After nearly ten years the meeting has grown into a biennial three-day symposium rotating among different locations throughout the Eastern United States. This is quite an accomplishment for an event that has no sponsoring organization. The Eastern Native Grass Symposium is sustained by the expanding interest in the subject and the devotion of a variety of people, from agency technical specialists and private consultants, to growers of seed and nursery stock, to equipment and pesticide dealers. Presentations at the first symposium focused on native grass establishment and management for forage production and grassland restoration. This fifth symposium is made up of over 90 oral and poster presentations. Topics include biofuels and carbon sequestration, biomass, cultivar and ecotype development, establishment and weed control, forages and grazing, genetics, invasive species, reclamation and restoration, roadside management, seed harvest and processing, and wildlife management. Beginning with the second symposium in Baltimore, Maryland in 1999, the event has included field trips and on-site workshops. This fifth symposium provides six choices for full-day field trips and three workshop subjects. The second symposium was also the first time proceedings were published. This fifth symposium is the first time the proceedings are published in advance of the symposium. Since the symposium was last in the Mid-Atlantic region, both the knowledge and experience bases of native grass establishment in the Eastern United States have increased significantly. The best management for each of the many uses of native grasses is now a significant concern. There is a noticeable shift in the subject matter of presentations from establishment to management. This quote from the proceedings of the second symposium is as applicable now as is it was seven years ago: “Native grass use is expanding as rapidly as the seed and plant supplies of eastern sources will allow. The recent demand for materials is being driven by both a desire to utilize native plants to meet resource conservation objectives, and additional discovery of valuable functions which native grasses bring to discreet habitats and the environment in general. Native grasses bring a host of valuable traits to the conservation effort. Relatively unknown, under-appreciated, under-researched, and therefore under-used, native grasses will [continue to] play a powerful role in environmental improvement as use technology is developed and institutionalized.” The Planning Committee iii 4 PROCEEDINGS OF THE FIFTH EASTERN NATIVE GRASS SYMPOSIUM_________________ THE PLANNING COMMITTEE Barry Isaacs, Co-Chair, USDA, Natural Resources Conservation Service, PA Chris Miller, Co-Chair, USDA, Natural Resources Conservation Service, NJ Martin van der Grinten, Co-Chair, USDA, Natural Resources Conservation Service, NY Calvin Ernst, Exhibits Chair, Ernst Conservation Seeds, PA Mike Pruss, Field Trips Chair, Pennsylvania Game Commission Paul Salon, Program Chair, USDA, Natural Resources Conservation Service, NY Kathleen Banski, Pennsylvania Association of Conservation Districts Tom Barnes, University of Kentucky Tim Dunne, USDA, Natural Resources Conservation Service, NJ Bob Escheman, USDA, Natural Resources Conservation Service, Wash., DC Dave Lorenz, Truax Company, Inc., PA R.

Dickerson Finger Lakes Conservation Services Marcellus, New York These Proceedings of the Fifth Eastern Native Grass Symposium are dedicated to John A. Dickerson, formerly Plant Materials Specialist, USDA, Natural Resources Conservation Service (retired). John has worked to advance the knowledge of native grasses in the Eastern United States for decades. During his career with USDA, he supported the Big Flats Plant Materials Center, Big Flats, New York in collecting, evaluating, and releasing native grasses, and in assisting commercial growers with their production. John tested and developed technologies to re-vegetate sand and gravel pits in New York and throughout New England with native grasses. He continues to exchange ideas and technology on native grass establishment and management with people throughout the North American continent. John has played a key role in all five of the Eastern Native Grass Symposiums, including Co- Chairing the second symposium. And he continues to demonstrate his leadership role by accepting responsibility to solicit a host for the Sixth Symposium to be held in 2008. v 6 PROCEEDINGS OF THE FIFTH EASTERN NATIVE GRASS SYMPOSIUM_________________ TABLE OF CONTENTS Author(s) Title__________________________________________________________________Page Biofuels Adler, P.

