Non-Native Trees and Large Shrubs for the Washington, D.C. Area

AREA Non-native trees are some of the most beloved plants in the landscape due to their beauty. In addition, these trees are grown for the shade, screening, structure, and landscape benefits they provide. Deciduous trees, whose leaves die and fall off in the autumn, are valuable additions to landscapes because of their changing interest throughout the year. Evergreen trees are valued for their year-round beauty and shelter for wildlife. Evergreens are often grouped into two categories, broadleaf evergreens and conifers. Broadleaf evergreens have broad, flat leaves. They also may have showy flowers, such as Camellia oleifera (a large shrub), or colorful fruits, such as Nellie R. Stevens holly. Coniferous evergreens either have needle-like foliage, such as the lacebark pine, or scale-like foliage, such as the green giant arborvitae. Conifers do not have true flowers or fruits but bear cones. Though most conifers are evergreen, exceptions exist. Dawn redwood, for example, loses its needles each fall. The following are useful definitions: Cultivar (cv.) - a cultivated variety designated by single quotes, such as ‘Autumn Gold’. A variety (var.) or subspecies (subsp.), in contrast, is found in nature and is a subdivision of a species (a variety of Cedar of Lebanon is listed). Full Shade - the amount of light under a dense deciduous tree canopy or beneath evergreens. Full Sun - at least 6 hours of sun daily. -

Plant Lover’s Almanac Jim Chatfield Ohio State University Extension For: March 31, 2018 AcerMania. AcerPhilia. The crazy love of one of our greatest group of trees. Maples. From maple syrup to maple furniture. From musical instruments due to their tone-carrying trait to a wondrous range of landscape plants. Here are a few queries about maples I have received recently and a few rhetorical questions I have added to the mix for proper seasoning. Q. – Which maples are used to make maple syrup? A. – How topical. The obvious answer is sugar maple, Acer saccharum, with sweetness of the sap sewn into its Latin name. Silver maple is also sometimes used, and its Latin name, Acer saccharinum, suggests this is so. Black maple, Acer nigrum, is commonly used and it is so closely-related to sugar maple that it is often considered a sub-species. Box elder, Acer negundo, is also used somewhat in Canada, but to me one of the most surprisingly tapped maples, increasing in popularity in Ohio is red maple, Acer rubrum. Its sap is less sweet but red maple sugar-bushes are easier to manage. Q. Where does the name “Ácer” come from? A. The origins are somewhat obscure, but one theory is that its roots mean “sharp”, which if true would relate to the pointed nature of the leaf lobes on many maples. As a Latin genus name, Acer has over 120 species worldwide, with only one in the southern hemisphere. Q. – Which maples are native to the United States? A. - Five are familiar to us here in the northeastern U.S., namely sugar maple, red maple, silver maple, striped maple and box elder. -

2017-4 Winter Newsletter Wespelaar Maple Collection No
Reprinted from: The Maple Society Newsletter, Winter 2017 Vol 27/4 The Maple Collection at Arboretum Wespelaar, Belgium, with a special focus on some of the newer and rarer additions By Koen Camelbeke, Director, Arboretum Wespelaar It is indeed safe to say that the first dendrological passion of the founder of Arboretum Wespelaar, Philippe de Spoelberch, was for the genus Acer and rightly so! As we all know, this genus is really a joy at all times of year: flowers; new growth; colour and texture of emerging leaves in the Spring; variation in form and colour of leaves in the View across the lake at Arboretum Wespelaar, July 2013. Summer; autumn (Photo: Keith Montgomery) colours from late September to the end of November; and finally, the amazing range of bark textures and general tree habit which grace the winter months. When the Arboretum collection was started in the mid-1980s, the focus was on both botanical diversity as well as on aesthetics, especially focusing on autumn colour and Japanese maples. In the last decade or so, the focus shifted gradually to plants of known wild origin with the aim to present all of the species hardy in Belgium. Belgium is in this respect a wonderful country. Of course, as everywhere else, we also try to grow taxa which are more borderline in our climate, but, speaking of maples, Belgium has an excellent temperate, maritime climate influenced by the North Sea and Atlantic Ocean. Wespelaar is about 130km from the coast which means that our winters are somewhat colder and our summers hotter compared to the west of the country. -

