Thepark encompasses ca. 8,900 ha on the westernescarpment of the Cumberland Plateau. A total of881 taxa from131 familieswere documented during this survey. Of these taxa, 301 were determinedto becounty records for either VanBuren or Bledsoe County,Tennessee. Non-nativespecies arerepresented by 110 taxa, which is 12% ofthe total flora. Seventeen Federalor State listed taxa were documented, including Nestronia umbellula, which represents a physiographicrecord forthe CumberlandPlateau in Tennessee. Voucher specimens were deposited in the herbariumof the Universityof Tennessee (TENN). A total of 17 plantcommunities andeight microhabitats were delineated and describedduring this study. An analysisof distribution trends was conducted to assess geographic affinitiesof the flora. The majority of thetaxa (80%) lie withintheir distributionranges with therest either beingextraneous (4%), endemic (3%), or non-native (12%). A floristiccomparison was conducted to comparethe speciesrichness ofFCFSP to other previously surveyedareas on the CumberlandPlateau in Tennessee. This comparisondemonstrated that this parkhas the second highest richness value ofthose sites.

  • Pilgrimage Schedule
    43RD ANNUAL SPRING WILDFLOWER PILGRIMAGE MAY 04 - 06, 2012 CLAYTON, RABUN COUNTY, GEORGIA & ADJACENT AREAS Clayton, our headquarters for the 43rd Spring Wildflower Pilgrimage, is nestled in the Blue Ridge Mountains of northeast Georgia just a stone’s throw from the Carolinas. The Sumter National Forest is to the east, the Nantahala National Forest is to the north, and the Chattahoochee National Forest is all around Clayton. Some of Georgia’s highest mountains are but a short drive. A diverse group of interested persons from four or more states are expected to participate. The pilgrimage will consist of a Friday night social with a program and great food, a Saturday banquet with a special presentation program and more great food, and fantastic field trips to some very special places located in the region. Clayton and the surrounding area have a diversity of interesting shops that will entice you to shop for local arts, crafts, and foods. Clayton is the county seat for Rabun County, founded in 1819 from land formally inhabited by the Cherokee and named for Governor William Rabun. The 377 square miles of Rabun County comprise the most northeastern section of Georgia’s Blue Ridge Geographical Province, a region that encompasses a mere 5% of Georgia. Sixty percent of the county is public lands under the management of the US Forest Service or the Georgia Department of Natural Resources. This beautiful area of scenic valleys, high rugged mountains, clear streams, and lush forests is attractive year round, but offers a special floristic bounty each spring. Join the Georgia Botanical Society for the Annual Spring Wildflower Pilgrimage and share in this rich and beautiful bounty.

Rajapaksha1, C. de Alwis1 1Butterfly Conservation Society of Sri Lanka, 762/A, Yatihena, Malwana, Sri Lanka 2 E-mail: [email protected] Abstract Larval food plants (LFPs) of Sri Lankan butterflies are poorly documented in the historical literature and there is a great need to identify LFPs in conservation perspectives. Therefore, the current study was designed and carried out during the past decade. A list of LFPs for 207 butterfly species (Super family Papilionoidea) of Sri Lanka is presented based on local studies and includes 785 plant-butterfly combinations and 480 plant species. Many of these combinations are reported for the first time in Sri Lanka. The impact of introducing new plants on the dynamics of abundance and distribution of butterflies, the possibility of butterflies being pests on crops, and observations of LFPs of rare butterfly species, are discussed. This information is crucial for the conservation management of the butterfly fauna in Sri Lanka. Key words: conservation, crops, larval food plants (LFPs), pests, plant-butterfly combination. Introduction Butterflies go through complete metamorphosis 1949). As all herbivorous insects show some and have two stages of food consumtion.

