Regeneration Traits of Celtis Sinensis Pers. and Aphananthe Aspera (Thunb.) Planch
Regeneration Traits of Celtis sinensis Pers. and Aphananthe aspera (Thunb.) Planch. in a Created Urban Tree Plantation approximately 20 years after construction Keizo TABATA* and Yukihiro MORIMOTO** Abstract： The groundbreaking example of creation of a tree plantation in an urban area is the “Inochi-No-Mori” project. The main goal of vegetation creation in Inochi-No-Mori is a deciduous broad-leaved forest dominated by Celtis sinensis and Aphananthe aspera. C. sinensis and A. aspera forests are thought to be the native vegetation of the Kyoto basin. For creation of C. sinensis and A. aspera plantations in urban areas, the promotion of natural regeneration of these two woody species is a necessity. To achieve this goal, an understanding of the growth characteristics of seedlings of these two species is required. To clarify the growth characteristics, recruitment, mortality and relative height growth rates of seedlings of C. sinensis and A. aspera in Inochi- No-Mori, we set up 163 quadrats (163 m2) on the forest floor of this tree plantation. As a result, there were no significance differences in mortality rates between two species. Recruitment rates of A. aspera seedlings, were relatively low. But low mortality and high growth rates were observed in this species. Although there were high recruitment rates in the C. sinensis seedlings, mortality rates were high and growth rates were relatively low. In a created urban tree plantation, the regeneration processes of the closely related species C. sinensis and A. aspera differed. Key Words： created urban tree plantation, growth characteristic, woody seedling succession. The main goal of vegetation creation in INTRODUCTION Inochi-No-Mori is a deciduous broad-leaved forest dominated by Celtis sinensis Pers.

THE PERFECT TREE Whether You Want a Leafy Canopy, Seasonal Fruit, Tactile Bark Or Visually Beautiful Blossoms, There Are Types of Trees to Fill These Functions
GARDENS THE PERFECT TREE Whether you want a leafy canopy, seasonal fruit, tactile bark or visually beautiful blossoms, there are types of trees to fill these functions TEXT MARY MAUREL Every garden needs a perfect tree. Depending on what type of tree it is, it can offer shade in the summer, provide autumnal leaf colour or seasonal flower colour, screen a neighbour’s house or even provide fruit in the summer. Or it could be that tree that defines a space: the tree in the lawn, deck or courtyard, with a gnarled form and a canopy overhead, which invites you outdoors and offers refuge. You can have just a tree and not much else around it, and yet this could be a perfect garden. We all have memories of such trees. One of my favourite trees is Ulmus parvifolia. Commonly known as a Chinese elm, it’s deciduous and a great tree for gardens where wind is an issue. Despite being tough, it has a lightness to its leafy canopy, offering dappled shade. It also has interesting bark. Trees for dappled shade Celtis africana, Ulmus parvifolia Trees for interesting bark Caesalpinia ferrea Trees for autumnal colour Liquidambar styraciflua Trees for screening Apodytes dimidiata, Curtisia dentata, Ilex mitis, Nuxia floribunda, Syzigium guineense.

Photo by Erfan Vafaie Article author: Erfan Vafaie, Mike Merchant, Mengmeng Gu Most recently reviewed by: Janet Hurley (2018) Common Name(s): crapemyrtle bark scale Description The crapemyrtle bark scale, Acanthococcus (=Eriococcus) lagerstromiae (Kuwana), was first confirmed in the USA in 2004 in the landscape near Dallas (TX), although it was likely introduced earlier. The scale is a sucking insect that feeds on the phloem (sap) of plants. As it feeds, it excretes a sugary solution known as “honeydew” (similar to aphids, whiteflies, and other sucking insects). Heavy infestations of crapemyrtle bark scale produce sufficient honeydew to coat leaves, stems and bark of the tree. This honeydew, in turn, will eventually 1/10 turn black as it is colonized by a concoction of fungi, called sooty mold. Although crapemyrtles rarely die as a result of crapemyrtle bark scale infestation, the sticky leaves and black trunks greatly reduce the attractive appearance of the tree. Immature crapemyrtle bark scale are hard to see with the naked eye, but adult scale covers and egg sacs are frequently visible on the upper branches and trunk of the tree. These scales include larger, white, oval (female) and smaller, elongate (male) scales. Both male and female scales of the crapemyrtle bark scale are immobile, and will “bleed” pink blood when crushed. Heavy infestation of crapemyrtle bark scale with sooty mold. Presence of ladybeetle pupa indicates some predation. Photo by Erfan Vafaie.

