes also boom years in the number of reports of new populations. Because of reports of five new populations and a surge in numbers of plants at some previously-known sites, 2007 provided encouraging news for the conservation of the auriculate false foxglove [Agalinis auriculata (Michx.)