    "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.

CONTRIBUTIONS FROM THE United States National Herbarium Volume XII, Part 3 TXE&3 OF AMERICAN GRASSES . / A STUDY OF THE AMERICAN SPECIES OF GRASSES DESCRIBED BY LINNAEUS, GRONOVIUS, SLOANE, SWARTZ, AND MICHAUX By A. S. HITCHCOCK z rit erV ^-C?^ 1 " WASHINGTON GOVERNMENT PRINTING OFFICE 1908 BULLETIN OF THE UNITED STATES NATIONAL MUSEUM Issued June 18, 1908 ii PREFACE The accompanying paper, by Prof. A. S. Hitchcock, Systematic Agrostologist of the United States Department of Agriculture, u entitled Types of American grasses: a study of the American species of grasses described by Linnaeus, Gronovius, Sloane, Swartz, and Michaux," is an important contribution to our knowledge of American grasses. It is regarded as of fundamental importance in the critical sys- tematic investigation of any group of plants that the identity of the species described by earlier authors be determined with certainty. Often this identification can be made only by examining the type specimen, the original description being inconclusive. Under the American code of botanical nomenclature, which has been followed by the author of this paper, "the nomenclatorial t}rpe of a species or subspecies is the specimen to which the describer originally applied the name in publication." The procedure indicated by the American code, namely, to appeal to the type specimen when the original description is insufficient to identify the species, has been much misunderstood by European botanists. It has been taken to mean, in the case of the Linnsean herbarium, for example, that a specimen in that herbarium bearing the same name as a species described by Linnaeus in his Species Plantarum must be taken as the type of that species regardless of all other considerations.

Paspalum is a rather large genus “numbering nearly 400” species (Chase, 1929). Sour paspalum (Paspalum conjugatum) stands by itself in this genus as suggested by Chase (1929) who created for it, alone, the Section Conjugata (Fig. 1). Its most unusual character is the vigorously stoloniferous habit allowing, at times, for a rapidly formed perennial ground cover. Sour paspalum has been assumed to be native where it occurs in the Americas, from Florida to Texas and southward to Peru, Bolivia, and northern Argentina, from sea level to 4,000 ft elevation. The grass was first described from a specimen collected in Surinam (Dutch Guiana). Sour paspalum has been assumed, however, to be intro- duced wherever it occurs in the Old World tropics (Fig. 2) and Pacific Islands. The early trade routes were between Australia, Singapore, and Africa. Probably both carpetgrass (Axonopus compressus) and sour paspalum, being of similar distribution and ecology, were spread at the same time to the same places.
  • Grass Genera in Townsville

    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.

By M. Forbes Boyle, Robert K. Peet, Thomas R. Wentworth, Michael P. Schafale, and Michael Lee Carolina Vegetation Survey Curriculum in Ecology, CB#3275 University of North Carolina Chapel Hill, NC 27599‐3275 Version 1. May 19, 2009 1 INTRODUCTION The riverine and associated vegetation of the Waccamaw, Lumber, and Little Pee Rivers of North and South Carolina are ecologically significant and floristically unique components of the southeastern Atlantic Coastal Plain. Stretching from northern Scotland County, NC to western Brunswick County, NC, the Lumber and northern Waccamaw Rivers influence a vast amount of landscape in the southeastern corner of NC. Not far south across the interstate border, the Lumber River meets the Little Pee Dee River, influencing a large portion of western Horry County and southern Marion County, SC before flowing into the Great Pee Dee River. The Waccamaw River, an oddity among Atlantic Coastal Plain rivers in that its significant flow direction is southwest rather that southeast, influences a significant portion of the eastern Horry and eastern Georgetown Counties, SC before draining into Winyah Bay along with the Great Pee Dee and several other SC blackwater rivers. The Waccamaw River originates from Lake Waccamaw in Columbus County, NC and flows ~225 km parallel to the ocean before abrubtly turning southeast in Georgetown County, SC and dumping into Winyah Bay.
