Taxonomical Notes on the Genus Piptatherum P. Beauv
TAXONOMICAL NOTES ON THE GENUS PIPTATHERUM P. BEAUV. (POACEAE) IN IRAN ee & M. Assadi׳B. Hamzeh Received 2015. 02. 20; accepted for publication 2015. 05. 12 ee, B. & Assadi, M. 2015. 06. 30: Taxonomical notes on the genus Piptatherum P. Beauv. (Poaceae) in׳Hamzeh Iran. –Iran. J. Bot. 21 (1): 01-09. Tehran. Piptatherum denaense is described as a new species from south west of Iran, Dena Mountain. It is close to P. laterale but differs from it by having glabrous lemma in lower half and toward the apex, narrower vegetative shoots and unbearded anthers. Piptatherum holciforme subsp. holciforme var. glabrum is not accepted as a distinct variety. Piptatherum sphacelatum formerly known as a synonym of P. molinioides is established as a separate species due to having distinct morphological characters as well as molecular differences based on literature. Thus, the number of taxa in the genus Piptatherum changes to 9 species, 2 subspecies and 4 varieties in Iran. An identification key to Piptatherum taxa occuring in Iran is provided. The distribution map of P. denaense with P. laterale subsp. laterale and the illustration of the new species are included. ee (correspondence <[email protected]>) & Mostafa Assadi, Research Institute of Forests and׳Behnam Hamzeh Rangelands, P.

Floristic Quality Assessment Report
FLORISTIC QUALITY ASSESSMENT IN INDIANA: THE CONCEPT, USE, AND DEVELOPMENT OF COEFFICIENTS OF CONSERVATISM Tulip poplar (Liriodendron tulipifera) the State tree of Indiana June 2004 Final Report for ARN A305-4-53 EPA Wetland Program Development Grant CD975586-01 Prepared by: Paul E. Rothrock, Ph.D. Taylor University Upland, IN 46989-1001 Introduction Since the early nineteenth century the Indiana landscape has undergone a massive transformation (Jackson 1997). In the pre-settlement period, Indiana was an almost unbroken blanket of forests, prairies, and wetlands. Much of the land was cleared, plowed, or drained for lumber, the raising of crops, and a range of urban and industrial activities. Indiana’s native biota is now restricted to relatively small and often isolated tracts across the State. This fragmentation and reduction of the State’s biological diversity has challenged Hoosiers to look carefully at how to monitor further changes within our remnant natural communities and how to effectively conserve and even restore many of these valuable places within our State. To meet this monitoring, conservation, and restoration challenge, one needs to develop a variety of appropriate analytical tools. Ideally these techniques should be simple to learn and apply, give consistent results between different observers, and be repeatable. Floristic Assessment, which includes metrics such as the Floristic Quality Index (FQI) and Mean C values, has gained wide acceptance among environmental scientists and decision-makers, land stewards, and restoration ecologists in Indiana’s neighboring states and regions: Illinois (Taft et al. 1997), Michigan (Herman et al. 1996), Missouri (Ladd 1996), and Wisconsin (Bernthal 2003) as well as northern Ohio (Andreas 1993) and southern Ontario (Oldham et al. -
Phylogenetics of Piptatherum Sl (Poaceae: Stipeae)

Soreng,2 Oksana Futorna3 & Alfonso Susanna1 1 Laboratory of Molecular Systematics, Botanic Institute of Barcelona (CSIC−ICUB), Passeig del Migdia s.n., 08038 Barcelona, Spain 2 Department of Botany, National Museum of Natural History, Smithsonian Institution, Washington, D.C. 20013, U.S.A. 3 M.G. Kholodny Institute of Botany, National Academy of Sciences of Ukraine, 01601 Kiev, Ukraine Author for correspondence: Paul M. Peterson, [email protected] Abstract Historically, there has been taxonomic confusion among agrostologists regarding the short-spikeleted Stipeae. We refer to these as the Oryzopsis/Piptatherum complex which consists of short-spikeleted species with coriaceous to cartilaginous and often caducous-awned lemmas, and florets with a blunt callus. We conducted a phylogenetic analysis of 53 species that have been associated with this complex using four plastid regions (ndhF, rpl32-trnL, rps16-trnK, rps16 intron) in combination with lemma micromorphology to infer evolutionary relationships. Piptatherum as currently circumscribed is polyphyletic and is found in five strongly supported clades in our maximum likelihood tree. Based on our phylogenetic and morphological evidence we recognize a Eurasian Piptatherum s.str., propose a new genus, Piptatheropsis, to include five North American species, and resurrect the genus Patis to include three species, two from Eurasia and one from North America. We provide morphological descriptions of Patis, Piptatherum, and Piptatheropsis, and provide keys to the genera and species of the Oryzopsis/Piptatherum complex. -

