The Status of Fraxinus Papillosa (Oleaceae): Sem Study of Epidermal Features 14 LUNDELLIA DECEMBER, 2010 THE STATUS OF FRAXINUS PAPILLOSA (OLEACEAE): SEM STUDY OF EPIDERMAL FEATURES Justin K. Williams1 and Guy L. Nesom2 1Department of Biological Sciences, Sam Houston State University, Huntsville, TX 77341-2116 22925 Hartwood Drive, Fort Worth, TX 76109, USA www.guynesom.com Abstract: The abaxial leaf surfaces of Fraxinus in the southwestern USA and northwestern Mexico are sometimes white-glaucous and have been describedas ‘‘papillose.’’ Individuals exhibiting this morphology have been identified as F. papillosa, a species reported from Arizona, New Mexico, Texas, and Mexico. In the original description of F. papillosa, its leaf epidermal structure was compared to F. americana L., but the abaxial surface morphology of F. papillosa is distinctly different from that of F. americana. In the latter, a cuticular reticulum overlays the epidermis and partially obscures it, while the abaxial surface of F. papillosa is similar to that of F. velutina in its lack of a cuticular overlay. In F. papillosa each epidermal cell is abruptly convex or folded upward into a papilla-like structure, compared to the relatively flat-surfaced cells of F. velutina—intergradation occurs but whether the two are appropriately considered conspecific remains to be determined. SEM photographs of the abaxial leaf surface morphology of F. papillosa, F. velutina, and other species that are similar to F. papillosa are provided.

  • "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.

  • Oystershell Scale (Lepidosaphes Ulmi) on Green Ash (Fraxinus Pennsylvanica)
    Esther Buck(Senior) Oystershell Scale (Lepidosaphes ulmi) on Green Ash (Fraxinus pennsylvanica) I found a green ash tree (Fraxinus pennsylvanica) outside the law building that was covered with Oystershell Scale, (Lepidosaphes ulmi). Oystershell Scale insects on Green Ash twig Oystershell Scale insects The Green Ash normally has an upright oval growth habit growing up to 50ft tall. The Green Ash that I found was only about 20ft tall. The tree also had some twig and branch dieback. The overall health of the plant was fair, it was on the shorter side and did have some dieback but it looked like it could last for a while longer. The dwarfed growth and dieback of branches and twigs was probably a result of the high infestation of Oystershell Scale (Lepidosaphes ulmi) insect on the branches of the tree. Scale insects feeding on plant sap slowly reduce plant vigor, so I think this sample may have been shorter due to the infestation of Scale insects. As with this tree, heavily infested plants grow poorly and may suffer dieback of twigs and branches. An infested host is occasionally so weakened that it dies. The scale insects resemble a small oyster shell and are usually in clusters all over the bark of branches on trees such as dogwood, elm, hickory, ash, poplar, apple etc. The Oystershell Scale insect has two stages, a crawler stage, which settles after a few days. Then the insect develops a scale which is like an outer shell, which is usually what you will see on an infested host. The scales are white in color at first but become brown with maturity.

  • Asian Long-Horned Beetle Anoplophora Glabripennis
    MSU’s invasive species factsheets Asian long-horned beetle Anoplophora glabripennis The Asian long-horned beetle is an exotic wood-boring insect that attacks various broadleaf trees and shrubs. The beetle has been detected in a few urban areas of the United States. In Michigan, food host plants for this insect are abundantly present in urban landscapes, hardwood forests and riparian habitats. This beetle is a concern to lumber, nursery, landscaping and tourism industries. Michigan risk maps for exotic plant pests. Other common name starry sky beetle Systematic position Insecta > Coleoptera > Cerambycidae > Anoplophora glabripennis (Motschulsky) Global distribution Native to East Asia (China and Korea). Outside the native range, the beetle infestation has been found in Austria and Canada (Toronto) and the United States: Illinois (Chicago), New Jersey, New York (Long Island), and Asian long-horned beetle. Massachusetts. Management notes Quarantine status The only effective eradication technique available in This insect is a federally quarantined organism in North America has been to cut and completely destroy the United States (NEPDN 2006). Therefore, detection infested trees (Cavey 2000). must be reported to regulatory authorities and will lead to eradication efforts. Economic and environmental significance Plant hosts to Michigan A wide range of broadleaf trees and shrubs including If the beetle establishes in Michigan, it may lead to maple (Acer spp.), poplar (Populus spp.), willow (Salix undesirable economic consequences such as restricted spp.), mulberry (Morus spp.), plum (Prunus spp.), pear movements and exports of solid wood products via (Pyrus spp.), black locust (Robinia pseudoacacia) and elms quarantine, reduced marketability of lumber, and reduced (Ulmus spp.).

  • Emerald Ash Borer Coleoptera: Buprestidae Current Rating: None Proposed Rating: A
    CALIFORNIA DEPARTMENT OF cdfa FOOD & AGR I CULT URE ~ California Pest Rating Proposal Agrilus planipennis Fairmaire: Emerald ash borer Coleoptera: Buprestidae Current Rating: None Proposed Rating: A Comment Period: 01/25/2021 – 03/11/2021 Initiating Event: On January 14, 2021, the United States Department of Agriculture removed the federal domestic quarantine for emerald ash borer, a pest that is not known to be present in California. It was determined that the resources currently being used for this quarantine would be more effective if directed towards biological control. Emerald ash borer has not been rated. Therefore, a pest rating proposal is needed. History & Status: Background: Adult emerald ash borers reach 14 mm in length and are narrow and metallic blue-green in color. The larvae are white and flattened and reach 32 mm in length (Center for Plant Health Science and Technology). Adult emerald ash borers feed on leaves (including those of ash (Fraxinus spp.) and white fringetree (Chionanthus virginicus), although this is not reported to cause significant damage (Peterson, 2019). Eggs are laid on tree branches or trunks from 2.5 to more than 90 cm diameter (McCullough, 2019). The larvae tunnel into and feed on phloem and outer sapwood. The feeding damage causes dieback and eventual death (in as little as two years) of the tree (United States Department of Agriculture, -- CALIFORNIA DEPARTMENT OF cdfa FOOD & AGRICULTURE ~ 2018). Adult emergence holes have a characteristic D-shape (Center for Plant Health Science and Technology). Development requires one to two years depending on climate; the larva is the overwintering stage in both cases (Herms and McCullough, 2014).

  • Arboretum Guide 2.Pmd
    Acknowledgments An arboretum is a place for the study, display and preservation of trees. Thanks to the foresight and devotion of members of the Guada Coma Garden Club, Landa Park was designated as an arboretum in 1982. Nestled on 51 acres of river front park land, this arboretum acts as a living library of trees. Developed by Harry Landa in 1898 as a private park, Landa Park was opened to the public in 1936. Since that time, residents have worked to preserve the natural beauty that exists here. The arboretum was named after two such individuals, William and Delores Schumann, in 2007 in honor of their endless devotion to this botanical jewel.
