Science, Sentiment and Territorial Chauvinism in the Acacia Name Change Debate
9 Science, sentiment and territorial chauvinism in the acacia name change debate Christian A. Kull School of Geography and Environmental Science, Monash University, Clayton, Victoria [email protected] Haripriya Rangan Monash University, Clayton, Victoria Introduction The genus Acacia, as Peter Kershaw has often told us, may be widely present in the landscape, but its pollen is seldom found in any abundance. The pollen grains are heavy and probably not capable of long-distance transport, and even where they dominate the vegetation, their pollen is greatly under-represented. Compounding the problem, Acacia pollen tends to break up into individual units that are difficult to identify. However, as we hope to show in our contribution celebrating Peter’s work, the poor representation of acacias in palaeoenvironmental records is more than compensated by its dominating presence in what has been described as one of the longest running, most acrimonious debates in the history of botanical nomenclature (Brummitt 2011). Few would imagine botanical nomenclature to be a hotbed of passion and intrigue, but the vociferous arguments and machinations of botanists regarding the rightful ownership of the Latin genus name Acacia give an extraordinary insight into the tensions that arise when factors such as aesthetic judgement, political clout and nationalist sentiments dominate the process of scientific classification. After much lobbying and procedural wrangling, on July 16, the last day of the 2005 International Botanical Congress in Vienna, botanists approved a decision to allow an exception to the nomenclatural ‘principle of priority’ for the acacia genus. With increasing demand by botanists to split apart the massive cosmopolitan and paraphyletic genus into several monophyletic genera, the Vienna decision conserved the name acacia for the members of the new genus from Australia.

Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt
plants Article Synoptic Overview of Exotic Acacia, Senegalia and Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) in Egypt Rania A. Hassan * and Rim S. Hamdy Botany and Microbiology Department, Faculty of Science, Cairo University, Giza 12613, Egypt; [email protected] * Correspondence: [email protected] Abstract: For the first time, an updated checklist of Acacia, Senegalia and Vachellia species in Egypt is provided, focusing on the exotic species. Taking into consideration the retypification of genus Acacia ratified at the Melbourne International Botanical Congress (IBC, 2011), a process of reclassification has taken place worldwide in recent years. The review of Acacia and its segregates in Egypt became necessary in light of the available information cited in classical works during the last century. In Egypt, various taxa formerly placed in Acacia s.l., have been transferred to Acacia s.s., Acaciella, Senegalia, Parasenegalia and Vachellia. The present study is a contribution towards clarifying the nomenclatural status of all recorded species of Acacia and its segregate genera. This study recorded 144 taxa (125 species and 19 infraspecific taxa). Only 14 taxa (four species and 10 infraspecific taxa) are indigenous to Egypt (included now under Senegalia and Vachellia). The other 130 taxa had been introduced to Egypt during the last century. Out of the 130 taxa, 79 taxa have been recorded in literature. The focus of this study is the remaining 51 exotic taxa that have been traced as living species in Egyptian gardens or as herbarium specimens in Egyptian herbaria. The studied exotic taxa are accommodated under Acacia s.s. (24 taxa), Senegalia (14 taxa) and Vachellia (13 taxa).

AND Eucalyptus nicholii Ermelinda Silva1, Sara Fernandes1, Eunice Bacelar1 , Ana Sampaio1* 1Department of Biology and Environment (DeBA), UTAD, Quinta dos Prados, 5001-801 Vila Real, Portugal Corresponding author E-mail: [email protected] Abstract Background: In Europe, Acacia and Eucalyptus, originate large amounts of biomass, due to their need by industries and other biological control, that can be used to extract antimicrobial substances. Materials and Methods: Foliar aqueous, ethanolic and methanolic extracts of Acacia baileyana (Cootamundra wattle), Acacia dealbata (silver wattle), Acacia melanoxylon (black wattle) and Eucalyptus nicholii (narrow-leaved black peppermint) were assessed for antimicrobial activity against Escherichia coli, Bacillus cereus, Candida albicans and Candida parapsilosis, using the disc diffusion method. Results: Ethanolic extracts from A. baileyana and A. dealbata showed significant (P< 0.05) antimicrobial activity. Concerning the microbial species tested, differences were found in A. baileyana (P< 0.01) and E. nicholii (P< 0.0001) extracts. These two extracts were effective mostly against B. cereus, followed by C. parapsilosis. According to the antimicrobial activity classification, eucalypt and Cootamundra and silver wattles extracts (both water and ethanol) presented good efficacy against B. cereus, a food poisoning agent, and moderate efficacy against the remaining microorganisms. E. coli, a Gram negative, exhibited low sensibility to all foliar extracts. Conclusion: A. baileyana, E. nicholii and A. dealbata foliar biomass could be used to develop alternative substances in microbial control. Key words: foliar extracts, Acacia, Eucalyptus nicholii, anti-microbial activity Introduction Plants have acquired effective defense mechanisms that ensure their survival under adverse conditions.

