Department of Planning and Zoning Subject: Howard County Landscape Manual Updates: Recommended Street Tree List (Appendix B) and Recommended Plant List (Appendix C) - Effective July 1, 2010 To: DLD Review Staff Homebuilders Committee From: Kent Sheubrooks, Acting Chief Division of Land Development Date: July 1, 2010 Purpose: The purpose of this policy memorandum is to update the Recommended Plant Lists presently contained in the Landscape Manual. The plant lists were created for the first edition of the Manual in 1993 before information was available about invasive qualities of certain recommended plants contained in those lists (Norway Maple, Bradford Pear, etc.). Additionally, diseases and pests have made some other plants undesirable (Ash, Austrian Pine, etc.). The Howard County General Plan 2000 and subsequent environmental and community planning publications such as the Route 1 and Route 40 Manuals and the Green Neighborhood Design Guidelines have promoted the desirability of using native plants in landscape plantings. Therefore, this policy seeks to update the Recommended Plant Lists by identifying invasive plant species and disease or pest ridden plants for their removal and prohibition from further planting in Howard County and to add other available native plants which have desirable characteristics for street tree or general landscape use for inclusion on the Recommended Plant Lists. Please note that a comprehensive review of the street tree and landscape tree lists were conducted for the purpose of this update, however, only -

The evolution of seeds, pollen, and wood freed plants from the need for water during reproduction, allowed for more effective dispersal of sperm, increased parental investment in the next generation and allowed for greater size and strength. 2. Seed plants originated in the Devonian period from a group called the progymnosperms, which possessed wood and heterospory, but reproduced by releasing spores. Currently, five lineages of seed plants survive--the flowering plants plus four groups of gymnosperms: cycads, Ginkgo, conifers, and gnetophytes. Conifers are the best known and most economically important group, including pines, firs, spruces, hemlocks, redwoods, cedars, cypress, yews, and several Southern Hemisphere genera. 3. The pine life cycle is heterosporous. Pollen strobili are small and seasonal. Each sporophyll has two microsporangia, in which microspores are formed and divide into immature male gametophytes while still retained in the microsporangia. -
Cyrtomium Falcatum, New to Tbe Italian Flora
Flora Mediterranea 3 - 1993 261 F. Bonafede, C. Ferrari & A. Vigarani Cyrtomium falcatum, new to tbe Italian flora Abstract Bonafede, F., Ferrari, C. & Vigarani, A. 1993: Cyrtomium falcatum, new to the Italian flora - Fl. Medil. 3: 261-264. 1993. - ISSN 1120-4052. The occurrence of a Cyrtomium falcatum population naturalized in the southem Po Valley (Emilia-Romagna region, Italy), is reported. This is the first record of the species for Italy, since all previous Italian findings of Cyrtomium belong to C. fortunei . The genus Cyrtomium C. PresI (Aspidiaceae) comprises about 20 species distributed mainly in the tropical and subtropical zones of Africa, America and Asia, in damp rocky habitats. Some authors include this genus in Polystichum on the basis of similarities in the morphology of the pinna and of the shield-shaped indusium. Cyrtomium falcatum (L. fil.) C. PresI is native to E. Asia and is cultivated as an omamental plant in Europe. Jalas & Suominen (1972), under the synonym Polystichum falcatum (L. fil.) Diels, report its being naturalized in Portugal and Great Britain, without giving further details of its European distribution. Badré & Deschatres (1979) include it among the French fem species as an alien naturalized near Nice. Specimens of Cyrtomium found in S. Switzerland near Brissago (Kramer in E. Pignatti & al) and in N. Italy (near Cannobio, in Lombardy, and on Mount Ragogna, in the Friuli Pre-Alps) alI to C. fortunei J. Sm. (S. Pignatti 1982; E. Pignatti & al. 1983), although the last-named one had at first been referred to as "e. falcatum" (Poldini 1980). The Cyrtomium population found by us grows on an old brick-walled well on a privately owned farm (P. -

