Muelleria Vol 32, 2014
Muelleria 33: 85–95 Published online in advance of the print edition, 21 April 2015. Nomenclature, variation and hybridisation in Rough Blown-grass (Poaceae: Lachnagrostis) Austin J. Brown National Herbarium of Victoria, Royal Botanic Gardens Melbourne, Birdwood Avenue, South Yarra 3141, Victoria, Australia; tel: +61 3 9252 2300; e-mail: [email protected] Introduction Abstract Variation in Rough Blown-grass (also known as Ruddy, Even or Meagre The name Lachnagrostis scabra ‘(P. Blown-grass) has been previously examined by Brown (2006) with the Beauv.) Nees ex Steud.’ for Rough Blown-grass is found to be a result that Lachnagrostis aequata (Nees) S.W.L.Jacobs (syn. Agrostis misapplication of Lachnagrostis scabra aequata Nees) and L. scabra ‘(P.Beauv.) Nees ex Steud.’ (syn. Agrostis scabra Nees ex Steud. (currently known R.Br. non Willd.) were considered to be the same taxon. In addition, it was as Agrostis pilosula Trin.): an Asiatic found that the name L. aequata had been misapplied to a Tasmanian taxon not found in Australia. The montane taxon, which was subsequently described as L. morrisii A.J.Br. correct name for Rough Blown-grass is Lachnagrostis rudis (Roem. & Schult.) Recent doubt expressed in Tropicos (2014) and APC (2014) concerning Trin. A dwarf form of the species the status of Vilfa scabra P.Beauv. as a new name or a new combination from Flinders Island is described as for A. scabra Willd. or A. scabra R.Br. respectively, has initiated a closer L. rudis subsp. nana A.J.Br., based examination of the name L. scabra Nees ex Steud. -

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. -

Long-Term Changes in Biological Soil Crust Cover and Composition Eva Dettweiler-Robinson1*, Jeanne M Ponzetti2 and Jonathan D Bakker3
Dettweiler-Robinson et al. Ecological Processes 2013, 2:5 http://www.ecologicalprocesses.com/content/2/1/5 RESEARCH Open Access Long-term changes in biological soil crust cover and composition Eva Dettweiler-Robinson1*, Jeanne M Ponzetti2 and Jonathan D Bakker3 Abstract Introduction: Communities change over time due to disturbances, variations in climate, and species invasions. Biological soil crust communities are important because they contribute to erosion control and nutrient cycling. Crust types may respond differently to changes in environmental conditions: single-celled organisms and bryophytes quickly recover after a disturbance, while lichens are slow growing and dominate favorable sites. Community change in crusts has seldom been assessed using repeated measures. For this study, we hypothesized that changes in crust composition were related to disturbance, topographic position, and invasive vegetation. Methods: We monitored permanent plots in the Columbia Basin in 1999 and 2010 and compared changes in crust composition, cover, richness, and turnover with predictor variables of herbivore exclosure, elevation, heat load index, time since fire, presence of an invasive grass, and change in cover of the invasive grass. Results: Bryophytes were cosmopolitan with high cover. Dominant lichens did not change dramatically. Indicator taxa differed by monitoring year. Bryophyte and total crust cover declined, and there was lower turnover outside of herbivore exclosures. Lichen cover did not change significantly. Plots that burned recently had high turnover. Increase in taxon richness was correlated with presence of an invasive grass in 1999. Change in cover of the invasive grass was positively related to proportional loss and negatively related to gain. Conclusions: Composition and turnover metrics differed significantly over 11 years, though cover was more stable between years. -
Colonial and Highland Bentgrass (Agrostis Sp.) Tom Cook Assoc. Professor Hort. Oregon State University Introduction: in Areas We
Colonial and Highland bentgrass (Agrostis sp.) Tom Cook Assoc. Professor Hort. Oregon State University Introduction: In areas west of the Cascade Mountains from Vancouver, BC as far south as Grants Pass, OR and along the coast clear down to the San Francisco, CA area, bentgrasses are arguably the most important grasses used for turf. Ironically, they have rarely been knowingly planted since approximately the mid-1970’s. Today, bentgrasses most often come into lawns as contaminants in soil and in some cases in seed or sod mixtures. Despised by the seed trade and many people involved in commercial landscape maintenance, bentgrasses are uniquely suited to the mild climate and consistently out compete even the most elite cultivars of perennial ryegrass, fine fescues, Tall fescue, and Kentucky bluegrass. Like it or not bentgrass is here to stay! Taxonomy and history: The taxonomy of bentgrasses is complicated and confusing because it involves numerous species and interspecies hybrids that are very similar in appearance. To make matters worse, early plantings dating back to frontier days were composed of mixtures of species brought to America from Europe. Today in any stand of bentgrass you are likely to find three or four different species. In A.S. Hitchcocks “Manual of the Grasses of the United States” (1971) first published in 1935, he describes Colonial bentgrass as Agrostis tenuis Sibth. In his own words, “This species appears not to be native in America; it has been referred to A. capillaris L., a distinct species in Europe.” The wording in this description is odd and it is not clear if he means that Agrostis tenuis is in fact Agrostis capillaris or is a distinct species that is related to Agrostis capillaris. -

3 Invasive Species in the Sonoran Desert Region
3 Invasive Species in the Sonoran Desert Region 11 INVASIVE SPECIES IN THE SONORAN DESERT REGION Invasive species are altering the ecosystems of the Sonoran Desert Region. Native plants have been displaced resulting in radically different habitats and food for wildlife. Species like red brome and buffelgrass have become dense enough in many areas to carry fire in the late spring and early summer. Sonoran Desert plants such as saguaros, palo verdes and many others are not fire- adapted and do not survive these fires. The number of non-native species tends to be lowest in natural areas of the Sonoran Desert and highest in the most disturbed and degraded habitats. However, species that are unusually aggressive and well adapted do invade natural areas. In the mid 1900’s, there were approximately 146 non-native plant species (5.7% of the total flora) in the Sonoran Desert. Now non-natives comprise nearly 10% of the Sonoran Desert flora overall. In highly disturbed areas, the majority of species are frequently non-native invasives. These numbers continue to increase. It is crucial that we monitor, control, and eradicate invasive species that are already here. We must also consider the various vectors of dispersal for invasive species that have not yet arrived in Arizona, but are likely to be here in the near future. Early detection and reporting is vital to prevent the spread of existing invasives and keep other invasives from arriving and establishing. This is the premise of the INVADERS of the Sonoran Desert Region program at the Arizona-Sonora Desert Museum. -
