Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- DIOSCOREACEAE Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- DIOSCOREACEAE DIOSCOREACEAE R. Brown 1810 (Yam Family) A family of about 3-20 genera and 600-880 species, of tropical and warm temperate regions. References: Raz in FNA (2002a); Huber in Kubitzki (1998a). Dioscorea Linnaeus 1753 (Yam) A genus of about 575-850 species, vines, of tropical and warm temperate regions of the Old World and New World. Huber in Kubitzki (1998a) advocates the division of the large and unwieldy Dioscorea into separate genera. Dioscorea (broadly defined) has a wide variety of economic uses, especially in the tropics, where it is most diverse. Various species are cultivated for their edible tubers (yams, not to be mistaken for sweet potatoes, Ipomoea batatas, often referred to colloquially as "yams" in the southern United States), especially in Africa. Oral contraceptives were developed from extracts of Dioscorea. Many other uses are described in Al-Shehbaz & Schubert (1989). References: Raz in FNA (2002a); Al-Shehbaz & Schubert (1989); Ward (1977c); Huber in Kubitzki (1998a). 1 Leaves halberd-shaped, the sides with a concave portion; aerial tubers often present in the leaf axils; plants perennial from large, vertically-oriented tubers; [non-native species, usually in disturbed areas, especially in bottomlands]; [section Enantiophyllum].........................................................................D. polystachya 1 Leaves cordate-ovate, the sides of the leaves continuously convex; aerial tubers never present; plants perennial from rhizomes; [native species, usually of forests and woodlands]; [section Macropoda]. 2 Staminate inflorescences usually of 1 large and 1-2 smaller secondary panicles in each axil (of upper stem leaves); filaments inwardly curved, ca. 0.4 mm long; anther lobes connate; tepals oblong; [ranging from SC south] . D. floridana 2 Staminate inflorescence a single panicle in each axil (of median or upper leaves); filaments straight, ca. 0.2 mm long; anther lobes separate; tepals ovate; [ranging more widely]. 3 Lower leaves in whorls of 4-7, upper leaves alternate; stem terete in cross-section; rhizomes 10-15 mm in diameter, often contorted and much-branched .................................................. D. quaternata 3 All leaves alternate (rarely the lowermost approximate, with short internodes, and appearing nearly whorled); stem polygonal in cross-section, with 8-14 narrowly-winged ribs; rhizomes 5-10 mm in diameter, usually relatively straight and little-branched. 4 Nodes and usually also internodes of the stem pubescent . D. villosa var. hirticaulis 4 Nodes and internodes of the stem glabrous . D. villosa var. villosa Dioscorea floridana Bartlett, Florida Wild Yam. Cp (GA, SC): mesic to dry forests, swampy forests; uncommon. June- July; August-November. D. floridana, "the most distinctive of North American species" (Al-Shehbaz & Schubert 1989), ranges from SC south to n. FL, in the Coastal Plain.

April-June; September-October. This species has been shown to be quite distinct from D. villosa. It has a more northern and montane range than D. villosa, ranging from NJ, NY, s. Ontario, WI, MN, and IA south to n. FL and LA, centered, and most abundant, in the Appalachians. The status of D. glauca requires further investigation (see Ward 1977).

Cp (GA, NC, SC, VA?): mesic soils of sandhill-pocosin ecotones, mesic forests; rare (NC Watch List). May-June; September-November. This variety ranges from s. NJ to GA, in the Coastal Plain. It is controversial whether this taxon deserves recognition, and, if so, at what level. While K and Al- Shehbaz & Schubert consider it a mere form of D. villosa, Ward (1977c) states that "a recent study at Duke University by Shu-fun Au, unfinished due to the death of its author, tentatively recognized D. hirticaulis and D. floridana but combined all other entities without distinction under D. villosa." Further study is needed. [= RAB, C; D. hirticaulis Bartlett -- F, G, S; D. villosa -- FNA, K, in part] Dioscorea villosa Linnaeus var. villosa, Common Wild Yam. Cp, Pd, Mt? (GA, NC, SC, VA): moist forests and woodlands; uncommon. April-June; September-November. The range of D. villosa var. villosa is apparently from MA and RI south to n. FL, primarily in the Coastal Plain. Al-Shehbaz & Schubert (1989) indicate that the lectotype of D. villosa has pubescent stems; nomenclatural changes are apparently needed, if varietal status of the 2 varieties here recognized proves warranted.

  • "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.

  • Weed Risk Assessment for Iris Pseudacorus L. (Iridaceae)
    Weed Risk Assessment for Iris United States pseudacorus L. (Iridaceae) – Yellow Department of flag iris Agriculture Animal and Plant Health Inspection Service September 24, 2013 Version 1 Left: Iris pseudacorus flower. Right: A colony of Iris pseudacorus (source: Bugwood, 2013). Agency Contact: Plant Epidemiology and Risk Analysis Laboratory Center for Plant Health Science and Technology Plant Protection and Quarantine Animal and Plant Health Inspection Service United States Department of Agriculture 1730 Varsity Drive, Suite 300 Raleigh, NC 27606 Weed Risk Assessment for Iris pseudacorus Introduction Plant Protection and Quarantine (PPQ) regulates noxious weeds under the authority of the Plant Protection Act (7 U.S.C. § 7701-7786, 2000) and the Federal Seed Act (7 U.S.C. § 1581-1610, 1939). A noxious weed is defined as “any plant or plant product that can directly or indirectly injure or cause damage to crops (including nursery stock or plant products), livestock, poultry, or other interests of agriculture, irrigation, navigation, the natural resources of the United States, the public health, or the environment” (7 U.S.C. § 7701-7786, 2000). We use weed risk assessment (WRA)— specifically, the PPQ WRA model (Koop et al., 2012)—to evaluate the risk potential of plants, including those newly detected in the United States, those proposed for import, and those emerging as weeds elsewhere in the world. Because the PPQ WRA model is geographically and climatically neutral, it can be used to evaluate the baseline invasive/weed potential of any plant species for the entire United States or for any area within it. As part of this analysis, we use a stochastic simulation to evaluate how much the uncertainty associated with the analysis affects the model outcomes.