Accepted 14 September, 2010 Celtis sinensis Persoon and Celtis formosana Hayata belong to the Ulmaceae family. These closely related species are native to Taiwan. In the present study, 120 samples from 18 natural habitats in Taiwan were studied. The genetic diversity of these two species was determined by comparing the inter-simple sequence repeat (ISSR) and internal transcribed spacer (ITS) regions; these data were also used for the molecular identification of each species. Among the 71 bands amplified by PCR using nine ISSR primers, 51 exhibited polymorphism (71.8%). The population genetic variation analysis (POPGENE) revealed a genetic differentiation (Gst) of 0.3814 and a gene flow (Nm) of 0.8110. AMOVA showed that interspecies differences accounted for 57.38% of the variance (p < 0.0001). Despite their high morphological similarity, C. sinensis and C. formosana can be discriminated and classified into two independent species at the molecular level. Key words: Celtis , genetic diversity, molecular discrimination, inter-simple sequence repeat (ISSR), internal transcribed spacer (ITS).

Because of limited taxon and character sampling in previous studies, intergeneric phylogenetic relationships within this family have been poorly resolved. We conducted a molecular phylogenetic study based on four plastid loci (atpB-rbcL, rbcL, rps16, trnL-trnF) from 36 ingroup taxa, representing all ten recognized Cannabaceae genera, and six related taxa as outgroups. The molecular results strongly supported this expanded family to be a monophyletic group. All genera were monophyletic except for Trema, which was paraphyletic with respect to Parasponia. The Aphananthe clade was sister to all other Cannabaceae, and the other genera formed a strongly supported clade further resolved into a Lozanella clade, a Gironniera clade, and a trichotomy formed by the remaining genera.

Comparative Anatomical Studies of the Stem of Ulmaceous Plants in Taiwan
JOURNAL OF SCIENCE & ENGINEERING, MAY, 1966 VOL lII PP. 89~ 104 Comparative Anatomical Studies of the Stem of Ulmaceous Plants in Taiwan By L” Chun 吋u* Plant Anatomy Laboratory, Dept. of Botany Taiwan Provincial Chung Hsing University I In甜。duction It is generally, r會cognized by botanists that the structures of the plant body vary with their functions. In other words, plant anatomy is 扭timately related to plant pbysiology. It seems that early plant taxonomists did not pay much attention to anatomical characteristics of plants until cytologists and geneticists had ·recently made great contributions to the classification of lower plants. They therefore began emphasizing internal morphology as a factor in the classification cf higher plants. For the three species ·of Celtis cited in this paper, no distinct differences were found among them with regar.d to internal morphology. As for their external morphology, the items for classification also seemed quite meager. (This point will discussed later). So it was apparent that classifying plants solely on one aspe'ct of characteristics was not prudent. This paper was aimed at dissecting young stems of various plants to compare· the primary tissues in order to determine their natural taxonomic kinships. The author here offers his thanks to Prof. T. S. Liu, National Taiwan University, Prof. & Head of Dept. of Botany, S. T. Yi, Prof. Y. C. Liu, Taiwan Provincial Chung Hsing University, Prof. C. N. Chang, Taiwan Prov. agricultural Institute and Mr. C. Liu Taiwan Forestry Research Institute for their valuable assistance.

HPWRA FY18 Final Report HISC Prevention Working Group Continued Support of the HPWRA
HPWRA FY18 Final Report HISC Prevention Working Group Continued Support of the HPWRA Title: Continued Support of the HPWRA Organization: Hawaii‐Pacific Weed Risk Assessment (HPWRA) Award(s): $100,000.00 Introduction: The Hawaii‐Pacific Weed Risk Assessment (HPWRA) system is an internationally recognized screening tool that rates a plant’s potential to become invasive by answering 49 questions about its biology, ecology and history of invasiveness elsewhere. The answers generate a score that predicts a plant’s likelihood to be invasive in Hawaii or other tropical Pacific islands. For 17+ years, the HPWRA system has been an important tool for the promotion of responsible importation and planting decisions and has provided information necessary for preventing new invasive plant species from becoming unknowingly established and disseminated throughout the islands. The screening system addresses several goals and strategies developed by the 2015‐2020 strategic planning process and recommendations of the Regional Biosecurity Plan for Micronesia and Hawaii and increases the capacity and collaboration within the Prevention, Established Pests, and Public Outreach Working Groups. The HPWRA program is available to international, federal, state, and county agencies and private sectors to use as a preventative measure to assess the risk of introducing or planting a species in the country, state, or county. In accordance with these objectives, a Weed Risk Assessment Specialist has been funded by the Hawaii Invasive Species Council to the amount of $100,000 in 2018. Achievements in 2018 1. New or Revised Assessments Completed and Entered into the WRA Database: The HPWRA continues to provide new and to update old assessments, both for species already present in the Hawaiian Islands, as well as for new introductions.
