Luronium Natans
Luronium natans Status UK Biodiversity Action Plan Priority species. Nationally Scarce. Schedule 8, Wildlife & Countryside Act (1981). IUCN Threat category: Least concern (2005). Taxonomy Magnoliopsida: Alismataceae Scientific names: Luronium natans (L.) Raf. Common names: Floating Water-plantain, Dŵr-lyriad Nofiadwy Luronium natans (Alisma natans L.) is a distinct member of the Water-plantain family, and is the only representative of its genus. Biology & Distribution Luronium is under-recorded due to its generally submerged aquatic habitat, shy flowering, great phenotypic plasticity and similarity to other aquatic plants. The leaves do not tend to be caught on NB. Floating grapnels or get washed ashore and often the easiest leaves are way to find it in water is to dive or use a long hooked usually more blunt than pole. It may also be found easily when exposed in Submerged illustrated seasonal ponds. The species can grow in both isolated leaves clumps or extensive lawns on the bottom of canals, lochs, ponds, etc., in water up to 4 m depth. Figure 1. Luronium natans (from J. Sowerby & J. E.

Importance to preserve wetland and wetlands plants Glossary Bibliography Biographical Sketch Summary UNESCO – EOLSS Tropical ecosystems have a high diversity of environments, many of them with high seasonal influence. Tropical regions are richer in quantity and diversity of wetlands. Aquatic plants SAMPLEare widely distributed in theseCHAPTERS areas, represented by rivers, lakes, swamps, coastal lagoons, and others. These environments also occur in non tropical regions, but aquatic plant species diversity is lower than tropical regions. Colonization of bodies of water and wetland areas by aquatic plants was only possible due to the acquisition of certain evolutionary characteristics that enable them to live and reproduce in water. Aquatic plants have several habits, known as life forms that vary from emergent, floating-leaves, submerged free, submerged fixed, amphibian and epiphyte. -

Received: 20 May 2020; Accepted: 16 June 2020; Published: 18 June 2020 Abstract: The contamination of surface water by pathogenic bacteria of human origin is an important public health issue. Wetlands can be contaminated with fecal bacteria by water originating from different sources, such as wastewater treatment plants and agriculture. Escherichia coli is a commensal of the human gut flora and the major indication of fecal contamination in surface water. Little is known about the association between fecal bacteria and submerged macrophytes and how this may influence the water quality. We questioned whether macrophytes enhance or inhibit the bacterial growth in wetlands. For this purpose, we grew four different species of macrophytes (Mentha aquatica, Baldellia ranunculoides, Sparganium emersum and Elodea canadensis, in mono- or multispecies cultures) in aquatic rhizotrons and inoculated the devices with a fluorescent strain of Escherichia coli (producing a green fluorescent protein) to simulate the fecal contamination of wetlands. -

The single European introduction, Baldellia ranunculoides subsp. repens (creeping water plantain), was discovered by Leila Clase in 2001, in a coastal brackish marsh in Bristol's Hope, eNfld. The only other North American location for this species is in Puget Sound, WA, USA. All of our species are aquatic perennials, rooted in the bottom of streams or shallow ponds; most have leaves that are emergent (extending above the water's surface), but in deeper water, some may have long, flattened, leaf-like petioles (phyllodia) that lack a true blade. Sagittaria cuneata (northern arrowhead) and Baldellia may have floating, emergent, and submersed leaves, depending on the depth of water. Alismataceae -