State of Oregon The ORE BIN Department of Geology Volume 35, No.3 and Mineral Industries 1069State Office Bldg. March 1973 Portland Oregon 97201 THE OLIGOCENE LYONS FLORA OF NORTHWESTERN OREGON Herb Meyer Student, Portland State University The purpose of this study of the Lyons flora is to determine the age and paleoecology of the flora through the examination and identification of the fossil plant species of the flora. The plant fossi Is comprising the Lyons flora were collected from a locality in the .t~~·fi:~ora upper Thomas Creek area, 5 mi les sou theast of the town of Lyons, Oregon. Geologic Occurrence The beds from which the Lyons flora was obtained are part of the Little Butte Volcanic Series of Oligocene and early Miocene age described by Peck and others(1964). Stratigraphically below the fossil deposit, the Little Butte Volcanic Series is characterized by a pumiceous tuff-breccia which contains blocks and fragments of a volcanic flow rock. This exposure, the base of which is not exposed, underlies the fossil deposit for a thickness of more than 400 feet. The deposit containing the fossi I leaves is composed of a thinly lami nated tuffaceous material which has been silicifed to varying degrees. These beds may have been deposi ted in a sha !low, quiet body of water. Lacustrine deposition is suggested by the stratification of the beds, the abundant pres ence of fossil leaves, and the presence of one water plant in the fossil record. Composition of the Lyons Flora Twenty-four identified fossi I plants represent the Lyons flora as it is known at this point in the study. -

Early Oligocene Plant Diversity Along the Upper Rhine Graben: the Fossil Flora of Rauenberg, Germany
Acta Palaeobotanica 56(2): 329–440, 2016 DOI: 10.1515/acpa-2016-0011 Early Oligocene plant diversity along the Upper Rhine Graben: The fossil flora of Rauenberg, Germany JOHANNA KOVAR-EDER State Museum of Natural History Stuttgart, Rosenstein 1, 70191 Stuttgart, Germany; e-mail: [email protected] Received 11 July 2016; accepted for publication 7 October 2016 ABSTRACT. The macroflora of Rauenberg, Baden-Württemberg, Germany, is treated monographically. The plant-bearing sediments are marine, mainly well-bedded clay- to siltstones, the so-called Fischschiefer, which are part of the Bodenheim Formation. Based on nannoplankton they are dated to nannoplankton zone NP 23 (Rupelian, Lower Oligocene). The plant remains, mainly leaves and some fructifications, are preserved as compressions. The taxonomic assignment is based on gross morphology and cuticle characteristics. The flora yields marine algae and remains of the very diverse terrestrial flora. A total of 68 taxa, including three types of algae, one cycad, 12 conifers, and 49 dicots, among them 5 palms, are described. The following fossil spe- cies are described for the first time: Laurophyllum rauenbergense, Myrica obliquifolia, Distylium metzleri, ? Berchemia altorhenana, ? Ternstroemites maritiae, Trachelospermum kelleri, Oleinites altorhenana, O. rauen- bergensis, Dicotylophyllum badense, D. oechsleri, D. vesiculaeferens, D. ziegleri, ? Viscophyllum hendriksiae, and Cladites vesiculaeferens. Dicotylophyllum vesiculaeferens and Cladites vesiculaeferens bear peculiar, complex cuticular structures presumably representing salt-secreting glands. Both taxa are interpreted to derive from one plant species of yet uncertain systematic affinity. The flora bears a high proportion of broad-leaved, presum- ably evergreen taxa, whereas the diversity of modern Arcto-Tertiary taxa (sensu Kvaček 1994) is rather low.