  • Americus, Georgia
    July 2004 Rev. 1 Jimmy Carter Plant Materials Center Americus , Georgia WETLAND PLANTS SELECTED for CONSTRUCTED WETLANDS and STORMWATER SYSTEMS Wetland Plants Selected for Constructed Wetlands and Stormwater Systems From the Plant Materials Specialist Notebook This publication provides specific information on wetland plants for stormwater constructed wetlands. It contains recommendations for selection of wetland vegetation for stormwater management systems. The wetland plant technology was developed by the USDA Natural Resources Conservation Service; the Jimmy Carter Plant Materials Center in Americus, Georgia. The Jimmy Carter Plant Materials Center located in Americus, Georgia, has released `Restorer´ giant bulrush, Scirpus californicus and `Wetlander´ giant cutgrass, Zizaneopsis miliacea as new proven wetland native plant materials for constructed wetlands, and both are available from commercial nurseries. Stormwater wetlands perform by temporarily storing stormwater runoff in shallow pools that create favorable growing conditions for emergent and riparian wetland plants. The stormwater storage, contact area, microtopography, and the emergent plants together form an ideal matrix for the removal of pollutants normally associated with urban development. Emergent wetland vegetation such as, `Restorer´ giant bulrush, Scirpus californicus, Maidencane, Panicum hemitomon and blue flag iris, Iris versicolor, canna lily, canna spp, are quite attractive and provide adequate removal of contaminants. The use of constructed wetlands for stormwater quality control has attracted a great deal of attention. The 1987 amendments to the Clean Water Act focused attention on urban runoff. Stormwater (runoff) is the surface and ground water that results from precipitation. In developed areas, urban stormwater is the major component of sewer and stream flows. Stormwater runoff from parking lots, roofs, contains fertilizer, pesticides, animal waste, oil, grease, heavy metals, and other potential pollutants.

    Iris for the Home Gardener A Rainbow of Colors in Many Shapes and Sizes Bob Lyons FEW PLANTS HAVE AS MUCH HISTORY and affection among gardeners than iris. In Greek mythology, Iris is the personification of the rainbow and messenger of the Gods, and indeed, Iris appear in many magical colors—a large and diverse genus. Some have large showy flowers, others more I. ‘Black Gamecock’ understated; some grow in clumps, others spread; some prefer I. ensata ‘Angelic Choir’ it dry, others are more partial to moist, even wet conditions; and some grow from bulbs, while others return each year from rhizomes just beneath the soil surface. How does one tell them apart and make the right choice for a home garden? Fortunately, horticulturists and iris enthusiasts have developed a system of organization to make sense out of the vast world of irises. Three groups that account for more than 75% of the commercial iris market today are the Bearded Iris, Siberian Iris, and Japanese Iris. Each group recognizes the best of the best with prestigious national awards, noted in the descriptions that follow. The Dykes Medal is awarded to the finest iris of any class.

  • VESSELS in ERIOCAULACEAE By
    IAWA Journ al, Vol. 17 (2), 1996: 183-204 VESSELS IN ERIOCAULACEAE by Jennifer A. Thorsch & Vernon I. Cheadle I Department of Ecology, Evolution and Marine Biology, University of California, Santa Barbara, CA 93 106, U.S.A. SUMMARY The occ urrence and level of specialization of vesse ls in 70 species representing 12 genera of Eriocaulaceae are presented. In alI species of Eriocaulaceae and in alI parts of the plant examined, vessels with simple perforations have been identified . Correlations between level of specia­ lization of vessel members and ecological conditi ons are reported for species from diverse habitats and species with distinct differences in habit. The pattern of origin and specialization of tracheary celIs in Erio­ caulaceae was compared to tracheary data for Xyridaceae , Rapateaceae, Restionaceae and Centrolepidaceae. The evolutionary position of these families has been regarded as close to Eriocaulaceae. Key words: Eriocaulaceae, vessels, perforation plates, phylogenetic posi­ tion. INTRODUCTION This paper provides detailed information about perforation plates of vessels in Erio­ caulaceae, the 29th family we have similarly examined in monocotyledons. The near­ ly complete list of families analyzed in detail is given in the literature cited in the paper on Commelinales (Cheadle & Kosakai 1980). Our studies on the tracheary elements in monocotyledons have included families and species from a broad range of habits, habitats and geographical sites around the world. Families for study were selected based on three criteria: I) presence of alI plant parts, 2) variety of habits and habitats, and 3) broad representation of the species within the family. The data on tracheids and vessels from these broadly based studies led to the folIowing brief conclusions.
