Grasses are frequently distributed. Grasses are adapted to all habitats. The present study describes the Key Words: floristic diversity of Poaceae and Cyperaceae family in Bolpur- Grasses, herbarium, survey Santiniketan area of West Bengal, India. Each plant species was collected, dried and mounted on the herbarium sheet and was identified. A total of sixteen grass species were found in Bolpur- Santiniketan area of West Bengal INTRODUCTION (compositae), Fabaceae (Leguminosae) and Orchidaceae contain more species than poaceae. The role of systematic in studies of Grasses are among the most adaptable life forms. biodiversity is essential to a variety of studies, The name Poaceae was given by John Hendley including species conservation, extinction, Barnhart in 1895, based on the tribe poeae biodiversity hotspots, bio-prospecting and described in 1814 by Robert Brown, and the type ecosystem function (Alroy 2002; Smith and genus poa described in 1753 by Carl Linnaeus.

A factorial arrangement with four fertilizer types (control, urea, compost and urea + compost), and three harvesting ages (90, 120 and 150) with three replications were used. Data on morphological characteristics of the grass were recorded. Based on the data collected, harvesting age was significantly affected the agronomic parameters of the grass. Plant height (PH), number of tillers per plant (NTPP), number of leaves per plant (NLPP), number of leaves per tiller (NLPT), dry matter yield (DMY), leaf length (LL) and leaf area (LA) were increased with increasing harvesting age, while leaf to stem ratio (LSR) showed a decreasing trend.

  • 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.

Inflorescence of single or subdigitate racemes, terminal or also axillary and sometimes supported by spathes; racemes usually with 1 or more basal homogamous spikelet pairs, spikelets often imbricate; rachis internodes and pedicels slender, solid, bearded, truncate or oblique at apex. Sessile spikelet dorsally compressed; callus short, obtuse; lower glume papery to cartilaginous, broadly convex to slightly concave, sometimes pitted, rounded on flanks, becoming 2-keeled upward, apex obtuse; upper glume boat-shaped, dorsally keeled, awnless; lower floret reduced to an empty hyaline lemma; upper lemma stipitiform, entire, awned from apex; awn geniculate, glabrous or puberulous. Stamens (2–) 3. Pedicelled spikelet similar to the sessile, male or barren, awnless. About 20 species: Africa through India to SE Asia and Australia; three species in China. Dichanthium is closely related to Bothriochloa, but can be distinguished by its pedicels and rachis internodes being solid and lacking a median, purple line. The species present in China are not clear-cut and are also variable within themselves due to polyploidy and apomixis. All three species provide good grazing and now occur widely in tropical regions as introductions or escapes. 1a.

Vascular plants and a brief history of the Kiowa and Rita Blanca National Grasslands. Gen. Tech. Rep. RMRS- GTR-233. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 44 p. Abstract Administered by the USDA Forest Service, the Kiowa and Rita Blanca National Grasslands occupy 230,000 acres of public land extending from northeastern New Mexico into the panhandles of Oklahoma and Texas. A mosaic of topographic features including canyons, plateaus, rolling grasslands and outcrops supports a diverse flora. Eight hundred twenty six (826) species of vascular plant species representing 81 plant families are known to occur on or near these public lands. This report includes a history of the area; ethnobotanical information; an introductory overview of the area including its climate, geology, vegetation, habitats, fauna, and ecological history; and a plant survey and information about the rare, poisonous, and exotic species from the area. A vascular plant checklist of 816 vascular plant taxa in the appendix includes scientific and common names, habitat types, and general distribution data for each species. This list is based on extensive plant collections and available herbarium collections. Authors Donald L.

  • Identification of Invasive Alien Species Using DNA Barcodes
    Identification of Invasive Alien Species using DNA barcodes Royal Belgian Institute of Natural Sciences Royal Museum for Central Africa Rue Vautier 29, Leuvensesteenweg 13, 1000 Brussels , Belgium 3080 Tervuren, Belgium +32 (0)2 627 41 23 +32 (0)2 769 58 54 General introduction to this factsheet The Barcoding Facility for Organisms and Tissues of Policy Concern (BopCo) aims at developing an expertise forum to facilitate the identification of biological samples of policy concern in Belgium and Europe. The project represents part of the Belgian federal contribution to the European Research Infrastructure Consortium LifeWatch. Non-native species which are being introduced into Europe, whether by accident or deliberately, can be of policy concern since some of them can reproduce and disperse rapidly in a new territory, establish viable populations and even outcompete native species. As a consequence of their presence, natural and managed ecosystems can be disrupted, crops and livestock affected, and vector-borne diseases or parasites might be introduced, impacting human health and socio-economic activities. Non-native species causing such adverse effects are called Invasive Alien Species (IAS). In order to protect native biodiversity and ecosystems, and to mitigate the potential impact on human health and socio-economic activities, the issue of IAS is tackled in Europe by EU Regulation 1143/2014 of the European Parliament and Council. The IAS Regulation provides for a set of measures to be taken across all member states. The list of Invasive Alien Species of Union Concern is regularly updated. In order to implement the proposed actions, however, methods for accurate species identification are required when suspicious biological material is encountered.
