"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -

Grass Genera in Townsville
Grass Genera in Townsville Nanette B. Hooker Photographs by Chris Gardiner SCHOOL OF MARINE and TROPICAL BIOLOGY JAMES COOK UNIVERSITY TOWNSVILLE QUEENSLAND James Cook University 2012 GRASSES OF THE TOWNSVILLE AREA Welcome to the grasses of the Townsville area. The genera covered in this treatment are those found in the lowland areas around Townsville as far north as Bluewater, south to Alligator Creek and west to the base of Hervey’s Range. Most of these genera will also be found in neighbouring areas although some genera not included may occur in specific habitats. The aim of this book is to provide a description of the grass genera as well as a list of species. The grasses belong to a very widespread and large family called the Poaceae. The original family name Gramineae is used in some publications, in Australia the preferred family name is Poaceae. It is one of the largest flowering plant families of the world, comprising more than 700 genera, and more than 10,000 species. In Australia there are over 1300 species including non-native grasses. In the Townsville area there are more than 220 grass species. The grasses have highly modified flowers arranged in a variety of ways. Because they are highly modified and specialized, there are also many new terms used to describe the various features. Hence there is a lot of terminology that chiefly applies to grasses, but some terms are used also in the sedge family. The basic unit of the grass inflorescence (The flowering part) is the spikelet. The spikelet consists of 1-2 basal glumes (bracts at the base) that subtend 1-many florets or flowers. -

Phylogenetic Reconstruction Prompts Taxonomic Changes in Sauropus, Synostemon and Breynia (Phyllanthaceae Tribe Phyllantheae)
Blumea 59, 2014: 77–94 www.ingentaconnect.com/content/nhn/blumea RESEARCH ARTICLE http://dx.doi.org/10.3767/000651914X684484 Phylogenetic reconstruction prompts taxonomic changes in Sauropus, Synostemon and Breynia (Phyllanthaceae tribe Phyllantheae) P.C. van Welzen1,2, K. Pruesapan3, I.R.H. Telford4, H.-J. Esser 5, J.J. Bruhl4 Key words Abstract Previous molecular phylogenetic studies indicated expansion of Breynia with inclusion of Sauropus s.str. (excluding Synostemon). The present study adds qualitative and quantitative morphological characters to molecular Breynia data to find more resolution and/or higher support for the subgroups within Breynia s.lat. However, the results show molecular phylogeny that combined molecular and morphological characters provide limited synergy. Morphology confirms and makes the morphology infrageneric groups recognisable within Breynia s.lat. The status of the Sauropus androgynus complex is discussed. Phyllanthaceae Nomenclatural changes of Sauropus species to Breynia are formalised. The genus Synostemon is reinstated.

Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations. -
BIODIVERSITY CONSERVATION on the TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and Plants
BIODIVERSITY CONSERVATION ON THE TIWI ISLANDS, NORTHERN TERRITORY: Part 1. Environments and plants Report prepared by John Woinarski, Kym Brennan, Ian Cowie, Raelee Kerrigan and Craig Hempel. Darwin, August 2003 Cover photo: Tall forests dominated by Darwin stringybark Eucalyptus tetrodonta, Darwin woollybutt E. miniata and Melville Island Bloodwood Corymbia nesophila are the principal landscape element across the Tiwi islands (photo: Craig Hempel). i SUMMARY The Tiwi Islands comprise two of Australia’s largest offshore islands - Bathurst (with an area of 1693 km 2) and Melville (5788 km 2) Islands. These are Aboriginal lands lying about 20 km to the north of Darwin, Northern Territory. The islands are of generally low relief with relatively simple geological patterning. They have the highest rainfall in the Northern Territory (to about 2000 mm annual average rainfall in the far north-west of Melville and north of Bathurst). The human population of about 2000 people lives mainly in the three towns of Nguiu, Milakapati and Pirlangimpi. Tall forests dominated by Eucalyptus miniata, E. tetrodonta, and Corymbia nesophila cover about 75% of the island area. These include the best developed eucalypt forests in the Northern Territory. The Tiwi Islands also include nearly 1300 rainforest patches, with floristic composition in many of these patches distinct from that of the Northern Territory mainland. Although the total extent of rainforest on the Tiwi Islands is small (around 160 km 2 ), at an NT level this makes up an unusually high proportion of the landscape and comprises between 6 and 15% of the total NT rainforest extent. The Tiwi Islands also include nearly 200 km 2 of “treeless plains”, a vegetation type largely restricted to these islands. -

Reproductive Morphology of Sargentodoxa Cuneata (Lardizabalaceae) and Its Systematic Implications
Reproductive morphology of Sargentodoxa cuneata (Lardizabalaceae) and its systematic implications. By: Hua-Feng Wang, Bruce K. Kirchoff and Zhi-Xin Zhu Wang, H.-F., Kirchoff, B. K., Qin, H.-N., Zhu, Z.-X. 2009. Reproductive morphology of Sargentodoxa cuneata (Lardizabalaceae) and its systematic implications. Plant Systematics and Evolution 280: 207–217. Made available courtesy of Springer-Verlag. The original publication is available at http://link.springer.com/article/10.1007%2Fs00606-009-0179-3. ***Reprinted with permission. No further reproduction is authorized without written permission from Springer-Verlag. This version of the document is not the version of record. Figures and/or pictures may be missing from this format of the document. *** Abstract: The reproductive morphology of Sargentodoxa cuneata (Oliv) Rehd. et Wils. is investigated through field, herbarium, and laboratory observations. Sargentodoxa may be either dioecious or monoecious. The functionally unisexual flowers are morphologically bisexual, at least developmentally. The anther is tetrasporangiate, and its wall, of which the development follows the basic type, is composed of an epidermis, endothecium, two middle layers, and a tapetum. The tapetum is of the glandular type. Microspore cytokinesis is simultaneous, and the microspore tetrads are tetrahedral. Pollen grains are two-celled when shed. The mature ovule is crassinucellate and bitegmic, and the micropyle is formed only by the inner integument. Megasporocytes undergo meiosis resulting in the formation of four megaspores in a linear tetrad. The functional megaspore develops into an eight-nucleate embryo sac after three rounds of mitosis. The mature embryo sac consists of an egg apparatus (an egg and two synergids), a central cell, and three antipodal cells.