  • Native Plants for Your Backyard
    U.S. Fish & Wildlife Service Native Plants for Your Backyard Native plants of the Southeastern United States are more diverse in number and kind than in most other countries, prized for their beauty worldwide. Our native plants are an integral part of a healthy ecosystem, providing the energy that sustains our forests and wildlife, including important pollinators and migratory birds. By “growing native” you can help support native wildlife. This helps sustain the natural connections that have developed between plants and animals over thousands of years. Consider turning your lawn into a native garden. You’ll help the local environment and often use less water and spend less time and money maintaining your yard if the plants are properly planted. The plants listed are appealing to many species of wildlife and will look attractive in your yard. To maximize your success with these plants, match the right plants with the right site conditions (soil, pH, sun, and moisture). Check out the resources on the back of this factsheet for assistance or contact your local extension office for soil testing and more information about these plants.

This challenge is most serious in tribe Caryophylleae since the supposed genera seem to be highly artificial, and the available morphological evidence cannot effectively be used for delimitation and exact determination of taxa. The main goal of the present study was to re-assess the monophyly of the genera currently recognized in this tribe using molecular phylogenetic data. We used the sequences of nuclear ribosomal internal transcribed spacer (ITS) and the chloroplast gene rps16 for 135 and 94 accessions, respectively, representing all 16 genera currently recognized in the tribe Caryophylleae, with a rich sampling of Gypsophila as one of the most heterogeneous groups in the tribe.

  • What Exactly Is a “Protected Plant?” CITES: Federal Endangered Species
    Orbis Environmental Consulting PO Box 10235 South Bend, IN 46680 574-635-1338 What Exactly is a “Protected Plant?” “Aren’t those protected?” “Trilliums are endangered, right?” Questions about laws pertaining to native plants are common among the environmental community and the broader public. The multitude of international, federal, and state laws, often differing in key details, can reinforce the seemingly esoteric nature of what, exactly, constitutes a “protected plant.” The following is a brief overview of pertinent laws including state- by-state lists of protected species in our immediate region (Illinois, Indiana, Michigan, and Ohio). CITES: CITES, or Convention on International Trade in Endangered Species of Wild Fauna and Flora, is an intergovernmental agreement to ensure that international trade in wild specimens of animals and plants does not threaten their survival. CITES is administered by the United Nations Environment Programme and, in the United States, the U.S. Fish and Wildlife Service. Listed species are assigned to one of three Appendices based on relative rarity and susceptibility to exploitation. CITES permits must be obtained for all international trade in these species. Learn more about CITES at cites.org. Federal Endangered Species Act: The Federal Endangered Species Act provides for the designation of a species as “endangered” if it is considered to be in danger of extinction throughout all or a significant portion of its range, or “threatened” if it is likely to become endangered. The Federal Endangered Species Act prohibits the following: • Import or export of endangered and threatened plants from the United States • Receipt, delivery, or sale of endangered and threatened plants in interstate or foreign commerce • Removal or malicious damage or destruction of endangered plants on federal lands.

  • Literature Cited
    Literature Cited Robert W. Kiger, Editor This is a consolidated list of all works cited in volumes 19, 20, and 21, whether as selected references, in text, or in nomenclatural contexts. In citations of articles, both here and in the taxonomic treatments, and also in nomenclatural citations, the titles of serials are rendered in the forms recommended in G. D. R. Bridson and E. R. Smith (1991). When those forms are abbre- viated, as most are, cross references to the corresponding full serial titles are interpolated here alphabetically by abbreviated form. In nomenclatural citations (only), book titles are rendered in the abbreviated forms recommended in F. A. Stafleu and R. S. Cowan (1976–1988) and F. A. Stafleu and E. A. Mennega (1992+). Here, those abbreviated forms are indicated parenthetically following the full citations of the corresponding works, and cross references to the full citations are interpolated in the list alphabetically by abbreviated form. Two or more works published in the same year by the same author or group of coauthors will be distinguished uniquely and consistently throughout all volumes of Flora of North America by lower-case letters (b, c, d, ...) suffixed to the date for the second and subsequent works in the set. The suffixes are assigned in order of editorial encounter and do not reflect chronological sequence of publication. The first work by any particular author or group from any given year carries the implicit date suffix “a”; thus, the sequence of explicit suffixes begins with “b”. Works missing from any suffixed sequence here are ones cited elsewhere in the Flora that are not pertinent in these volumes.
