By EurekAlert! Giant Eucalypts sent back to the rainforest By Rachel Sullivan Abstract: Dual mycorrhizal associations of jarrah (Eucalyptus marginata) in a nurse-pot system The Eucalypt's survival secret By Danny Kingsley Plant Profile; Corymbia gummifera By Tony Popovich Eucalyptus ×trabutii By Warwick Varley SUBSCRIPTION TIME Do Australia's giant fire-dependent trees belong in the rainforest? By EurekAlert! Australia's giant eucalyptus trees are the tallest flowering plants on earth, yet their unique relationship with fire makes them a puzzle for ecologists. Now the first global assessment of these giants, published in New Phytologist, seeks to end a century of debate over the species' classification and may change the way it is managed in future. Gigantic trees are rare. Of the 100,000 global tree species only 50, less than 0.005 per cent, reach over 70 metres in height. While many of the giants live in Pacific North America, Borneo and similar habitats, 13 are eucalypts endemic to Southern and Eastern Australia. The tallest flowering plant in Australia is Eucalyptus regnans, with temperate eastern Victoria and Tasmania being home to the six tallest recorded species of the genus. -

Evolutionary Relationships in Eucalyptus Sens. Lat. – a Synopsis
Euclid - Online edition Evolutionary relationships in Eucalyptus sens. lat. – a synopsis This article complements the introductory essay about eucalypts included in the "Learn about Eucalypts" section. Its aim is to provide an up-to-date account of the outcomes of research derived from different groups during the past 5 years relating to relationships within Eucalyptus s.s. As such it includes only those publications and hypotheses relating to higher level relationships of major groupings within the eucalypts. Some of the research reported below also provides insights into biogeographic relationships of the eucalypt group – in large part these are not the focus of this article and are not discussed in detail. Introduction The first comprehensive classification of the eucalypts was published by Blakely in 1934, in which he treated more than 600 taxa, building on earlier work of Maiden and Mueller. Blakely's classification remained the critical reference for Eucalyptus taxonomists for the next 37 years when a new but informal classification was published by Pryor and Johnson (1971). In this work the authors divided the genus into seven subgenera, and although of an informal nature, presented a system of great advance on Blakely's treatment. The small genus Angophora was retained. The next 20 years saw much debate about the naturalness of Eucalyptus and whether other genera should be recognized (e.g., Johnson 1987). Based on morphological data, Hill and Johnson in 1995 proposed a split in the genus and recognition of the genus Corymbia. This new genus of c. 113 species, comprised the ghost gums and the bloodwoods, and Hill and Johnson concluded that Corymbia is the sister group to Angophora, with the synapomorphy of the distinctive cap cells on bristle glands (Ladiges 1984) being unambiguous. -
Gum Trees Talk Notes
Australian Plants Society NORTH SHORE GROUP Eucalyptus, Angophora, Corymbia FAMILY MYRTACEAE GUM TREES OF THE KU-RING-GAI WILDFLOWER GARDEN Did you know that: • The fossil evidence for the first known Gum Tree was from the Tertiary 35-40 million years ago. • Myrtaceae is a very large family of over 140 genera and 3000 species of evergreen trees and shrubs. • There are over 900 species of Gum Trees in the Family Myrtaceae in Australia. • In the KWG, the Gum Trees are represented in the 3 genera: Eucalyptus, Angophora & Corymbia. • The name Eucalyptus is derived from the Greek eu = well and kalyptos = covered. BRIEF HISTORY E. obliqua The 18th &19th centuries were periods of extensive land exploration in Australia. Enormous numbers of specimens of native flora were collected and ended up in England. The first recorded scientific collection of Australian flora was made by Joseph Banks and Daniel Solander, during Sir James Cook’s 1st voyage to Botany Bay in April 1770. From 1800-1810, George Caley collected widely in N.S.W with exceptional skill and knowledge in his observations, superb preservation of plant specimens, extensive records and fluent expression in written records. It is a great pity that his findings were not published and he didn’t receive the recognition he deserved. The identification and classification of the Australian genus Eucalyptus began in 1788 when the French botanist Charles L’Heritier de Brutelle named a specimen in the British Museum London, Eucalyptus obliqua. This specimen was collected by botanist David Nelson on Captain Cook’s ill- fated third expedition in 1777 to Adventure Bay on Tasmania’s Bruny Is. -