A curbside crack in this study was defined as a linear space (under 20 mm in width) between the asphalt pavement and curbstone. The species composition of plants invading curbside cracks was surveyed in 38 plots along the serial National Route, over a total length of 36.5 km, in Fukuoka City in southern Japan. In total, 113 species including native plants (83 species, 73.5%), perennial herbs (57 species, 50.4%) and woody plants (13 species, 11.5%) were recorded in curbside cracks. Buried seeds were also obtained from soil in curbside cracks, which means the cracks would possess a potential as seed bank. Incidentally, no significant differences were found in the vegetation characteristics of curbside cracks among land-use types (Kolmogorov-Smirnov Test, P > 0.05). From these results, curbside cracks would be likely to play an important role in offering habitat for plants in urban area. -

Invasive Alien Plants an Ecological Appraisal for the Indian Subcontinent
Invasive Alien Plants An Ecological Appraisal for the Indian Subcontinent EDITED BY I.R. BHATT, J.S. SINGH, S.P. SINGH, R.S. TRIPATHI AND R.K. KOHL! 019eas Invasive Alien Plants An Ecological Appraisal for the Indian Subcontinent FSC ...wesc.org MIX Paper from responsible sources `FSC C013604 CABI INVASIVE SPECIES SERIES Invasive species are plants, animals or microorganisms not native to an ecosystem, whose introduction has threatened biodiversity, food security, health or economic development. Many ecosystems are affected by invasive species and they pose one of the biggest threats to biodiversity worldwide. Globalization through increased trade, transport, travel and tour- ism will inevitably increase the intentional or accidental introduction of organisms to new environments, and it is widely predicted that climate change will further increase the threat posed by invasive species. To help control and mitigate the effects of invasive species, scien- tists need access to information that not only provides an overview of and background to the field, but also keeps them up to date with the latest research findings. This series addresses all topics relating to invasive species, including biosecurity surveil- lance, mapping and modelling, economics of invasive species and species interactions in plant invasions. Aimed at researchers, upper-level students and policy makers, titles in the series provide international coverage of topics related to invasive species, including both a synthesis of facts and discussions of future research perspectives and possible solutions.

Pharmacology of Sinomenine, an Anti-Rheumatic Alkaloid from Sinomenium Acutum
Acta Medica Okayama Volume 30, Issue 1 1976 Article 1 FEBRUARY 1976 Pharmacology of sinomenine, an anti-rheumatic alkaloid from Sinomenium acutum Hidemasa Yamasaki∗ ∗Okayama University, Copyright c 1999 OKAYAMA UNIVERSITY MEDICAL SCHOOL. All rights reserved. Pharmacology of sinomenine, an anti-rheumatic alkaloid from Sinomenium acutum∗ Hidemasa Yamasaki Abstract The root and stem decoctions of Sinomenium acutum Rehd. et Wils. (formerly Sinomenium diversifolius Diels, one type of Fang-chi (Chinese)) have been used as a folk remedy for neuralgia and rheumatoid arthritis in many areas of the Far East. In Japan and China various viny plants have been identified as Fang-chi (Boi in Japanese) since antiquity. This uncertain nomenclature has made it difficult to evaluate the efficacy of the Fang-chi described in the classic literature. Among traditional Fang-chi plants only Sinomeniumacutum has been demonstrated to contain the alkaloid sinomenine, which is now known to be effective in neuralgia and rheumatic diseases. Sinomenine is a unique plant alkaloid, as it potently releases histamine in association with degran- ulation of tissue mast cells in mammalian tissues. This action occurs preferentially in the skin and joint capsules. The released histamine is responsible for the dominant pharmacological actions of sinomenine, such as vasodilatation, increased vascular permeability, acceleration of the thoracic and peripheral lymph flow, contraction of plain muscles, increased peristalsis of the intestines, and stimulation of gastric acid secretion. At toxic doses of sinomenine, convulsive central excita- tion was observed in most laboratory animals. Clinical side effects encountered with high doses of injected sinomenine or of decocted Sinomenium acutum were: injection site flare, pruritus in the head and upper part of the body, edema around the lips and eyelids, and temporary cephalal- gia. -
Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus). -
