  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

  • Tracing History
    Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 911 Tracing History Phylogenetic, Taxonomic, and Biogeographic Research in the Colchicum Family BY ANNIKA VINNERSTEN ACTA UNIVERSITATIS UPSALIENSIS UPPSALA 2003 Dissertation presented at Uppsala University to be publicly examined in Lindahlsalen, EBC, Uppsala, Friday, December 12, 2003 at 10:00 for the degree of Doctor of Philosophy. The examination will be conducted in English. Abstract Vinnersten, A. 2003. Tracing History. Phylogenetic, Taxonomic and Biogeographic Research in the Colchicum Family. Acta Universitatis Upsaliensis. Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 911. 33 pp. Uppsala. ISBN 91-554-5814-9 This thesis concerns the history and the intrafamilial delimitations of the plant family Colchicaceae. A phylogeny of 73 taxa representing all genera of Colchicaceae, except the monotypic Kuntheria, is presented. The molecular analysis based on three plastid regions—the rps16 intron, the atpB- rbcL intergenic spacer, and the trnL-F region—reveal the intrafamilial classification to be in need of revision. The two tribes Iphigenieae and Uvularieae are demonstrated to be paraphyletic. The well-known genus Colchicum is shown to be nested within Androcymbium, Onixotis constitutes a grade between Neodregea and Wurmbea, and Gloriosa is intermixed with species of Littonia. Two new tribes are described, Burchardieae and Tripladenieae, and the two tribes Colchiceae and Uvularieae are emended, leaving four tribes in the family. At generic level new combinations are made in Wurmbea and Gloriosa in order to render them monophyletic. The genus Androcymbium is paraphyletic in relation to Colchicum and the latter genus is therefore expanded.

  • Perennials in the Landscape
    Perennials in the Landscape Home gardeners and commercial landscapers alike are becoming more aware of the rich potential hardy herbaceous perennials have to offer. Perennials just may be the most overlooked group of landscaping plants in our area, and for no good reason. They offer a certain permanency to the landscape, and are virtually unequaled in providing abundant color and interest in return for the care they require. Botanically, perennials are plants which live for more than two years. This, of course, would include trees, turf grasses and shrubs. Horticulturally, though, the term perennial refers to a group of herbaceous (nonwoody) plants most frequently grown for their colorful flowers. Plants possessing bulbs and bulblike structures (corms, tubers, etc.) technically belong to this group, and are often included with them. More frequently they are separated off into their own category, though the dividing line is often blurred. Perennials have probably been under utilized in the South because of a general assumption that they don't do well here. Many perennials, however, thrive under our growing conditions. Just make sure you exercise care in choosing varieties suitably adapted to your situation. Most perennials are completely winter-hardy in the Southeast, although there are a number of tender perennials grown in the Gulf Coastal areas which would not be suitable in areas with colder winters. Conversely, some perennials like peonies do better where winters are colder. Overall, the major limiting factors for tolerance and susceptibility to diseases favored by heat and humidity. When selecting perennials, you should tend toward those with a reputation for heat tolerance.

  • Vascular Flora and Vegetation Classification of the South Atlantic Coastal Plain Limestone Forest Association of Central Georgia
    VASCULAR FLORA AND VEGETATION CLASSIFICATION OF THE SOUTH ATLANTIC COASTAL PLAIN LIMESTONE FOREST ASSOCIATION OF CENTRAL GEORGIA by PATRICK SUMNER LYNCH (Under the Direction of J.L. Hamrick) ABSTRACT The South Atlantic Coastal Plain Limestone forest is a globally imperiled (G2) forest association known only from the upper Coastal Plain of central Georgia. These calcareous forest communities support diverse floristic assemblages unique among the Georgia Coastal Plain, but have not been subject to detailed floristic study. I conducted a comprehensive floristic inventory, multivariate community analyses and floristic quality assessments to document composition, elucidate community structure and underlying physiographic regimes, and assess habitat integrity for seven sites in Houston, Bleckley and Twiggs counties. Community analyses revealed twelve community types within two floristically defined domains corresponding to uplands and slopes, and bottomlands, respectively, and governed largely by moisture content and degree of inclination. Floristic quality assessments revealed varying degrees of floristic quality and habitat integrity corresponding primarily to local physiography and disturbance history. Floristic inventory recovered 339 vascular plant taxa representing 218 genera in 98 families, including 17 rare Georgia species.

In this plan, we will briefly introduce the physical and biological setting, past land use, and current uses of the Domain. The remainder of the plan consists of an assessment of the forest, which has been divided into six conservation areas. These conservation areas contain multiple management compartments, and the six areas have similarities in topographical position and past land use. Finally, the desired future condition and project summary of each conservation area and compartment has been outlined. Background The University of the South consists of an academic campus (382 acres) with adjacent commercial and residential areas (783 acres) that are embedded within and surrounded by diverse natural lands (11,838 acres). The term “Domain” is used interchangeably to describe both the entire ~13,000 acres and the 11,800-acre natural land matrix (also referred to as the “Greater Domain”).

  • Scarlet Hibiscus (Hibiscus Coccineus)
    Scarlet hibiscus (Hibiscus coccineus) For definitions of botanical terms, visit en.wikipedia.org/wiki/Glossary_of_botanical_terms. Scarlet hibiscus (also known as Scarlet rosemallow) is an herbaceous to semi-woody perennial wildflower that is common along wetland and stream edges, and in swamps and other wet, open sites. In late summer, it produces large, crimson blooms that remain open for only one day. Scarlet rosemallow is a profuse bloomer, however, and will typically produce many flowers throughout the summer. The plant is a larval host for several butterflies and moths including the Painter lady and Tropical checkered skipper butterflies and the Io moth. The flowers are very attractive to hummingbirds, butterflies and other pollinators. Scarlet hibiscus flowers are large (4 to 8 inches in Photo by Stacey Matrazzo diameter) with five bright red petals, a five-lobed green calyx, and linear bracts. Flowers are born in leaf axils. Leaves are glabrous, palmate and deeply lobed with long petioles. Margins are toothed, and leaf arrangement is alternate. Stems and petioles may be reddish. Seeds are born in ovoid five-celled capsules. Each cell may contain many seeds. The genus name Hibiscus is from the Greek hibiskos, or “mallow.” The species epithet coccineus is from the Greek kókkinos, meaning “scarlet red.” Family: Malvaceae (Mallow family) Native range: Eastern Panhandle, north and central peninsula, Collier, Broward and Okaloosa counties To see where natural populations of Scarlet hibiscus have been vouchered, visit www.florida.plantatlas.usf.edu. Hardiness: Zones 8A–11 Lifespan: Perennial Soil: Moist to wet or inundated, rich soils; can be acclimated to well-drained soils with enough moisture Exposure: Full sun to partial shade Growth habit: 3–7’+ tall with 2–5’ spread Propagation: Seeds, cuttings Garden tips: Scarlet hibiscus is one of our showiest native wildflowers.