Vascular Plant Species of the Comanche National Grassland in United States Department Southeastern Colorado of Agriculture
Vascular Plant Species of the Comanche National Grassland in United States Department Southeastern Colorado of Agriculture Forest Service Donald L. Hazlett Rocky Mountain Research Station General Technical Report RMRS-GTR-130 June 2004 Hazlett, Donald L. 2004. Vascular plant species of the Comanche National Grassland in southeast- ern Colorado. Gen. Tech. Rep. RMRS-GTR-130. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 36 p. Abstract This checklist has 785 species and 801 taxa (for taxa, the varieties and subspecies are included in the count) in 90 plant families. The most common plant families are the grasses (Poaceae) and the sunflower family (Asteraceae). Of this total, 513 taxa are definitely known to occur on the Comanche National Grassland. The remaining 288 taxa occur in nearby areas of southeastern Colorado and may be discovered on the Comanche National Grassland. The Author Dr. Donald L. Hazlett has worked as an ecologist, botanist, ethnobotanist, and teacher in Latin America and in Colorado. He has specialized in the flora of the eastern plains since 1985. His many years in Latin America prompted him to include Spanish common names in this report, names that are seldom reported in floristic pub- lications. He is also compiling plant folklore stories for Great Plains plants. Since Don is a native of Otero county, this project was of special interest.

Plastid DNA variation within Austrostipa was low and only few lineages were resolved. -

Keywords Stipeae, Stipa, Piptochaetium, nomenclature Introduction In February 2010, Gandhi, in responding to an inquiry from Dr. Travis Columbus, noticed that the name Piptochaetium setosum (Trin.) Arechav. was superfluous and illegitimate at the time of publication because its basionym, Urachne setosa Trin., was it- self superfluous and illegitimate at the time of publication, Trinius having included in it two older and validly published names, Stipa panicoides Lam. -
Piptatherum Canadense (Poiret) Dorn Canada Ricegrass
New England Plant Conservation Program Piptatherum canadense (Poiret) Dorn Canada Ricegrass Conservation and Research Plan for New England Prepared by: Marc Lapin, Ph.D. Ecologist Ecosystem Science and Conservation 239 Cider Mill Road Cornwall, VT 05753 For: New England Wild Flower Society 180 Hemenway Road Framingham, Massachusetts 01701 USA 508/877-7630 e-mail: [email protected] • website: www.newfs.org Approved, Regional Advisory Council, May 2004 SUMMARY Piptatherum canadense (Poiret) Dorn (Poaceae) is a perennial grass that is broadly distributed from the Canadian Maritime Provinces to the Alberta-British Columbia border and extends southward into northern New England and the northern Great Lakes States. Although it is widely distributed in forested regions of northern North America, the species is apparently nowhere common, and it is ranked as rare in 12 of the 15 states or provinces in which it is known to occur. It is considered to have been extirpated from Prince Edward Island. In New England, P. canadense occurs only in Maine and New Hampshire, with most of the extant and historic occurrences in Washington and Hancock counties of Maine. It is ranked S2 (rare) and listed as a Special Concern species in Maine, which hosts eight extant populations. In New Hampshire, where there are two extant populations, the species is listed as Endangered and ranked S1 (very rare). Three extant populations are known from northern New York, where P. canadense is ranked S1S2 and is listed as Threatened. This grass appears to be most common in central Quebec and central Ontario, but there are only 23 and 18 documented extant occurrences, respectively. -