Two Centuries of Botanical Exploration along the Botanists Way, Northern Blue Mountains, N.S.W: a Regional Botanical History that Refl ects National Trends DOUG BENSON Honorary Research Associate, National Herbarium of New South Wales, Royal Botanic Gardens and Domain Trust, Sydney NSW 2000, AUSTRALIA. [email protected] Published on 10 April 2019 at https://openjournals.library.sydney.edu.au/index.php/LIN/index Benson, D. (2019). Two centuries of botanical exploration along the Botanists Way, northern Blue Mountains,N.S.W: a regional botanical history that refl ects national trends. Proceedings of the Linnean Society of New South Wales 141, 1-24. The Botanists Way is a promotional concept developed by the Blue Mountains Botanic Garden at Mt Tomah for interpretation displays associated with the adjacent Greater Blue Mountains World Heritage Area (GBMWHA). It is based on 19th century botanical exploration of areas between Kurrajong and Bell, northwest of Sydney, generally associated with Bells Line of Road, and focussed particularly on the botanists George Caley and Allan Cunningham and their connections with Mt Tomah. Based on a broader assessment of the area’s botanical history, the concept is here expanded to cover the route from Richmond to Lithgow (about 80 km) including both Bells Line of Road and Chifl ey Road, and extending north to the Newnes Plateau. The historical attraction of botanists and collectors to the area is explored chronologically from 1804 up to the present, and themes suitable for visitor education are recognised. Though the Botanists Way is focused on a relatively limited geographic area, the general sequence of scientifi c activities described - initial exploratory collecting; 19th century Gentlemen Naturalists (and lady illustrators); learned societies and publications; 20th century publicly-supported research institutions and the beginnings of ecology, and since the 1960s, professional conservation research and management - were also happening nationally elsewhere. -

Morphology and Vascular Anatomy of the Flower of Angophora Intermedia
© Landesmuseum für Kärnten; download www.landesmuseum.ktn.gv.at/wulfenia; www.biologiezentrum.at Wulfenia 13 (2006): 11–19 Mitteilungen des Kärntner Botanikzentrums Klagenfurt Morphology and vascular anatomy of the fl ower of Angophora intermedia DC. (Myrtaceae) with special emphasis on the innervation of the fl oral axis Sergey A. Volgin & Anastasiya Stepanova Summary: A peculiar receptacle structure in Angophora intermedia DC. (Myrtaceae) has been determined by a vascular-anatomical method. The vascular system of the fl ower of A. intermedia consists of numerous ascending bundles and girdling bundles in the hypanthium and the inferior ovary wall. In the central column of the trilocular ovary we found a dense conical plexus of vascular bundles supplying the placentae (infralocular plexus). It is connected with ascending bundles of the receptacle in the ovary base. In its central part it contains “hanged” bundles and blind bundles, so it seems to be a residual stele of a rudimentary fl oral apex. Thus, the receptacle ofA. intermedia is toroidal at the level of fl oral organs and conical above the carpel node. Keywords: Angophora intermedia, Myrtaceae, fl ower morphology, vascular system, fl oral axis, innervation, anatomy The fl oral development in different species of Myrtaceae has been studied precisely to elucidate the homology of the inferior ovary, hypanthium, operculate perianth and stamens of the polymerous androecium (PAYER 1857; MAYR 1969; BUNNIGER 1972; DRINNAN & LADIGES 1988; RONSE DECRAENE & SMETS 1991; ORLOVICH et al. 1996). Developmental and histogenetical studies have shown, that the receptacle in the fl ower of Myrtaceae is cup-like and take part to certain extent in the formation of the inferior ovary wall and the hypanthium (PAYER 1857; BUNNIGER 1972; RONSE DECRAENE & SMETS 1991). -

The Threat of the Non-Native Neotropical Rust Puccinia Psidii to Hawaiian Biodiversity and Native Ecosystems: a Case Example of the Need for Prevention
The Threat of the Non-native Neotropical Rust Puccinia psidii to Hawaiian Biodiversity and Native Ecosystems: A Case Example of the Need for Prevention Lloyd Loope, U.S. Geological Survey,Pacific Island Ecosystems Research Center, Haleaka- la Field Station, P.O. Box 369, Makawao, HI 96768; [email protected] Janice Uchida, Department of Plant and Environmental Protection Sciences, University of Hawaii at Manoa, 3190 Maile Way, Honolulu, HI 96822; [email protected] Loyal Mehrhoff, U.S. Geological Survey, Pacific Island Ecosystems Research Center, 677 Ala Moana Boulevard, Suite 615, Honolulu, HI 96813; [email protected] Introduction The threat of invasive species to natural areas presents enormous challenges, but there are opportunities for working toward solutions, often in conjunction with agricultural and forestry perspectives. There is a growing awareness of the danger to botanical biodiversity and conservation from “emerging infectious diseases” that have increased in incidence, geo- graphical distribution, or host range/pathogenicity; have newly evolved characteristics; and/or have been newly discovered (Anderson et al. 2004). There is a heightened concern for forest health due to accelerating worldwide movement of plant pathogens (e.g., with inef- fective quarantine measures) that negatively affect both biodiversity and commercial forestry (Wingfield 2003). An important related concept is that of the ability of fungi to jump to new hosts following anthropogenic introduction. Native hosts are exposed to pathogens with no coevolved recognition or defense mechanism, and microevolution toward increased viru- lence of introduced pathogens can result (Wingfield 2003; Slippers et al. 2005). The rust fungus Puccinia psidii (Basidiomycota, Uredinales: Pucciniaceae), a species first document- ed to have jumped from native guava (Psidium guajava, Myrtaceae) to introduced Eucalyp- tus spp.
