  • Australian Orchidaceae: Genera and Species (12/1/2004)
    AUSTRALIAN ORCHID NAME INDEX (21/1/2008) by Mark A. Clements Centre for Plant Biodiversity Research/Australian National Herbarium GPO Box 1600 Canberra ACT 2601 Australia Corresponding author: [email protected] INTRODUCTION The Australian Orchid Name Index (AONI) provides the currently accepted scientific names, together with their synonyms, of all Australian orchids including those in external territories. The appropriate scientific name for each orchid taxon is based on data published in the scientific or historical literature, and/or from study of the relevant type specimens or illustrations and study of taxa as herbarium specimens, in the field or in the living state. Structure of the index: Genera and species are listed alphabetically. Accepted names for taxa are in bold, followed by the author(s), place and date of publication, details of the type(s), including where it is held and assessment of its status. The institution(s) where type specimen(s) are housed are recorded using the international codes for Herbaria (Appendix 1) as listed in Holmgren et al’s Index Herbariorum (1981) continuously updated, see [http://sciweb.nybg.org/science2/IndexHerbariorum.asp]. Citation of authors follows Brummit & Powell (1992) Authors of Plant Names; for book abbreviations, the standard is Taxonomic Literature, 2nd edn. (Stafleu & Cowan 1976-88; supplements, 1992-2000); and periodicals are abbreviated according to B-P- H/S (Bridson, 1992) [http://www.ipni.org/index.html]. Synonyms are provided with relevant information on place of publication and details of the type(s). They are indented and listed in chronological order under the accepted taxon name. Synonyms are also cross-referenced under genus.

    Journal of the Royal Society of Western Australia, 81:107-117, 1998 Flora and Vegetation of the Eastern Goldfields Ranges: Part 2. Bremer Range N Gibson & M N Lyons Science and Information Division, Department of Conservation and Land Management, Wildlife Research Centre, PO Box 51 Wanneroo WA 6065 email: [email protected]; [email protected] Manuscript received March 1997; accepted November 1997 Abstract A study of the flora and plant communities of the Bremer Range greenstone belt in the spring of 1994 recorded 267 taxa. Only eight weed species were recorded but this number is likely to increase if further work is carried out in a better season. The flora list included one species gazetted as rare and new populations of five rare or poorly known taxa. Three species appear to be endemic to the Bremer Range greenstone belt, one of which was collected for the first time. Six community types were defined from 64 sites spread across the range. The distribution of these community types appears to be primarily controlled by edaphic factors including soil water holding capacity. The floristic classification is in broad agreement with previous work but shows finer-scale patterning. None of the floristic communities or the endemic taxa are presently reserved. There has been significant impact on the vegetation of this range by mining and mineral exploration. Introduction time (possibly Cretaceous) of higher rainfall. Widespread laterization of the granites and greenstones is believed to The geology of ranges of the Goldfields region of have occurred during the Tertiary i.e. the last 65 My Western Australia has been subject to extensive and (Newbey 1988).

Jo H. Willems Plant Ecology Group, Utrecht University, PO Box 800.84, NL 3508 Utrecht, The Netherlands. "Our knowledge about the lives ofindividual plants and oftheir persistence in plant communities is very incomplete, however, especially when perennial herbs are concerned" - C. 0. Tamm, 1948. Terrestrial orchids represent a wide diversity ofspecies that are characterised by an equally diverse range of life history attributes. Threatened and endangered species of terrestrial orchids have been identifed on all continents where they occur and conservation plans have been developed for some species. Even though there is a considerable amount of information on the ecology of terrestrial orchids, few species have been studied in detail and most management plans focus on habitat conservation. In this paper, we consider the diversity of terrestrial orchids and summarise information on threatened and endangered species from a global perspective. We also describe approaches to the conservation and restoration ofterrestrial orchids and develop the argument that much information is needed ifwe are to successfully conserve this diverse group ofplant species. 1. Introduction Terrestrial orchids represent a wide variety of life history types, from autotrophic evergreen to completely myco-heterotrophic species that obtain most oftheir resources from a mycobiont. Life history characteristics ofterrestrial orchids are generally well known (e.g.