ABSTRACT the First Through Fifth Instars of the Gypsy Moth Were Tested for Development to Adults on 326 Species of Dicotyledonous Plants in Laboratory Feeding Trials
LABORATORY FEEDING TESTS ON THE DEVELOPMENT OF GYPSY MOTH LARVAE WITH REFERENCE TO PLANT TAXA AND ALLELOCHEMICALS JEFFREY C. MILLER and PAUL E. HANSON DEPARTMENT OF ENTOMOLOGY, OREGON STATE UNIVERSITY, CORVALLIS, OREGON 97331 ABSTRACT The first through fifth instars of the gypsy moth were tested for development to adults on 326 species of dicotyledonous plants in laboratory feeding trials. Among accepted plants, differences in suitability were documented by measuring female pupal weights. The majority of accepted plants belong to the subclasses Dilleniidae, Hamamelidae, and Rosidae. Species of oak, maple, alder, madrone, eucalyptus, poplar, and sumac were highly suitable. Plants belonging to the Asteridae, Caryophyllidae, and Magnoliidae were mostly rejected. Foliage type, new or old, and instar influenced host plant suitability. Larvae of various instars were able to pupate after feeding on foliage of 147 plant species. Of these, 1.01 were accepted by first instars. Larvae from the first through fifth instar failed to molt on foliage of 151 species. Minor feeding occurred on 67 of these species. In general, larvae accepted new foliage on evergreen species more readily than old foliage. The results of these trials were combined with results from three previous studies to provide data on feeding responses of gypsy moth larvae on a total of 658 species, 286 genera, and 106 families of dicots. Allelochemic compositions of these plants were tabulated from available literature and compared with acceptance or rejection by gypsy moth. Plants accepted by gypsy moth generally contain tannins, but lack alkaloids, iridoid monoterpenes, sesquiterpenoids, diterpenoids, and glucosinolates. 2 PREFACE This research was funded through grants from USDA Forest Service cooperative agreement no.

Aliens from the Garden
ALIENS FROM THE GARDEN Libby Robin1,3, Joslin Moore2,5, Sharon Willoughby2, Sara Maroske5,2 1Australian National University, Canberra, Australia, 2Royal Botanic Gardens, Melbourne, Australia, 3National Museum of Australia, Canberra, Australia, 4Royal Institute of Technology (KTH), Stockholm, INTRODUCTION Aesthetic choices made historically by urban gardeners shape Australia’s environment today. In this new project we are using a history of urban garden tastes to understand the emerging phenomenon of environmental weeds. Principally we focus on garden plants that threaten the ecological functioning of Australian bushland, but we are putting this in the context of the changing history of garden aesthetics more generally, since a gardener’s wider environmental sensibilities may be at odds with choices made when selecting plants for a private garden. Because Australia is a highly urbanised place, the vast majority of gardens are in cities and reflect the taste, values and objectives of city-dwellers. George Seddon has commented that gardeners are ‘one of the most important groups of land managers in this country, … [managing] more than 50 per cent of all urban land in Australia’. (Seddon 1997: 183) The impact of urban gardens can be felt well beyond city limits. Those hardy plants that enliven the urban landscape have often been chosen as ‘survivors’. It is just such survivors that can become invasive weeds in the Australian bush. Because they have been identified as hardy, they are welcomed as successful by gardeners, but over the fence, in the Australian bush they seriously limit the opportunities for other plants, and ultimately compromise biodiversity in the bush. Plants chosen for gardens now account for 69% of agricultural weeds and 72% of environmental weeds.

Cootamundra Wattle (Acacia Baileyana)
Source: http://www.esc.nsw.gov.au/living-in/about/our-natural-environment/introduced-plants-and- animals/weeds/weed-profiles/cootamundra-wattle-acacia-baileyana (Downloaded 30/10/2015) Cootamundra wattle (Acacia baileyana) Family: Fabaceae (Mimosoidae) - wattles Status: Australian native, but invasive outside its natural range. Description: A small evergreen tree to 3-4m high. Leaves are compound, with many tiny silvery-grey leaflets. One form has purple new growth. Flowers are clusters of fluffy yellow balls produced in winter, and the black shiny seeds are carried in flat brown papery pea-like pods. Preferred habitat and impacts: Cootamundra wattle is a native of a small area between Cootamundra and Temora in NSW, but it has been very widely planted because of its attractive foliage It is now naturalised in many parts of Australia. It has also hybridised with other wattles. It is usually seen on road verges and in drier bush close to towns and gardens, where it can replace local native shrubs and shade out native grasses and wildflowers. It is short-lived, and creates a mess when it dies and collapses. All wattles produce large crops of hard-coated seed which can persist in a viable condition in the soil for many decades. This seed may germinate profusely after a disturbance such as cultivation or fire. Non-local wattles may not appear to be behaving invasively until such an event, when their population will suddenly explode. Dispersal: Generally grows close to the parent tree, although birds may occasionally spread the seed further. Pods open explosively in hot weather, throwing the seed some distance.
