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. -

NHESP is responsible for the conservation and protection of hundreds of species that are not hunted, fished, trapped, or commercially harvested in the state. The Program's highest priority is protecting the 176 species of vertebrate and invertebrate animals and 259 species of native plants that are officially listed as Endangered, Threatened or of Special Concern in Massachusetts. Endangered species conservation in Massachusetts depends on you! A major source of funding for the protection of rare and endangered species comes from voluntary donations on state income tax forms.

D. Hook.) Baillon had been made in 1893, earlier than the combination made by G. C. Druce re ported in our revision of the genus Amphibromus in Australia (Jacobs and Lapinpuro 1986). Baillon's combination had been overlooked by Index Kewensis and by the Chase Index (Chase and Niles 1962). The full citation is: Amphibromus nervosus (J. D. Hook.)

(see Jacobs and Lapinpuro 1986 for further comment). Amphibromus nervosus (1. D. Hook.) G. C. Druce then becomes a superfluous combina tion and is added to the synonymy.

The calcinogenic principle of the plant is the active vitamin D steroid hormone 1,25-Dihydroxyvitamin D3, the major physiological regulator of calcium homeostasis in higher animals. From comparison with synthetic vitamin D metabolites in different bioassays, it is concluded that T. flavescens contains the 25-glucoside of l,25(OH)2D3. This compound, or rather the l,25(OH)2D3 liberated by ruminal fluid, is the calcinogenic factor of the grass. Introduction iological range [9].

Pearsall AUGUST 2006 Dedicated to the memory of my grandmother Joanne Marie Higgins 1940-2005 ACKNOWLEDGEMENTS There are a great number of people who have helped in this process in passing or in long, detailed conversations, and everything in between. First and foremost, many thanks to my advisor, Debby Pearsall, for creative and inspired guidance, and for taking the time to talk over everything from the smallest detail to the biggest challenges. Debby introduced me to the world of phytoliths, and then to the wonders of starch grains, and encouraged me to find and pursue the issues that drive me. My committee has been very helpful and patient, and made my oral exams and defense far more enjoyable then expected—Dr. Christine Hastorf, Dr. Bob Benfer, and Dr. Randy Miles. Dr. Benfer was crucial in helping me sort through the statistical applications. I also benefited tremendously from conversations with and advice from my cohorts in the MU Paleoethnobotany lab, or as we are better known, the “Pearsall Youth”— Neil Duncan, Shawn Collins, Meghann O’Brien, Tom Hart, and Nicole Little. Dr. Karol Chandler-Ezell gave me great advice on calcium oxalate and chemical processing. Dr. Todd VanPool graciously provided much needed advice on the statistical applications. -

Danthonia popinensis is a recently discovered, nationally endangered tussock grass, originally known from only one roadside population at Kempton, Tasmania. Six populations have been recorded, all from flat land with mildly acid non-rocky soils, and all in small toadside or paddock remnants, badly invaded by exotic plants. However, one site has recently been destroyed through roadworks. The species germinates best at temperatures of 10°e, indicating a winter germination strategy. Autumn burning at Kempton resulted in an increased cover of D. popinensis two years after the burn, but also resulted in an increased cover of competitive exotics. The future of the species needs to be secured by ex situ plantings, as almost all of its original habitat has been converted to crops or improved pasture. Key Words: Danthonia popinensis, wallaby grass, tussock grass, endangered species, Tasmania. INTRODUCTION common fire management regime (e.g. -

We investigated plant species diversity and composition in a Pinus radiata landscape in south-central Chile, a biodiversity hotspot, by sampling understory vegetation in different plantation age classes, along forest roads and in natural forest remnants in order to find effective conservation measures for native biodiversity. Plantations, including different age classes and roadsides, maintained high native species richness at the landscape scale but supported a completely different community composition than natural forests. Thus, natural forest remnants must be conserved as plantations cannot replace them. Certain natural forest species occurred frequently in mature plantations and can represent starting points for retaining natural elements in plantations. Generalist native and alien species benefited from plantation management, mainly in young plantations and along roadsides. Stand maturation and a closed canopy, though, reduced alien species occurrences within plantations. Along roads, shade-tolerant aliens should be monitored and removed as they can potentially invade natural forests. -
