    A new combination in Carex is made for Uncinia flaccida S.T.Blake since the earlier name Carex flaccida Sw. ex Wahlenb. is a nomen nudum

    Machaerina ascendens (Cyperaceae), a rare new species from the far south-west of Western Australia, and a new combination for Schoenus abbreviatus Nees

    Get PDF
    We here describe Machaerina ascendens R.L.Barrett & K.L.Wilson as a new species from swamps within forests in the far south-west of Western Australia. The new species is readily identifiable by its scrambling habit and compressed, multi-noded culms, features which separate it from all other Australian species. The clearly distichous glumes, few hypogynous scales fused at the base into a ring and prominently stipitate nutlets are also unusual features in Machaerina Vahl. Machaerina ascendens is highly range-restricted by its specific habitat and appears to qualify for listing as Endangered. Study of all names applicable to the current concept of Machaerina revealed an earlier name for the eastern Australian species Machaerina nuda (Steud.) J.Kern, and a new combination is provided here for Schoenus abbreviatus Nees as Machaerina abbreviata (Nees) R.L.Barrett & K.L.Wilson

    Towards a Comprehensive Survey of C3 and C4 Photosynthetic Pathways in Cyperaceae

    Get PDF
    Members of the family Cyperaceae were surveyed by original observation and from the literature to assess the distribution of C3 and C4 photosynthetic pathways in the family. All 107 genera were included in the current sample, with 91 genera assessed as consistently C3 and 11 genera as C4. The genera Abildgaardia, Cyperus, Eleocharis, Fimbristylis, and Rhynchospora are variable for this trait. Of the total number (1474) of speciļ¬c (1406) and infraspeciļ¬c (68) taxa sampled, 938 taxa (63%) are C3, 527 taxa (36%) are C4, and nine species of Eleocharis are debatably intermediate or variable in pathway. Some data suggesting further infrageneric variation in photosynthetic pathways are discussed. The ā€˜ā€˜one cell distant criterionā€™ā€™ accurately predicts C4 pathway in sedges, except in Eleocharis. Distribution and variability of photosynthetic pathways in Eleocharis are discussed. Photosynthetic pathway was found to be a useful taxonomic marker in Cyperaceae, despite variability in this trait at various taxonomic levels and the apparently multiple origin of C4 photosynthesis within the family. A checklist of 3395 records of C3 and C4 sedges is presented

    The Five-Question Method For Framing A Qualitative Research Study

    Get PDF
    The Five-Question Method is an approach to framing Qualitative Research, focusing on the methodologies of five of the major traditions in qualitative research: biography, ethnography, phenomenology, grounded theory, and case study. Asking Five Questions, novice researchers select a methodology appropriate to the desired perspective on the selected topic. The Method facilitates identifying and writing a Problem Statement. Through taking a future perspective, the researcher discovers the importance and direction of the study and composes a Purpose Statement. The process develops an overarching research question integrating the purpose and the research problem. The role of the researcher and management of assumptions and biases is discussed. The Five-Question Method simplifies the framing process promoting quality in qualitative research design. A course outline is appended

    Stakeholder Experiences in District University Administrator Preparation Partnerships

    Get PDF
    Our qualitative study explores the lived experiences of district stakeholders in university-district leadership preparation programs. Collaborative partnerships between school districts and universities focused on developing quality school leader are a part of recent efforts to provide the field of public education with exemplary leadership. The stakeholder experience in these partnerships is a little understood phenomenon lacking research. Thirteen district stakeholders in grant funded leadership development partnerships participated in the phenomenology informed study. Findings show that prior experiences, trust, issues of time, sustainability, and the power to build bridges were critical components of the district stakeholder experience in partnerships

    Reinstatement and revision of the genus Chaetospora (Cyperaceae: Schoeneae)

    Get PDF
    Three species are recognised in a new circumscription of the genus Chaetospora R.Br. Chaetospora is lectotypified on C. curvifolia R.Br. A new combination, Chaetospora subbulbosa (Benth.) K.L.Wilson & R.L.Barrett is made for Schoenus subbulbosus Benth. Lectotypes are also selected for Chaetospora aurata Nees, Chaetospora curvifolia R.Br., Chaetospora turbinata R.Br., Elynanthus capitatus Nees, Schoenus subbulbosus Benth., Schoenus subg. Pseudomesomelaena KĆ¼k. and Schoenus sect. Sphaerocephali Benth. Two species are endemic to south-western Australia, while the third is endemic to south-eastern Australia. Full descriptions, illustrations and a key to species are provided. All species have anatomy indicative of C3 photosynthetic-type

    Netrostylis, a new genus of Australasian Cyperaceae removed from Tetraria

    Get PDF
    A new genus, Netrostylis R.L.Barrett, J.J.Bruhl & K.L.Wilson is described for Australasian species previously known as Tetraria capillaris (F.Muell.) J.M.Black (Cyperacea tribe Schoeneae). The genus is restricted to southern and eastern Australia, and the North Island of New Zealand. Two new combinations are made: Netrostylis capillaris (F.Muell.) R.L.Barrett, J.J.Bruhl & K.L.Wilson and Netrostylis halmaturina (J.M.Black) R.L.Barrett, J.J.Bruhl & K.L.Wilson. Netrostylis is a member of the Lepidosperma Labill. Clade

    Tropical range extension for the temperate, endemic South-Eastern Australian Nudibranch Goniobranchus splendidus (Angas, 1864)

    Get PDF
    In contrast to many tropical animals expanding southwards on the Australian coast concomitant with climate change, here we report a temperate endemic newly found in the tropics. Chromodorid nudibranchs are bright, colourful animals that rarely go unnoticed by divers and underwater photographers. The discovery of a new population, with divergent colouration is therefore significant. DNA sequencing confirms that despite departures from the known phenotypic variation, the specimen represents northern Goniobranchus splendidus and not an unknown close relative. Goniobranchus tinctorius represents the sister taxa to G. splendidus. With regard to secondary defences, the oxygenated terpenes found previously in this specimen are partially unique but also overlap with other G. splendidus from southern Queensland (QLD) and New South Wales (NSW). The tropical specimen from Mackay contains extracapsular yolk like other G. splendidus. This previously unknown tropical population may contribute selectively advantageous genes to cold-water species threatened by climate change. Competitive exclusion may explain why G. splendidus does not strongly overlap with its widespread sister taxon

    Two new species of Cyperaceae endemic to the ultramafic area of southern New Caledonia are described: Chorizandra gigantea J.Raynal ex K.L.Wilson and Schoenus rivularis J.Raynal ex K.L.Wilson. New combinations are made for three species of Cyperaceae in Australia and New Caledonia: Machaerina johnsonii (K.L.Wilson) K.L.Wilson, M. planifolia (Benth.) K.L.Wilson and M. veillonis (J.Raynal) K.L.Wilso