Phylogenetics and Molecular Evolution of Alismatales Based on Whole Plastid Genomes
PHYLOGENETICS AND MOLECULAR EVOLUTION OF ALISMATALES BASED ON WHOLE PLASTID GENOMES by Thomas Gregory Ross B.Sc. The University of British Columbia, 2011 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIRMENTS FOR THE DEGREE OF MASTER OF SCIENCE in The Faculty of Graduate and Postdoctoral Studies (Botany) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) November 2014 © Thomas Gregory Ross, 2014 ABSTRACT The order Alismatales is a mostly aquatic group of monocots that displays substantial morphological and life history diversity, including the seagrasses, the only land plants that have re-colonized marine environments. Past phylogenetic studies of the order have either considered a single gene with dense taxonomic sampling, or several genes with thinner sampling. Despite substantial progress based on these studies, multiple phylogenetic uncertainties still remain concerning higher-order phylogenetic relationships. To address these issues, I completed a near- genus level sampling of the core alismatid families and the phylogenetically isolated family Tofieldiaceae, adding these new data to published sequences of Araceae and other monocots, eudicots and ANITA-grade angiosperms. I recovered whole plastid genomes (plastid gene sets representing up to 83 genes per taxa) and analyzed them using maximum likelihood and parsimony approaches. I recovered a well supported phylogenetic backbone for most of the order, with all families supported as monophyletic, and with strong support for most inter- and intrafamilial relationships. A major exception is the relative arrangement of Araceae, core alismatids and Tofieldiaceae; although most analyses recovered Tofieldiaceae as the sister-group of the rest of the order, this result was not well supported. Different partitioning schemes used in the likelihood analyses had little effect on patterns of clade support across the order, and the parsimony and likelihood results were generally highly congruent. -

Ireland were contacted in January 2003 and asked whether they would like to participate in the Working Group to produce a new Red List. The core Working Group, from the first meeting held in February 2003, consisted of botanists in Britain who had a good working knowledge of the British and Irish flora and could commit their time and effort towards the two-year project. Other botanists who had expressed an interest but who had limited time available were consulted on an appropriate basis.

Lesser Water-Plantain (Baldellia Ranunculoides) RARE SPECIES RECORDING FORM (PAGE 1 of 4)
Lesser Water-plantain (Baldellia ranunculoides) RARE SPECIES RECORDING FORM (PAGE 1 of 4) METHOD (complete one survey form per pond) Aims: To find out if Lesser Water-plantain is i) present in the pond, ii) get an approximate idea of its location and abundance in the pond, iii) collect physical data about the pond that can be used to assess the reasons for any change recorded on future visits, and iv) look in any adjacent ponds to see if Lesser Water-plantain is present or absent. • Equipment: It’s helpful to take a camera (e.g. mobile phone camera) to take confirmatory photos of Lesser Water- plantain, to take photos of your survey pond for the record, and to take a photograph of your sketch maps if you don’t have access to a scanner – alternatively you can post your survey forms to Freshwater Habitats Trust. • Survey timing: Lesser Water-plantain is best identified and counted once in flower. We therefore recommend visiting the ponds at least once during the flowering season i.e. June through to the end of August. • Where to look: Lesser Water-plantain grows in a variety of wet habitats but prefers spots which are not shaded by scrub and trees. Plants can be found growing amongst other wetland plants, or along muddy margins - often just on the edge of the area poached by cattle. Search for it across all of the pond’s wet and dry marginal areas. • Survey the pond: The selected pond will have a previous record for Lesser Water-plantain, although the plant may not have been recorded since the 1980s. -
Phylogenetic Studies of the Core Alismatales Inferred from Morphology and Rbcl Sequences
Available online at www.sciencedirect.com Progress in Natural Science 19 (2009) 931–945 www.elsevier.com/locate/pnsc Phylogenetic studies of the core Alismatales inferred from morphology and rbcL sequences Xiaoxian Li, Zhekun Zhou * Kunming Institute of Botany, Chinese Academy of Sciences, Kunming 650204, China Received 26 June 2008; received in revised form 16 September 2008; accepted 27 September 2008 Abstract The phylogeny of Alismatales remains an area of deep uncertainty, with different arrangements being found in studies that examined various subsets of genes and taxa. Herein we conducted separate and combined analyses of 103 morphological characters and 52 rbcL sequences to explore the controversial phylogenies of the families. Congruence between the two data sets was explored by computing several indices. Morphological data sets contain poor phylogenetic signals. The homology of morphological characters was tested based on the total evidence of phylogeny. The incongruence between DNA and morphological results; the hypothesis of the ‘Cymodoceaceae complex’; the relationships between Najadaceae and Hydrocharitaceae; the intergeneric relationships of Hydrocharitaceae; and the evo- lutionary convergence of morphological characters were analyzed and discussed.
